Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 7 The present invention provides a technical solution: a multi-angle adjustable dental high-speed handpiece, comprising an upper shell 1 and a lower shell 2, a polishing shell 3 fixedly mounted on one end of the upper shell 1, a turbine polishing assembly mounted inside the polishing shell 3, six connecting pipes 23 fixedly mounted inside the upper shell 1, an inner rotating seat 24 fixedly mounted on the end of the upper shell 1 away from the polishing shell 3, an adjusting gear 25 fixedly mounted on the outer side of the inner rotating seat 24, a rotating sleeve 5 fixedly mounted on the outer side of the end of the upper shell 1 away from the polishing shell 3, a rotating magnetic ring 13 fixedly mounted on the bottom of the rotating sleeve 5, a fixed sleeve 4 fixedly mounted on the outer side of one end of the lower shell 2, an annular rotating groove 32 is provided on the top of the fixed sleeve 4, and the upper shell 1 is rotatably mounted on the top of the lower shell 2. The rotating sleeve 5 is rotatably installed on the top of the fixed sleeve 4, the rotating magnetic ring 13 is rotatably installed inside the annular rotating groove 32, the inside of the annular rotating groove 32 is fixedly installed with an electromagnet 33, the outside of the fixed sleeve 4 is fixedly installed with a protective shell 7, the inside of the protective shell 7 is rotatably installed with two adjusting wheels 8, an adjusting gear 1 9 is fixedly installed between the adjusting wheels 8, the adjusting gear 1 9 and the adjusting gear 2 25 are in the same horizontal plane, the outside of the adjusting gear 1 9 and the outside of the adjusting gear 2 25 are meshed, a button 10 is installed on the outside of the fixed sleeve 4, an outer ring 19 is fixedly installed on the end of the lower shell 2 away from the fixed sleeve 4, an inner rotating ring 21 is rotatably installed inside the outer ring 19, and a terminal head 20 is fixedly installed inside the inner rotating ring 21.

[0025] The working principle of the above technical solution is: first, the matching dental chair is connected to the outside through the terminal head 20, and then the grinding shell 3 is placed inside the patient's mouth, and the patient's teeth are trimmed by the turbine grinding assembly. When the direction of the turbine grinding assembly needs to be changed, it is divided into coarse adjustment and fine adjustment. First, the rotating sleeve 5 can be rotated to make the rotating magnetic ring 13 rotate inside the annular groove 32, and the upper shell 1 can be rotated at the end of the lower shell 2, thereby driving the grinding shell 3 to rotate, thereby coarsely adjusting the direction of the turbine grinding assembly, and then the medical staff manually pushes the adjusting wheel 8 to rotate, thereby driving the adjusting gear 9 to rotate, thereby driving the adjusting gear 10 to rotate. Gear 2 25 rotates, thereby driving the upper shell 1 to rotate through the inner rotating seat 24. Because the gear ratio between the adjusting gear 1 9 and the adjusting gear 2 25 is 1:8, the adjusting gear 1 9 rotates one circle and the adjusting gear 2 25 rotates one-eighth of a circle, thereby driving the upper shell 1 to rotate slowly, prompting the grinding shell 3 to drive the turbine grinding assembly to rotate slowly, thereby achieving fine adjustment of the direction of the turbine grinding assembly and improving the adjustment accuracy. In addition, after the adjustment is completed, the button 10 can be pressed to energize the electromagnet 33 to generate magnetic force, thereby adsorbing and fixing the rotating magnetic ring 13, thereby preventing the upper shell 1 from rotating during use and ensuring the normal use of the device.

[0026] In another embodiment, Figure 1-Figure 7As shown, the turbine grinding assembly includes a master-slave turbine block 27 and a driven turbine block 31.

A grinding head 14 is clamped and installed inside the assembly seat 30. A clamping groove 28 is provided inside the end of the master-slave turbine block 27 away from the rotating column 26. A clamping column 29 is fixedly installed on the top of the driven turbine block 31 away from the assembly seat 30.

