Abstract
The invention discloses an anti-dropping fastener. The anti-dropping fastener comprises an outer fastener and an inner fastener, wherein the inner fastener comprises a screw and a stopping slide block, a threaded cylindrical groove is formed in the upper end of the outer fastener, and a plurality of slide rails vertically communicated with the groove are arranged at the bottom of the groove of the outer fastener; a circular hole is formed in the side face of the outer fastener, corresponds to the slide rails and communicated with the slide rails; and the screw is arranged in the groove and in threaded connection with the groove, the stopping slide block is arranged in the slide rails, one end of the stopping slide block is of a wedge-shaped structure connected with the bottom end of the screw, and a cone-shaped tip is fixed on the other end of the stopping slide block. The anti-dropping fastener is simple in structure, convenient and practical; due to the design and the use of a built-in fastening device, the fastening effect is greatly improved, and meanwhile, the service life of the fastener is effectively prolonged, so that the anti-dropping fastener can be not only applied to the daily life, but also applied to products which are to be assembled and fastened.
Description
Technical field
The present invention relates to a kind of securing means, especially a kind of loose-preventing fastening.
Background technique
In daily life, people often can utilize the securing meanss such as screw that object is fixed, still; common securing means does not have special fastening structure; screw thread or card only according to self fix object, thus, will cause working life and fastening effect not ideal enough.
In order to address the above problem, on the basis that fastening piece is fixed, increase again a securing means, will certainly improve widely fastening effect, also can increase the working life of fastening piece.
Summary of the invention
