The micro reduction motor 305 can drive the threaded screw 303 at a uniform and slow speed through the pulley rod to prevent the upper tooth top block 1 from moving too fast and causing oral discomfort to the patient. A proximity switch 306 is fixedly connected to the outside of the support tube 301. The sensing end on the right side of the proximity switch 306 is connected to the signal of the sensing sheet on the left side of one of the lifting blocks 304 to prevent the upper tooth top block 1 from being lifted excessively.

[0025] The auxiliary component 4 includes a multi-jointed tube 401, an LED shadowless lamp 402 and a miniature camera 403. The bottom of the upper tooth top block 1 is fixedly connected with the multi-jointed tube 401, and the multi-jointed tube 401 can be bent in any direction. The bottom of the multi-jointed tube 401 is fixedly connected with the LED shadowless lamp 402, which is a special lighting fixture for surgery. The bottom of the upper tooth top block 1 is fixedly installed with a miniature camera 403, and the miniature camera 403 is connected to the external display signal to transmit the internal image of the oral cavity to the external display, which is convenient for the doctor to observe and operate.

[0031] according to Figure 2 and Figure 3As shown, the inner tooth grooves of the upper tooth top block 1 and the lower tooth top block 2 are respectively engaged to support the upper and lower gums inside the oral cavity, the telescopic rod 302 moves in the internal slide groove of the support tube 301, and the top of the telescopic rod 302 is connected to support the upper tooth top block 1, and the opening arc of the oral cavity is adjusted by lifting the upper tooth top block 1.

[0032] according to Figure 2 and Figure 3 As shown, the inner left wall and the inner right wall of the internal slide groove of the support cylinder 301 are both provided with vertical grooves, the left and right sides of the lifting block 304 are slidably connected to the vertical grooves, the bottoms of the two threaded screws 303 are connected to the No. 1 pulley rod, and the two No. 1 pulley rods are connected to the No. 2 pulley rod through belts, which can ensure that the two threaded screws 303 synchronously drive the lifting block 304 to move up and down.

[0033] according to Figure 2 and Figure 3 as well as Figure 4 As shown, when the micro reduction motor 305 drives the No. 2 pulley rod, the two No. 1 pulley rods drive the two No. 2 pulley rods to rotate synchronously. At this time, the two lifting blocks 304 drive the two telescopic rods 302 to rise synchronously to lift and support the upper tooth top block 1.

[0034] according to Figure 2 and Figure 3 as well as Figure 5 As shown, the proximity switch 306 is located at the top left side of one of the support cylinders 301, and the right sensing end of the proximity switch 306 is connected to the sensing sheet signal on the left side of one of the lifting blocks 304. The proximity switch 306 is a switch-type sensor, i.e., a contactless position switch, which works internally based on the electromagnetic induction principle. When the sensing sheet moves to the sensing end of the proximity switch 306, the proximity switch 306 provides an opening and closing control instruction for the micro reduction motor 305.
