[0035] The outer sleeve connecting portion is arranged as a plurality of annular protrusions 21 arranged on the top of the main machine 2, and the inner sleeve connecting portion is a protrusion 15 inserted into the annular protrusions 21, so that the protrusion 15 is inserted into the annular protrusions 21 to achieve radial positioning with the annular protrusions 21, thereby ensuring the coaxiality of the main machine 2 and the cup assembly 1, and further improving the stability of the coupling between the upper connecting head 6 and the lower connecting head 5, thereby avoiding the gap between the upper and lower connecting heads 5 due to the low coaxiality of the cup assembly 1 and the main machine 2 caused by the displacement of the cup assembly 1 when placed. Meanwhile, the circumferential positioning structure includes a limiting groove 22 formed between each annular protrusion 21, so that the annular protrusions 21 not only form the outer sleeve connecting portion, but also form the limiting groove 22 between each annular protrusion 21, thereby improving the function of the annular protrusions 21, and eliminating the need for additional structural components to form the limiting groove 22. Meanwhile, the bottom wall of the cup assembly 1 is provided with a limiting column 14 extending downward into the limiting groove 22, so that the limiting column 14 and the limiting groove 22 achieve circumferential abutment, thereby achieving circumferential positioning of the cup assembly 1 and the main machine 2, and the plurality of limiting columns 14 and the plurality of limiting grooves 22 simultaneously abut and limit, which can effectively improve the circumferential positioning effect of the cup assembly 1 and the main machine 2, and further improve the coaxiality of the cup assembly 1 and the main machine 2.

[0036] Further, the number of annular protrusions 21 is not limited in the present application.

[0037] By arranging two annular protrusions 21 symmetrically along the radial direction of the main machine 2, the annular protrusions 21 can exert a symmetrical radial force on the cup assembly 1 after achieving radial abutment with the cup assembly 1, thereby ensuring the coaxiality of the cup assembly 1 and the main machine 2, and avoiding the case that the cup assembly 1 and the main machine 2 have low coaxiality due to uneven radial stress on the cup assembly 1.
