Problems solved by technology

[0003] However, the structure of the above-mentioned conventional structure is formed by the opening of the control panel due to the structure of the two clamping blocks, and the two clamping blocks are also guided by an open accommodating groove, and the two open structures are all toward The direction of the main body is open, so the two clamping blocks are very easy to move towards the main body, and it is very easy to cause the lack of both of the two clamping blocks to move towards the main body, thus causing unnecessary clamping, and making the reversing not accurate enough, or even reversing Finally, it is impossible to reliab

Embodiment Construction

[0035] About technology, means and effect thereof that the present invention adopts, preferred embodiment is cited hereby and is described in detail as follows in conjunction with accompanying drawing;

[0036] Please see first Figure 1 ~ Figure 4 Shown is the structure of an embodiment selected by the present invention, which is for illustration only, and the present invention is not limited by this structure.

[0037] refer to figure 1 The ratchet wrench 1 of the present invention includes a wrench handle portion 10, and one end of the wrench handle portion 10 is provided with a driving portion 11, and the driving portion 11 passes through a coupling hole 12 for a driving device 20 to be fastened and combined. The driving part 11 is further provided with a direction control device 40 at a predetermined position adjacent to the coupling hole 12 . By adjusting the deflection of the direction control device 40 , the direction of rotation of the driving device 20 relative to t...
