Device for producing complete empty eggshell

Abstract

The invention relates to a device for producing a complete empty eggshell. The device is characterized by comprising a horizontal base plate, an upper seat body and a lower seat body, wherein an upright post which is upwards and vertically extended is fixed on the horizontal base plate, and the upper seat body and the lower seat body are correspondingly arranged on the upright post; the lower seat body is fixed at the middle lower part of the upright post, the upper seat body is correspondingly and moveably sheathed on the upright post above the lower seat body, and the upper seat body can slide up and down along the upright post; the middle parts of the opposite faces of the upper seat body and the lower sat body are correspondingly provided with egg cutting concave cavities in a concave way, and the bottoms of the two concave cavities are correspondingly provided with central through holes lengthwise and vertically arranged. The device also comprises hand push rods which are in slide fit in the central through holes of the upper seat body and the lower seat body, and needle heads are correspondingly inserted in the middle parts of the inner end heads of the hand push rods; and positioning and reset mechanisms are arranged between the corresponding hand push rods and the seat bodies. A vertical raw egg can be accurately clamped by the upper seat body and the lower seat body of which the opposite faces are correspondingly provided with the egg cutting concave cavities, and the upper and lower needle heads which are matched with each other are used for accurately piercing the eggshell, thereby preventing the raw egg manually held and nipped from being broken during the process of piercing, and guaranteeing the process of piercing is accurate, safe and reliable.

Description

technical field [0001] The invention relates to a device for making complete empty eggshells. Background technique [0002] In order to make eggshell handicrafts or experiments, it is necessary to take a complete empty eggshell. The usual method is: hold the raw egg tightly in one hand, and hold a needle in the other hand, and use the needle to pierce holes on both ends of the raw egg , and then use the hole at one end to blow air into the egg, so that the egg yolk and egg white in the raw egg flow out through the hole at the other end to obtain a complete empty eggshell. The disadvantages of this method of extracting eggshells are: 1. Because the eggshells are fragile, during the process of pricking holes, careless force can easily pinch the raw eggs; 2. Because the surface of the eggshells is smooth, it is difficult to locate the holes, It is difficult for the two holes to be located on the long axis of the eggshell at the same time; three, the inside of the empty eggshel...
