[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable light-pulling device, including a light-pulling device body 1, a light-pulling disc 2 installed in front of the light-pulling device body 1, a first sliding groove 7 installed in front of the light-pulling device body 1 by screws, a sliding plate 6 provided in front of the first sliding groove 7, a sliding rail 5 installed above the sliding plate 6 by screws, a movable plate 4 attached above the sliding rail 5, and a connecting seat 3 installed above the movable plate 4 by screws.

[0022] A shaped groove 301 is provided on one side of the connecting seat 3. A threaded rod 302 is fitted inside the shaped groove 301. A fixing buckle 303 is threadedly connected to one side of the threaded rod 302. A support seat 304 is welded to the other side of the threaded rod 302. A rotating shaft 305 is rotatably connected inside the support seat 304.

[0023] A lead screw 708 is inserted into the inside of the first slide groove 7. The output end of the servo motor 709 is installed below the lead screw 708. The outer wall of the lead screw 708 is threadedly connected to the inner wall of the first slider 704. A fixing rod 707 is welded to one side of the first slide groove 7. A sprocket 706 is inserted into one side of the fixing rod 707. A chain 703 is meshed inside the sprocket 706. A connecting block 705 is welded to one side of the chain 703. A second slider 702 is welded to the other side of the chain 703. A second slide groove 701 is attached to the rear of the second slider 702.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the groove 301 has a semi-circular arc shape. The middle of the semi-circular arc groove is divided into two arc-shaped grooves by an insert block. Threaded rods 302A and 302B are horizontally arranged inside the groove 301. The upper connecting seat 3 of the tube pulling device is equipped with a rotating shaft 305, which can hold objects that need to be polished. Because the upper part of the traditional connecting seat 3 is fixed, it cannot be adjusted and cannot adapt to different objects that need to be polished. The threaded rod 302 can move a distance inside the groove 301, making it convenient to adjust the distance between the rotating shafts 305A and 305B.

[0025] In this embodiment, as Figure 3 As shown, cylindrical rods are horizontally provided on both sides of the fixing buckle 303, and the fixing buckle 303 is in the shape of a ring. The fixing buckle 303 has a thread inside, and the internal structural dimensions of the fixing buckle 303 are consistent with the external structural dimensions of the threaded rod 302. The fixing buckle 303 can rotate the surface of the threaded rod 302 clockwise to fix the rotating shaft 305. After adjusting the distance, it can be stably fixed to prevent it from falling.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the lead screw 708 forms a rotating structure through the servo motor 709, and the internal structural dimensions of the first slide groove 7 are consistent with the external structural dimensions of the first slider 704, and the internal structural dimensions of the first slider 704 are consistent with the external structural dimensions of the lead screw 708. The objects to be polished on the table of the polishing device are generally of different sizes, and the distance between the polishing disc 2 and the table needs to be adjusted. Otherwise, the polishing disc 2 will be too close to the table, causing damage to the objects to be polished, resulting in only objects of the same size being polished, thus limiting the polished objects.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, a first slide groove 7 and a second slide groove 701 are horizontally provided at the front of the body 1 of the light-pulling device, and the first slide groove 7 is located in the middle of the body 1 of the light-pulling device. The second slide groove 701 is provided on both sides of the first slide groove 7. Because the two second slide grooves 701 are symmetrically provided on both sides of the body 1 of the light-pulling device, it is convenient to move the slide plate 6 more stably and increase the stability of the moving plate 4.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the second slider 702 forms a sliding structure with the chain 703 through the second slide groove 701; the moving plate 4 moves up and down through the chain 703 connected to the second slider 702, which facilitates the enhancement of the stability of the moving plate 4.

[0029] The method of use and advantages of this utility model: The adjustable light-drawing device operates as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, rotate the fixing buckle 303 clockwise to make the fixing buckle 303 and the threaded rod 302 align. The movable support 304 moves inside the irregular groove 301 to facilitate adjustment of the distance between support 304A and support 304B, thus adapting to different accessory sizes. Place the accessory above the rotating shaft 305, and the servo motor 709 drives the lead screw 708 to rotate clockwise, so that the first slider 704 drives the slide plate 6 to move. The second slider 702 is fixed to support the slide plate 6 through the chain 703, thus fixing and supporting the slide plate 6. Adjust the height of the movable plate 4 connected to the slide rail 5 to facilitate polishing the accessory with the polishing disc 2.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
