The inner walls of both ends of the housing 10 have annular fixing grooves 11, and the side wall of the stop block 40 is fixed in the fixing groove 11. The end opening of the housing 10 is radially constricted at the center, and a thrust ring fixed in the housing 10 is connected to the side of the end plate 20 facing the inside of the housing 10. Specifically, the end plate 20 includes an inner end face 202 and an outer end face 201 that are arranged opposite to each other. The inner end face 202 faces the inner side of the housing 10, and the outer end face faces the outer side of the housing 10. During installation, the thrust ring is first assembled into the housing 10 from the first mounting end. Then, the end plate 20 is installed outside the thrust ring. Finally, the end plate 20 is fixed to the housing 10 by the stop block 40.

[0028] like Figure 3 , Figure 4 , Figure 8 As shown, the stop 40 includes a snap-fit ​​part 41 and a partition part 42; the outer side of the partition part 42 is an arc-shaped snap-fit ​​part 41, and the radial dimension of the snap-fit ​​part 41 is adapted to the radial dimension of the inner wall of the housing 10. The stop 40 is snapped into the fixing groove 11 through the snap-fit ​​part 41; the partition part 42 is provided with a through connecting hole 43; the end plate is provided with a fixing hole 23, which is a threaded hole; bolts are fixed through the connecting hole 43 and the fixing hole 23; at least two fixing holes 23 are provided at intervals along the periphery of the end plate 20, and the number of stop 40 corresponds one-to-one with the number of fixing holes 23; specifically, the end plate 20 is detachably connected to the fixing groove 11 through the stop 40, and multiple fixing holes 23 are provided at equal angles along the periphery of the end plate 20 to make the fixing more secure. The snap-fit ​​part 41 and the partition part 42 are integrally formed.

[0029] The end plate 20 is fixed to the housing 10 by the stop block 40. The stop block 40 has a simple structure and is easy to install and remove.
