Since the anti-slip strip (112) at the bottom of the traction strip (111) contacts the eyelids, the contact friction is increased, so that the two traction strips (111) can open the upper and lower eyelids of the patient. At the same time, the medicine application tube (801) drives the conical dropper (802) to approach the patient's eyes, and then squeezes the eye drop bottle so that the medicine can drip into the patient's eyes through the dropper (802), without having to open the eyelids by hand to apply the medicine; After the medication is applied to the patient, the eye drop bottle is removed, so that the pressing plate (9) and the medication tube (801) are no longer under pressure, and the blocking plate (803) is supported by the elastic force of the second spring (804), so that the blocking plate (803) drives the pressing plate (9) to move upward through the medication tube (801), so that the drip nozzle (802) can be away from the eye. In the process of the pressing plate (9) moving upward, the two support bars (116) can be pulled, so that the two support bars (116) drive the two horizontal plates (115) to move closer to each other, and the horizontal plate (115) drives the traction bar (111) to move through the vertical plate (114) and the fixed column (113), so that the two traction bars (111) are closer to each other and return to the initial position, and then the connecting buckle (14) is opened to separate the two straps (13) so that the positioning device can be removed from the patient's eye.
