DETAILED DESCRIPTION

[0016] See also Figure 1-4 The utility model provides a technical solution: a combined bearing fixing, including a rotating shaft 1, a bearing body 2 is sleeved on the rotating shaft 1, a first fixing sleeve 3 is sleeved on the rotating shaft 1, a limiting ring 31 is fixedly connected to the inner side of the first fixing sleeve 3, the limiting ring 31 is rotatably connected to the rotating shaft 1, the upper and lower ends of the first fixing sleeve 3 are fixedly connected to a connecting rod 32 passing through the bearing body 2 on one side close to the bearing body 2, a second fixing sleeve 4 is sleeved on the rotating shaft 1, the second fixing sleeve 4 is located on the other side of the bearing body 2, the upper and lower ends of the second fixing sleeve 4 are fixedly connected to a fixing groove 5, a clamping block 6 is slidably connected in the fixing groove 5, the middle part of one end of the clamping block 6 close to the bottom of the fixing groove 5 is fixedly connected to a fixing rod 61 passing through the fixing groove 5, the other end of the fixing rod 61 is fixedly connected to a spherical block 62, a reset spring 7 is sleeved on the fixing rod 61, and the reset spring 7 is located in the fixing groove 5.

[0017] Furthermore, a connecting groove 41 corresponding to the connecting rod 32 is formed on a side of the second adapter sleeve 4 close to the bearing body 2, and an end of the connecting rod 32 away from the first adapter sleeve 3 is located in the connecting groove 41. This facilitates the connection between the first adapter sleeve 3 and the second adapter sleeve 4, thereby facilitating the tightening of the bearing body 2.

[0018] Furthermore, the clamping block 6 is arranged in a trapezoidal structure, the inclined surface of the clamping block 6 faces the bearing body 2, and the inclined surface portion of the clamping block 6 is located in the connecting groove 41, so as to facilitate the clamping of the first adapter sleeve 3 and the second adapter sleeve 4.

[0019] Furthermore, a slot 321 corresponding to the inclined surface of the block 6 is formed at one end of the connecting rod 32 away from the first tightening sleeve 3, so that the block 6 can be easily clamped in the slot 321, thereby achieving the tightening of the bearing body 2.

[0020] Furthermore, one end of the rotating shaft 1 close to the first tightening sleeve 3 is threadedly connected to a limiting sleeve 8, and a bolt 9 passing through the rotating shaft 1 is threadedly connected to the limiting sleeve 8. This facilitates limiting the tightening sleeve and prevents the first tightening sleeve 3 and the second tightening sleeve 4 from being offset.
