Fastening and folding lightweight tool wrench

The present invention is related to the structure of a tightening and folding lightweight tool spanner, in particular, in a structure of a tightening and folding lightweight tool spanner, the fourth fitting part of the driving rod can be connected with the first set of the first body The fitting part or the third fitting part is fitted together, the drive rod is restricted by the control group and cannot be displaced, the fourth fitting part is fitted with the first fitting part, or the fourth fitting part is fitted with the third fitting The set of the department is indeed.

According to what I have previously known, the conventionally used wrench structure with changeable angle, such as Taiwan patent application number: 103209534, certificate number: M490380, patent name: a hand tool for easy conversion between straight handle and T handle, the structure of the patent case is: A hand tool that is easy to change between a straight handle and a T handle, comprising: a handle 10, the middle section of the handle 10 is provided with an axial slit 11 in the axial direction, and a radial slit 12 in the radial direction, and the aforementioned axial section The groove 11 and the radially sectioned groove 12 communicate with each other; a positioning sleeve 20, the aforementioned positioning sleeve 20 is axially penetrated and provided with a through hole 21, the positioning sleeve 20 is formed with a large diameter end 22 connected to a small diameter end 23; and an actuating rod 30 The perforation 21 of the positioning sleeve 20 can be pierced on the aforementioned actuating rod 30. The end of the actuating rod 30 is provided with a transverse shaft hole 31, and the handle 10 is provided with a through shaft hole 13 at the intersection of the axial slit 11 and the radial slit 12. The actuating rod 30 is inserted into the axial slot 11 and the transverse shaft hole 31 is aligned with the through shaft hole 13, and then a shaft 40 is penetrated and pivotally connected, so that the actuating rod 30 is pivoted on the aforementioned shaft 40 with the shaft 40 as the axis. Between the radial section groove 12 and the axial section groove 11, the front end of the axial section groove 11 of the handle 10 and the front end of the radial section groove 12 are both provided with a first snap groove 111 equivalent to the small diameter end 23 of the positioning sleeve 20, and a Second snap Slot 121, after adjusting the straight handle or T handle by the actuating rod 30, insert the small-diameter end 23 of the positioning sleeve 20 into the first or second buckle grooves 111 and 121 to fix it, which can be used as a straight handle or T handle. You only need to pull out the positioning sleeve 20.

However, the lack of the structure of this patent case lies in:

1. The actuating rod 30 can swing the shaft 40 as the axis between the radial slot 12 and the axial slot 11, the front end of the axial slot 11 of the handle 10 and the radial slot The front end of 12 is provided with the first buckle groove 111 and the second buckle groove 121 equivalent to the small-diameter end 23 of the positioning sleeve 20. After the actuating rod 30 is adjusted with a straight handle or a T handle, the positioning sleeve 20 The small diameter end 23 is inserted into the first buckle groove 111 or the second buckle groove 121 to be fixed, and can be used as a straight handle or a T-handle. When changing, you only need to pull out the positioning sleeve 20. The actuating rod 30 can be rotated to a position. The plurality of damping washers 50 are sheathed between the positioning sleeve 20 and the actuating rod 30 to prevent the positioning sleeve 20 from slipping off instantaneously, but when the user wants to change the straight handle or T When the handle is used, repeatedly pulling out the positioning sleeve 20 will cause the damping washer 50 to rub against the actuating rod 30, and the damping washer 50 will be worn due to friction, making it impossible to prevent the positioning sleeve 20 from slipping off.

2. When the positioning sleeve 20 is displaced on the actuating rod 30, the damping washer 50 will rub against the actuating rod 30. After a period of time, the damping washer 50 will become fatigued and the positioning sleeve 20 will be on the actuating rod 30. The upper automatic sliding movement makes it difficult for the actuating rod 30 to be repositioned at the first buckle groove 111 or the second buckle groove 121.

3. Basically, the action probability of the actuating rod 30 downwardly rotating the screw member is quite high. If the friction force between the damping washer 50 and the actuating rod 30 surface is used as the positioning resistance, if the positioning sleeve 20 is of small size It should be possible that the damping washer 50 is the positioning resistance, but if the positioning sleeve 20 is of a large size, the friction resistance of the damping washer 50 may be less than the weight of the positioning sleeve 20, resulting in the positioning sleeve 20 Gravity automatically slides on the actuating rod 30, so that the actuating rod 30 cannot be fixed to a straight handle or a T handle for use.

4. The cross section of the actuating rod 30 is hexagonal and has six corner ends. The damping washer 50 slides on the actuating rod 30, and the damping washer 50 is easy to move relative to the hexagonal end of the actuating rod 30. Fracture situation.

5. The acting rod 30 is in a fixed length shape. The acting rod 30 cannot be adjusted in length relative to the handle 10 as required. If you want to rotate an object located in a deeper place, the handle 10 and The acting rod 30 may not be able to rotate the acting object due to insufficient length, that is, it is not expandable and practical.

In view of the shortcomings of the above-mentioned conventional structure, the inventors have used years of experience in manufacturing, production and design in related industries to finally have a product with a fastening and folding lightweight tool wrench structure that can solve the drawbacks of the conventional use.

In the hand tools that are easy to change between a straight handle and a T handle, when you want to change a straight handle or a T handle for use, repeatedly pulling out the positioning sleeve will cause the damping washer to rub against the actuating rod, and the damping washer will be rubbed by friction. This causes abrasion, making it impossible to prevent the positioning sleeve from slipping off.
