[0026] In the utility model, when in use, the pull rod 92 is pulled upward at the middle of the mounting block 91 to move the magnet 1 93 upward, compress the spring 94, and place the transparent protective cover 2 above the frame 1. At this time, the pull rod 92 is released, and the elastic force of the spring 94 is used to move the magnet 1 93 downward, so that the magnet 1 93 is inserted into the mounting groove 95 and contacts the magnet 2 96. The transparent protective cover 2 can be fixed above the frame 1 through the magnetic attraction between the magnet 1 93 and the magnet 2 96, thereby fixing the laser module 7. This design improves the The fixity of the laser module 7 prevents the transparent protective cover 2 from being offset due to external collision, thereby causing the drilling trajectory to be offset and affecting the drilling accuracy. The object to be drilled is passed horizontally through the transparent protective cover 2, and the electric push rod 5 is started to drive the clamping block 6 to move toward the middle to fix the object to be drilled. At this time, the position where the object is drilled faces upward to facilitate the positioning of the laser module 7. After positioning, the drill bit is driven to move downward and rotate so that the drill bit passes through the perforation 3 to drill the object to be drilled.

[0027] It should be noted that the laser module 7 is composed of a laser emitter, a lens, a reflector, a drive circuit and a controller. The laser beam emitted by the laser emitter is used to indicate or mark the drilling position. The lens is used to focus and adjust the direction of the laser beam to ensure that the laser can accurately irradiate the target surface. The reflector is used to guide the laser beam to the position where drilling is required, which can help achieve more precise positioning. The drive circuit, the circuit that controls the laser emitter, is used to provide the required current and voltage to activate the laser emitter. The controller is used to control the operation of the laser module 7, including switch control, laser beam adjustment and other functions. Embodiment 2
