Description

Rotary wrench structure

The invention relates to the structure of a rotary wrench, in particular to a system of a rotary wrench, which is provided with a driving head and is provided with a control member. In addition to the 360 degree rotation of the driving head, the control member can fix the driving head to the body. different angle.

As is known in the prior art, a conventional rotary wrench structure, such as U.S. Patent No. 2,977,824, includes a body (10) having a handle with a Y-shaped end. An arm of the opening, the end of the arm is provided with a first pivot portion, and the longitudinal position of the handle of the body (10) is provided with a groove of a suitable length, and the body (10) is provided at a proximal arm of the body a driving hole (20), a driving head (20) having a second pivot portion (22) at both ends, the second pivot portion (22) being coupled to the first pivot of the body (10) The driving head (20) is pivotally disposed at the arm of the body (10); a fixing member is fixed in the locking hole of the body (10), the fixing is fixed The member is such that the Y-shaped arm of the body (10) is not open to the outside.

The main advantage of the rotary wrench is that the second pivot portion (22) of the driving head (20) is pivoted with the first pivot portion of the body (10), and the fixing member is fixed to the lock of the body (10). In the hole, the fixing member is such that the Y-shaped arm of the body (10) is not open to the outside, and the driving head (20) is greater than 270 degrees with the second pivot as the axis at the arm. In the above swinging, the driving head (20) can rotate the screwing member at an appropriate angle after the sleeve is sleeved, and the rotation angle of more than 270 degrees is a structural feature of the rotary wrench.

The missing feature of the US patented rotary wrench structure is:

1. The driving head (20) is slightly swinged up and down with the second pivot portion as an axis at the arm of the body (10), but if the driving head (20) is provided with a protruding quadrangular head, the fitting portion When rotating, it interferes with the body (10). The driving head (20) cannot rotate 360 degrees. When the four-corner head of the driving head (20) interferes with the body (10), the driving head (20) needs to be reversed. Rotating, such a rotating wrench has a dead angle when rotating, which is not convenient to operate.

2. When the four-head head sleeve of the driving head (20) is driven by the sleeve, the driving head (20) cannot be positioned and controlled relative to the body (10) structure.

In view of the above-mentioned lack of the structure of the conventional rotary wrench, the inventors have years of experience in related industries, and finally have a product that can improve the abuse of the abuse.

The present system of a rotary wrench is provided with a driving head and is provided with a control member. The control member can rotate the driving head at different angles with respect to the body except that the body can rotate 360 degrees.

The second pivot portion is provided with a ratchet, and the two ends of the control member are provided with an engaging portion. When the first pushing portion is pushed, the control member is pushed toward the rod body of the body, and the engaging portion is connected with the spine. The tooth phase is disengaged, and the driving head can be adjusted to various angles relative to the system. When the first pushing portion is released, the control member is abutted by the elastic force of the elastic body, so that the engaging portion of the control member and the driving head are ratcheted.
