[0027] Among them, the bottom end of the installation door connection electric drill 1 is fixedly connected with a first connecting sleeve 10, the inner side of the first connecting sleeve 10 is connected with a connecting threaded sleeve 11 through threaded transmission, the bottom end of the connecting threaded sleeve 11 is fixedly connected with an auxiliary handle 12, and the top end of the installation door connection electric drill 1 is fixedly connected with a second connecting sleeve 5.

[0028] The auxiliary handle 12 can facilitate the operator to use the installation door to connect the electric drill 1. At the same time, when the auxiliary handle 12 is not in use, the position of the auxiliary handle 12 can be limited to the inner side of the second connecting sleeve 5, thereby providing good protection for the auxiliary handle 12.

[0029] Among them, there are multiple elastic springs 4, and multiple limit components 7 are distributed in a ring array on the inner side of the elastic shell 3. There are multiple limit components 7, and multiple limit components 7 are distributed in a ring array on the outer side of the elastic ring plate 6.

[0030] A plurality of elastic springs 4 can improve the pushing effect of the limiting sleeve 8 .

[0031] Among them, the limiting assembly 7 includes a limiting block 71 fixedly connected to the elastic annular plate 6, a limiting hole 72 is opened on the outer side of the elastic shell 3, the outer side of the limiting block 71 is slidably connected to the inner side of the limiting hole 72, and the limiting block 71 is T-shaped.

[0032] The limiting assembly 7 can limit the movement of the elastic annular plate 6, thereby effectively preventing the elastic annular plate 6 from being displaced during the movement.

[0036] Working principle:

[0037] When the door needs to be installed, after marking the position where the hole needs to be drilled, the drilling drill bit 2 on the outside of the electric drill 1 is aligned with the mark, and then the drilling operation is performed. During the drilling process, the debris will be restricted by the protective sleeve 93, so that the debris will not splash on the protective sleeve 93. At the same time, the protective sleeve 93 can block the debris as the drilling drill bit 2 is inserted, thereby improving the overall use effect;

[0038] When the drilling drill bit 2 needs to be disassembled and replaced, the protective sleeve 93 can be removed by rotating the protective sleeve 93, thereby increasing the space and facilitating the replacement operation of the drilling drill bit 2.
