When the drilling machine 8 moves downward and the output end is rotated by turning on the motor 81 to perform drilling, the two slide bars 11 support the surface of the workpiece so that the drill bit can only penetrate into the workpiece by the distance of the end of the slide bar 11. When the workpiece deviates to one side, the pressure plate 2 is pushed so that the slide bar 11 slides inside the slide groove 21 through the slider 22, so that the pressure plate 2 is moved toward the workpiece. When the slide bar 11 moves downward, the press plate 2 contacts the workpiece surface and presses the workpiece. When the press plate 2 moves downward with the slide bar 11 to press the workpiece, it first contacts the workpiece surface through multiple elastic rods 32.

When the slide bar 11 moves downward, the press plate 2 contacts the workpiece. When moving, the bottoms of the two baffles 42 are in contact with the workpiece or the processing table. When the slide bar 11 continues to descend, the baffle 42 remains in the bottom position, allowing the support rod 4 to slide in the middle of the slide rail 41.
