Therefore, the fixing piece 2 can be clamped to carry out disassembly operation, and the disassembly of the fixing piece 2 is facilitated. Preferably, the outer inclined surface 11 is provided with a first thread section 12, the pressing portion 26 is provided with a second thread section 22, when the second thread section 22 is screwed with the first thread section 12, the first end portion 13 and the collet chuck 10 are firmly combined during the screwing process or the positioning process, and are not easily subjected to any radial deformation relative to the collet chuck 10 by other external forces, so as to stably maintain the size of the opening 14. Wherein, the clamping can be in a clamping, abutting or sleeving manner. In other embodiments, the second thread section may be disposed at an end of the sleeve away from the pressing portion, and the first thread section is disposed at a position of the collet corresponding to the second thread section, that is, the first thread section is not disposed on the outer inclined surface.
The outer bevel 11 is a tapered surface tapering away from the opening.
The first end portion 13 is further provided with a flange 15, the flange 15 protrudes radially inward, the flange 15 is used for clamping the fixing element 2, specifically, the flange 15 can buckle the end edge of the fixing element 2 accommodated in the through hole 21 to facilitate driving and detaching the fixing element 2.
