when the punching head 4a needs to be pulled out of the plastic tube 5 after the punching is completed, in the process of pressing the punching head 4a downward, the outer surface edge of the punching part of the plastic tube 5 is extruded once, so that the outer surface edge of the punching part of the plastic tube 5 becomes more easily deformed, that is, when the punching head 4a is pulled out outward, the outer surface edge of the punching part of the plastic tube 5 is pulled upward and is more easily deformed, therefore, after being stressed, the outer surface edge of the punching part of the plastic tube 5 is deformed by being rolled outward, in order to prevent the deformation, in the process of pressing the punching head 4a downward to complete the punching, the third connecting frame 404 is simultaneously driven to move downward, then the third connecting frame 401404 drives the two connecting rods 4012 to move downward, that is, the two connecting rods 4012 drive the two V-shaped hooks 3 to slide downward in the two limiting rails 4015, and the upper ends of the two V-shaped hooks 4013 are separated from the inclined opening formed on the limit plate 4014, when the L-shaped hooks arranged at the lower sides of the two V-shaped hooks 4013 contact the round heads at the upper ends of the convex columns 4018, because the diameter of the round heads at the upper ends of the convex columns 4018 is larger than the distance between the two L-shaped hooks at the lower sides of the two V-shaped hooks 4013, the round heads at the upper ends of the convex columns 4018 simultaneously press the two V-shaped hooks 4013, so that the two V-shaped hooks 4013 rotate around the two connecting rods 4012, when the reference is seen from right to left, namely the V-shaped hook 4013 at the front rotates clockwise around the connecting rod 4012 at the front, the V-shaped hook 4013 at the rear rotates anticlockwise around the connecting rod 4012 at the rear, when the third elastic piece 4017 between the two V-shaped hooks 4013 is compressed, the distance between the two L-shaped hooks at the lower sides of the two V-shaped hooks 4013 is increased, and the convex columns 4018 can smoothly pass through the convex columns 4018, after the upper end round head of the convex column 4018 is passed, the extrusion of the upper end round head of the convex column 4018 is lost, the two V-shaped hooks 4013 restore to a relatively normal state again under the action of the resilience force of the third elastic piece 4017, at the moment, the stamping head 4a is also stamped and finished, the plastic pipe 5 needs to be drawn out, when the stamping head 4a is drawn out upwards, the third connecting frame 404 is driven to move upwards, and then the two V-shaped hooks 4013 move upwards, because the diameter of a cylinder at the lower side of the round head of the convex column 4018 is smaller than the distance between the two L-shaped hooks, when the L-shaped hooks of the two V-shaped hooks 4013 are contacted with the round head of the convex column 4018, the round head of the convex column 4018 can be hooked, and the convex column 4018 is driven to move upwards synchronously, and then the second connecting plate 4016 is driven to slide upwards in the two limit rails 4015 through the convex column 4018, namely, the rack 4019 is driven to move upwards, and then the flat gear 4021 is driven to rotate through the rack 4019, based on the front-to-back view, the flat gear 4021 rotates clockwise, then the flat gear 4021 drives the second bevel gear 4022 through the second transmission shaft 4020, drives the first bevel gear 4011 through the second bevel gear 4022, drives the first transmission shaft 409 to rotate through the first bevel gear 4011, drives the second transmission wheel 4010 to rotate through the first transmission shaft 409, drives the first transmission wheel 408 to rotate through the second transmission wheel 4010, and further drives the screw rod 405 to rotate through the first transmission wheel 408, so that the screw rod 405 drives the first connection plate 406 to move downwards, that is, the first connection plate 406 drives the extrusion frame 407 to move downwards, when the stamping head 4a is drawn out, the extrusion frame 407 applies a downward pressure to the outer surface edge of the punching part of the plastic tube 5, and further forms a reaction force to the upward tension on the outer surface edge of the punching part of the plastic tube 5 when the stamping head 4a is drawn out, and the two forces are mutually offset, when the punching head 4a is further prevented from being drawn out, the outer surface edge of the punched part of the plastic tube 5 is prevented from being deformed by outward rolling, after the upper ends of the two V-shaped hooks 4013 rise to be contacted with the inclined opening of the limiting plate 4014 again, under the action of the inclined opening of the limiting plate 4014, the two L-shaped hooks on the lower sides of the two V-shaped hooks 4013 are opened, namely, the distance between the two L-shaped hooks is increased and is larger than the diameter of the round head on the convex column 4018, so that the second connecting plate 4016, the convex column 4018 and the rack 4019 slide to the initial position again under the action of gravity, the rack 4019 descends, and meanwhile, the flat gear 4021 rotates anticlockwise, so that the extrusion frame 407 returns to the normal state, namely, no pressure is applied to the outer surface edge of the punched part of the plastic tube 5, and meanwhile, the two V-shaped hooks 4013 return to the initial state again under the action of the resilience force of the third elastic piece 4017;
