[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 6 In this embodiment of the utility model, an oral tongue depressor includes a fixed box 1, a grip handle 2 fixedly connected to the side of the fixed box 1, fixed blocks 3 fixedly connected to the upper and lower ends of the fixed box 1, a long rotating arm 4 rotatably connected to the inner side of the fixed block 3, a short rotating arm 6 rotatably connected between the two sets of long rotating arms 4, a silicone support plate 5 rotatably connected to one end of each of the two sets of long rotating arms 4, and a side moving ring 7 rotatably connected to the other end of the short rotating arm 6. A first support spring 8 is fixedly connected to the side of the side moving ring 7, and a side insertion port 9 penetrating its inner cavity is opened on the side of the fixed box 1.

[0023] In one embodiment, a rotating hook block 10 is rotatably connected to the inner side of the fixed housing 1, a second support spring 11 is fixedly connected to the side of the rotating hook block 10, a third support spring 12 is fixedly connected to the inner wall of the fixed housing 1, a stabilizing support top block 13 is fixedly connected to the other end of the third support spring 12, a slider limiting groove 19 penetrating the inner cavity is provided below the fixed housing 1, an unlocking slider 14 is slidably connected to the inner side of the slider limiting groove 19, a fourth support spring 15 is fixedly connected to the side of the unlocking slider 14, a replacement tongue plate 16 is provided on the side of the fixed housing 1, a locking groove 17 is provided below the replacement tongue plate 16, and a positioning baffle 18 is fixedly connected to the side of the replacement tongue plate 16.

[0024] During implementation, when the replacement tongue depressor 16 is inserted into the fixed housing 1 through the side insertion port 9, the rotating hook block 10 is squeezed and rotated by the replacement tongue depressor 16. Finally, under the action of the second support spring 11, it is locked into the locking groove 17 to complete the fixation. The stabilizing support top block 13, under the action of the third support spring 12, holds the inserted replacement tongue depressor 16 against the support, providing a stable locking state. The unlocking slider 14 is kept locked by the action of the fourth support spring 15. Pushing the unlocking slider 14 along the slider limit groove 19 squeezes the rotating hook block 10 to rotate, and under the action of the stabilizing support top block 13, the replacement tongue depressor 16 is ejected and replaced. The positioning baffle 18 ensures that the insertion depth of the replacement tongue depressor 16 is accurate.

[0025] In one embodiment, the side moving ring 7 is sleeved on the outside of the fixed box 1, and the two ends of the first support spring 8 are fixedly connected to the side moving ring 7 and the fixed box 1 respectively. When the first support spring 8 is naturally extended without being subjected to external force, the two sets of silicone support plates 5 are extended to the maximum extent. By moving the side moving ring 7 on the outside of the fixed box 1, the two sets of silicone support plates 5 can be contracted. The first support spring 8 is normally kept in an extended state, opening the patient's mouth and making the side moving ring 7 in the initial position. When an external force is applied to the side moving ring 7, axial displacement is achieved through the elastic deformation of the spring, and at the same time, the short rotating arm 6 is driven to produce an angle change. Then, the synchronous contraction of the two sets of silicone support plates 5 is controlled by the four-bar linkage mechanism. At this time, the oral tongue depressor can be better placed into the patient's mouth.

[0026] In one embodiment, a sliding groove is provided on the inner side of the fixed housing 1, and a slider adapted to the sliding groove is fixedly connected above the stabilizing support top block 13. The stabilizing support top block 13 is slidably connected to the inner wall of the fixed housing 1. The two ends of the fourth support spring 15 are fixedly connected to the unlocking slider 14 and the inner wall of the fixed housing 1, respectively. Under normal conditions, the fourth support spring 15 maintains the unlocking slider 14 at the rear end position of the slider limiting groove 19. When the unlocking slider 14 is pushed forward, its front inclined surface pushes the rotating hook block 10 to overcome the elastic force of the second support spring 11 and rotate, releasing the locking groove 17. At this time, the replacement pressure plate 16 can be removed. After being released, the fourth support spring 15 automatically resets.

[0027] When the replacement tongue plate 16 is fixed in place inside the fixed housing 1, the positioning baffle 18 is in close contact with the outside of the fixed housing 1. The positioning baffle 18 serves as a rigid limiting structure. When the replacement tongue plate 16 is inserted until the positioning baffle 18 contacts the outer wall of the fixed housing 1, it indicates that the locking groove 17 has accurately reached the snap-fit ​​position of the rotating hook block 10. At the same time, axial limiting is formed through planar contact to prevent the tongue plate from being over-inserted or loosened.

[0028] The working principle of this utility model is as follows: First, the replacement tongue depressor 16 is inserted into the fixed box 1 through the side insertion port 9 until the positioning baffle 18 is in close contact with the outside of the fixed box 1. During the insertion process, the replacement tongue depressor 16 presses the rotating hook block 10 to make it rotate. When the locking groove 17 reaches the position of the rotating hook block 10, the rotating hook block 10 is engaged in the locking groove 17 under the action of the second support spring 11, thus completing the fixing of the replacement tongue depressor 16. At the same time, the stabilizing support top block 13 supports the replacement tongue depressor 16 under the action of the third support spring 12, providing a stable locking state.

[0029] After the tongue depressor 16 is installed, move the side moving ring 7 on the outside of the fixed box 1 to make the first support spring 8 contract under external force, which drives the short rotating arm 6 and the long rotating arm 4 to rotate, thereby causing the silicone support plate 5 to contract. At this time, put the device into the patient's mouth, stop the lifting of the opposite side moving ring 7, and unfold the silicone support plate 5 to open the patient's mouth.

[0030] When it is necessary to replace the tongue depressor, push the unlocking slider 14 forward along the slider limit groove 19. The front inclined surface of the unlocking slider 14 pushes the rotating hook block 10 to rotate against the elastic force of the second support spring 11, releasing the locking groove 17. Under the action of the stabilizing support top block 13, the replacement tongue depressor 16 is popped out. At this time, it can be taken out and replaced with a new tongue depressor. After releasing the unlocking slider 14, the fourth support spring 15 automatically resets, and the unlocking slider 14 returns to the rear end position of the slider limit groove 19, ready for the next unlocking operation.

[0031] After replacing the tongue depressor, insert the new replacement tongue depressor 16 back into the fixed housing 1 and fix it in place, following the steps described above. Ensure that the silicone support plate 5 returns to its maximum extended state under the action of the first support spring 8 for future use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
