Description

Hand tool drive structure

This creation is a hand tool drive structure, specifically referring to the technology applied in the field of hand tools. It mainly allows users to adjust the drive of hand tools according to the working environment. In addition, it can save space in storage, which is a creation with excellent practicality.

In the era of traditional industry, many jobs still rely on hand tools to complete assembly and disassembly, such as screwdrivers, torque wrenches and other tools. However, these tools are available in different lengths on the market. However, for users, how to carry them lightly is the most important thing. For torque wrenches, because they have related torque components inside, the overall length has a certain proportion and length. However, this type of hand tool will cause a problem for users who often work outside, that is, it is inconvenient to carry, because the type of tools needed by users when working outside is definitely not just one type, so all tools will be packed together in a tool box for easy carrying; However, because the length of torque wrenches is almost always longer than that of common hand tools, Tools, so the installation of toolboxes will cause several problems. First, the length of the toolbox cannot accommodate the torque wrench; second, in order to provide a torque wrench for installation, the length and volume of the toolbox are large, resulting in other shorter hand tools being too scattered and difficult to find, and the larger toolbox is too heavy and too strenuous for users to carry; third, the longer torque wrench is difficult to apply force in the force holding operation, because the force driving angle after the hand holds the torque wrench is not optimal, which limits the driving force; therefore, for today's torque wrenches and other types of hand tools, the driving operation is not the most suitable for users, and relevant industry players need to think again about how to improve to solve the above problems.

The main purpose of this invention is to provide a torque wrench that can save space so that it can be stored together with other types of hand tools, and to provide users with the ability to drive the torque wrench with optimal force in operation, thereby improving the various deficiencies of the aforementioned known torque wrenches in terms of storage and driving operations.

However, in order to achieve the above-mentioned effects and improve the deficiencies of the prior art, the present invention provides a hand tool driving structure, which includes: a tool body, one end of which is concavely formed into a mounting groove; and a driving handle assembly, which is pivoted to the mounting groove of the tool body, and the driving handle assembly includes a connecting piece and a gripping driving piece, one end of the connecting piece is inserted into the mounting groove, and a bolt is passed through the connecting piece and the mounting groove, so that the connecting piece is pivoted relative to the mounting groove of the tool body, and one end of the gripping driving piece is The hinge is arranged at the other end of the connecting member, so that the holding actuator is pivoted relative to the connecting member and moves closer to or farther from the tool body; when the holding actuator is pivoted relative to the connecting member and gradually moves away from the tool body, when the holding actuator is pivoted relative to the connecting member and is in a vertical state relative to the tool body, the holding actuator can be held and a greater force can be utilized based on the principle of the force arm, and when the holding actuator is pivoted relative to the connecting member and approaches the tool body, the overall proportion can be reduced for storage.

In summary, according to the main features described in this creation, its advantage is that, by utilizing the pivoting action of the grip-driven part, the user can further drive the tool body with the best force when gripping and driving, and a storage mode that does not occupy space is provided, thereby providing the user with convenience in carrying, and it will not cause the user burden or affect the operation due to the excessive length. It can be seen that this creation can be said to be a very practical and progressive creation, which is quite worthy of promotion by the industry and public to the public.

In order to clearly illustrate that the present invention can achieve the above-mentioned purpose and effect, the features and effects of the present invention are described in detail with diagrams based on the implementation examples. Please refer to the first to sixth figures, the invention is a hand tool driving structure, which includes: a tool body 1, one end of which is concave to form a mounting groove 11, and the other end of the tool body 1 is provided with a driving part 12 for providing various types of screwdriver heads for installation, such as a flat head, a cross head, a Pozi head, etc.; and a driving handle assembly 2, which is pivoted to the mounting groove 11 of the tool body 1, and the driving handle assembly 2 includes a connecting member 21 and a grip driving member 22, one end of the connecting member 21 is inserted into the mounting groove 11, and a bolt 23 is passed through the connecting member 21 and the mounting groove 11, so that the connecting member 21 is relative to the tool body 1. The mounting groove 11 is pivoted, and one end of the holding driver 22 is pivoted to the other end of the connecting member 21, so that the holding driver 22 pivots relative to the connecting member 21 and moves closer to or farther from the tool body 1; when the holding driver 22 pivots relative to the connecting member 21 and gradually moves away from the tool body 1, when the holding driver 22 pivots and is vertical relative to the tool body 1, the holding driver 22 can be held and a larger force can be utilized based on the principle of the force arm, and when the holding driver 22 pivots relative to the connecting member 21 and approaches the tool body 1, the overall proportion can be reduced for storage.

