When drilling a small, thin part, it is easy to get driven by a rotating bit and cause an accident if the part is not pressed and held. Hold small parts, available graphical tools. In the picture, two earrings A with a round hole are welded on the right side of the channel, and an L-shaped pressing board is arranged between the two earrings. There is an adjusting screw hole in the lower part of the pressure plate, an adjusting screw B is arranged on the lower part of the pressure plate, a notch is formed on the upper part of the pressure plate, a slope shape is cut on both sides, and a through hole is arranged on the side of the middle part.
