Further, the embodiment of FIG. 9 is the same as the embodiment of FIG. 1 and the structure and arrangement of other components of the embodiment of FIG. 6, and the description thereof is omitted here.

In summary, the socket wrench with the direction-changing structure of the present disclosure not only can improve the convenience of operating the socket wrench with the direction-changing structure, but also increases the bite strength between the shaft and the sleeve member. , the torque strength of the socket wrench with direction switching structure is increased. This increases the versatility of use of the socket wrench with the direction switching structure.

Although the present invention has been disclosed by the above embodiments, they are not intended to limit the invention and those skilled in any technical field may make some changes and modifications without departing from the spirit and scope of the invention. and the protection scope of the present invention shall be as defined by the appended claims.
