[0028] When in use, first pinch the outer sides of the two lower jaw blocks 701 with one hand, then rotate the circular block 501, the circular block 501 drives the rotating column 502 to rotate, the rotating column 502 drives the sliding ring 505 and the pushing plate 507 to rotate together through the limit of the sliding block 506, when the pushing plate 507 is aligned with the rectangular opening on the fixed plate 508, the elasticity of the trigger spring 503 is released, the trigger spring 503 pushes the sliding ring 505, the sliding block 506 and the pushing plate 507 to move forward along the sliding groove 509, and the pushing plate 507 pushes the T-shaped column 601, the rubber ring 602 and the rack 603 to move forward together The rack 603 drives the limiting gear 604 to rotate, and the T-shaped column 601 drives the entire automatic saliva suction mechanism 3 and the supporting angle adjustment mechanism 2 to move outward together. When the fingers feel the thrust given by the outward extension of the lower jaw block 701, the entire size adaptive adjustment mechanism 1 is placed in the center of the patient's lower mouth and then let go. Then the two lower jaw blocks 701 drive the automatic saliva suction mechanism 3 and the supporting angle adjustment mechanism 2 to move outward together. When the lower jaw block 701 is in close contact with the inner side of the patient's lower gums, the size adaptive adjustment mechanism 1 automatically adjusts the width of the device according to the size of the patient's mouth.

[0029] Then, the support and adjustment of the patient's oral cavity is performed according to the needs, and the worm 202 is rotated. The worm 202 drives the worm wheel 203 and the screw 204 to rotate together. The screw 204 drives the lifting column 205 to move upward, and the lifting column 205 pushes the upper jaw block 208 to lift until the upper jaw block 208 and the lower jaw block 701 reach a suitable angle to support the patient's oral cavity; then, the medicine is applied to the patient's tooth socket after tooth extraction, and the nut 1005 is first rotated to release the nut 1005 from squeezing the injection needle 1006, and then the injection needle 1006 is taken out of the ring 1004 and a certain amount of medicine to be applied is absorbed, and then the direction of the ring 1004 is adjusted according to the position of the tooth socket, and the motor 2 902 is started. The motor 2 902 drives the rotating table 903 to rotate, and the rotating table 903 drives the semicircular gear 904 and the entire drug delivery system. Component 10 rotates together, that is, the ring 1004 is driven to rotate. When the semicircular gear 904 is in a straight line with the alveolar socket, the motor 2 902 can be stopped, and then the ring 1004 is moved upward or downward according to whether the alveolar socket is above or below. The ring 1004 drives the U-shaped frame 1002 and the friction block 1003 to slide along the arc groove, and the U-shaped frame 1002 drives the adjusting gear 1001 to rotate around the semicircular gear 904. When the center of the ring 1004 is in the same straight line with the alveolar socket, the injection needle 1006 is reinserted into the ring 1004, and then the injection needle 1006 is pushed forward so that the medicine outlet of the injection needle 1006 is placed on the alveolar socket, and then the nut 1005 is turned again to fix the injection needle 1006, and then the piston 807 of the injection needle 1006 is pushed to push the medicine to the alveolar socket.

[0030] If it is necessary to absorb the saliva secreted by the patient, first push the convex block 702 to move the convex block 702 along the convex groove 704, and the convex block 702 drives the pipette 808, the columnar tube 802 and the rectangular box 803 to move together until the pipette 808 moves to the saliva secretion position, and then start the motor 804, the motor 804 drives the U-shaped block 805 to rotate, and the U-shaped block 805 drives the connecting rod 806 and the piston 807 to reciprocate up and down. When the piston 807 moves upward, suction is generated on the limiting ball 1 814 and the limiting ball 2 816. The limiting ball 1 814 is forced to move inward, and the spring 1 813 contracts, so that the pipette 808 The interior of the L-shaped block 801 is connected, and the limiting ball 816 is limited by the cross groove 811 and remains stationary, thereby sucking the saliva into the L-shaped block 801 through the suction tube 808. When the piston 807 moves downward, a thrust is generated on the limiting ball 814 and the limiting ball 816. The limiting ball 816 moves outward under the force, and the spring 815 is stretched, thereby making the liquid outlet hose 809 and the interior of the L-shaped block 801 connected. The limiting ball 814 is limited by the cross groove 811 and remains stationary, thereby pushing the saliva in the L-shaped block 801 out through the liquid outlet hose 809, thereby realizing automatic suction and discharge of the saliva secreted by the patient.
