Description

technical field [0001] The present invention relates to a reusable pen injector. Background technique [0002] Diabetic patients need an insulin syringe that can be carried at any time and is easy to use. There are related injection products on the market now. Most of the syringes use the principle of screw drive, which can achieve the purpose of advancing the push rod through rotation. [0003] Most of the injection pens are used in the same way. First, the desired scale is rotated by turning the screw at the end, and then the needle at the other end is inserted into the part of the body to be injected, and then the push handle at the end is pushed to inject the liquid medicine. [0004] For example, the Chinese patent CN101829381B authorized on 2015.4.25, the invention title is "A kind of adjustable metering insulin injection pen" patent; it has the following problems: [0005] 1. The main drive screw drum and the casing are integrated, which is not conducive to smooth in...
