Description

adjustable wrench tool structure

technical field

The utility model relates to a hand tool, in particular to an adjustable wrench tool structure capable of providing extended driving functions.

Background technique

The most commonly used equipment for many operations in the industry is hand tools. Although some highly technical and dangerous operations have been gradually replaced by machines, basic processing and maintenance must be completed with the assistance of hand tools. Therefore Manufacturers from all over the world are developing hand tool structures that are simpler, more humane, and have lower manufacturing costs.

According to different operations and environmental requirements, the shape of hand tools will naturally change. Generally, a common adjustable wrench is equipped with a fixed jaw and a movable jaw at the front end of a grip part. The movable jaw is connected to the fixed jaw with a screw. Movable setting, when the user adjusts the screw, the movable jaw can move closer to or away from the fixed jaw, so that the distance between the two jaws can be changed according to the size of the object to be clamped, so as to provide the effect of convenient clamping and applying force, and also Because the adjustable wrench is very easy to use, many people in the industry have improved it, adding components or changing the structure to make it produce additional effects.

For existing adjustable wrenches, please refer to the patent application No. 91210322 "Ratchet structure of adjustable wrench" in Taiwan, China. It is a ratchet structure of adjustable wrench, which mainly includes a handle body. adjustable wrench part, and the other end is provided with a holding hole, and one end of the holding hole is provided with a space part, and the space part accommodates an elastic part and a stop block, and the holding hole is for accommodating a ratchet block, and the inner periphery of the ratchet block is provided with There are ratchet catches of different sizes, and the outer peripheral ring is provided with ratchet teeth, and one end of the ratchet block is provided with a concave ring groove, one side of the buckle is clamped in the concave ring groove, and the other side is stuck against the container The hole is opposite to the abutment of the recessed ring groove, so that the ratchet body can be fixed in the hole; the end of the stop block opposite to the ratchet is provided with a claw, and the claw is engaged with the ratchet.

Although this kind of adjustable wrench can provide the effect of both movable clamping and ratcheting turning, its ratchet block can only pull the locking parts that can be locked with the outer diameter type, but in fact the types of locking parts are highly diverse. Variability, from screws, nuts, extension rods to sleeves, etc., are all gradually extended and evolved in response to job requirements or to overcome operational difficulties, and even locking pieces are differentiated and have various types due to different job objects. The same size and type, and the ratchet block of this kind of adjustable wrench does not have the function of extending and driving. If it encounters a locking piece whose outer diameter cannot be firmly combined with the ratchet block, this kind of adjustable wrench is useless. Obviously, its The type of locking element suitable for turning is quite limited, so its practicability is poor. It is necessary to develop a design that can provide extended driving function in addition to the ratchet turning function.

Detailed ways

The utility model relates to a tool structure of an adjustable wrench, as shown in Fig. 1 to Fig. 3a, which mainly includes a wrench body 1 and a fitting block 2 for driving, wherein:

The wrench body 1 includes a handle portion 11, a movable pulling portion 12 and an accommodating portion 13. The movable pulling portion 12 is arranged at one end of the handle portion 11, and includes a fixed jaw 121, a movable jaw 122 and a screw 123, the movable jaw 122 is movably assembled with the fixed jaw 121 by the screw 123, when the screw 123 is adjusted, the movable jaw 122 changes with the rotation of the screw 123 and The clamping distance of the fixed jaw 121, so it can be used by using the fixed jaw 121 and the movable jaw 122 to pinch the locking piece (the locking piece refers to screws, nuts, sleeves, etc., which can be driven to apply force to the object) In addition, the accommodating part 13 is provided at the other end of the handle part 11, which is used for the fitting block 2 to enter and set;

This fitting block 2 comprises a ratchet part 21, and this ratchet part 21 is provided with a first driving part 22, and the other side is provided with a dial 23 with outer diameter larger than it, and this dial 23 is opposite to the ratchet part. The other side of 21 is provided with a second driving part 24, and the first driving part 22 is provided with a limit groove 221 adjacent to the ratchet part 21, so when the fitting block 2 enters the accommodating part 13 and is set, the ratchet The part 21 is assembled in the inner side of the accommodating part 13 in a ratchet state, and the first driving part 22 and the second driving part 24 are respectively protruding from the two sides of the accommodating part 13, and the dial The disc 23 is against the side outside the accommodating portion 13, so that the user can turn the dial 23 to rotate the fitting block 2 as a driving function, and the limiting groove 221 can be used for a C-shaped fastener 222 is embedded and fixed, and the fastener 222 is used to abut against the other side outside the accommodating part 13, and can produce the effect of clamping the first driving part 22, so that the first driving part 22 and the accommodating part 13 are mutually It is fixed and cannot be moved, so as to prevent the fitting block 2 from dislodging relative to the accommodating part 13; in addition, the first driving part 22 and the second driving part 24 can be the same type of tool head with different sizes, or each Different types of tool head shapes, so that users can choose the appropriate first driving part 22 or second driving part 24 to work directly according to the situation, or use the first driving part 22, second driving part 24 and tool extension group Then, the effect of extending the driving is provided, that is, as shown in this embodiment, the first driving part 22 and the second driving part 24 are the same D head tool head type, but they are each different in size, so the user The first drive part 22 or the second drive part 24 can be selected to be extended and plugged with other tools, and can be used as an extension drive, which makes the utility model more convenient to use;

A control mechanism 3 is located in the accommodating part 13, which includes a ratchet block 31, a steel ball 32 and an elastic member 33, wherein one end of the ratchet block 31 is unidirectionally toothed and fits with the joint block 2 The ratchet part 21 is engaged, and the other end is against the steel ball 32, and the two ends of the elastic member 33 are respectively against the inner side of the accommodating part 13 and the steel ball 32. When the direction of the tooth shape is rotated, the ratchet block 31 is pushed by the ratchet part 21 without affecting the rotation effect of the ratchet part 21, and the ratchet is made by the abutment of the steel ball 32 and the back and forth compression and reset of the elastic member 33. The block 31 returns to its original position immediately after being pushed; and when the ratchet part 21 rotates in the direction opposite to the tooth shape of the ratchet block 31, the ratchet block 31 and the ratchet part 21 are engaged with each other so that the ratchet part 21 cannot rotate. Therefore, the unidirectional tooth structure of the ratchet block 31 and the effects of the steel ball 32 and the elastic member 33 provide the effect of the utility model that the sleeve block 2 can perform one-way ratchet rotation, thereby being available for use. It is convenient to turn the handle portion 11 back to an angle that is convenient for applying force and then apply force again for use.

When the utility model is in use, as shown in Fig. 4, the first drive part 22 of the fitting block 2 is plugged and combined with a sleeve tool head 4, so the user can use the sleeve tool head 4 to connect with the screw. The fastener 5 is sleeved and combined, and exerts force on the handle 11 to transmit the pulling power to the sleeve tool head 4 through the fitting block 2, and the sleeve tool head 4 applies a turning force to the screw member 5 to make it relatively desired. The locking object is fixed and locked, so the utility model can provide the extension driving effect through the first driving part 22 and the second driving part 24 of the fitting block 2, thereby greatly improving its practicability.
