[0086] In the initial state, the rotating plate 62 is separated from the pressure rod 48. First, people start the servo motor 3. The output shaft of the servo motor 3 drives the cam 65 to rotate through the rotating shaft 63. When the cam 65 contacts the rotating plate 62, the cam 65 drives the rear side of the rotating plate 62 to move downward, so that the front side of the rotating plate 62 moves upward. When the front side of the rotating plate 62 contacts the pressure rod 48, the rotating plate 62 drives the pressure rod 48 to move upward, and then the first connecting plate 41 and the electric drill 42 move upward. When the cam 65 is separated from the rotating plate 62, the front side of the rotating plate 62 moves downward due to gravity, so that the rear side of the rotating plate 62 moves upward, and then the front side of the rotating plate 62 is separated from the pressure rod 48, so that the pressure rod 48 is reset downward. Repeat the above steps. There is no need for people to manually pull the pressure rod 48, and the electric drill 42 can intermittently move downward to punch holes in the metal plate.

A second connecting rod 72 is slidably provided on the second connecting block 75. A limiting block 76 is provided on the rear side of the second connecting rod 72 3. A second spring 74 is provided between the limit block 73 and the second connecting block 75, a third connecting block 77 is provided on the front side of the guide plate 51, a fourth connecting plate 79 is provided on the front side of the second connecting rod 72, the third fixing assembly 78 is composed of a fixing rod and a fixing block, a fixing rod is rotatably provided on the fourth connecting plate 79, a fixing block is threadedly connected to the fixing rod, a push block 710 is provided on the fixing rod, a wedge plate 711 is slidably provided on the left side of the placement rack 52, the wedge plate 711 cooperates with the push block 710, a push plate 712 is provided on the right side of the wedge plate 711, the push plate 712 slides between the guide plate 51, the placement rack 52 and the third connecting plate 53, a guide rod 713 is slidably provided on the right side of the push plate 712, the guide rod 713 is connected to the third connecting block 77, a third spring 714 is provided between the push plate 712 and the third connecting block 77, and the third spring 714 is sleeved on the guide rod 713.

[0088] In the initial state, the push plate 712 is located at the front side of the guide plate 51. First, people place one end of the metal plate on the placement rack 52, and then people push the metal plate backward. When the metal plate contacts the push plate 712, the metal plate drives the push plate 712 to move backward, and the push plate 712 drives the wedge plate 711 to move backward. When the metal plate is pushed to a suitable position, the pushing of the metal plate can be stopped. At this time, the third spring 714 is deformed. When the convex circle 65 rotates, the convex circle 65 drives the connecting plate 70 to rotate through the first fixing component 71. The connecting plate 7 The second connecting block 75 is driven to rotate through the second fixing assembly 76, and the second connecting block 75 drives the fourth connecting plate 79 to move forward and backward through the second connecting rod 72. The fourth connecting plate 79 drives the push block 710 to move forward and backward through the third fixing assembly 78. When the push block 710 moves forward to contact the wedge plate 711, the push block 710 drives the wedge plate 711 to move forward. At the same time, the wedge plate 711 squeezes the push block 710, so that the second connecting rod 72 slides backward, the second spring 74 is deformed, and the wedge plate 711 drives the push plate 71 2 and the metal plate move forward, so that the unpunched part of the metal plate is located under the electric drill 42. When the push block 710 moves backward, the second spring 74 drives the second connecting rod 72 to reset, and the push block 710 does not drive the wedge plate 711 to move, so that the push plate 712 and the metal plate stop moving. At this time, the electric drill 42 punches the metal plate. By repeating the above steps, the metal plate can be moved forward in an orderly manner to the bottom of the electric drill 42 for punching. When the metal plate is punched, people can remove the metal plate. When the metal plate and the push plate 712 are separated, When the distance between the push block 710 and the wedge plate 711 is adjusted to the right, the fixing block on the first fixing assembly 71 can be reset to continue fixing the connecting disk 70 on the convex circle 65, so that the distance the metal plate is pushed can be adjusted, thereby adjusting the spacing of the punching holes.

[0089] It also includes a limiting mechanism 8, which includes a third connecting rod 80, a clamping block 81, a fourth spring 82, a fourth connecting block 83, a clamping plate 84 and a fifth spring 85.

When the card block 81 coincides with the bayonet, people stop rotating the card plate 84, and the fourth spring 82 drives the card block 81 to reset outward, so that the card block 81 enters the bayonet, so that the card plate 84 is fixed. Then people push the metal plate from front to back onto the placement rack 52. When the metal plate is placed, people pull the fourth connecting block 83 and the components thereon forward so that they are located on the front side of the metal plate. At this time, the fifth spring 85 is deformed. Then people can rotate the card plate 84 downward to reset it, so that the card plate 84 blocks the metal plate, which is convenient for the electric drill 42 to punch the metal plate. When the metal plate is punched and removed, the fifth spring 85 drives the fourth connecting block 83 to reset.