According to the above description, in terms of operation and use, the user only needs to pivot the gripping actuator 22 relative to the connecting member 21, changing the original gripping actuator 22 close to (adhering to) the tool body 1 to the gripping actuator 22 away from the tool body 1, so that the gripping actuator 22 is in a vertical state relative to the tool body 1. In this way, the user can hold the gripping actuator 22 with his hand, and use the thumb and index finger to press against the top and side of the tool body 1, thereby applying force to drive the tool body 1 in a lateral direction, and the tool body 1 can be driven by the user. The tool body 1 and the grip driver 22 are in a vertical state, so for the user, the force application operation is more reliable and more ergonomic in the force application operation; in addition, when the grip driver 22 is pivoted relative to the tool body 1 and gradually approaches and abuts, this type of configuration is convenient for the user to store in the tool box without occupying the space in the tool box, and the user does not need to use a larger tool box to match the length of the torque wrench as is known, which leads to the inconvenience of carrying.

Based on the above description of the invention, the following further describes other technical features and functions of the invention. First, in order to provide users with a reliable working environment in various workplaces, the outer circumference of the tool body 1 is further inwardly concave with a plurality of receiving grooves 13. Each receiving groove 13 is arranged at intervals and surrounds the outer circumference of the tool body 1. Each receiving groove 13 is a long ellipse and extends from one section of the tool body 1 to the other. At the other end, each storage slot 13 contains at least one accessory 10, which is a screwdriver head with various functions as mentioned above. The user can choose the required accessory 10 according to the construction environment. The drive member 22 of this creation can be relatively swinging relative to the tool body 1. It can be used in more different working environments when carrying. You only need to carry this creation, which is easy and convenient. Please see the first, second and sixth figures.

Continuing with the above, in order to prevent multiple spare parts 10 from falling off during the user's driving and use, the tool body 1 further has multiple partitions 14 formed between the storage grooves 13, and a limit arc groove 141 is cut out in each partition 14. The setting direction of each limit arc groove 141 is different from that of each storage groove 13, and each limit arc groove 141 is at the same horizontal position and is connected to each storage groove 13. In addition, a tie ring 3 is sleeved on the outer periphery of the tool body 1 and is clamped in each limit arc groove 141. Therefore, when each storage groove 13 contains a spare part 10, the tie ring 3 is clamped in each limit arc groove 141 and abuts against each spare part 10, thereby limiting and preventing each spare part 10 from falling off. When the user needs to use the spare part 10, he only needs to tilt the tool body 1 so that one end of the required spare part 10 protrudes from the storage slot 13, and then he can easily pull and pull it out. Then, the spare part 10 that has been removed from the storage slot 13 can be installed on the driving part 12 of the tool body 1 for operation (the method of taking the spare part 10 is not limited to the above method, and it can be carried out in accordance with the user's habit). When the spare part 10 is used, it is also only necessary to simply insert one end of the spare part 10 from the upper and lower sides of the tie ring 3 into the storage slot 13 in a tilted manner to complete the storage. In this way, the user can reduce the number of tools to be carried in various working environments, as shown in the first and sixth figures.

Finally, regarding the setting of the driving handle assembly 2 of the present invention, in order to facilitate the user to easily operate the gripping driving member 22, an assembly groove 221 is further cut out at one end of the gripping driving member 22 pivotally connected to the connecting member 21. One end of the connecting member 21 is inserted into the assembly groove 221 and penetrated by a plug 24, so that the gripping driving member 22 is pivoted relative to the connecting member 21, and the other end of the gripping driving member 22 can be accurately approached or away from the tool body 1 to achieve the effect of operation and easy storage; in addition, in order to cooperate with the user's hand posture in holding and easy operation, the overall design of the gripping driving member 22 is further designed to The part 22 is divided into a small diameter section 222 and a large diameter section 223. One end of the large diameter section 223 is connected to the connecting part 21, and the other end of the large diameter section 223 is connected to the small diameter section 222 or is formed in one piece (the creative diagram is mainly drawn in one piece). The longitudinal cross-sectional circular diameter of the large diameter section 223 is larger than the longitudinal cross-sectional circular diameter of the small diameter section 222 (please see the comparison line segment in the fourth figure). Through the design of the grip driving part 22, the user can concentrate the force on the large diameter section 223 when gripping, and use the small diameter section 222 to stabilize and assist by leaning against the palm of the hand, so that the force can be applied to drive the tool body 1 to rotate.
