[0002] Plastic products refer to the process of making plastic raw materials (such as polyethylene, polypropylene, polyvinyl chloride, ABS, etc.) into daily necessities, industrial parts or other products with certain shapes and functions through various processing methods.

[0003] Plastic products are widely used in all aspects of life, including but not limited to household items, packaging materials, electronic appliances, auto parts, medical devices, etc.

[0004] Plastics generally have a low density, and the products made from them are light and easy to carry and transport. Most plastics have good chemical stability and are not easily corroded by acids and alkalis. Plastics have excellent electrical insulation properties and are suitable for making casings for electrical and electronic equipment.

[0005] Currently, after the mold base of a plastic product is produced, the outer wall surface needs to be polished and leveled to remove barbs or protrusions caused by sticking after the plastic product is demolded. The distributed plastic products have an irregular structure. If they are not fixed during the polishing process, they are prone to random movement. Therefore, a fixed structure of a fixture needs to be designed to facilitate the positioning of the plastic products. Utility Model Content

[0028] A first limiting sleeve 18 is fixedly provided on both the front and rear ends of the center platform 10, and a first limiting rod 17 is slidably sleeved on the inner side of the first limiting sleeve 18. The upper end of the first limiting rod 17 is fixed to the center lifting plate 12 by screws, and a first anti-slip block 19 is fixed to the lower end of the first limiting rod 17.

[0029] It should be further explained that an extension platform 20 is provided on both sides of the center platform 10 , one end of the extension platform 20 is fixed to the edge of the center platform 10 by screws, and an edge lifting plate 21 is provided above the extension platform 20 .

[0030] It should be further explained that a second threaded sleeve 24 is fixedly passed through the middle position of the extension platform 20, and the inner thread of the second threaded sleeve 24 is connected to the second threaded rod 23, and the lower end of the second threaded rod 23 is fixed with a second handle 25. The lower end of the edge lifting plate 21 is fixed with a second bearing 22 located in the middle position, and the inner ring wall of the second bearing 22 and the second threaded rod 23 have an interference fit with each other. The second handle 25 can be shaken to make the second threaded rod 23 and the second threaded sleeve 24 move threadably with each other, so that the clamping height point can be adjusted according to the actual shape and position of the plastic product.

[0031] It should be further explained that a second limiting sleeve 26 is fixed on both sides of the extension platform 20, and a second limiting rod 27 is slidably sleeved on the inner side of the second limiting sleeve 26. The upper end of the second limiting rod 27 is fixedly installed on the edge lifting plate 21, and a second anti-slip block 28 is fixed to the lower end of the second limiting rod 27. The second limiting rod 27 slides in the second limiting sleeve 26 to ensure that the straight up and down movement of the edge lifting plate 21 is stable.

[0032] It should be further explained that a positioning plate 30 is fixed to the upper end of the edge lifting plate 21, and a third threaded sleeve 31 is fixed inside the positioning plate 30. The inner thread of the third threaded sleeve 31 is connected to a third threaded rod 32, and one end of the third threaded rod 32 is fixed to a third handle 33. Through the mutual threaded movement of the third threaded rod 32 and the third threaded sleeve 31, a stable forward and backward displacement of the extrusion plate 34 can be achieved.

[0033] It should be further explained that an extrusion plate 34 is fixed to the other end of the third threaded rod 32, and a built-in groove is provided on the surface of the extrusion plate 34, and an extrusion pad 35 made of rubber material is provided inside the built-in groove, and a card slot 40 is provided inside the extrusion pad 35, and an elastic card 41 is fixed on the inner wall of the built-in groove of the extrusion plate 34, which is engaged with the card slot 40.

[0034] It should be further explained that a lighting lamp 50 is fixed on one side of the positioning plate 30 facing the central lifting plate 12. The lighting lamps 50 are symmetrically distributed along both sides of the positioning plate 30. The lighting lamps 50 can provide a fill light effect when polishing plastic products.

[0035] Working method: When it is necessary to fix the plastic product during polishing, the plastic product is first placed on the central lifting plate 12. Then, according to the shape and height of the plastic product, the first handle 16 can be used to rotate the first threaded rod 14, so that the first threaded rod 14 and the first threaded sleeve 13 can be threadedly moved relative to each other, thereby achieving the up and down adjustment of the central lifting plate 12. The first limiting rod 17 slides in the first limiting sleeve 18, so that the central lifting plate 12 can move straight up and down.

[0036] By rotating the second handle 25, the second threaded rod 23 and the second threaded sleeve 24 can move relative to each other, thereby adjusting the up and down movement of the edge lifting plate 21. The second limiting rod 27 slides in the second limiting sleeve 26 to ensure that the edge lifting plate 21 moves straight up and down.

[0037] The third handle 33 can be used to drive the third threaded rod 32 and the third threaded sleeve 31 to move relative to each other, thereby advancing the extrusion plate 34. The extrusion plates 34 distributed on both sides can clamp and position the plastic product. The lighting lamp 50 can be used to provide fill light during polishing. The elastic card 41 and the card slot 40 are engaged and assembled with each other, so that the extrusion pad 35 of the extrusion plate 34 can be easily replaced and regularly cleaned.
