The aperture of the conical hole is gradually reduced from one end close to the shell to the direction far away from one end of the shell, namely the conical hole is a conical hole with smaller aperture far away from one end of the shell. The tapered hole may extend through the entire taper sleeve 112, or a portion of the hole of the taper sleeve 112 may be a tapered hole and the other portion of the hole may be a cylindrical hole. In this embodiment, only the holes at the end far away from the housing are tapered holes, and the holes at other positions are cylindrical holes.

However, in order to ensure that the overhanging threaded end of the screw mechanism assembly 101 can be inserted into the threaded hole, it is necessary to ensure that the major diameter of the overhanging threaded end of the screw mechanism assembly 101 is smaller than the minor diameter of the threaded hole. It should be noted that the difference between the two is not too large, and it is necessary to ensure that the screw mechanism assembly can be clamped by the deformation of the threaded hole when the clamping jaw 111 moves downward.
In one embodiment of the present invention, the material of the clamping jaw 111 is spring steel, in particular 65Mn spring steel. It should be noted that the material of the clamping jaw 111 may also be other materials with elasticity, and is not limited to the above spring steel.
