The first side surface 314 corresponds to the third side surface 316. The second side surface 315 is opposite to the first side surface 317. The sleeve hole 311 is formed in the end surface 313. The hole 312 is formed in the first side surface 314. The sleeve hole 311 is located on the end surface 313 adjacent to the first side surface 314. A recess 318 is formed therein for the snap-on device 24 to be easily removed from the drive head 30, and the recess 318 allows the snap-in device 24 to slide easily into the drive head 30.

Referring to FIG. 6 at the same time, the schematic diagram of the bearing member of the wrench of the present invention capable of receiving different specifications of the driving head. The receiving member 20 can receive the driving heads 30 of different specifications, and the driving end 32 of each of the driving heads 30 can be set to various specifications, and the user can select the driving head 30 according to the specification to receive the receiving member 20 for the user. It can be received by one of the plurality of driving heads 30 by a single handle 10 and a single receiving member 20, further satisfying the requirements of a plurality of driving parts to be driven.

As far as the above is concerned, it can be concluded that the present invention has the following advantages:

1. The wrench of the present invention can support different types of driving heads, and the driving end of each driving head can be set to various specifications, and the user can select a driving head conforming to the specification to receive the receiving member, so that the user It can be supported by one of a plurality of driving heads by a single handle and a single receiving member, and further meets the requirements of a plurality of driving parts to be driven.

2. The wrench of the present invention can be switched between a socket position and a disengagement position. When the socket end is in the socket position, the socket end is sleeved on the insertion end, and the card is offset. Abutting the socket end, the driving head is not separated from the receiving member; when the socket end is in the disengaged position, the user presses the card abutting device to disengage the socket end from the insertion end, and the driving head is Get detached from the socket.

3. The wrench of the present invention has a recess at the socket end, the recess for the snap-on device to be easily detached from the drive head, and the recess for the snap-fit device to slide easily into the drive head.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so that the numerical value is changed or the equivalent element is replaced, or the equivalent of the scope of the patent application of the present invention.
