The position of the threaded column 4 can be moved under the rotation of the bolt 9, and a spring 5 is provided on the outside of the threaded column 4, and one end of the spring 5 is fixedly connected to one side of the inside of the slide groove 3.

[0033] Reference Figure 3-4 The other end of the spring 15 is fixedly connected to the outside of the threaded column 4. The threaded column 4 is adjusted according to the degree of extrusion of the block 8. When the product is placed in the inside of the placement groove 10, the outside will squeeze the block 8. At this time, the bolt 9 is rotated according to the shape of the product. The rear end of the threaded column 4 is fixedly connected with the push block 6 to move the position of the push block 6. The outside of the push block 6 is slidably connected to the limit block 7. At this time, the push block 6 will drive the limit block 7 to move. The outside of the limit block 7 is slidably connected with the block 8. The position of the block 8 can be adjusted under the movement of the push block 6 and the limit block 7 to adapt to the shape of the product. The outside of the block 8 is slidably connected to the outside of one side of the push block 6. A placement groove 2 11 is provided on the top left side of the bottom plate 1, and a placement groove 3 12 is provided on the top right side of the bottom plate 1. Then, the products are placed on the outside of the placement groove 2 11 and the placement groove 3 12 in turn;

[0034] Reference Figure 2 and Figure 5 A locking assembly is provided on the inner rear side of the base plate 1, and the locking assembly includes a fixing frame 13. The outside of the fixing frame 13 is fixedly connected to the inner rear side of the base plate 1, and the inside of the fixing frame 13 is slidably connected to two moving columns 14. At this time, the moving column 14 will be squeezed. According to the appearance and shape of the product, the moving column 14 will be squeezed to different degrees. A spring 2 15 is fixedly connected to the outer side of the moving column 14. At this time, the spring 2 15 will be compressed. The other end of the spring 2 15 is fixedly connected to the outer side of the fixing frame 13. A limiting groove 16 is provided inside the moving column 14, and the inner wall of the limiting groove 16 is slidably connected to the limiting rod 17. As the moving column 14 moves, the internal limiting groove 16 will drive the limiting rod 17 to move.

[0035] The bottom of the limit rod 17 is slidably connected to the top of the fixed frame 13. When the moving columns 14 on both sides are squeezed to different degrees, the spring 2 15 will produce different degrees of reaction force on the moving column 14 due to its own elasticity, so that the moving column 14 maintains close contact with the shape of the product to fix the product. The top middle part of the cover plate 2 is rotatably connected with a card plate 18, and the bottom of the card plate 18 contacts the top of the bottom plate 1. The top front side of the bottom plate 1 is fixedly connected with a baffle 19. Then the card plate 18 is pulled backward out of the bottom of the baffle 19, and the top of the card plate 18 contacts the bottom of the baffle 19. Mounting grooves 20 are provided on both sides of the bottom plate 1 to complete the welding of the front and back sides. After that, the carrier is placed on the laser machine and installed using the mounting grooves 20, which is easy to flip and can adapt to products of different shapes. Wedge blocks and other sophisticated mechanisms are used to achieve synchronization of the cover and precise positioning, reducing employee operations.

[0036] Working principle: first place the bottom plate 1 to the appropriate position, then pull the card plate 18 backward out of the bottom of the baffle 19, and then place the product into the placement slot 10. When the product is placed into the placement slot 10, the outside will squeeze the block 8. At this time, rotate the bolt 9 according to the shape of the product. The position of the threaded column 4 can be moved under the rotation of the bolt 9. Adjust the threaded column 4 according to the degree of squeezing of the block 8 to move the position of the push block 6. At this time, the push block 6 will drive the limit block 7 to move. The position of the block 8 can be adjusted under the movement of the push block 6 and the limit block 7 to adapt to the shape of the product. Then place the products in the placement slots one by one. The outside of the second and third placement slots 11 and 12 is placed. At this time, the movable column 14 will be squeezed. Depending on the appearance of the product, the movable column 14 will be squeezed to varying degrees. At this time, the second spring 15 will be compressed. As the movable column 14 moves, the internal limit slot 16 will drive the limit rod 17 to move. When the movable columns 14 on both sides are squeezed to varying degrees, the second spring 15 will generate varying degrees of reaction force on the movable column 14 due to its own elasticity, so that the movable column 14 maintains close contact with the product's appearance, fixes the product, completes the welding of the front and back sides, and then places the carrier on the laser machine and installs it using the mounting slot 20 for easy flipping.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
