The working principle of the orthodontic auxiliary device in the above technical solution is described as follows:

In orthodontic clinics, patients need to open their mouths wide to ensure enough operating space for medical personnel to perform treatment operations. Because a certain amount of time is required during treatment, in order to prevent patients from keeping their mouths wide open during this process, it is necessary to go to the Orthodontic auxiliary equipment is placed in the oral cavity. When the equipment is placed, the upper bracket 1 is in contact with the patient's upper jaw, while the lower bracket 4 is located at the position of the patient's tongue. The driver 2 is connected to the first telescopic rod 3 and the second telescopic rod 5 Using electrical connection, the driver 2 controls the first telescopic rod 3 and the second telescopic rod 5 to be in the best fixed state. After the upper bracket 1 and the lower bracket 4 are fixed, the cover film matched with the U-shaped cushion surface 11 12 are tightly attached to the upper jaw and the tongue, the contact surface of the U-shaped cushion surface 11 is a sponge layer 111, which will not bring discomfort to the patient, and the contact area is expanded to the entire oral cavity, reducing the patient's pain during use;

Before use, the staff needs to fix the engaging component 112 with the sponge layer 111 in the card slot 15. During the fixing process, the card block 12b goes straight into the card slot 15, and the protruding parts on both sides are engaged with the concave parts. , when the block 12b directly enters the interior of the card slot 15, it will make a sound when it comes into contact with the first piston a, and when a "click" is heard, the fixation is successful, so that the device can be put into use;

After use, the worker uses a glass tube to penetrate into the restriction hole 141, and uses the glass tube to continuously squeeze the second piston 142, which is the change of the pressure inside the air chamber 143, and uses the pressure to push out the first piston a to push the second piston 142 out. The clamping block 12b is ejected from the clamping slot 15, then, the plywood 2a1 is opened, and the sponge layer 111 can be removed from the splint 12a. The sponge layer 111 is for one-time use and is also very convenient to replace, and the sponge layer 111 The contact comfort can be improved, and at the same time, the sponge can absorb the saliva of the patient's mouth, and during the treatment period, the frequency of the patient's spit can be reduced, so that the sponge layer 111 can be used comprehensively.

The electrical signal system (relays, sensors, circuit boards, etc.) inside the above-mentioned driver 2 is controlled by a computer to drive the expansion and contraction, which can be realized in the prior art. To the pneumatic telescopic rod, electric telescopic rod and so on.
