Propelled mark injection gun

Abstract

The invention discloses a propelled mark injection gun, which comprises a tube body, wherein one end of the tube body is provided with a trumpet-shaped positioning port, and the other end of the tube body is connected with a valve; the valve is also connected with a compressed gas tank and a switch for controlling the compressed gas tank; the inner side of the tube body is provided with a firing pin, and the firing pin can slide in the tube body; the lower end of the firing pin is provided with a hemispheroidal working end face and is rigid and smooth; the upper end of the firing pin is tightly matched and provided with a sealing ring so that the firing pin can slide in the tube body under the gas pressure action of the compressed gas tank; the middle part of the inner wall of the tube body is provided with a brake; and the side circumference of the firing pin is also provided with a spring so that the firing pin can slide to and fro in the tube body under the gas pressure of the compressed gas tank and the action of the spring. The propelled mark injection gun has the advantages of novel structure, convenient operation and process observation, high injection efficiency, suitability for rotary drilling mark injection operation and the like.

Description

technical field [0001] The invention relates to an auxiliary implant tool for living body markers, in particular to a push-type marker injection gun. Background technique [0002] Cephalopods are widely distributed along the coast and are a traditional fishery species with high economic value. Due to overfishing and ecological deterioration, since the 1970s, there have been successive declines. In the 1980s, it was reported that Li Xingjie et al. conducted preliminary research on the resources and multiplication of squid squid, while there were reports on the biology and breeding of squid abroad. In the process of domestication and breeding of wild squid mansoni, after two to three generations of domestication and breeding, wild squid began to adapt to the artificial domestication environment, so as to achieve the purpose of large-scale production, and some progress has been made, laying the foundation for multiplication and release. base. In order to restore the natural ...
