[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This self-service checkout counter places merchandise on top of a first placement platform, causing the weight of the top of the first placement platform to change. At this time, the first placement platform sends an electrical signal to motor 1, thereby starting motor 1, which drives a threaded screw to rotate, thereby rotating the threads on the outer wall of the threaded screw. At this time, the threads on the outer wall of the threaded screw drive the second placement platform to move outward until the second placement platform is fully extended. When the first placement platform is idle, there is no item on top of the first placement platform, causing the second placement platform to retract against the inner wall of the support block. This ensures that the device does not occupy a large amount of space when idle, and people can still walk between devices.

[0013] 2. The self-service checkout counter pulls the support rod to move toward the inside of the fixed housing.

The outer wall of the lower extension block 13 is fixedly installed with a fixed shell 14. The inner wall of the fixed shell 14 is provided with a spring 15. The inner wall of the fixed shell 14 is slidably connected to the support rod 16. In the above structure, the weight sensing device 2 is electrically connected to the motor 16. When an object is placed on the top of the first placement table 3, the weight of the top of the first placement table 3 will change, thereby triggering the weight sensing device 2, so that the first placement table 3 controls the motor 16 to start.

[0023] In a preferred embodiment, an extension bar is provided at the bottom of the second placement table 5, and the extension bar is located at the bottom of the second placement table 5 on one side near the motor 16. The threaded screw 7 and the guide rail 8 pass through the extension bar at the bottom of the second placement table 5, and the threaded screw 7 is threadedly connected to the extension bar at the bottom of the second placement table 5. In the above structure, by starting the motor 16, the motor 16 drives the threaded screw 7 to rotate. When the threaded screw 7 rotates, the threaded connection between the threaded screw 7 and the extension bar at the bottom of the second placement table 5 drives the extension bar at the bottom of the second placement table 5 to move, and then drives the second placement table 5 to move. The second placement table 5 is limited by the guide rail 8, so that the second placement table 5 will not be offset during the movement.

[0024] In a preferred embodiment, rectangular grooves are provided on both sides of the outer wall of the second placement platform 5, and a rectangular block is provided on the inner wall of the support block 1 in the rectangular groove close to the outer wall of the second placement platform 5, and the rectangular block on the inner wall of the support block 1 is located in the rectangular groove on the outer wall of the second placement platform 5. In the above structure, the rectangular groove on the outer wall of the second placement platform 5 is limited by the rectangular block on the inner wall of the support block 1, thereby limiting the second placement platform 5, so that the second placement platform 5 cannot be separated from the support block 1.

[0025] In a preferred embodiment, the moving block 11, the telescopic inner strip 12, the lower extension block 13, the fixed sleeve 14, the spring 15 and the support rod 16 can be regarded as a flip assembly, and the number of the flip assemblies is two, and the two flip assemblies are located on both sides of the inner wall of the support block 1, and the two telescopic inner strips 12 are penetrated by the bidirectional screw rod 10, and the bidirectional screw rod 10 is threadedly connected to the telescopic inner strip 12. In the above structure, by pulling the support rod 16, the support rod 16 is allowed to enter the interior of the fixed sleeve 14. At this time, a gap is generated between the support rod 16 and the lower extension block 13, and the handholding part of the handbag is put on the outer wall of the support rod 16 through the gap, and the support rod 16 is released, so that the spring 15 rebounds and the support rod 16 is reset, so that the support rod 16 and the lower extension block 13 are re-sealed, and the handholding part of the handbag is fixed, and the two telescopic inner strips 12, the lower extension block 13, the fixed sleeve 14, the spring 15 and the support rod 16 are used to fix the handholding parts on both sides of the handbag.

[0026] In a preferred embodiment, the outer wall of the telescopic inner strip 12 is provided with a limit block, and the inner wall of the moving block 11 is provided with a limit groove. The extension block of the outer wall of the telescopic inner strip 12 is located in the limit block inside the moving block 11. In the above structure, the limit block of the outer wall of the telescopic inner strip 12 is limited by the extension limit groove inside the moving block 11, thereby preventing the telescopic inner strip 12 from being separated from the moving block 11.

[0027] In a preferred embodiment, the number of lower extension blocks 13 is two, and the two lower extension blocks 13 are symmetrically arranged at the bottom of the telescopic inner strip 12, and the length of the support rod 16 is greater than the distance between the two lower extension blocks 13. In the above structure, the two lower extension blocks 13 are closed by the support rod 16, so that the handle part of the plastic handbag is limited to the outer wall of the support rod 16.

[0028] Working principle: when using this device, place the goods on the top of the first placing table 3, so that the weight of the top of the first placing table 3 changes. At this time, the first placing table 3 sends an electrical signal to the motor 6, which starts the motor 6 and drives the screw rod 7 to rotate through the motor 6, thereby causing the thread on the outer wall of the screw rod 7 to rotate. At this time, the thread on the outer wall of the screw rod 7 drives the second placing table 5 to move outward until the second placing table 5 is fully extended. At this time, the goods are removed from the top of the first placing table 3, and the goods are scanned through the settlement module 4. The scanned goods are placed on the top of the second placing table 5. When the handbag needs to be opened, the support rod 16 is pulled to move the support rod 16. The handle of the handbag is inserted into the interior of the fixed sleeve 14. At this time, a gap is generated between the support rod 16 and the lower extension block 13. The handle of the handbag is put on the outer wall of the support rod 16 through the gap, and the support rod 16 is released, so that the spring 15 rebounds, resets the support rod 16, and the support rod 16 and the lower extension block 13 are re-sealed to fix the handle of the handbag. The handles on both sides of the handbag are fixed by two telescopic inner strips 12, the lower extension block 13, the fixed sleeve 14, the spring 15 and the support rod 16. At this time, motor 2 9 is started, and the bidirectional screw rod 10 is driven to rotate by motor 2 9, so that the two bidirectional screw rods 10 move to both sides, pulling the two handles of the plastic handbag to both sides, so that the plastic handbag is stretched open.
