Thus, the rotating handle 10 can be used as the other force applying end when using the wrench, so that the wrench can rotate for many turns quickly and saves time.
The coupling portion 21 is further provided with an engaging head 25 detachably coupled with the twist grip 10. The rotating handle 10 is provided with a tooth engaging hole 26, and the engaging head 25 is provided with a plurality of engaging teeth 251 in the circumferential direction, the plurality of engaging teeth 251 being engaged in the tooth engaging hole 26. The rotating handle 10 can be easily assembled and disassembled through the engaging holes 26 and the plurality of engaging teeth 251, and is convenient to maintain and replace according to requirements. In this embodiment, the rotating handle 10 is further provided with a plurality of concave-convex structures 11, so that the rotating handle 10 is not easy to slip when rotated.
In more detail, the socket 24 is smaller than the socket 42 and is inserted into the assembling hole 32 of a set of joints 31 of a tool holder 30 without rotating relatively freely, and the set of joints 31 and the socket 42 of the ratchet head 41 are sleeved without rotating relatively freely. Optionally, the coupling head may be designed to fit the size of the hole and may be directly inserted into the hole without rotating freely, and the assembly head of the tool connecting member may be assembled with the coupling head without rotating freely, or the telescopic rod may be further provided with a male joint or a female joint for directly assembling an object to be assembled (e.g., a fastening member). The tool connecting member 30 may be a socket, a connecting rod or a screwdriver bit, and may be used according to the working environment and the type of a fastener 50. In this embodiment, the socket joint 24 is a square head and is inserted into the set hole 32, the socket joint 31 is a square head and is sleeved in the set hole 42 of the ratchet head 41, and the tool connecting member 30 is a sleeve and can be used with the fastening member 50 having an outer hexagonal nut, for example.
