When the drilling is completed, the handle is pulled, and the handle drives the limit rod to move, and the limit rod drives the fixing ring to move, at which time the reset spring is driven to extend, and then the limit rod is away from the limit hole. At this time, the receiving barrel can be pulled to remove it. When the debris is cleaned, just slide the mounting block outside the receiving barrel into the moving block, and then release the handle. At this time, the reset spring applies elastic force to the fixing ring to quickly reset it. At this time, the limit rod is stuck in the limit hole, thereby completing the rapid disassembly and installation of the docking barrel, so that the collected debris can be easily cleaned.

A moving block 405 is provided on the outer sleeve of the slide bar 403, and a pull-back spring 406 is provided on the outer sleeve of the slide bar 403. By setting the pull-back spring 406, during the drilling process, the pull-back spring 406 applies elastic force to the moving block 405, so that it always keeps in contact with the surface of the object being drilled. When the handle 51 is released, the pull-back spring 406 applies elastic force to the moving block 405, so that it can be quickly reset.
[0023] One end of the return spring 406 is connected to the connecting block 402, and the other end of the return spring 406 is connected to the moving block 405. The moving block 405 is slidably connected with a mounting block 407. The two mounting blocks 407 are connected to the same material receiving barrel 408. The material receiving barrel 408 is connected to a guide ring 409.

[0025] The working principle of the utility model is:
[0026] When drilling is required, align the drill bit 3 and the material receiving barrel 408 parallel to the position where the hole needs to be drilled. At this time, after the electric drill body 1 is started, the debris will slide into the material receiving barrel 408 through the guide ring 409. Then, when the drill bit 3 drills deeper, the return spring 406 applies elastic force to the moving block 405, so that the moving block 405 drives the mounting block 407 and the material receiving barrel 408 to always keep in contact with the object. When the drilling is completed, pull the handle 51, the handle 51 drives the limit rod 52 to move, and the limit rod 52 drives the fixing ring 53 moves, at which time the return spring 54 is extended, and then the limit rod 52 moves away from the limit hole 410. At this time, the material receiving barrel 408 can be pulled to be removed. When the debris is cleaned, just slide the mounting block 407 outside the material receiving barrel 408 into the moving block 405, and then release the handle 51. At this time, the return spring 54 applies elastic force to the fixing ring 53, so that it is quickly reset. At this time, the limit rod 52 is stuck in the limit hole 410, and the collection of debris and the rapid installation and removal of the material receiving barrel 408 are completed.