[0027] After being connected to the matching dental chair through the connection head 20, gas can be output through one of the connecting pipes 23 to blow the master-slave turbine block 27, so that the master-slave turbine block 27 rotates, thereby driving the driven turbine block 31 to rotate through the clamping column 29, thereby driving the grinding head 14 to rotate at high speed through the assembly seat 30 to grind and repair the patient's tooth. In addition, the gas inside the grinding shell 3 will be discharged through another connecting pipe 23. In addition, cleaning water can be transported through one of the connecting pipes 23 and then atomized and sprayed out through the atomizing nozzle 18. , the grinding head 14 is used to rinse the patient's teeth when grinding them. In addition, one of the connecting tubes 23 can be used to extract the airflow inside the oral cavity through two filter membranes 17 when the grinding head 14 is grinding the patient's teeth. In addition, the endoscope 12 can be used to take pictures of the inside of the oral cavity, which is convenient for medical staff to understand the situation inside the patient's oral cavity in time, and to confirm the area of ​​the patient's teeth that needs to be trimmed, confirm the repair volume, and facilitate the subsequent grinding of the patient's teeth through the grinding head 14.

[0030] Working principle: First, connect the matching dental chair through the terminal 20, then place the grinding shell 3 inside the patient's mouth, and trim the patient's teeth through the turbine grinding assembly. When the direction of the turbine grinding assembly needs to be changed, it is divided into coarse adjustment and fine adjustment. First, the rotating sleeve 5 can be rotated to make the rotating magnetic ring 13 rotate inside the annular rotating groove 32, and the upper shell 1 can be rotated at the end of the lower shell 2, thereby driving the grinding shell 3 to rotate, thereby coarsely adjusting the direction of the turbine grinding assembly, and then the medical staff manually pushes the adjusting wheel 8 to rotate, thereby driving the adjusting gear 9 to rotate, Thereby, the adjusting gear 2 25 is driven to rotate, thereby driving the upper shell 1 to rotate through the inner rotating seat 24. Because the gear ratio between the adjusting gear 1 9 and the adjusting gear 2 25 is 1:8, the adjusting gear 1 9 rotates one circle and the adjusting gear 2 25 rotates one eighth of a circle, thereby driving the upper shell 1 to rotate slowly, prompting the grinding shell 3 to drive the turbine grinding assembly to rotate slowly, thereby achieving fine adjustment of the direction of the turbine grinding assembly and improving the adjustment accuracy. In addition, after the adjustment is completed, the button 10 can be pressed to energize the electromagnet 33 to generate magnetic force, thereby adsorbing and fixing the rotating magnetic ring 13, thereby preventing the upper shell 1 from rotating during use. The shell 1 rotates to ensure the normal use of the device. After being connected to the matching dental chair through the terminal head 20, gas can be output through one of the connecting pipes 23 to blow the master-slave turbine block 27, so that the master-slave turbine block 27 rotates, thereby driving the driven turbine block 31 to rotate through the clamping column 29, thereby driving the grinding head 14 to rotate at high speed through the assembly seat 30 to grind and repair the patient's tooth. In addition, the gas inside the grinding shell 3 will be discharged through another connecting pipe 23. In addition, cleaning water can be transported through one of the connecting pipes 23, and then atomized and sprayed through the atomizing nozzle 18. The grinding head 14 rinses the patient's teeth while grinding them. In addition, one of the connecting tubes 23 can extract the airflow inside the oral cavity through two filter membranes 17 when the grinding head 14 grinds the patient's teeth. In addition, the endoscope 12 can be used to take pictures of the inside of the oral cavity, which is convenient for medical staff to understand the situation inside the patient's oral cavity in time, and to confirm the area of ​​the patient's teeth that needs to be trimmed, confirm the repair volume, and facilitate the subsequent grinding of the patient's teeth through the grinding head 14.
