The working principle is as follows: when in compression joint, firstly, the metal sleeve penetrates through the positioning device 6, then two wires are respectively inserted at two ends of the metal sleeve, the air filling switch of the air pump 2 is opened, the air pump outputs air and the air enters the air flow channel 32 and the air flow channel 33 through the air filling pipe 4, under the action of air pressure in the air flow channel 32 and the air flow channel 33, the compression joint 34 moves towards the metal sleeve and applies pressure to the briefly described sleeve so as to realize compression joint operation on the metal sleeve and the two wires, after the compression joint is finished, the air suction switch of the air pump 2 is opened, the air pump 2 pumps out air in the air flow channel 32 and the air flow channel 33 through the air filling pipe 4, at the moment, the compression joint 34 resets under the action of negative pressure and is separated from the metal sleeve, and the wires and the metal sleeve are taken out; when the crimping head 34 moves for crimping, the two telescopic connecting rods 51 are driven to rotate, the two hinged transmission rods 52 are pushed by the telescopic connecting rods 51 to rotate, and the limiting column bars 53 can move towards the metal sleeve by the rotation of the two hinged transmission rods 52, so that the outer wall of the metal sleeve is limited, and the part of the metal sleeve, which is positioned at the two crimping heads 34, is prevented from protruding outwards and deforming;

when the metal sleeve penetrates through the positioning device 6, the metal sleeve can push the positioning block 72 to rotate, the limiting plate 73 is separated from the mounting block 71 at the moment, after the metal sleeve is separated from the positioning block 72, the positioning block 72 resets under the action of gravity, the limiting plate 73 is contacted with the mounting block 71 again, at the moment, the two positioning blocks 72 cannot rotate reversely under the limiting action of the limiting plate 73, the moving range of the metal sleeve can be limited, the phenomenon that the moving range of the metal sleeve is too large to influence the crimping effect when a lead is inserted is prevented, after the crimping is finished, the height of the metal sleeve is reduced because the top and the bottom of the metal sleeve are both extruded, the metal sleeve is not blocked by the positioning block 72 any more, and the metal sleeve can be directly taken out;

when the air pump 2 inflates air, the air pressure in the driving channel 411 is increased, the sliding piston 412 descends under the action of the air pressure and enables the L-shaped rod 8 to drive the control rod 9 to move towards the direction away from the positioning device 6 under the arc guiding action of the driving channel 411, at the moment, the clamping groove can firstly push the arc jacking plate 101 to ascend through the arc driving plate 102, when the control rod 9 is separated from the arc driving plate 102, the arc driving plate 102 and the arc jacking plate 101 can reset under the action of gravity, and the air pump is in an air inflation state in the ascending process of the arc jacking plate 101, so that the bottommost crimping head 34 can jack the metal sleeve, the arc jacking plate 101 cannot be in contact with the metal sleeve, when the air pump 2 evacuates air after crimping is completed, the sliding piston 412 resets under the action of negative pressure, the corresponding L-shaped rod 8 and the control rod 9 also reset, the end point of the control rod 9 away from the L-shaped rod 8 can push the arc jacking plate 101 to jack upwards through the arc driving plate 102, since the friction force between the sliding piston 412 and the driving channel 411 is greater than the friction force between the crimping head 34 and the pneumatic channel 33, the moving speed of the sliding piston 412 is less than that of the crimping head 34, and the sliding piston 412 is used for jacking up the metal sleeve, so that the metal sleeve is separated from the crimping head 34;

when the air pump 2 bleeds, the crimping head 34 resets, the movable rod 11 removes towards positioner 6 inner wall under the effect of restriction post strip 53, the form department of cutting of triangular groove 112 can produce the striking with rubber hemisphere piece 611 this moment, thereby produce the vibration, this vibration passes through vibrating arm 61 and positioner 6 and transmits to arc jacking plate 101 on, in order to improve metal sleeve's the effect that breaks away from at arc jacking plate 101 jack-up metal sleeve, striking strip 1012 also can vibrate and strike arc jacking plate 101 under the effect of arc jacking plate 101 vibration and inertia when arc jacking plate 101 vibrates simultaneously, in order to realize the multiple vibration of arc jacking plate 101.
