an external power supply, the rotating motor 101 drives the collecting barrel 102 to rotate at the upper end of the bed body 1, so that the workpiece can move to the upper end of the collecting barrel 102, at the moment, the electric push rod 104 is connected with the external power supply, the electric push rod 104 drives the punching head 105 to move towards the workpiece and punch the workpiece from two sides, when the workpiece is not installed on the device, the first magnet 402 is attracted with the second magnet 406, at the moment, the limiting block 305 is inserted in the upper end position in the installation groove 301, when the workpiece is sleeved outside the cylinder 201, the workpiece can extrude the limiting block 305 when approaching the supporting seat 103, the limiting block 305 is extruded in the installation groove 301 to move downwards, because the half gear 404 is meshed with the second rack 403, so that the limiting block 305 moves downwards, the half gear 404 is driven to rotate, so that the second magnet 406 can rotate in the movable groove 405, at the moment, the second magnet 406 and the first magnet 402 repel each other, the first magnet 402 does not attract the second magnet 406 any more, the limiting block 305 moves downwards under the action of gravity, when the limiting block 305 moves to be out of contact with the clamping plate 304, under the action of the elastic force of the second spring 303, the clamping plate 304 is pushed to approach the outer surface of the sliding rod 302 towards the direction of the workpiece, so that circular pipe pieces with different diameters can be clamped, it should be noted that, because the second magnet 406 is in a cuboid shape, the second magnet 406 can contact with the first magnet 402 and press the first magnet 402 when rotating, after the second magnet 406 finishes rotating, the first magnet 402 is driven to reset under the action of the elastic force of the third spring 401, when the workpiece rotates to the lower end of the supporting seat 103, the limiting block 305 is close to the first magnet 402 under the action of elasticity, so that the workpiece is conveniently demoulded, the limiting block 305 and the clamping plate 304 can be reset, the next workpiece is conveniently clamped, under the cooperation of the electric push rod 104, when the stamping head 105 is close to the workpiece, the stamping head 105 drives the L-shaped plate 210 to synchronously move, the cylinder 201 is contacted with the first rack 207 and drives the first rack 207 to move, the first rack 207 is meshed with the first gear 206, so that the first gear 206 is driven to rotate, the return spring 209 is driven to deform, after the stamping is completed, the stamping head 105 starts to reset under the action of the electric push rod 104, at the moment, the first rack 207 loses the thrust of the L-shaped plate 210, under the action of the elasticity of the return spring 209, the return spring 209 drives the first gear 206 and the support barrel 208 to rotate, it should be noted that, the first gear 206 is connected with the cylinder 201 through a one-way bearing, when the supporting cylinder 208 rotates along with the movement of the first rack 207, the cylinder 201 does not rotate, when the supporting cylinder 208 rotates along with the return spring 209, the cylinder 201 starts to rotate, when the cylinder 201 rotates, the grinding roller 205 is driven to rotate, under the action of centrifugal force, the grinding roller 205 pulls the supporting frame 202 and the supporting rod 203 to move away from the cylinder 201, so that the length of the supporting rod 203 inserted inside the cylinder 201 can be reduced according to the diameter of a workpiece, thereby grinding the inner walls of circular tubes with different diameters, when the cylinder 201 stops rotating, the grinding roller 205 resets under the elastic force of the first spring 204, when the supporting cylinder 208 rotates reversely, the threaded pipe 501 and the piston 502 are driven to slide downwards inside the supporting cylinder 208, the air pressure in the supporting cylinder 208 at the upper end of the piston 502 is reduced, the air outside the supporting cylinder 208 can be pumped into the supporting cylinder 208 from the upper end of the supporting cylinder 208, because the upper end of the supporting cylinder 208 is provided with a through groove at the position flush with the supporting seat 103, waste scraps generated by grinding the interior of a workpiece can drop on the supporting seat 103, the air in the interior of the workpiece can be extracted by the piston 502 when the piston 502 moves, the waste scraps dropping on the upper end of the supporting cylinder 208 can be sucked into the cylinder 201, the waste scraps can drop on the upper end of the piston 502, meanwhile, when the piston 502 moves downwards, the air at the lower end of the piston 502 can be extruded, the air at the lower end of the piston 502 can be exhausted from the hose 504 through the air cylinder 503, when the air is exhausted, the air drives the fan 505 to rotate so as to drive the grinding roller 205 to rotate, when the piston 502 moves to the lower end of the supporting cylinder 208 without being contacted with the air cylinder 503, at the moment, the scraps on the piston 502 can slide down to the inside of the supporting seat 103 from the middle of the piston 502, when a workpiece is ground, the baffle 602 extrudes the four-spring 603 to slide downwards on the outer surface of the fixing rod 601 under the action of gravity, at the moment, the baffle 602 is not contacted with the supporting cylinder 208, under the cooperation of the scrap sucking mechanism 5, the collected scraps can fall to the inside of the collecting barrel 102 through the supporting cylinder 208, when the workpiece rotates to the side along with the collecting barrel 102, the baffle 602 can be pushed to be contacted with the supporting cylinder 208 under the action of the elastic force of the four-spring 603, so that the scraps in the collecting barrel 102 can not enter the inside of the supporting cylinder 208, when the workpiece moves to the lowest end along with the collecting barrel 102, at the moment, under the action of gravity, the baffle 602 still contacts with the supporting cylinder 208, so that the scraps can not fall into the inside of the supporting cylinder 208, under the cooperation of the clamping mechanism 3 and the adjusting mechanism 4, when the limiting block 305 moves towards the direction of the grinding roller 205 under the action of gravity, the limiting block 305 can push the punched workpiece to be demolded, and the demolded workpiece
