Handheld hole puncher for chick embryo eggshell

Abstract

The invention discloses a handheld hole puncher for a chick embryo eggshell. The hole puncher comprises a bottom plate, an egg, a fixing assembly, a punching assembly and a reset assembly, a fixing column is fixedly connected to one side of the upper end face of the bottom plate, a sliding seat is slidably connected to the fixing column, fixing rotary knobs used for fixing the sliding seat are arranged on the two sides of the sliding seat, and a mounting plate is fixedly connected to one side of the sliding seat. Through the arrangement of a placing cylinder and a sealing ring arranged at an upper end opening of the placing cylinder, the egg can be conveniently placed, meanwhile, through a connecting buckle arranged in a drawing pipe, after the egg is placed, a drawing rod and a piston block can be pulled out by drawing a drawing handle, and after being pulled out, the drawing rod is hung and buckled in a groove in the side of a groove plate. A negative pressure state can be formed in a fixing barrel, an adsorption effect on the egg is achieved, the situation that the egg shakes during perforating is effectively avoided, and the arranged sealing ring has a sealing effect and can prevent the egg from being collided during placement.

Description

technical field [0001] The invention relates to the technical field of punchers, in particular to a hand-held eggshell puncher for chicken embryos. Background technique [0002] Eggs are the eggs laid by hens. After fertilization, chicks can be hatched. There is a hard shell on the outside, and there are air cells, egg white and yolk inside. Eggs contain a lot of vitamins, minerals and proteins with high biological value, and are one of the foods that humans often eat; in the production of biomedicine, chicken embryo eggs need to be inoculated to allow the virus to reproduce in the embryo eggs, and pass through after the reproduction is completed. Vaccines are made by different processes such as inactivation and freeze-drying. When inoculating embryonated eggs, because the inoculation needle is relatively small, it is impossible to directly penetrate the eggshell, so it is necessary to punch holes in the eggshell first, and then insert the inoculation needle for virus inocu...

Problems solved by technology

[0003] However, when the existing embryonic egg puncher punches embryonic eggs, it generally places the egg in a circular groove to punch holes. The egg is easy to shake when punching holes, which will cause the egg to break. At the same time, when the existing egg puncher punches the egg, it is inconvenient to control the force applied, which greatly increases the probability of punching failure. Based on the above problems, we provide a hand-held chicken embryo eggshell puncher to solve the above-mentioned problems
