In some embodiments, the case 11 is a detachable cavity structure, so as to facilitate disassembly and maintenance.

As shown in fig. 5, in some embodiments, a sliding hole 121 is formed in the center of the back shaft 12 along the axial direction of the back shaft 12, the sliding hole 121 is used for matching the collet 13 to reciprocate in a straight line in the back shaft 12, the sliding hole 121 penetrates through two end surfaces of the back shaft 12, a first sealing member 122 is mounted on the side wall of the sliding hole 121 on the back shaft 12, the first sealing member 122 is used for sealing a gap between the collet 13 and the sliding hole 121, and a matching surface 123 for forcing the collet 13 to close is formed on the back shaft 12 corresponding to the collet 13. Specifically, in the present embodiment, the mating surface 123 is located at an opening position of the slide hole 121 facing outward, the mating surface 123 has a tapered structure, and the inner diameter of the mating surface 123 tends to increase from inside to outside.

Thus, through the above technical solution, when the collet 13 is forced to slide on the back shaft 12 and the pressing surface 132 abuts against the mating surface 123 on the back shaft 12, a pressing force along the substantially radial direction of the collet 13 is generated due to the pressing of the pressing surface 132, so that the clamping end of the collet 13 is forced to deform inwardly and close to clamp the workpiece. The outer sidewall of the collet 13 abuts the first seal 122 on the back shaft 12, thereby forming a seal between the collet 13 and the back shaft 12 to block the passage of foreign matter from the gap between the collet 13 and the back shaft 12.
