The bayonet symmetrical arrangement referred to herein means that the bayonet is arranged in sets (at least two) on the inner wall of the inner layer of the sleeve, and the bayonets in each set are axisymmetric with respect to the inner layer of the sleeve.
Preferably, the three buckles are respectively arranged at the lower part, the middle part and the upper part of the piston rod; the bayonet is arranged at the position of the other end edge of the inner layer of the sleeve.
The lower part, the middle part and the upper part of the piston rod are buckled, and when the piston rod is respectively fixed to the bayonet in a matched mode, the piston is respectively positioned at one end part, the middle part and the other end part in the inner layer of the sleeve.
Preferably, the sleeve is made of transparent materials.
Preferably, a graduated scale is drawn on the inner wall of the sleeve along the length direction of the sleeve.
The structure of the arc-shaped elbow makes the end of the scraping device staggered with the extension direction of the outer wall of the sleeve as the grab handle, thereby being convenient for beginners to keep a certain angle in the scraping process. The plastic pipe reduces the manufacturing difficulty, and can visually represent whether leakage exists in the negative pressure suction process through elastic change.
The injury to the human body during the scraping can be avoided through the smooth edge or the annular rubber sleeve.
The symmetrical bayonets and the buckles can provide certain functions of preventing inclination and rotation for the piston, and the failure of the piston in the suction operation process is avoided by matching with the special shape of the scraping device.
The lower part, the middle part and the upper part of the buckle on the piston rod are arranged, so that a user can adjust different negative pressure according to requirements through different pushed hand feels. And the negative pressure adjusting degree can be conveniently observed from the outside.
The utility model has the advantages that the negative pressure can be simply and conveniently regulated to replace the force of the traditional scraping plate, the force during use is normalized, and a certain angle is formed between the negative pressure and the stressed skin during use, so that the negative pressure type skin scraping plate can be conveniently and better used by people without relevant medical knowledge.
