Problems solved by technology
[0003] However, the existing syringes have the problems of poor practicability and poor injection stability. Because the existing syringes use the direct manual push of the piston rod to complete the injection, there is a large friction between the piston and the injection cavity, and the instant the injection is just started Larger force is needed to overcome the static friction force, which may lead to errors in the injection volume due to excessive force

The invention has the characteristics of strong practicability and smooth injection process.
Description
technical field [0001] The invention relates to the technical field of syringes, in particular to a cosmetic injection device. Background technique [0002] A syringe is a device that uses a needle to withdraw or inject gas or liquid from the body. It has the characteristics of simple structure and high injection precision. The common materials are glass and plastic, and it is widely used in medical treatment, beauty salons and quantitative chemical analysis and other fields. [0003] However, the existing syringes have the problems of poor practicability and poor injection stability. Because the existing syringes use the direct manual push of the piston rod to complete the injection, there is a large friction between the piston and the injection cavity, and the instant the injection is just started Larger force is needed to overcome the static friction force, which may lead to errors in the injection volume due to excessive force. Therefore, it is necessary to design a co...
