It should be noted that, the number of the third clamping portions and the fourth clamping portions is not limited, the third clamping portions and the fourth clamping portions are in one-to-one correspondence, and the clamping effect is better when the plurality of third clamping portions and the plurality of fourth clamping portions are in simultaneous clamping fit.

In the embodiment of the present utility model, the plurality of index numbers includes two or more.

It can be understood that, referring to fig. 3 and fig. 4, when the number of the third clamping portions is plural, all the third clamping portions are uniformly distributed in the circumferential direction of the connecting member 30, so that when the connecting member 30 is connected with the base 20, the stress is more uniform and the connection is more stable.
