In particular, the lower threaded inner sleeve 22 may also be directly integrated with the latch barrel 21 to form a single body.

When in use, the two components are placed closely, and then the locking part 1 is aligned with the plug pin part 2. The operator then extends the tool into the rear end of the bolt barrel 21, engages the hexagonal socket 35 in the adjustment end 31 of the bolt head 3 and pushes the bolt head 3 forward. When the plug head 3 is pushed forward, even if the plug rod 32 and the sliding nut 4 are deviated, the deviation can be corrected by the guiding action of the guiding head 34 and the movement of the sliding nut 4 on the upper threaded inner sleeve 12, so that the threaded end 33 of the plug rod 32 can be aligned with the sliding nut 4. Then the bolt head 3 is screwed, the sliding nut 4 can not rotate through the blocking action of the stopper 41 and the rotation blocking strip 14, and the threaded end 33 and the sliding nut 4 can be screwed in a matched manner by continuously screwing the bolt head 3, and finally the inserting operation between the bolt part 2 and the locking part 1 is completed.

Example two:

referring to fig. 9-11, the main difference between this embodiment and the first embodiment is that the lock sleeve 11 is divided into a threaded sleeve 15 and a profiled sleeve 16, and the slip nut 4 is correspondingly configured as a profiled nut 42.

The lock sleeve 11 comprises a vertical hollow screw sleeve 15 and a special-shaped sleeve 16 which is arranged towards one end of the plug pin part 2 in an opening mode; the special-shaped sleeve 16 is in a vertical polygonal column shape; the threaded sleeve 15 is fixed at the lower end of the special-shaped sleeve 16; the inner diameter of the special-shaped sleeve 16 is smaller than that of the screw sleeve 15; the upper threaded inner sleeve 12 is in threaded connection with the threaded sleeve 15; the sliding nut 4 is a special-shaped nut 42 matched with the special-shaped sleeve 16; said profiled nut 42 being radially movable within said profiled sleeve 16 along said lock sleeve 11; the maximum outer diameter of the special-shaped nut 42 is smaller than the minimum outer diameter of the special-shaped sleeve 16 and larger than the minimum inner diameter of the special-shaped sleeve 16; the latch rod 32 passes through the upper threaded inner sleeve 12, and the threaded end 33 thereof is screwed with the special-shaped nut 42.

According to the above description, as another embodiment of the present invention, the stop block 41 and the rotation blocking bar 14 are replaced by the matching of the special-shaped sleeve 16 and the special-shaped nut 42, so as to achieve the rotation blocking effect. The locking sleeve 11 comprises a threaded sleeve 15 and a special-shaped sleeve 16, wherein the threaded sleeve 15 is used for installing the threaded inner sleeve 12, and a special-shaped nut 42 matched with the threaded sleeve 16 is arranged in the special-shaped sleeve 16. The inner diameter of the special-shaped sleeve 16 is smaller than that of the screw sleeve 15, so that the special-shaped nut 42 can penetrate through the screw sleeve 15; the special-shaped nut 42 can move in the special-shaped sleeve 16, so that the deviation rectification between the bolt rod 32 and the special-shaped nut 42 can be realized; the maximum outer diameter of the shaped nut 42 is larger than the minimum inner diameter of the shaped sleeve 16, and when the shaped nut 42 is rotated to a certain extent, it is locked in the shaped sleeve 16 due to its too long length, so that the threaded end 33 of the latch rod 32 can be locked with the shaped nut 42.

In particular, the profile sleeve 16 preferably has a regular polygonal prism profile.

In particular, the profile sleeve 16 preferably has a regular triangular prism or a regular quadrangular prism.

Particularly, when the special-shaped sleeve 16 is a regular triangular prism, the edge length of the special-shaped nut 42 is greater than the length of the center line of the inner periphery of the special-shaped sleeve 16; when the special-shaped sleeve 16 is a regular quadrangular prism, the length of the diagonal line of the special-shaped nut 42 is larger than the length of the short side of the special-shaped sleeve 16.

When in use, the two components are placed closely, and then the locking part 1 is aligned with the plug pin part 2. The operator then extends the tool into the rear end of the bolt barrel 21, engages the hexagonal socket 35 in the adjustment end 31 of the bolt head 3 and pushes the bolt head 3 forward. When the plug head 3 is pushed forward, even if the plug rod 32 and the special-shaped nut 42 are deviated, the deviation can be corrected through the guiding action of the guiding head 34 and the movement of the special-shaped nut 42 on the special-shaped sleeve 16, so that the threaded end 33 of the plug rod 32 can be aligned with the special-shaped nut 42. Then the bolt head 3 is screwed, the special-shaped nut 42 is clamped in the special-shaped sleeve 16, the special-shaped nut 42 cannot rotate, the bolt head 3 is screwed continuously, the threaded end 33 and the special-shaped nut 42 are screwed in a matched mode, and finally the inserting operation between the bolt part 2 and the locking part 1 is finished.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
