The outer wall is provided with external threads A, and the external threads A are in threaded connection with the internal threads of the wire sleeve;

[0008] The adjusting bolt B is inserted into the counterbore at the tail of the adjusting bolt A. A plurality of sector protrusions are evenly arranged along the circumference at the front end of the adjusting bolt B. The sector protrusions are in position cooperation with the L-shaped grooves. The outer circle of the sector protrusion is provided with external threads B, and the external threads B are in threaded connection with the internal threads of the wire sleeve.

[0009] The number and position of the L-shaped grooves are the same as the number and position of the through grooves.

[0010] The number and position of the sector protrusions are the same as the number and position of the through grooves.

[0011] The sector protrusions are the same size as the horizontal grooves of the L-shaped grooves. When the sector protrusions are located in the horizontal grooves of the L-shaped grooves, the external threads B and the external threads A form a complete thread.

[0012] The sector protrusion is located in the transverse groove of the L-shaped groove, and when the external thread A of the adjusting bolt A is located in the through groove, it is used to achieve rapid sliding.

[0013] A circlip groove is provided on the inner wall of the adjusting bolt A, and a circlip is installed in the circlip groove. The circlip is used to limit the sector protrusion.

[0014] The wire sleeve is tubular.

[0016] The utility model adopts the above scheme and has the following beneficial effects:

[0017] By providing a through groove on the inner wall of the wire sleeve, an L-shaped groove on the side wall of the adjusting bolt A, and a sector protrusion at the front end of the adjusting bolt B, the external thread A of the adjusting bolt A and the external thread B of the sector protrusion are both connected in cooperation with the internal thread of the wire sleeve. By rotating the relative positions of the adjusting bolt A and the adjusting bolt B with respect to the wire sleeve, when the sector protrusion is located in the transverse groove of the L-shaped groove and the external thread A of the adjusting bolt A is located in the through groove, the adjusting bolt A and the adjusting bolt B can be quickly slid to a suitable position in the wire sleeve and then locked by rotation. When the sector protrusion rotates into the vertical groove of the L-shaped groove, the adjusting bolt B drives the adjusting bolt A to achieve the normal thread screwing function with the wire sleeve. This structure can not only achieve the rapid adjustment function, but also the entire mechanism has a simple structure and is easy to manufacture, saving time and effort in use.
