piercing device

Abstract

The present disclosure provides an ear piercing device, comprising: a base shell, on which is configured a first installation cavity extending parallel to the ear stud piercing direction; an integrally formed ear stud piercing shell, used for assembling the ear studs An assembly or an ear stud, which is fixedly connected in the first installation cavity through a third snap button, the ear stud puncture housing has a push rod guide cylinder embedded in the first installation cavity, and the puncture assembly is at least partially located in the first installation cavity. The push rod guides the inside of the barrel and the stud piercing housing and the cavity bottom wall of the first installation cavity jointly form a clamping position for the piercing assembly. According to the ear piercing device of the present disclosure, the piercing assembly and the ear stud piercing shell can be quickly assembled into one body, and then snap-fitted with the base shell to realize reliable positioning of the piercing shell. The assembly process of the ear piercing device is simplified, the assembly efficiency is improved and the manufacturing cost of the device is reduced.

Description

technical field [0001] The disclosure belongs to the technical field of accessories auxiliary installation equipment, and in particular relates to an ear piercing device. Background technique [0002] The ear-piercing devices in the prior art mainly include two types, one is a fully disposable ear-piercing device driven by manual pressure. This type of device can effectively avoid cross-infection and is more hygienic because it belongs to the fully-disposable type. Putting the studs through the earlobe with finger strength requires the operator to have more guts and more skillful techniques; one type is a reusable spring-driven ear piercing gun, which is used with disposable earrings, and its The power of the spring is used to push the stud through the earlobe, and the operation is simple and fast. However, the ear piercing gun is reused, and there is a hidden danger of cross-infection. [0003] Japanese patent JP2006158669A specifically discloses a spring-driven fully disp...

[0002] The ear-piercing devices in the prior art mainly include two types, one is a fully disposable ear-piercing device driven by manual pressure. This type of device can effectively avoid cross-infection and is more hygienic because it belongs to the fully-disposable type. Putting the studs through the earlobe with finger strength requires the operator to have more guts and more skillful techniques; one type is a reusable spring-driven ear piercing gun, which is used with disposable earrings, and its The power of the spring is used to push the stud through the earlobe, which is simple and fast to operate, but the ear piercing gun is reused, and there is a risk of cross-infection

[0003] Japanese patent JP2006158669A specifically discloses a spring-driven fully disposable ear piercing device, but it is assembled from a plurality of scattered parts, and the assembly between the parts is realized by screw (screw) connection, which leads to Ear piercing devices are extremely inefficient to assemble, resulting in high device manufacturing costs
