[0107] The medicine pushing plate 710 and the push rod 720 are arranged to push the medicine liquid during sliding, so that the medicine liquid can move normally and be sprayed out through the spray head 440 .

[0108] Working method of the utility model:

[0109] When in use, the expansion device 600 is placed inside the patient's oral cavity, and the squeezing force on the expansion rubber 640 is released, so that the expansion rubber 640 expands the patient's oral cavity under the elastic force of the spring 630, and then the extension rod 410 is controlled by the hand-held handle 430 according to the position of the patient's affected part to prevent the extension rod 410 from rotating, and then the polygonal column 520 is rotated so that the polygonal column 520 drives the threaded sleeve 510 to rotate, so that the threaded sleeve 510 drives the extension rod 410 to move under the action of the thread, so that the extension rod 410 adjusts the position of the spray head 440 in the patient's oral cavity, and then the extension rod 410 is controlled to swing and rotate, so that the extension rod 410 drives the spray head 440 to move to the affected part of the patient's oral cavity;

[0110] Then, the squeezing column 330 is pushed to move along the inclined through hole 320, and the diversion pipe 220 is squeezed when the squeezing column 330 moves to adjust the diversion amount of the diversion pipe 220;

[0111] To spray the medicine, push the medicine pushing plate 710 to move, so that the medicine pushing plate 710 pushes the medicine through the diversion pipe 220 to flow into the liquid guide channel 420, and is sprayed to the patient's affected part through the spray head 440. When it is necessary to push the medicine again, open the blocking valve 230, then pull the medicine pushing plate 710 away from the diversion pipe 220, then close the blocking valve 230, and then squeeze the medicine pushing plate 710 again, so that the medicine pushing plate 710 sprays the liquid medicine through the spray head 440.
