The motor body 3 is arranged inside the bidirectional screw rod 2 which passes through the first mounting frame 1, and the first movable ring 4 and the second movable ring 5 are arranged on the outer surface of the bidirectional screw rod 2 from left to right in sequence. The bottom end of the second movable ring 5 is fixedly connected with the second connecting block 13, and the bottom end of the second connecting block 13 is fixedly connected with the second clamping plate 14. The second clamping plate 14 has the same size as the first clamping plate 7. The bottom end of the first movable ring 4 is fixedly connected with the first connecting block 6, and the bottom end of the first connecting block 6 is fixedly connected with the first clamping plate 7. When the product is subjected to the indentation operation, the first clamping plate 7 and the second clamping plate 14 are firstly moved away from the side of the product, and then the output shaft is driven to rotate by the forward and reverse motor 22, thereby driving the rotating cylinder 17 to rotate, and the forward and reverse motor 22 can perform forward and reverse rotation. After the rotating cylinder 17 rotates, it drives the protrusion 19 to move inside the groove 18, so that the telescopic cylinder 20 will move forward, thereby driving the contact plate 21 to contact the product, and the product is quickly unloaded;

The design of the buffer pad 8 reduces damage to the product during clamping. At the same time, after the left and right sides of the product are clamped and stabilized, the electric push rod 10 is started, and the electric push rod 10 starts to move downward, thereby driving the resistance pad 11 to fit the top surface of the product for clamping. When the product is indented, first, the first clamping plate 7 and the second clamping plate 14 are moved away from the side of the product, and then the output shaft is driven to rotate by the forward and reverse motor 22, thereby driving the rotating cylinder 17 to rotate, and the forward and reverse motor 22 can rotate forward and reverse. After the rotating cylinder 17 rotates, it drives the protrusion 19 to move inside the groove 18, so that the telescopic cylinder 20 will move forward, thereby driving the resistance plate 21 to contact the product, and the product is quickly unloaded. The above is the entire working principle of the utility model.
