[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The support assembly provided in the present invention can keep the mouth open for younger children by external support, thereby avoiding the occupation of the internal space of the patient's mouth by internal support. When using the device to support the patient's mouth, first adjust the clamping assembly according to the size of the patient's head, turn the knob in the adjustment assembly, so that the first screw connected to the knob coaxially drives the movable plate screwed thereon to slide along the two guide strips. At this time, the movable plate will pull the limit button provided on one side thereof, so that the two groups of limit buttons move outward synchronously. Since the limit button is provided at both ends of the first rope loop and the second rope loop, the distance between all the fastening belts will be shortened when the movable plate moves outward, so that the soft guide plate provided at one end of the fastening belt slides along the arc groove opened at one end of the adjacent fastening belt. After tightening to the size equivalent to the patient's head, the ring formed by the fastening plate is placed on the patient's head through the pad connected to its bottom end, and then the knob is rotated until the pad clamps the patient's head. At this time, the device is fixed to the patient's head.

[0018] (2) The control component provided in the present invention can lock the angle of the push rod in the support component to prevent the push rod from rotating freely and slipping off the patient's mandible. After the push rod is pressed against the patient's mandible, the fan gear and the connecting arm connected to the outside of the fan gear are slid along the longitudinal rod until the occlusal pad clamped at the free end of the connecting arm is equal to the height of the patient's oral cavity. At this time, the connecting arm can be rotated inward to place the occlusal pad in the patient's non-operative side oral cavity. During the rotation of the connecting arm, the fan gear on which it is located will be driven to rotate, locking the position of the slide rod. Since the control frame provided at one end of the slide rod is sleeved on the side rod outside the push rod, when the slide rod position is locked, the angle direction of the push rod is synchronously locked.

[0039] The specific usage and function of this embodiment are as follows:

[0040] The support assembly provided in the present invention can keep the patient's mouth open by external support for younger children, avoiding the occupation of the internal space of the patient's oral cavity by internal support. When using the device for patient oral support, first adjust the clamping assembly according to the size of the patient's head, turn the knob in the adjustment assembly, so that the first screw 35 coaxially connected to the knob drives the movable plate 6 screwed thereon to slide along the two guide strips 34, at this time, the movable plate 6 will pull the limit button 5 provided on one side thereof, so that the two groups of limit buttons 5 move outward synchronously. Since the limit button 5 is provided at both ends of the first rope loop 8 and the second rope loop 8, the distance between all the fastening belts 3 will be shortened when the movable plate 6 moves outward, so that the soft guide plate 11 provided at one end of the fastening belt 3 slides along the arc groove 9 opened at one end of the adjacent fastening belt 3. After being tightened to a size equivalent to the patient's head, the ring formed by the fastening plate is placed on the patient's head through the pad 10 connected to its bottom end, and then the knob is rotated until the pad 10 clamps the patient's head, at this time, the device is fixed to the patient's head.

[0041] When the patient needs to keep his mouth open, the dial wheel 31 is rotated so that the second screw 30 coaxially connected to the dial wheel 31 drives the slider 29 to slide along the guide groove. At this time, the rotating seat 28 rotatably connected to the outer side of the slider 29 will move synchronously, so that the rotating seat 28 moves outward a certain distance, and the telescopic rod 2 set at the top of the driving bracket 7 is extended. The telescopic rod 2 will push the beam 1 to move, so that the swing frames 33 set at both ends of the beam 1 rotate along the rotating seat 28, and the position of the rotating seat 28 is manually adjusted synchronously until the bottom end of the swing frame 33 contacts the outer skin of the patient's mandible through the supporting assembly set by the fixed rod 12. The telescopic rod 2 is continued to be extended, and the telescopic rod 2 will continue to drive the push rod 27 in the supporting assembly to deflect inward, so that the push rod 27 presses down the patient's mandible to keep the patient in an open mouth posture.
