When the eccentric shaft 33 and the swing arm 35 movably connected at one end of the rotating shaft 32 move along the central axis of the rotating shaft 32 under the driving of the driving assembly 2, the eccentric shaft 33 squeezes the pull rope 34 to drive the connecting bar 381 connected to the pull rope 34 to move, and the connecting bar 381 is directional movement through the rack rod 387 fixedly connected by the pull rod 382. At this time, the rack rod 387 is meshed with the toothed ring groove 37 provided in the connecting rod 36, so that the rack rod 387 drives the connecting rod 36 to rotate along the central axis of the connection of the swing arm 35. , the clamping assembly 4 fixedly connected at one end of the connecting rod 36 is flipped, which is convenient for grinding and cutting the dead angle position of the metal plate 6, reducing the influence of the dead angle residue of the cutting of the metal plate 6. When the air pump 22 in the driving assembly 2 drives the push block 24 to reset, the sliding block 26 is elastically acted on the connecting rod 36 connected by the connecting strip 381 under the elastic action of the reset spring 27, so that the swing mechanism 3 is reset, and the eccentric shaft 33 fixedly connected to the swing arm 35 relaxes the tension of the pull rope 34, so that the elastic spring 384 fixedly connected at one end of the clamping block 386 resets the rack rod 387 to the clamping assembly 4, thereby improving the convenience of the device when used, and the device is flexible to use, which is worthy of wide promotion;

[0045] The clamping assembly 4 includes a limiting column 41, one end of which is provided with a threaded bolt 42, the top of which is fixedly connected to a nut cap 43, one end of which is connected to a movable block 44, and the bottom end of which is fixedly connected to a positioning block 47, one end of which is movably connected to the threaded bolt 42, and the threaded bolt 42 is threadedly connected to the movable block 44; one end of the movable block 44 is fixedly connected to a connecting frame 1 45, and a clamping wheel 1 46 is symmetrically arranged in the connecting frame; one end of the positioning block 47 is fixedly connected to a connecting frame 2 49, and a nut cap 43 is fixedly arranged in the top of the threaded bolt 42 ...

[0046] Specifically, the threaded bolt 42 at one end of the limiting column 41 is rotated so that the movable block 44 threadedly connected on the threaded bolt 42 drives the connecting frame 1 45 to move, so that the distance between the clamping wheel 1 46 movably connected on the connecting frame 1 45 and the clamping wheel 2 48 movably connected to the connecting frame 2 49 in the positioning block 47 is adjusted, so that the clamping assembly 4 can clamp the metal plates 6 of different sizes and thicknesses.

When the push block 24 in the driving component 2 pushes the locking block 56 to the limit sleeve 25, the limit sleeve 25 limits the position of the support plate 51 connected to the locking block 56, so that the locking block 56 abuts against the limit sleeve 25 under the action of the push block 24 and then moves along the directional rod 54, so that the push block 24 continues to drive the sliding block 26 at one end to move, which is convenient for the swing mechanism 3 to move. The push block 24 drives the support plate 51 connected to the locking block 56 to reset during the reset stroke, and then the cut metal plate 6 is manually taken. The structure is simple and easy to use.

In the first stroke, the driving assembly 2 pushes the metal plate 6 on the feeding assembly 5 along the direction of the clamping assembly 4, so that the metal plate 6 contacts and cuts with the cutting blade 7. When the feeding assembly 5 sends the metal plate 6 to the limiting sleeve 25, it separates from the driving assembly 2 and stops, and the metal plate 6 is cut to a preset position. In the second stroke, after the feeding assembly 5 is separated from the driving assembly 2, the swing mechanism 3 is pushed to make a circular motion along the central axis of the cutting blade 7 through the connecting arm 361. When the swing mechanism 3 moves, the linkage assembly 38 arranged on the swing mechanism 3 flips the clamping assembly 4 connected to the swing assembly in a passive manner, so that the metal plate 6 clamped in the clamping assembly 4 rotates along the axis of the connection between the clamping assembly 4 and the swing mechanism 3, so as to facilitate the cutting and grinding of the cut edge of the cut metal plate 6, reduce the cutting dead angle remaining in the groove of the cut metal plate 6, and avoid tearing of the metal plate 6 in the subsequent bending process.
