Abstract

The invention discloses a combined bolt which comprises a head, a combined screw and a working nail end, wherein one end of the combined screw is fixedly connected with the head, and the other end of the combined screw is in assembly connection with the working nail end; the combined screw comprises a plurality of sections of cylinders with threads; the cylinders are in assembly connection; and one end of the working nail end is connected with the tail cylinder, and the other end of the working nail end is conical. In this way, the traditional bolt structure is replaced, the screw length can be adaptively adjusted, the simple drilling action can be carried out by a conical head in inconvenient situation, and the combined bolt is powerful in function, wide in application range and convenient and easy to operate.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a combined bolt. Background technique [0002] Bolts are indispensable connectors in the assembly of various parts. They cooperate with nuts to connect parts, and the connection form is a detachable connection. [0003] Generally, bolts have specifications and sizes, and the production of mechanical parts produces corresponding assembly positions according to the specified sizes. But there are always some exceptions, such as the bolt length is not enough to connect two parts; temporarily need to use bolts to make holes in the mounting surface and so on. It makes people feel that the standard bolts are inconvenient to use. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a combined bolt, which can lengthen the screw rod, has a simple drilling function, and is convenient and quick to use. [0005] In order to solve th...
