The working principle of the invention is as follows:
the driving part 1 adopted by the invention is a motor, and is externally connected with a power supply and a control switch when in use. Firstly, the metal plate 22 to be punched is put into the first limiting groove 23 in parallel through the second limiting groove 25, and the metal plate 22 is supported through the first limiting groove 23 and the second limiting groove 25. When the driving piece 1 is not started, the eccentric piece 6 does not rotate, the rotating piece 12 does not rotate, and at the moment, the gear teeth 13-1 of the half gear 13 are meshed with the gear 14; when the driving part 1 is started, the driving part 1 drives the eccentric part 6 to rotate, the eccentric part 6 drives the rotating part 12 to rotate, the rotating part 12 drives the half gear 13 to rotate, at this time, the half gear 13 and the gear 14 are in a meshed state, the rotation of the half gear 13 can drive the gear 14 to rotate, the gear 14 rotates to drive the rack 15 meshed with the gear 14 to move, the top of the rack 15 is fixedly connected with the transverse moving plate 21, the transverse moving plate 21 and the rack 15 move synchronously, the transverse moving of the transverse moving plate 21 drives the transverse moving of the second fixing plate 11 connected with the transverse moving plate 21, the transverse moving of the second fixing plate 11 enables the metal plate 22 in contact with the first limiting groove 23 to move transversely under the driving of friction force, so that when the driving part 1 is started, the rotating angle of the eccentric part 6 is 0 to 90 degrees, the metal plate 22 moves, but at this time, the contact point of the eccentric part 6 and the pulley 7-1 does not reach the lowest point, and at this time, the rotation of the eccentric part 6 does not enable the punch 20 to punch the metal plate 22; when the eccentric member 6 rotates 90 degrees, at this time, because the gear teeth 13-1 of the half gear 13 occupy one fourth of the surface area of the outer ring of the half gear 13, and when the eccentric member 6 rotates 90 degrees, the half gear 13 rotates one quarter of a circle, the gear teeth 13-1 of the half gear 13 are not meshed with the gear 14, at this time, the lateral moving plate 21 stops lateral movement, the metal plate 22 also stops lateral movement, because the eccentric member 6 rotates 90 degrees, the end with larger radian of the eccentric member 6 extrudes the limiting plate 8 on one side, so that the limiting plate 8 longitudinally moves, and the second spring 2-2-1 is extruded by the second slider 8-1 while the limiting plate 8 longitudinally moves, the longitudinal moving plate 9 is driven by the longitudinal moving of the limiting plate 8 to longitudinally move, because of the characteristic that the longitudinal moving plate 9 is movably connected with the first supporting plate 3, therefore, the longitudinal moving plate 9 can longitudinally move on the upper surface of the first support plate 3, the longitudinal moving of the longitudinal moving plate 9 drives the metal plate 22 in the first limit groove 23 to longitudinally move, the pulley 7-1 slides to the lowest point of the eccentric part 6 while the eccentric part 6 rotates, and when the eccentric part 6 rotates by 90 degrees, the contact point of the pulley 7-1 and the eccentric part 6 is the lowest point, so that the punch 20 punches the metal plate 22 by the rotation of the eccentric part 6, and meanwhile, the transverse moving plate 21 cannot longitudinally move due to the limit of the transverse moving plate 21 by the first spring 24, so that the collision of the rack 15 to the gear 14 can be avoided, when the eccentric part 6 rotates by 90 degrees, the metal plate 22 longitudinally moves, and the punch 20 punches the metal plate 22; when the eccentric part 6 rotates 180 degrees, the gear teeth 13-1 of the half gear 13 are not meshed with the gear 14, so that the metal plate 22 cannot move transversely, the connecting rod 17 is driven by the rotation of the eccentric part 6 to drive the T-shaped sliding block 18 to move upwards in the T-shaped sliding groove 2-1, so as to drive the punching arm 19 to move upwards, punching does not occur at the moment, meanwhile, when the eccentric part 6 rotates 90 degrees, the second sliding block 8-1 extrudes the second spring 2-2-1, and when the eccentric part 6 rotates 180 degrees, the eccentric part 6 does not have extrusion force on the limiting plate 8, so that the second spring 2-2-1 generates resetting force on the second sliding block 8-1, and the second sliding block 8-1 drives the limiting plate 8 and the longitudinal moving plate 9 to reset; when the eccentric part 6 rotates 270 degrees, the gear teeth 13-1 of the half gear 13 are not meshed with the gear 14, the eccentric part 6 extrudes the limit plate 8, the motion track of the limit plate 8 is opposite to the direction when the eccentric part 6 rotates 90 degrees, and similarly, the longitudinal moving plate 9 also moves in the opposite direction to drive the metal plate 22 to move in the opposite direction, and the contact point of the pulley 7-1 and the eccentric part 6 is the lowest point at the moment, so that the punch 20 punches the metal plate 22 by the rotation of the eccentric part 6, when the eccentric part 6 rotates 270 degrees, the metal plate 22 longitudinally moves in the opposite direction to the direction when the eccentric part 6 rotates 90 degrees, and the punch 20 punches the metal plate 22; when the eccentric part 6 rotates by 270 degrees to 360 degrees, the gear teeth 13-1 of the half gear 13 are meshed with the gear 14 at the moment, and the driving gear 14 rotates, so that the rack 15 is driven to move transversely, and the metal plate 22 moves transversely, and meanwhile, the extrusion force of the eccentric part 6 on the limiting plate 8 is gradually weakened, so that the reset force of the first spring 24 on the limiting plate 8 is gradually strengthened, and the metal plate 22 is driven to reset gradually to the initial position; when the eccentric member 6 is rotated by 360 deg., the eccentric member 6 is restored to the original state, and the teeth 13-1 of the half gear 13 are engaged with the gear 14.
