[0026] The limiting assembly comprises three movable grooves 21, limiting holes 211, a connecting groove 22 and a central shaft 23. The three movable grooves 21 are equidistantly arranged in the inner part of the fixed table 15. The limiting holes 211 are arranged at the outer ends of the movable grooves 21 and communicate with the movable grooves 21. The connecting groove 22 is arranged on the upper surface of the fixed table 15. The central shaft 23 is fixed to the center of the upper surface of the fixed table 15.

[0027] The movable grooves 21 provide space for the sliding of the movable rods 25. The limiting holes 211 are used to limit the moving range of the movable rods 25. The connecting groove 22 provides a channel for the sliding of the limiting rods 28. The central shaft 23 provides a reference for the pressing of the bearing 16.

[0028] The limiting assembly further comprises three square grooves 24, which are equidistantly arranged on the outer surface of the central shaft 23. The limiting assembly further comprises movable rods 25, baffle plates 26 and springs 27. The movable rods 25 slide through the movable grooves 21 and the limiting holes 211. One end of the movable rods 25 is fixed with the baffle plates 26. One side of the baffle plates 26 is fixed with the springs 27.

[0029] The square grooves 24 cooperate with the movable rods 25 to limit the position of the bearing 16. The movable rods 25 are used to control the position of the limiting rods 28.

The lower end of the connecting rod 33 is slidably arranged in the mounting groove 31.

[0034] The mounting groove 31 provides a space for the lower end of the connecting rod 33 to be slidably arranged. The fixing holes 32 can adjust the position of the connecting rod 33 on the limiting rod 28 and fix it, so as to realize the accurate adjustment of the height or position of the limiting rod 28. By sliding the connecting rod 33, the length of the limiting rod 28 in the vertical direction can be extended, so as to adapt to the appropriate bearing 16.

[0035] The lower end of the connecting rod 33 is provided with a connecting hole 34 corresponding to the fixing hole 32. The fixing hole 32 and the connecting hole 34 are penetrated by a fixing bolt 35. The connecting hole 34 serves as a connecting interface between the connecting rod 33 and the limiting rod 28. The fixing bolt 35 plays a locking and fixing role.

[0036] In this embodiment, when the bearing 16 is placed in the fixed table 15, then the worker pulls the connecting rod 33, so that the lower end of the connecting rod 33 corresponds to the appropriate fixing hole 32. Then the fixing bolt 35 is passed through the fixing hole 32 and the connecting hole 34, so as to fix the height of the connecting rod 33. This is convenient for limiting the bearing 16 of different heights.
