Working principle:
1. The driving motor 401 rotates positively, the first electric push rod 402 moves downwards, the outer fixed teeth 501C are meshed with the outer gear ring 404B, the outer spiral cylinder 501 starts to rotate and drives the outer lifting sleeve 502 to move upwards, at the moment, the first clamping block 502D and the first lifting clamping tooth 604B are contacted with each other, the outer lifting rod cylinder 602 drives the mounting shell 601 to move upwards synchronously, so that the grabbing mechanism 3 performs rapid clamping action, the clamping claws 305 are rapidly close to and contact with the surface of goods, and the clamping force is gradually increased;
2. When the clamping force is higher than the preset value, the electric push rod I402 moves upwards, the inner fixed teeth 503C and the inner gear ring 404A are meshed with each other, the inner spiral cylinder 503 starts to rotate, the inner lifting sleeve 504 is driven to move upwards, the clamping block II 504A and the lifting clamping tooth II 605C are contacted with each other, the inner lifting rod cylinder 603 drives the mounting shell 601 to move upwards continuously, so that the grabbing mechanism 3 performs a slow clamping action, the clamping force of the clamping claws 305 on goods is slowly increased, and the grabbing operation of operators is easier and more free;
3. The second electric push rod 601B drives the reversing push plate 606 to complete one-time descending and ascending movement, the reversing pressure head 606B pushes the outer reversing swivel seat 604A to rotate 180 degrees, the reversing pressure head 606B pushes the inner reversing swivel seat 605A to rotate 90 degrees, at the moment, the descending latch 604C is contacted with the first clamping block 502D, the second clamping block 504A is contacted with the sliding surface 605B, and the mounting shell 601 rapidly moves downwards under the action of the elastic force of the pressure spring 7 to return to the initial position;
