A slide groove is opened inside the pressure plate 13, and an anti-splash component 3 is arranged in the slide groove. When the bottom of the pressure plate 13 fits the surface of the workpiece, the anti-splash component 3 pops out to form a closed retaining ring. By arranging the pressure plate 13 on both sides of the electric drill rod 12, the first elastic member 23 applies a reaction force to the pressure plate 13 during drilling, so that the bottom of the pressure plate 13 presses the periphery of the drilling position, thereby reducing the vibration generated when drilling the surface of the profile and improving the accuracy of the drilling hole diameter.

[0032] The shock absorbing assembly 2 includes a slide bar 21 arranged on both sides of the electric drill rod 12, a slide column 22 is arranged under the slide bar 21, the slide bar 21 slides on the inner wall of the slide column 22, a pressure plate 13 is arranged at the bottom of the slide column 22, and a first elastic member 23 is arranged between the pressure plate 13 and the electric drill rod 12. When drilling, the movable arm 11 drives the electric drill rod 12 to move vertically downward. During the movement, the pressure plate 13 first fits with the surface of the aluminum material. After the bottom of the pressure plate 13 is blocked, it pushes the slide column 22 to slide on the surface of the slide bar 21. At the same time, the first elastic member 23 is squeezed and deformed by force to form a reaction force on the pressure plate 13, so that the pressure plate 13 presses on both sides of the aluminum hole, thereby increasing the stability of the drilling hole, thereby reducing the vibration of the aluminum surface and improving the accuracy of the drilling hole diameter.

[0033] During use, the movable arm 11 is used to drive the electric drill rod 12 to move vertically downward. During the movement, the pressure plate 13 first fits against the surface of the aluminum material. After the bottom of the pressure plate 13 is blocked, it pushes the sliding column 22 to slide on the surface of the sliding rod 21.
