[0029] On the basis of Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods. As Figures 1 to 4 shown, see the following description for details:

[0030] As a preferred implementation method, the inner diameter of the socket 2 is smaller than the inner diameter of the installation groove 3, and the socket 2 and the installation groove 3 are of a connected design; further, the design with a smaller inner diameter than the installation groove 3 makes it difficult for the built-in threaded sleeve 4 to fall off after assembly, and the design is more reasonable. The connected design facilitates the built-in threaded sleeve 4 to enter the installation groove 3 through the socket 2, and the assembly is more convenient.

[0031] As a preferred embodiment, the inner surface of the built-in threaded sleeve 4 is provided with an internal thread 401 adapted to the brass kit 6, and the outer wall of the built-in threaded sleeve 4 is in contact with the inner wall of the installation groove 3; further, the contact design makes the built-in threaded sleeve 4 more stable and not easy to fall off in the installation groove 3, and the assembly is more convenient.

[0032] As a preferred embodiment, the built-in threaded sleeve 4 is composed of three thread sleeve segments 9 distributed in an annular array, and a limiting strip 901 is provided at the central position of the outer surface of each thread sleeve segment 9. The inner surface of the installation groove 3 is equally angled with a limiting groove 301 adapted to the limiting strip 901; further, the three thread sleeve segments 9 of the built-in threaded sleeve 4 are moved to the accurate position in the installation groove 3, and the limiting strip 901 on the thread sleeve segment 9 is snapped into the limiting groove 301 to complete the fixation of the thread sleeve segment 9. While the assembly is more convenient, it also makes the thread sleeve segment 9 not easy to loosen or fall off when replacing the brass kit 6, and the design is more reasonable.

[0033] As a preferred embodiment, the brass kit 6 includes an integrally formed screw part 601 and an installation table 602, and the outer diameter of the screw part 601 is consistent with the inner diameter of the socket 2; further, the screw part 601 is used for threaded connection with the built-in threaded sleeve 4, the installation is more convenient, and it is easy to disassemble, assemble and reuse.

[0036] The working process of the present utility model is as follows:

[0037] During use, first, the internal threaded sleeve 4 is retracted to its minimum diameter. At this time, the three threaded sleeve segments 9 are engaged with each other through the locking blocks 902 and the locking grooves 903. The internal threaded sleeve 4 in the retracted state is inserted into the installation groove 3 through the socket 2. Then, an installation workpiece 5 is sleeved outside the installation section 8. By rotating the installation workpiece 5, the magnetic suction force of the installation workpiece 5 can attract the threaded sleeve segments 9 and move them to the accurate positions in the installation groove 3. The limiting strips 901 on the threaded sleeve segments 9 are snapped into the limiting grooves 301 to complete the fixation of the threaded sleeve segments 9.
