It should be noted that the pistol drill 1 is an existing mature technology, and the specific structure and working principle of the pistol drill 1 will not be described in detail here. Specifically, after pressing the power switch at the pistol drill 1, the drill chuck of the pistol drill 1 will rotate, and during the rotation, the helical gear shaft 2 will rotate, and a worm gear structure will be formed between the helical gear shaft 2 and the movable wheel 4. After the helical gear shaft 2 rotates, the movable wheel 4 will rotate. When in use, a thin plate is placed between the movable wheel 4 and the fixed wheel 7. During the rotation of the movable wheel 4, the thin plate will be sheared.

[0022] The specific steps of shearing the thin plate in the utility model are as follows:

[0023] Step S1: prepare tools and thin plate materials;

[0024] Step S2: Install the shear on the pistol drill 1 and perform fixed debugging;
