After moving it to the appropriate position, tighten the fastening bolt 904 so that the end of the fastening bolt 904 is tightly fitted with the surface of the fixed block 21, so that the position of the protective frame 901 can be fixed. When the workpiece is processed, metal debris generated when the drill bit 8 contacts the metal workpiece will splash everywhere. The protective frame 901 can block the debris, so that the debris will fall on the top of the operating table 3 and the inner wall of the protective frame 901. Start the electric telescopic rod 10, and the electric telescopic rod 10 drives the push plate 11 to move to the right. When the push plate 11 moves, it will push the waste debris on the top of the operating table 3 and the inner wall of the protective frame 901 to move, so that the waste debris will fall through the through hole 13 into the pull-out box 16 inside the collection frame 14. When there is a lot of debris collected in the pull-out box 16, pull the handle 20 to take out the pull-out box 16, and then the debris can be processed centrally.
