[0047] like Figures 5 to 8 As shown, the angle adjustment assembly includes two arc plates 213, the two arc plates 213 are fixedly connected to the top of the rotating rod 201, a rotating shaft 214 is rotatably connected between the two arc plates 213, the mirror frame 102 is fixedly connected to the rotating shaft 214, the outer surface of the rotating shaft 214 is fixedly connected to a second gear 215, a rectangular groove 216 is opened in the middle of the rotating rod 201, and a connecting rod 217 is slidably connected to the inner wall of the rectangular groove 216, and the connecting rod 217 is slidably connected to the inner wall of the rectangular groove 216. The top of the connecting rod 7 is fixedly connected with a second rack plate 218, and the second rack plate 218 is meshed with the second gear 215. The bottom end of the connecting rod 217 is fixedly connected with a push rod 219, and the push rod 219 slides through one end of the connecting plate 210. The end of the push rod 219 away from the connecting rod 217 is fixedly connected with a round block 220. The holding rod 101 is provided with an arc-shaped opening 221, and the push rod 219 slides through the arc-shaped opening 221. A fixing component is arranged on the push rod 219.

[0048] When the angle of the oral mirror body 103 needs to be adjusted, the round block 220 is pushed, and the round block 220 drives the push rod 219 and the connecting rod 217 to slide in the rectangular groove 216, and the connecting rod 217 drives the second rack plate 218 to slide, and the second rack plate 218 drives the second gear 215 to rotate, and the second gear 215 drives the rotating shaft 214 to rotate, and the rotating shaft 214 drives the oral mirror body 103 to rotate, and the angle of the oral mirror body 103 is adjusted. When the oral mirror body 103 is adjusted to an angle that is convenient for observing the patient's oral cavity, the push rod 219 is restricted by the fixing component to facilitate the observation requirements of different areas and angles in the patient's oral cavity, so as to facilitate the staff to observe the details inside the patient's oral cavity more clearly. By providing the arc-shaped opening 221, when the rotating rod 201 is rotating, the rotating rod 201 can drive the push rod 219 to slide in the arc-shaped opening 221, so as to avoid affecting the angle adjustment of the oral mirror body 103 by the angle adjustment component.

[0049] like Fig. 9 As shown, the fixed component includes a rectangular shell 222, which is slidably connected to the outer surface of the push rod 219, and the inner wall of the rectangular shell 222 is slidably connected with a moving block 223, and a second spring 224 is fixedly connected between the rectangular shell 222 and the moving block 223, and the front end of the moving block 223 is fixedly connected with a pushing block 225, and the pushing block 225 slides through the front end of the rectangular shell 222, and the top of the moving block 223 is fixedly connected with an insertion rod 226, and the insertion rod 226 slides through the upper end of the rectangular shell 222, and a plurality of sockets 227 that cooperate with the insertion rod 226 are provided on the push rod 219, and a circular arc plate 228 is fixedly connected to the outer surface of the holding rod 101, and a plurality of sockets 229 are provided at the lower end of the circular arc plate 228.

[0050] When it is necessary to fix the push rod 219, push the push block 225, and the push block 225 drives the moving block 223 to slide in the rectangular shell 222, the second spring 224 is compressed, and the moving block 223 drives the insertion rod 226 to leave the socket 229 and the socket 227. Then, adjust the angle adjustment component, and when the oral mirror body 103 is adjusted to a suitable angle, release the push block 225, the second spring 224 rebounds, and the moving block 223 drives the insertion rod 226 to pass through the socket 227 and insert it into the socket 229 on the arc plate 228, thereby restricting the push rod 219 to prevent the push rod 219 from sliding freely and affecting the angle adjustment of the oral mirror body 103.

[0051] like Fig.10 and Fig.11As shown, a circular tube 230 is fixedly connected to the middle part of the oral mirror body 103, and a plurality of liquid outlet pipes 231 are fixedly connected to the outer surface of the circular tube 230, and the plurality of liquid outlet pipes 231 pass through the inner side of the mirror frame 102.

The inner wall of the hollow rod 239 is rotatably connected to a sealing plate 242, and the top of the sealing plate 242 is fixedly connected to a rotating block 243.

