[0024] Further as Figure 1 and Figure 3 illustrated, it is worth noting that the protection assembly 6 comprises an inner plate 61, the outer wall of one end of the inner plate 61 is fixedly connected with the outer wall of one end of the clamping plate 4, the outer wall of the other end of the inner plate 61 is fixedly connected with a vertical plate 62, two parallel sliding rods 63 are slidably arranged in one side of the vertical plate 62, the outer wall of one side of the sliding rod 63 is coaxially fixedly connected with a limiting plate 64, the outer wall of one side of the two sliding rods 63 arranged on the same vertical plate 62 is fixedly connected with the same outer plate 65, the outer surface of the sliding rod 63 is sleeved with a second spring 66, one side of the second spring 66 is fixedly connected with the outer wall of one side of the vertical plate 62, the other side of the second spring 66 is fixedly connected with the outer wall of one side of the outer plate 65.

[0025] Further as Figure 4 illustrated, it is worth noting that the bottom surface of the workbench 1 is fixedly connected with two fixed plates 7, the outer wall of one side of one of the fixed plates 7 is fixedly connected with a stepping motor 8, the output end of the stepping motor 8 is coaxially fixedly connected with a bidirectional threaded rod 9, the side of the bidirectional threaded rod 9 away from the stepping motor 8 is rotatably penetrated through one of the fixed plates 7 and rotatably connected with the outer wall of one side of the other fixed plate 7, the bidirectional threaded rod 9 is threadedly penetrated through the two moving plates 3.

[0030] When the two clamping plates 4 move close to each other, the two inner plates 61 move close to each other, and the two outer plates 65 move close to each other. When the two outer plates 65 move to the side wall and the side wall, the workbench 1 is in a closed state, achieving the protection effect. When the volume of the workpiece to be punched is small, the two outer plates 65 will continue to move after the side wall is in contact, thereby pushing the sliding rod 63 to slide on the vertical plate 62 and being buffered by the second spring 66. Until the two buffer plates 55 clamp and fix the workpiece, the protection effect is achieved under the cooperation of the inner plate 61 and the outer plate 65, effectively avoiding the problem that the worker's hand is easily injured by the flying debris during punching.
