Description

tool joint

The present invention relates to a tool joint.

Press, generally during the locking operation, a pneumatic or electric rotating tool is used to assemble the locking piece for locking, and the driving end of the known rotating tool is provided with a driving rod, and the driving rod is assembled with the locking piece. By combining the driving rod with the locking piece, when the driving end rotates, the driving rod can be driven to rotate for locking operation. However, there are many styles of locking pieces (such as screws, nuts and bolts, etc.), so the driving end needs to be replaced with different driving rods in actual operation for assembly with sleeves or other tools in order to lock the nuts or bolts It is very inconvenient to use such locks, and there is a shortcoming that needs to be improved urgently.

Therefore, it is necessary to provide a novel and progressive tool joint to solve the above-mentioned problems.

The main purpose of the present invention is to provide a tool joint that can be connected with an automatic rotating tool and a locking tool, which is not only simple in structure, but also quick and easy to operate.

To achieve the above purpose, the present invention provides a tool joint, which includes a body, an adapter, an elastic element and at least one blocking element. The body is provided with a set of joints, and the set of joints is provided with a through hole in the radial direction. A hole is movably accommodated in the through hole. The adapter is inserted into the main body and can move between a first position and a second position. When the adapter is at the first position, the adapter radially abuts against the locking element so that the locking When the adapter is located at the second position, the adapter does not abut against the clip so that the clip can move radially inward, and the adapter is away from the assembly One end of the part is provided with a set of polygonal connecting holes. The elastic member is sheathed on the part where the adapter is inserted into the main body and abuts between the main body and the adapter so that the adapter normally moves toward the first position. The at least one stopper is disposed on the body to stop the adapter and prevent the adapter from detaching from the body.
