[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A three-dimensional rubber dam for children's oral cavity comprises a rubber dam body, one end of the rubber dam body is provided with an opening, the inner wall of the opening is symmetrically provided with two rows of positioning points, two cross-arranged adjusting rods are rotatably connected in the opening via a rotating shaft, one end of the two adjusting rods away from the rotating shaft abuts against the inner wall of the opening, an adjusting bolt is rotatably inserted into one of the adjusting rods, one end of the adjusting bolt is threadedly sleeved with a threaded sleeve, one end of the threaded sleeve is connected to another adjusting rod via a connecting rod, and the two ends of the connecting rod are rotatably connected to the threaded sleeve and the adjusting rod respectively.

[0008] Preferably, a rubber support ring is fixedly sleeved on one end of the rubber dam body close to the opening.

[0009] Preferably, the number of positioning points in each row is 12.

[0010] Preferably, an end of the adjustment rod away from the rotating shaft is fixedly connected with an arc pad.

[0011] Preferably, one end of the adjusting bolt located in the threaded sleeve is fixedly connected to a limiting block.

[0012] Preferably, the rubber dam body is in a conical shape.

[0013] Beneficial effects:

[0014] 1. The threaded sleeve can be driven to move by rotating the adjusting bolt, and the two adjusting rods can be driven to rotate by the connecting rod, so that the angle between the two adjusting rods changes, thereby changing the inner diameter of the opening. In the utility model, the oral rubber dam can be adjusted accordingly according to the inner diameter of the child's oral cavity through the setting of the adjusting structure, thereby effectively improving the use effect of the rubber dam;

[0015] 2. By setting the positioning points, it is convenient to drill holes according to the position of children's teeth. At the same time, the setting of the arc pad can increase the support range of the adjusting rod, and the limit block can prevent the adjusting bolt from falling off from the threaded sleeve.