[0056] When it is necessary to squeeze the liquid capsule 233, the rectangular block 240 is pushed, and the rectangular block 240 drives the hollow rod 239 to move, and the hollow rod 239 drives the squeezing plate 238 to squeeze the cleaning liquid in the liquid capsule 233, so that the cleaning liquid cleans the oral mucus and impurities attached to the surface of the oral mirror body 103. When it is necessary to add cleaning liquid to the liquid capsule 233, the cleaning liquid is added into the hollow rod 239 through the liquid inlet hole 241 on the rectangular block 240, and enters the liquid capsule 233 through the hollow rod 239. After the addition is completed, the rotary block 243 is twisted, and the rotary block 243 drives the sealing plate 242 to seal the hollow rod 239 to prevent the cleaning liquid in the liquid capsule 233 from flowing out.

[0058] By providing the lighting lamp 244, the lighting lamp 244 can improve the lighting level for the staff to observe the patient's oral cavity and improve the accuracy of observation.

[0059] The workflow of the technical solution of the present invention is as follows:

[0060] When in use, the staff holds the holding rod 101 and places the oral mirror body 103 in the patient's mouth, pulls the handle 208 upwards, the handle 208 drives the slider 207 to slide in the rectangular sleeve 206, the first spring 209 is compressed, the slider 207 drives the connecting plate 210 to move upwards, the connecting plate 210 drives the pin 211 to leave the slot 212, and then, pushes the push block 205 to drive the first rack plate 204 to slide in the fixed frame 203 and the rotating rod 201, the first rack plate 204 drives the first gear 202 to rotate, the first gear 202 drives the rotating rod 201 to rotate, and the rotating rod 201 drives the mirror frame 102 and the oral mirror body 103 to rotate.

[0061] When the oral mirror body 103 is rotated to an angle convenient for observing the patient's oral cavity, the handle 208 is released, the first spring 209 rebounds, the slider 207 drives the connecting plate 210, and the connecting plate 210 drives the latch 211 to be inserted into the slot 212 on the first rack plate 204, restricting the first rack plate 204, so that the staff can check the patient's oral cavity from all directions. Then, the pushing block 225 is pushed, and the pushing block 225 drives the moving block 223 to slide in the rectangular shell 222, the second spring 224 is compressed, and the moving block 223 drives the insertion rod 226 to leave the socket 229 and the socket 227, and then the round block 220 is pushed to drive the push rod 219 and the connecting rod 217 to slide in the rectangular groove 216. The second rack plate 218 drives the second gear 215 to rotate, and the second gear 215 drives the rotating shaft 214 to rotate. The rotating shaft 214 drives the oral mirror body 103 to rotate, and the angle of the oral mirror body 103 is adjusted. When the oral mirror body 103 is adjusted to an angle convenient for observing the patient's oral cavity, the pushing block 225 is released, the second spring 224 rebounds, and the moving block 223 drives the insertion rod 226 to pass through the socket 227 and insert into the socket 229 on the arc plate 228, thereby restricting the push rod 219, so as to adapt to the observation needs of different areas and angles in the patient's oral cavity, and the staff can observe the details inside the patient's oral cavity more clearly.

[0062] Then, the patient's oral cavity is illuminated by multiple lighting lamps 244 on the mirror frame 102, which improves the staff's observation of the patient's oral lesions. When it is necessary to clean the oral mucus and impurities attached to the surface of the oral mirror body 103, the cleaning liquid is added into the hollow rod 239 through the liquid inlet hole 241 on the rectangular block 240, and enters the liquid capsule 233 through the hollow rod 239. After the addition is completed, the rotary block 243 is twisted, and the rotary block 243 drives the sealing plate 242 to seal the hollow rod 239. Then, the rectangular block 240 is pushed, and the rectangular block 240 drives the hollow rod 239 to move, and the hollow rod 239 drives the squeezing plate 238 to squeeze the cleaning liquid in the liquid capsule 233, so that the cleaning liquid generates pressure and quickly enters the hose 232. The cleaning liquid in the hose 232 enters the liquid outlet pipe 231 through the annular tube 230. Under the pressure of the liquid capsule 233 being squeezed, the cleaning liquid can push the sealing ball 236 away from the liquid outlet 235 on the truncated cone 234. The elastic rope 237 is stretched. While the sealing ball 236 is pushed away, the cleaning liquid can flow out through the gap between the liquid outlet 235 and the sealing ball 236, so that the cleaning liquid is released to the surface of the oral mirror body 103, and the oral mucus and impurities attached to the surface of the oral mirror body 103 are cleaned. The cleaning liquid in the patient's mouth can be discharged through the negative pressure device. After the cleaning liquid flows out, the elastic rope 237 rebounds, driving the sealing ball 236 to engage with the liquid outlet 235, thereby sealing the liquid outlet 235 on the truncated cone 234.

[0063] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
