The clamping portion is the outwardly protruding portion of the outer surface of the clamping section 6.

By means of the design, the clamping section 6 can be effectively prevented from rotating in the installation position 4.

Simultaneously, the axial fixing part can be a limiting bulge 21 formed at the end part of the clamping section 6, and after the clamping section is inserted into the installation position, the limiting bulge 21 abuts against the inner wall of the shell, so that the axial direction of the fixing component is limited.

Example 3:

the structure of this embodiment is basically the same as that of the other embodiments, and the difference is that: the clamping piece can also be a clamping spring.

Example 4:

the structure of this embodiment is basically the same as that of the other embodiments, and the difference is that: parallel arrangement on the both sides of the vertical direction of annular groove 14's bottom forms the shape of similar track and field runway, like this when joint spare 13 joint to annular groove 14 in the back, can not take place to rotate between the two, simultaneously because the design of the spacing groove on the end cover, can guarantee fixed component radial and axial spacing on the casing.
