Through the mutual cooperation of the guide inclined groove 207 and the lifting and pressing shaft 205, the positioning plug plate 206 can slide along the inner wall of the movable frame 7 under the pressure of the lifting and pressing shaft 205;

[0045] A pressing component is provided on the lifting and pressing shaft 205, and the pressing component is used to limit the lifting and pressing shaft 205;

[0046] In one embodiment, Figures 1-4 As shown, the pressing assembly is a pressing push block 204 fixedly connected to the outer wall of the lifting and pressing shaft 205. The pressing push block 204 passes through the positioning plug plate 206 to the top outside of the movable frame 7.

[0049] The above embodiment discloses a medical mouth opener, wherein, when in use, the knob 5 is rotated, and the knob 5 can drive the bidirectional screw 3 to rotate through the connecting shaft. At the same time, the two movable sliders 4 are driven by the outer wall threads of the bidirectional screw 3 to move along the inner wall of the adjustment frame 1. At this time, the movable frame 7 is driven by the movable slider 4 to drive the opening plate 6 to move synchronously through the positioning sleeve 202 and the docking column 208, so that the distance between the two opening plates 6 can be adjusted according to the actual situation of the patient;

[0050] When the distance between the two opening plates 6 is adjusted, one opening plate 6 is moved to a side of a moving frame 7 away from the other moving frame 7. At the same time, the docking post 208 moves one end of the positioning sleeve 202 under the drive of one opening plate 6. Then, one opening plate 6 is pushed to make the docking post 208 pass through the other side of the positioning sleeve 202. During this process, the two limiting blocks 209 slide into the inside of the limiting slide 201 under the drive of the docking post 208 until the limiting block 209 contacts the inner wall of one side of the limiting slide 201, thereby limiting the sliding of the docking post 208.

[0051] At the same time, the docking post 208 is accurately inserted into the interior of the positioning sleeve frame 202 through the outer wall of the square table. When the outer wall of the docking post 208 contacts the outer wall of the positioning plug plate 206 with the inclined surface, the positioning plug plate 206 slides along the inner wall of the movable frame 7 under the pressure of the docking post 208, and the compression spring 203 is contracted. At the same time, the positioning plug plate 206 squeezes the outer wall of the lifting and pressing shaft 205 through the guide inclined groove 207. At this time, the pressing push block 204 is pushed along the lifting and pressing shaft 205 under the pressure of the inner wall of the guide inclined groove 207. As the inner wall of the movable frame 7 slides down, when the positioning slot moves to the end of the positioning plug plate 206 under the drive of the docking plug post 208, the spring 203 pushes the positioning plug plate 206 into the interior of the positioning slot by rebounding. At the same time, the pressing block 204 slides back along the inner wall of the movable frame 7 under the extrusion and guidance of the inner wall of the guide inclined groove 207 through the lifting and pressing shaft 205, thereby realizing the convenient engagement and fixation of the docking plug post 208. Then, the operation is repeated for the other open plate 6, thereby realizing the convenient installation of the two open plates 6.

[0052] When the expansion plate 6 needs to be replaced after use, the above operation is reversed by squeezing and pressing the push block 204, so that the two expansion plates 6 can be easily disassembled, thereby further improving the replacement efficiency of the expansion plates 6, so as to further reduce the time required for replacing the expansion plates 6 during oral examinations of different patients.

[0053] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
