The working principle is as follows:

when in use, the pin ends of the potentiometers are placed on the support shafts 902 towards the forming groove 12, then the electric push rod 904 is started to push the push plate 905 to move, the push plate 905 pushes the potentiometers to move by taking the first sliding groove 906 as a path through the first sliding block 907, so that the potentiometers are pushed to move on the support shafts 902, the support shafts 902 rotate to convey the potentiometers until one ends of the potentiometers contact with the limiting blocks 903, the potentiometers are matched with the cutting knife 7, so that the lengths of the potentiometer pins of different types are the same, then the hydraulic cylinders 4 are started, so that the mounting plates 5 are pushed to move downwards, when the potentiometers move to a certain position, the connecting rods 6 are firstly connected with the second connecting holes 1404 through the first connecting holes 13, then the connecting rods are pressed downwards, so that the connecting rods 1403 and the screw rod sleeve 1402 are pushed to move downwards by taking the third guide rod 1405 as a path, and the reset springs 1406 are squeezed to generate resilience, the screw rod sleeve 1402 is matched with the screw rod 1401 to drive the screw rod 1401 to rotate, and drive the gear 1407 and the rack 1408 to rotate, so that the rack 1408 moves by taking the guide groove 15 as a path, and pushes the second slider 1102 and the mounting rack 1101 to move by taking the second chute 10 as a path, when moving, the cleaning strip 1109 can rotate in a circle shape with the rotating shaft 1108 and move upwards by taking the third chute 1104 as a path, when the output end of the hydraulic cylinder 4 moves to a certain position, the pressing plate 802 is firstly contacted with the main body of the potentiometer and presses the main body of the potentiometer through the elasticity of the first spring 803, then the cleaning mechanism 11 enters the groove formed on one side of the forming groove 12, meanwhile, the pressing strip 806 presses the pin of the potentiometer into the forming groove 12 through the elasticity of the second spring 805, and after pressing, the cutter 7 cuts off the overlong end of the pin, so as to finish the cutting of the pin, after the cutting is finished, the device is returned, after the pressure disappears, the driving mechanism 14 is pushed to return through the elastic force of the return spring 1406, the mounting rack 1101 is driven to move by taking the second sliding chute 10 as a path through the second sliding block 1102, the cleaning strip 1109 is enabled to clean the fragments inside the forming groove 12, the cleaning strip 1109 can move by taking the third sliding block 1105 and the third sliding chute 1104 as paths and stretch and contract through the elastic force of the third spring 1106, the inside of the forming groove 12 is cleaned in a stretching and contracting mode, after the cleaning is finished, the fragments are brought into the rectangular groove 16 through the cleaning strip 1109, and the fragments are leaked through the rectangular groove 16 to be recovered.
