The left surface of the bottom plate 1 is fixedly connected with a pull rod 3, and the pull rod 3 facilitates the movement of the device. The upper surface of the bottom plate 1 is fixedly connected with a support block 6. A through threaded hole is opened on the right surface of the support block 6. The upper surface of the bottom plate 1 is provided with product workpieces 4. There are multiple product workpieces 4, which are arranged neatly on the upper surface of the bottom plate 1. A clamping assembly is arranged above the bottom plate 1. The clamping assembly is used to clamp and fix the product workpieces 4. The clamping assembly includes a connecting block 52. A groove is opened on the upper surface of the bottom plate 1, so that the connecting block 52 can be stuck in the groove and slide smoothly. The right surface of the connecting block 52 is rotatably connected with a threaded rod 51. The left surface of the connecting block 52 is hinged with a positioning rod 514. When the connecting block 52 moves, it will squeeze the positioning rod 514, causing it to swing. The left surface of the positioning rod 514 is hinged with a clamping plate 56. The swinging positioning rod 514 will drive the clamping plate 56 to move horizontally. The front surface of the connecting block 52 is fixedly connected with a special-shaped rod 53. The left end of the rear surface of the special-shaped rod 53 penetrates and is rotatably connected with a second round rod 510. A buffer assembly is arranged above the bottom plate 1. The buffer assembly is used to avoid damaging the product workpieces 4 when pressing them. Two first-shaped slots 511 are opened on the front surface of the bottom plate 1, and they are symmetrically distributed on the front and rear surfaces of the bottom plate 1.

[0031] Refer to Figure 1 , Figure 2 , the clamping assembly further includes a second connecting rod 55. The second connecting rod 55 is a long strip-shaped rod. The right end of the rear surface of the second connecting rod 55 penetrates and is rotatably connected with a first round rod 59. A pressing block 57 is arranged on the rear surface of the second connecting rod 55. A first-shaped slot 58 is opened on the front surface of the pressing block 57. A sliding slot 512 is opened on the rear surface of the pressing block 57. The cross-section of the pressing block 57 is approximately U-shaped. A cover plate 513 is inserted into the inner wall of the sliding slot 512. The front surface of the pressing block 57 is hinged with a first connecting rod 54. The first connecting rod 54 is a long strip-shaped rod.

[0032] Refer to Figure 3 , the buffer assembly includes a sleeve 73. The sleeve 73 is an annular cylinder. The cover plate 513 is elastically connected with a movable rod 72 through a spring 74. The movable rod 72 is a cylindrical rod. A pressing plate 71 is fixedly connected to the lower surface of the movable rod 72. The lower surface of the pressing plate 71 is made of foam material, and the material is polyurethane foam. Polyurethane foam is a foam material mainly made of polyurethane, which has excellent cushioning performance, can effectively absorb impact energy, protect items from damage, and has good elasticity, and can quickly return to its original state after being stressed.

[0033] Refer to Figure 1, the rear surface of the clamping plate 56 is made of foam material, specifically polyurethane foam. Polyurethane foam is a foam material mainly made of polyurethane, which has excellent cushioning performance, can effectively absorb impact energy, protect items from damage, and has good elasticity. It can quickly return to its original shape after being stressed, avoiding damaging the product workpiece 4 when clamping the product workpiece 4. The round rod two 510 is slidably connected to the inner wall of the one-word groove two 511.

[0034] Refer to Figure 1 , Figure 2 , the clamping plate 56 is slidably connected to the upper surface of the bottom plate 1. The bottom plate 1 is also provided with a groove that allows the clamping plate 56 to slide smoothly. The round rod one 59 is slidably connected to the inner wall of the one-word groove one 58. The connecting rod one 54 rotates on the rear surface of the connecting rod two 55, making the connecting rod one 54 and the connecting rod two 55 form an X shape. The round rod two 510 passes through and is rotatably connected to the right end of the rear surface of the connecting rod one 54. The connecting rod two 55 is hinged to the front surface of the bottom plate 1. The threaded rod 51 passes through and is threadedly connected to the right surface of the support block 6. A handle for easy rotation is provided at the right end of the threaded rod 51. Rotating the handle can make the threaded rod 51 move left or right accordingly and drive the connecting block 52 to move synchronously.

[0035] Refer to Figure 3 , the sleeve 73 is fixedly connected to the lower surface of the cover plate 513. The movable rod 72 passes through and is slidably connected to the lower surface of the sleeve 73. There are four groups of sleeves 73, and the four groups of sleeves 73 are evenly distributed on the lower surface of the cover plate 513. One end of the spring 74 is fixedly connected to the lower surface of the cover plate 513, and the other end of the spring 74 is fixedly connected to the upper surface of the movable rod 72. When the movable rod 72 is compressed, it will squeeze the spring 74 and generate a reaction force.

[0036] Working principle: When using this device, stack multiple product workpieces 4 to be transported neatly on the bottom plate 1, insert the cover plate 513 into the sliding groove 512, and then rotate the handle of the threaded rod 51 to drive the threaded rod 51 to rotate and move to the right. The threaded rod 51 drives the connecting block 52 to move to the right synchronously. The connecting block 52 drives the two positioning rods 514 to move. The positioning rods 514 drive the two clamping plates 56 to move relatively and approach each other, thereby clamping the product workpiece 4. At the same time, the connecting block 52 will drive the special-shaped rod 53 to move to the right synchronously. The special-shaped rod 53 drives the round rod two 510 to move to the right along the one-word groove two 511. At the same time, the round rod two 510 will drive the right end of the connecting rod one 54 to move to the right. At the same time, the connecting rod one 54 will squeeze the connecting rod two 55, making the right end of the connecting rod two 55 and the round rod one 59 move to the right along the one-word groove one 58, and at the same time squeeze the pressing block 57 to make the pressing block 57 move downward. The pressing block 57 drives the cover plate 513 to move downward.

[0037] The cover plate 513 moves downward and drives the buffer assembly to move downward synchronously. When the pressing plate 71 touches the product workpiece 4 and cannot move downward continuously, at this time, the cover plate 513 continues to press downward for a certain distance, so that the spring 74 is compressed and generates a reaction force to press the product workpiece 4 tightly, and the spring 74 can prevent the product workpiece 4 from being damaged due to excessive pressure.

[0038] When it is necessary to remove the product workpiece 4, rotate the handle of the threaded rod 51 in the reverse direction, drive the connecting block 52 to move leftward. The connecting block 52 drives the positioning rod 514 to move. The positioning rod 514 drives the clamping plates 56 to move towards each other and release the product workpiece 4. At the same time, the connecting block 52 drives the special-shaped rod 53 to move leftward and push the first connecting rod 54, thereby causing the pressing block 57 to move upward, driving the cover plate 513 to move upward. The cover plate 513 drives the buffer assembly to move upward, releasing the pressing on the product workpiece 4. Then, the cover plate 513 and the buffer assembly are removed, so as to facilitate the worker to remove the product workpiece 4.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
