Embodiment Construction

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0013] see figure 1 , the embodiment of the present invention includes:

[0014] A bolt with an auxiliary screw head is characterized in that it includes: a screw head 1, an auxiliary screw head 2, and a screw rod 3, the screw head 1 is a hexagonal screw head with a regular hexagonal cross section, and the screw head The bottom of the head 1 is connected and fixed to the auxiliary screw head 2, and the bottom of the auxiliary screw head 2 is fixedly connected to the screw 3. The screw 3 is a cylindrical structure, a...

Abstract

The invention discloses a bolt with an auxiliary screw head. The bolt comprises a screw head, the auxiliary screw head and a screw, wherein the screw head is a hexagonal screw head with an orthohexagonal cross section, the auxiliary screw head is connected and fixed to the bottom of the screw head, the screw is fixed and connected to the bottom of the auxiliary screw head, and the screw is of a cylindrical structure; a thread is arranged on the outer surface of the screw, the vertical center axes of the screw head, the auxiliary screw head and the screw are located on the same straight line, and the auxiliary screw head is a hexagonal screw head and is smaller than the screw head. In this way, wrenching stress can be dispersed through the auxiliary screw head, wrenching is assisted by the auxiliary screw head when being conducted at the position of the screw head, wrenching stress is dispersed, wrenching is easier, and practicality is high.

Description

technical field [0001] The invention relates to the field of fixing components, in particular to a bolt with an auxiliary screw head. Background technique [0002] Bolt is a kind of mechanical parts. It is a cylindrical threaded fastener with a nut. It is a type of fastener composed of two parts, the head and the screw. It needs to be matched with the nut to fasten the connection between two For parts with through holes, at present, the bolt structure on the market is similar, most of which are solid structures. The wrench is used to clamp the screw head and then screw it. There are few stress points on the screw head, so it is not easy to operate. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a bolt with an auxiliary screw head, which can distribute the wrenching force through the auxiliary screw head, and use the auxiliary screw head to perform auxiliary wrench work while wrenching at the screw head. T...
