Detailed Description

The invention will be further described with reference to specific examples, which are intended to be illustrative only and not to limit the scope of the invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents also fall within the scope of the appended claims.

Referring to fig. 1 to 3, the structure of the present invention, a partial enlarged view of a position a in fig. 1, and a partial enlarged view of a position B in fig. 1, include a locking sleeve, a threaded core, a threaded sleeve, a PVC spool, a limiting groove, a snap ring, an internal thread, an external thread, a knock pin, a spring, and a mounting groove;

the lock sleeve comprises a semi-ring A, a semi-ring B, the semi-ring A is the same as the semi-ring B in structure, the semi-ring A is a fan-shaped ring structure, a snap ring structure is connected to the circumferential surface of the lower part of the semi-ring A, the inner side of the end part of the PVC spool is provided with a threaded sleeve, the inner wall of the threaded sleeve is provided with an internal thread, the inner side of the threaded sleeve is provided with a threaded core, the outer wall of the threaded core is provided with an external thread, the threaded sleeve is in threaded connection with the threaded core, a limiting groove is formed in the inner wall of the threaded core, the inner side of the threaded core is provided with the semi-ring A, the semi-ring B, two mounting grooves are formed in the inner side of.
