The rotating shaft 9 is connected to the mounting ring 2 through-type, and the rotating shaft 9 is also connected to the elastic ring 6 through-type. A mounting frame 11 is rotatably connected between the front and rear parts of the rotating shaft 9. The front and rear sides of the lower part of the mounting frame 11 are slidably connected to the limiting members 12, and the front and rear sides of the lower part of the mounting frame 11 are threadedly connected with adjusting screws 13. The adjusting screws 13 are rotatably connected to the adjacent limiting members 12. The limiting members 12 on the front and rear sides cooperate with each other so that the roller 10 is in a relatively centered position, and the front and rear sides of the roller rack 1 are connected to the limiting plates 14, which are in contact connection with the mounting ring 2.

[0019] It should be noted that the close-fitting cylindrical gear transmission structure is a special mechanical transmission method.

Then the driving device is used to drive the roller 1 0 or the roller rack 1 moves, thereby completing the conversion between linear motion and rotational motion. In order to prevent the roller 10 from being worn out due to long-term movement, causing the roller 10 and the rolling rack to deviate from the set position, mounting brackets 11 are set at the front and rear parts of the rotating shaft 9, and the positions of the front and rear limit members 12 are adjusted by adjusting the length of the adjusting screw 13. The front and rear limit members 12 cooperate with each other to make the roller 10 in a relatively centered position, thereby avoiding the transmission position deviation caused by long-term operation of the roller 10 and the roller rack 1. This is beneficial to improving the accuracy of the transmission operation. In order to further enhance the stability of the movement process of the mounting ring 2, the limiting plate 14 supports the mounting ring 2 so that the mounting ring 2 moves on the limiting plate 14, which is beneficial to enhancing the movement stability of the mounting ring 2.
