After the bearing 8 is installed, an end cover 7 needs to be installed on one side of it to protect and limit it. The convex head 6 on one side of the end cover 7 is docked with the groove inside the rear axle body 2. When the convex head 6 made of rubber material contacts the rear axle body 2, the convex head 6 is deformed. When the convex head 6 enters the groove inside the rear axle body 2, it restores its shape and engages with the rear axle body 2. At this time, the positioning hole on the outside of the connecting block 5 is aligned with the thread inside the rear axle body 2. The holes are aligned, and the first bolt 4 is rotated.
