With continued reference to fig. 7 and 8, an adjusting lever 21 is rotatably connected to the extension lever 19 in the direction perpendicular to the adjusting bracket 20, and the adjusting lever 21 abuts against the adjusting bracket 20. Specifically, a threaded hole is formed in the direction of the extension rod 19 perpendicular to the adjusting frame 20, the threaded hole is located below the adjusting frame 20, one end of the adjusting rod 21 is provided with threads, the threads are connected with the extension rod 19 through the threaded hole, after the angle of the adjusting frame 20 is adjusted, the adjusting rod 21 can be screwed down until the adjusting rod abuts against the adjusting frame 20, at the moment, the adjusting frame 20 is locked, the suction angle is stable, and a doctor can conveniently suck dental pulp.
Further, a flexible tube 22 is connected to one end of the adjusting rod 21 far from the extension rod 19, and a light emitting member 23 is arranged at one end of the flexible tube 22 far from the adjusting rod 21. Specifically, by arranging the flexible tube 22 and the light emitting member 23, a doctor can irradiate light emitted by the light emitting member 23 on teeth of a patient by adjusting the angle of the flexible tube 22, so that the doctor can accurately find out an affected part to perform dental pulp suction.
Example two
Referring to fig. 9, the dental pulp aspirator in this embodiment has the same structure as that in the first embodiment, and electromagnetic valves 25 with the same aperture are provided in the hollow tube 4 and the pressure release hole, and electromagnets 24 are provided on the piston plate 9, so as to control the movement of the piston plate 9. Specifically, when the piston plate 9 is not required to slide greatly, the electromagnet 24 can be electrified to generate magnetism, so that the electromagnet and one side of the hand-held cylinder 1 close to the tooth root file main body 2 are attracted mutually to offset the adsorption force generated in the hand-held cylinder 1 when the air pump continuously pumps air, thereby reducing the sliding amplitude of the piston plate 9 and avoiding damage to a patient and the second elastic piece 17; when a large sliding movement of the piston plate 9 is required, the hollow tube 4 can be closed by opening the solenoid valve 25, so that the pressure in the hand-held cartridge 1 is instantaneously reduced, and the piston plate 9 can rapidly move away from the root file body 2. Meanwhile, the electromagnetic valve 25 in the pressure relief hole can control the release of air pressure between the plug-in block 5 and the hollow sliding sleeve 7.
