[0030] The transport mechanism 8 also includes an extrusion plate 808, and two extrusion plates 808 are fixedly connected to the outer walls of the partition 807 on both sides. The two extrusion plates 808 are symmetrically distributed with the middle of the partition 807 as the center, and the side of the extrusion plate 808 away from the partition 807 is set in a semicircle, so that the extrusion plate 808 can stably clamp the metal.

[0031] When in use, the filter plate 7 on the support platform 4 is rotated downward to fix and cover the discharge port 5, and the metal opening is sent upward to the upper side of the support platform 4 through the feeding device.

[0034] When the drilling machine 3 is lowered to drill holes, the fixed pipe 904 is driven to descend, so that the fixed pipe 904 extends the rubber head 905 into the metal that has been drilled. At this time, the fan 901 is started, and the fan 901 extracts the metal and the punching debris remaining on the upper side of the extrusion plate 808 through the exhaust pipe 902, the fixed pipe 904, and the rubber head 905, and the debris is discharged into the internal cavity of the support platform 4 through the exhaust pipe 906.

[0035] Embodiment three:

[0036] See also Figure 1-Figure 5 On the basis of the second embodiment, the present invention provides a technical solution: the scraping mechanism 907 includes a threaded tube 701, the upper end of the threaded tube 701 is threadedly connected to the inner wall of the fixed tube 904, and the lower end of the threaded tube 701 extends to the lower side of the rubber head 905, the lower end of the threaded tube 701 is fixedly connected with a friction head 703, the upper side of the friction head 703 is rotatably connected with a spring 702 through a bearing, the upper end of the spring 702 is fixedly connected to the upper side of the inner wall of the rubber head 905, the side wall of the friction head 703 is fixedly connected with a scraper 704, the lower side wall of the threaded tube 701 is provided with an opening, the interior of the fixed tube 904 is connected to the lower side of the rubber head 905 through the threaded tube 701 and the opening on the threaded tube 701, the lower side height of the scraper 704 is consistent with the lower side height of the friction head 703, and the diameter of the friction head 703 is larger than the diameter of the lower output end of the drilling rig 3;

[0037] After the punching is completed, when the metal receiving rubber head 905 absorbs the punching debris, the rubber head 905 will extend into the inside of the metal, so that the friction head 703 will first contact the bottom of the metal. Since the hole punched in the metal is smaller than the friction head 703, the friction head 703 will be blocked by the metal. As the fixed tube 904 continues to descend, the threaded tube 701 will retract into the inside of the fixed tube 904.
