Embodiment approach
[0083] Embodiment: the pitch P=1.54mm of the first return spring 3, the total number of turns n=19±0.5, the effective number of turns n 1 =17.5±0.5, total length 27.5±1mm; pitch P of the second return spring 3=1.32mm, total number of turns n=28±0.5, effective number of turns n 1 =26.5±0.5, the total length is 36±1mm; the weight of the counterweight 9 is 0.003kg; in the initial state, that is, when the injection needle 4 is in the stowed state, the floating gap between the counterweight 9 and the excitation sleeve 6 is 5-7mm. After repeated tests, in this embodiment, when the injection needle 4 moves to the maximum distance, the thimble 8 can push out the catgut 2 .
