Problems solved by technology

[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

Abstract

The invention discloses a double-end screwing bolt which comprises a screw head and a screw, wherein the screw head is a hexagonal screw head with a regular-hexagon transverse cross section; the bottom of the screw head is fixedly connected with the screw; the vertical center axis of the screw and the center axis of the screw head stay on the same straight line; the screw comprises a thread part and a screwing part; the thread part is of a cylindrical structure with thread on the outer surface; the screwing part is connected with the screw bottom below the thread part; the screwing part is of a hexagonal prism structure with a regular-hexagon transverse cross section; the thread part and the screwing part form an integrated structure. Through the way, the two ends of the bolt disclosed by the invention can be screwed; when the screw head is screwed, the screwing part at the screw bottom assists the screwing operation, thus the screwing stress is dispersed, the screwing is easier, and the practicability is higher.

Description

technical field [0001] The invention relates to the field of fixing components, in particular to a double-ended screwable bolt. 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 capable of double-head wrenching, which can perform double-head wrench operation. While wrenching at the screw head, the wrench part at the bottom of the screw rod is used to assist the wrench work. The force of t...
