[0005] Preferably, the upper portion of the top cover is a cover body that can be flipped open, and a pointed tube is provided at the bottom of the top cover. When the top cover is installed on the rotating drum, the pointed tube pierces the top of the ointment replacement core and enables the medicine in the ointment replacement core to flow out through the pointed tube under the action of squeezing, thereby reducing excessive contact of the ointment with air for oxidation, which affects the shelf life of the ointment.

[0006] Preferably, a circular boss is provided at the bottom of the rotating cylinder, and a circular groove is provided at the bottom of the guide cylinder, and the circular boss is placed in the circular groove to achieve rotational fit.

[0007] Preferably, the ointment replacement core body is a corrugated plastic tube, which is convenient for contracting upward during the extrusion process to discharge the ointment.

[0008] Preferably, a pair of vertical slots of the guiding cylinder are symmetrically arranged, and a pair of clips are symmetrically arranged at the bottom of the push rod to ensure that the push rod can rise smoothly to extrude the ointment replacement core.

[0009] Preferably, the bottom of the push rod is provided with a disc, and a pair of horizontal convex columns are symmetrically arranged outside the disc as a pair of clips. The outer diameter of the disc matches the inner diameter of the rotating cylinder to prevent the push rod from shaking during use.

[0010] The beneficial effects of the present utility model: The traditional ointment is replaced by an ointment replacement core, and the ointment is quantitatively packaged to control the dosage of the ointment, avoiding the ointment exceeding the shelf life. Moreover, in cooperation with the extrusion device, single-handed operation is realized. In the face of special situations where single-handed use is required, only one hand needs to dial the dial teeth, and the push rod squeezes the ointment replacement core upward to realize single-handed extrusion of the ointment for applying medicine to the affected area.
