[0027] Furthermore, the end of the shaft column 1 is provided with a stepped structure 11, and the connecting plate 5 is sleeved on the shaft column 1 and abuts against the end face of the stepped structure 11.

[0028] As can be seen from the above description, the stepped structure 11 on the spindle 1 can be designed to limit the installation of the spindle 1 during assembly by abutting against the connecting plate 5.

[0029] Furthermore, the cover plate 3 is engaged with the bearing seat 2.

[0030] As can be seen from the above description, the cover plate 3 and the bearing seat 2 are positioned and connected by snapping together.

[0031] Furthermore, the cover plate 3 is provided with a locking hole that matches the end face of the bearing seat 2, and the cover plate 3 is locked to the end face of the bearing seat 2.

[0032] As can be seen from the above description, the positioning connection between the two is achieved by matching the design of the snap hole of the cover plate 3 with the end face shape of the bearing seat 2.

[0033] Furthermore, the bearing seat 2 is provided with a placement groove 21 at its upper end; the cover plate 3 includes a snap-fit ​​part 31, which snaps into the placement groove 21.

[0034] As can be seen from the above description, the positioning connection between the bearing seat 2 and the cover plate 3 is achieved by the engagement of the placement groove 21 on the bearing seat 2 and the snap-fit ​​part 31.
