[0043] The dosing part 300 is installed on the side of the rotating shaft groove 103, and the dosing part 300 includes a mounting shaft 301, a through hole 302, a cylindrical barrel 303 and a medicine barrel 307. The side of the rotating shaft groove 103 is coaxially fixed with one end of the mounting shaft 301, and the through hole 302 is radially opened on the side of the mounting shaft 301. The cylindrical barrel 303 that moves and rotates along the through hole 302 is arranged in the through hole 302, and the medicine barrel 307 is installed at one end of the cylindrical barrel 303, and the medicine barrel 307 contains medicine.

[0044] The utility model controls the two finger buckles 101 to pry the support plate 104 to open the target position in the patient's mouth, and uses the locking part 200 to lock the position of the two support plates 104. Since the cylindrical barrel 303 can rotate around the axis, the cylindrical barrel 303 can also rotate along the axis of the installation shaft 301, and the cylindrical barrel 303 can be extended and retracted along the length direction of the through hole 302. Therefore, the position of the medicine barrel 307 installed on one side of the cylindrical barrel 303 is adjusted by driving the cylindrical barrel 303, so that the position of the medicine barrel 307 is more accurately aligned with the affected area, thereby achieving efficient and more accurate medication.

[0045] As a further explanation of the present invention, see Figure 1 , 2 ,

[0046] The support rod 102 is bent at one side close to the support plate 104 , and the support rod 102 is bent toward a side close to the medication portion 300 .

[0052] Among them, the material of the card shaft 203 is a material with a large elastic coefficient, and the material can be PVC or rubber. The utility model ensures that when the operator drives the card shaft 203 into the buckle groove 202, the card shaft 203 can undergo a large deformation, and then smoothly engage with the buckle groove 202, thereby locking the angle between the two groups of support rods 102.

[0053] Among them, the cross-sectional shape of the sliding plate 204 is a square, and the cross-sectional shape of the inner surface of the sliding groove 205 is a square that matches the cross-sectional shape of the sliding plate 204. The utility model enables the sliding groove 205 to guide the sliding plate 204, so that the sliding plate 204 can only slide back and forth along the length direction of the sliding groove 205.

[0054] The contour of the arc rod 201 is an arc, and the center of the arc coincides with the axis of the rotating shaft groove 103 .

[0055] The cross-sectional shape of the buckle groove 202 is a water drop shape.

[0056] The utility model ensures that when the clamping shaft 203 is disposed in the buckle groove 202 , the clamping shaft 203 will not automatically fall out, thereby stably maintaining the angle between the two support rods 102 .
