The slide groove 5 is parallel to the front end side wall of the support frame 3, and two front wall plates 6 are slidably arranged in the slide groove 5. Handle grooves 7 are vertically opened on the front side end surfaces of the two front wall plates 6, and a rotating groove 8 is also opened on the front side end surfaces of the two front wall plates 6. The rotating groove 8 is a quarter arc groove, and the center of the arc-shaped rotating groove 8 coincides with the lower end of the handle groove 7. One end of the rotating groove 8 is connected to the upper end of the handle groove 7, and a handle 9 is rotatably connected to the lower end of the handle groove 7.

[0025] A threaded hole 10 is provided on the rear end side wall of the support frame 3 , a fixing hole 11 is penetrated through the rear wall plate 4 , a screw 12 is provided at the fixing hole 11 , and the screw 12 is threadably matched with the threaded hole 10 .

[0026] It should be noted that: when the raw material to be punched is placed inside the support frame 3 and is ready to be punched using the punching head and the cutting blade, the two front wall panels 6 are pushed toward the front end side wall of the support frame 3, so that the two front wall panels 6 are close to each other and close to each other. When the two front wall panels 6 are against each other, the handle 9 set in the handle groove 7 is rotated, and the other end of the handle 9 is rotated from one end of the rotating groove 8 to the other end, thereby completing the closing of the two front wall panels 6, and then blocking the front port of the support frame 3, and blocking the rear port of the support frame 3 by the rear wall panel 4.

[0027] The above arrangement is provided with a rear wall plate 4 on the rear end side wall of the support frame 3, and a slide groove 5 is provided on the upper end surface of the bottom plate 2. The slide groove 5 is parallel to the front end side wall of the support frame 3, and two front wall plates 6 are slidably provided in the slide groove 5. By closing the two front wall plates 6 and setting the rear wall plate 4, the front and rear ports of the support frame 3 are respectively blocked, and the flying debris during punching can be blocked, thereby reducing the probability of safety hazards. Furthermore, by setting the rotating groove 8 and the handle 9, when the two front wall plates 6 are against each other, the handle 9 is rotated, and by placing the handle 9 horizontally on the two front wall plates 6 at the same time, the abutting relationship between the two front wall plates 6 is reinforced, thereby improving the blocking effect of the front wall plates 6 on the materials, and further improving the safety of the device.

[0028] The rear wall plate 4 is fixed to the rear port of the support frame 3 by screws 12, so that the rear wall plate 4 can be easily loaded and unloaded, thereby improving the practicability of the device.
