A group of inner diameter measuring rulers 14 and a group of outer diameter measuring rulers 13 are slidably connected to the sliding rod 16. The top end of each inner diameter measuring ruler 14 passes through the first through slot 17 and extends to the top of the base plate 1. The top end of each outer diameter measuring ruler 13 passes through the second through slot 18 and extends to the top of the base plate 1. The inner and outer diameters of the bearing can be measured by pulling the inner diameter measuring ruler 14 and the outer diameter measuring ruler 13.

[0024] A fixed block 2 is fixedly connected to the upper surface of the base plate 1, and positioning plates 22 are provided on the left and right sides of the fixed block 2. The side surfaces of the two positioning plates 22 close to each other are fixedly connected to a fixed cylinder 20, and the inner wall of each fixed cylinder 20 is fixedly connected to a spring 21. The ends of the two springs 21 close to each other are fixedly connected to a pillar 19, and the ends of the two pillars 19 close to each other are respectively connected to the left and right side surfaces of the fixed block 2. The elasticity of the spring 21 can be used to push the positioning plate 22, so that the inner diameter of the bearing can be positioned.

[0025] The upper surface of the fixed block 2 is rotatably connected to a threaded rod 9, and the outer surface of the threaded rod 9 is threadedly connected to a pressure plate 6.
