Embodiment Construction

[0046] refer to Figure 1 to Figure 3 , the ratchet wrench 10 of the present invention includes a body 20, a driving body 30, a ratcheting device 40, a control member 50 and a positioning device 60; wherein:

[0047] The body 20 has a handle 21 and a head 22 arranged at one end of the handle 21. A circular first accommodation groove 23 is provided in the head 22. The first accommodation groove 23 has an axis L23, and the user The main body 20 can be rotated around the axis L23 of the first accommodating groove 23 by operating the handle 21 . The head 22 is provided with a first stop wall 25 and a second stop wall 26 opposite to each other, and the head 22 is formed with a first plane 251 on the outer surface of the first stop wall 25, and the head 22 is formed on the second stop wall 26. A second plane 261 is formed on the outer surface of the body. The first plane 251 and the second plane 261 are parallel to each other and spaced apart from each other and perpendicular to th...

Abstract

The invention provides a ratchet wrench. The invention has the following beneficial effects: through the design that a first control block and a second control block of a control element are directly linked with a first clamping and pulling block and a second clamping and pulling block of a ratchet device, the ratchet wrench can achieve high flexibility action and real-time reaction; one end of the meshing section of a driving body, which is close to a pivot column is adjacent to and contacted with the first retaining wall of a body and the inside surface of the control element is adjacent to and contacted with the first plane of the first retaining wall; therefore, the control element is still quite easy to change, and meanwhile, the control element is free from wear caused by friction of the end face of the rotating driving body, thus the control element is smoother to use and the service life of the control element can be prolonged; and the first plane of the body is provided with a containing slot which is close to a first containing slot but far from a second containing slot and is used for containing a locating device, thus reducing the gap between the control element and the body and prolonging the service life of the ratchet wrench.

Description

technical field [0001] The invention relates to a wrench tool, especially a socket ratchet wrench with a control part pivotally arranged on a driving body, which has the effects of sensitive operation, precise control and improved service life. Background technique [0002] Please refer to the "Reversible Ratchet Wrench" patent case of US Patent No. 7,278,339, which is a reversible ratchet wrench. This ratchet wrench uses a ring to drive a switching member to produce position changes in two directions, and the front end of the switching member is equipped with a pressing member and an elastic element to elastically push the trigger A pawl allows the pawl to be controlled to move between two positions and engages a drive member. [0003] Firstly, it can be noticed that the reversing ratchet wrench uses a reversing plate to perform the reversing action, and the reversing plate is pivoted on the rotating assembly and can be operated by the user. [0004] However, there are qu...
