The surface of the base plate 1 is precisely processed to ensure the accuracy of the installation position of each component. The two support plates 2 are vertically fixed to both sides of the base plate 1 by high-strength bolts. The support plates 2 are designed with reinforcing ribs inside to improve their bending strength and stability. A certain distance is maintained between the support plates 2 to provide sufficient movement space for the sliding component. The threaded rod 3 is made of high-precision, wear-resistant alloy steel and is rotatably connected between the two support plates 2 through precision bearings. One end of the threaded rod 3 extends out of the support plate 2 to facilitate connection to an external power source. A convex slide groove is opened in the center of the bottom plate 1, parallel to the sliding direction. The convex slider 19 is made of low-friction material to ensure low resistance and smooth movement during sliding.

[0052] Then, see Figure 3 In this embodiment, the rotating shaft 10 in the rotating assembly is rotatably connected to the inner wall of the carrying frame 7, the gear 11 is fixedly connected to the rotating shaft 10, and the gear 11 is engaged with the rack 9, the worm wheel 12 is fixedly connected to the rotating shaft 10, the worm 13 is rotatably connected to the inner wall of the carrying frame 7, and the worm 13 is engaged with the worm wheel 12, and the rotating handle 14 is fixedly connected to the worm 13, and the rotating handle 14 is engraved with a scale.

The rotating handle 14 is engraved with a scale for indicating and adjusting the position of the limiting ring 8 to achieve precise sliding distance control.

[0054] Finally, see Figure 2 In this embodiment, the first rotating rod 15 in the driving assembly is rotatably connected to the rotating handle 14, the mounting block 16 is fixedly connected to the side of the base plate 1, the second motor 17 is mounted on the mounting block 16, the second rotating rod 18 is fixedly connected to the output shaft of the second motor 17, and the second rotating rod 18 is rotatably connected to the first rotating rod 15.

[0056] Working principle:

[0057] When the sliding distance of the sliding plate 4 needs to be adjusted, the worker first starts the second motor 17 of the transmission screw with a limiting sleeve. The second motor 17 starts to drive the second rotating rod 18 to rotate, and the second rotating rod 18 rotates to drive the first rotating rod 15 to rotate. The first rotating rod 15 rotates to drive the rotating handle 14 to rotate. The rotating handle 14 rotates to drive the worm 13 to rotate. The rotation of the worm 13 drives the worm gear 12 to rotate. The rotation of the worm gear 12 drives the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the gear 11 to rotate. The rotation of the gear 11 drives the rack 9 to move. The movement of the rack 9 drives the limiting ring 8 to move, so that the limiting ring 8 moves to the appropriate position.

[0058] When the sliding plate 4 needs to be moved, the worker first starts the first motor 6. The first motor 6 starts to drive the threaded rod 3 to rotate, and the rotation of the threaded rod 3 drives the sliding plate 4 to move. At the same time, the movement of the sliding plate 4 drives the convex slider 19 to slide in the convex slide groove to complete the movement of the sliding plate 4.

[0059] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0060] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
