Specifically, a plurality of circles of mounting holes can be set in the annular mounting area of ​​the base 20, which are nested in sequence from the outside to the inside. The mounting holes can be used to install the first limit assembly 30, the second limit assembly 40 and the adsorption assembly 50. Of course, the mounting holes can also be arranged radially to form a hole group, and then a plurality of hole groups are arranged around the center of the base 20. The hole groups can be arranged radially or in a spiral shape. In addition, a plurality of annular grooves can be set in the annular mounting area, and the annular grooves are nested in sequence. The above-mentioned mounting holes and annular grooves can be used to install the above-mentioned first limit assembly 30, the second limit assembly 40 and the adsorption assembly 50, and the pole frames 12 and mastoid plates 11 of different sizes can be adapted by adjusting the fixed positions of the three.

By slidingly connecting the adsorption component 50, the first limit component 30 and the second limit component 40 with the mounting groove 21, the position of the adsorption component 50, the first limit component 30 and the second limit component 40 can be quickly adjusted.
