[0030] The clamping assembly is provided with a clamping assembly inside the fixed clamping block 2 and the sliding clamping block 5 for sliding.

[0031] Furthermore, according to the attached Figure 1 , attached Figure 2 and attached Figure 3 As shown, the moving assembly includes a fixed ring 8, and the fixed ring 8 is fixed to the bottom end of the inner wall of the device housing 1, a threaded rod 9 is slidably inserted inside the fixed ring 8, and a slider 10 is provided on the surface of the threaded rod 9 through a threaded sliding sleeve, and connecting blocks 11 are fixedly connected to both sides of the slider 10, and one end of the threaded rod 9 extending to the bottom end of the device housing 1 is fixedly sleeved with a turning button 6, and the use spacing can be adjusted by rotating it, which is more convenient to use.

[0032] Furthermore, according to the attached Figure 1 , attached Figure 2 and attached Figure 3 As shown, round rods 12 are fixedly connected to both sides of the inner wall of the device housing 1, and connecting blocks 11 are slidingly sleeved on the surface of the round rods 12 to increase the stability of the slider 10 when it moves and prevent deviation from affecting use.

[0033] Furthermore, according to the attached Figure 1 , attached Figure 2 and attached Figure 3 As shown, the slider 10 is slidably inserted into the inner wall of the device housing 1, and one end of the slider 10 is fixedly connected to one side of the sliding block 5, which can be adjusted according to the patient's oral condition to adapt to different patients.

[0034] Furthermore, according to the attached Figure 1 , attached Figure 4 and attached Figure 5 As shown, the snap-fit ​​assembly includes a special-shaped block 7, and the special-shaped block 7 is slidably inserted into the square groove 13. One end of the special-shaped block 7 is fixedly connected to a plastic clamp 14, and the top of the plastic clamp 14 is equidistantly provided with an anti-sliding block 15, so that the alveolar plate 3 can be quickly replaced to improve work efficiency.

[0035] Furthermore, according to the attached Figure 1 , attached Figure 4 and attached Figure 5 As shown, the plastic clamp head 14 is arranged to be inclined, and the plastic clamp head 14 is movably engaged with the square groove 13 at the top of the fixed clamp block 2, so that it can be stably engaged when clamped and used, and is also convenient for replacement.

[0036] Furthermore, according to the attached Figure 1 , attached Figure 4 and attached Figure 5The special-shaped block 7 is set to be "L"-shaped, and two groups of special-shaped blocks 7 are provided. One end of the two groups of special-shaped blocks 7 away from the fixed block 2 and the sliding block 5 is fixedly connected with the alveolar plate 3. The two groups of alveolar plates 3 are symmetrically arranged up and down, which effectively prevents poor infection between different patients and improves the safety of detection.

[0037] Working principle: When preparing for work, the special-shaped blocks 7 at one end of the two groups of alveolar plates 3 are movably engaged into the square grooves 13 of the fixed blocks 2. After the special-shaped blocks 7 enter the square grooves 13, the plastic clamps 14 are squeezed and move downward into the fixed blocks 2. One end of the plastic clamps 14 is engaged with the inner wall of the fixed blocks 2, so that the alveolar plates 3 can be fixed for use. After use, the plastic clamps 14 in the square grooves 13 are pressed outward, and the plastic clamps 14 drive the special-shaped blocks 7 and the alveolar plates 3 to be taken out and discarded. The anti-sliding block 15 increases the friction during use.

[0038] Next, holding the surface of the device housing 1, the two groups of alveolar plates 3 are placed in the patient's oral cavity, and then the knob 6 is turned according to the size of the patient's mouth. The rotation of the knob 6 drives the threaded rod 9 to rotate synchronously in the fixed ring 8. After the threaded rod 9 is turned to the right, the slider 10 moves downward on the surface of the threaded rod 9 through the thread, and the connecting blocks 11 at both ends of the slider 10 move downward on the surfaces of the two groups of round rods 12 at the same time. The slider 10 moves and slides downward in the slide groove 4, and the slider 10 drives the sliding block 5 and one group of alveolar plates 3 to move downward, so that the distance between the sliding block 5 and the fixed block 2 becomes larger, and the two groups of alveolar plates 3 gradually move away from each other. Holding the knob 6 and turning it to the right, the threaded rod 9 rotates in the opposite direction to drive the slider 10 and the sliding block 5 to move upward, so that the distance between the two groups of alveolar plates 3 becomes smaller.

[0039] The above is the entire working principle of the utility model.
