The process that bait was extruded in the downward removal of piston cylinder telescopic link is intermittent type nature, and when the piston cylinder telescopic link was motionless, buffer spring's buffering elasticity can be used in on the piston down, continues to promote downwards to piston assembly, makes bait can continue slowly to extrude, avoids appearing bait and supplies the phenomenon absolutely.
Preferably, the bait extrusion head is arranged obliquely outwards from top to bottom. The bait extrusion head is obliquely arranged to facilitate extrusion of the bait.
Preferably, the upper end of the bait storage barrel is provided with a hopper corresponding to the feed hole. The hopper is convenient for adding bait.
Preferably, the upper end of the feeding cylinder is provided with a support, and the piston cylinder and the bait storage cylinder are both arranged on the support. The setting of support is convenient for the installation of piston cylinder and bait storage section of thick bamboo.
Preferably, a fastening screw is connected between the one-way cover plate and the bait outlet, and a pre-tightening spring is arranged between the nut end of the fastening screw and the one-way cover plate. The pre-tightening spring plays a certain pre-tightening role on the one-way cover plate, so that the one-way cover plate covers the end face of the bait outlet nozzle and has good sealing performance.
Preferably, a fastening screw is connected between the one-way valve plate and the bait-squeezing piston, and a pre-tightening spring is arranged between the nut end of the fastening screw and the one-way valve plate. The pre-tightening spring plays a certain pre-tightening role on the one-way valve plate, so that the one-way valve plate covers the end face of the through hole, and the sealing performance is good.
