[0024] Working principle: When using the device, the plaster model is placed on the top of the disc 304, and the infrared emitter 7 is activated to emit infrared rays, so that the plaster model can be conveniently positioned, and the electric guide rail 502 on the protective plate 501 is activated to drive the electric slider 503 to move, thereby driving the moving block 504 and the connecting block 505 to move downward, and finally the plaster model is pressed down and fixed by the pressing block 6, so that the motor 301 is started to generate power and drive the rotating rod 302 at the output end to rotate, driving the drill body 303 to perform drilling operations, and the inner wall through groove allows the drill body 303 to pass smoothly and complete the positioning drilling operation; During the downward pressure process, the downward pressure block 6 squeezes the lifting block 204 and the disc 304, so that the lifting block 204 drives the connecting slider 202 to move downward, so that the limit slider 203 slides on the top of the fixed block 201, and provides elastic buffering and reset functions under the action of multiple springs 205, so that when the lifting block 204 descends, the drill body 303 will leak out, so as to facilitate drilling. When the downward pressure disappears, the lifting block 204 will rise under the rebound action of the spring 205, so as to be higher than the drill body 303, so that the drill body 303 can be effectively protected; When the moving block 504 is pressed down and raised, it will drive the connecting block 505 to move, so that one end of the connecting rod 402 drives the piston 406 to move in the sleeve 401, thereby squeezing the gas in the sleeve 401, and introducing air through the inlet pipe 403 and the one-way valve 405, and the outlet pipe 404 discharges the air flow through the one-way valve 405, and the air flows through the internal filter screen to complete the filtration, and finally the dust generated by drilling the hole from the outlet pipe 404 to the top of the disc 304 is cleaned; The infrared positioning module uses the infrared transmitting unit to roughly locate the drilling area to ensure the initial accuracy of the position. The depth control module then uses the depth sensor to measure the drilling depth in real time, and combines it with the depth preset unit for dynamic comparison and feedback to ensure that the depth is accurate and consistent. The plaster model is then drilled through the drilling module, and the support unit is used to provide stable support and reduce vibration errors. Finally, the monitoring and feedback module uses the position sensor and depth feedback unit to monitor the drilling position and depth in real time. If the deviation exceeds the threshold, an alarm feedback is automatically issued to ensure operational accuracy.
