The lifting adjustment connecting rod 5 is fitted and slidably arranged on the bottom connecting frame 4. The top head cover 6 is arranged on the top of the lifting adjustment connecting rod 5. The facial proportion comparison mesh cover 3 is fixedly connected between the bottom connecting frames 4. The side adjustment and correction component 1 is arranged on the bottom connecting frame 4 in two groups.

[0022] As Figures 4 - 7 shown, the side adjustment and correction component 1 includes water-absorbing resin particles 7, a particle conveying elbow 8, a particle pushing rod 9, a fixed end 10, a mobile end 11, an expansion joint 12, a side contact correction pad 13 and a side correction support plate 14. The side correction support plate 14 is fixedly connected to the bottom connecting frame 4. The fixed end 10 is arranged on the side correction support plate 14. The expansion joint 12 is communicated with the fixed end 10. The mobile end 11 is communicated with the expansion joint 12. The particle conveying elbow 8 is communicated and arranged on the top of the fixed end 10. The water-absorbing resin particles 7 are arranged on the horizontal part of the particle conveying elbow 8. The side contact correction pad 13 is fixedly connected to the mobile end 11. The particle pushing rod 9 is fixedly connected to the side contact correction pad 13.

[0023] As Figures 2 - 3As shown, the support adjustment assembly 2 includes a support adjustment motor 15, an adjustment lead screw 16, a mandibular swing clamping plate 17, a side moving plate 18, a support bottom plate 19, and a protective partition plate 20. The support bottom plate 19 is fixedly connected to the bottom connection frame 4, the protective partition plate 20 is fixedly connected to the support bottom plate 19, the mandibular swing clamping plate 17 is hinged to the support bottom plate 19, the side moving plate 18 is hinged to the mandibular swing clamping plate 17, the body of the support adjustment motor 15 is disposed on the outer wall of the side moving plate 18. There are two groups of side moving plates 18. One group of side moving plates 18 is fixedly connected through one end of the adjustment lead screw 16, and the other group of side moving plates 18 movably penetrates through the other end of the adjustment lead screw 16. A soft pad 21 is provided on the mandibular swing clamping plate 17.

[0024] As Figure 2 shown, the protective partition plate 20 is located at one end close to the adjustment lead screw 16.

[0025] As Figure 1 shown, a number of pin holes 23 are provided on the lifting adjustment link 5, and an adjustment pin 22 is provided on the side wall of the bottom connection frame 4. The height of the lifting adjustment link 5 and the top hood 6 is adjusted by inserting the adjustment pin 22 into different pin holes 23 on the lifting adjustment link 5, so as to adapt to different patients.

[0026] As Figures 1 - 3 shown, there are four groups of mandibular swing clamping plates 17, and the side adjustment and correction assembly 1 penetrates through the four groups of mandibular swing clamping plates 17. The bottom connection frame 4 is in an L shape.

[0027] As Figure 4 shown, the particle pushing rod 9 moves in the horizontal part of the particle conveying elbow 8.

[0028] As Figure 2 shown, the output end of the support adjustment motor 15 is connected to the adjustment lead screw 16.

[0029] As Figure 1 shown, the top hood 6 is made of silica gel material.

[0030] During specific use, the patient places the mandible on the support base plate 19. The soft pads 21 on the mandible swing clamping plates 17 enhance the comfort of the patient during wearing. The support adjustment motor 15 is activated, and then the adjustment screw rod 16 rotates, driving the two sets of side moving plates 18 to approach each other. Consequently, the four sets of mandible swing clamping plates 17 swing accordingly, and the mandible of the patient is initially corrected and fixed through the soft pads 21. The protective partition plate 20 separates the adjustment screw rod 16, preventing the patient from accidentally touching it and enhancing safety. When local correction of the patient's mandible is required, the protruding part of the mandible will push the side contact correction pad 13 outwards. Then, the side contact correction pad 13 drives the mobile end 11 and the expansion joint 12 to contract. Meanwhile, the particle propulsion rod 9 moves synchronously, driving the water-absorbing resin particles 7 to move from the horizontal part of the particle conveying elbow 8 to the vertical part of the particle conveying elbow 8, and then falling into the fixed end 10, accumulating in the fixed end 10 and the expansion joint 12. There is water stored in the expansion joint 12 in advance. Thus, the water-absorbing resin particles 7 entering the expansion joint 12 absorb the water, causing their volume to expand and gradually filling the space in the expansion joint 12. Then, the expansion joint 12 elongates, applying forces in opposite directions to the local part of the patient that needs correction through the side contact correction pad 13, thereby performing local correction on the patient. This solution realizes the automatic pressing on the protruding part of the patient's mandible through the side adjustment correction assembly 1, thereby performing automatic correction in a specific direction. When the offset of the protruding part of the patient's mandible decreases, the side contact correction pad 13 no longer presses on the protruding part of the patient's mandible, and the device can be removed from the patient's mandible. During the process of wearing this device, by using the facial proportion comparison mesh cover 3 as a reference, the correction change of the patient's mandible can be observed.
