Abstract

The invention discloses an easily-twisted fastening nut and relates to the field of mechanical parts. Two planes are symmetrically formed on the two sides of a nut body of the easily-twisted fasteningnut; two side holes are symmetrically formed in the planes on the two sides of the nut body; cylindrical supporting rods are arranged in the centers of the side holes; and spherical flexible balls are fixed to the ends of the supporting rods. During using, a threaded hole of the nut body can be screwed on a bolt, then matching steel pipes are utilized to be inserted into the flexible balls and the supporting rods in the side holes, the force arm length is increased through the steel pipes, and the nut body is screwed on the bolt. A screwing tool for the easily-twisted fastening nut is simple,convenient to use and good in stability.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to an easy-to-twist fastening nut. Background technique [0002] A nut is a mechanical part that is screwed together with a bolt or a screw for fastening. The nut is connected with the nut and bolt of the same specification through the inner thread. Most of the existing nuts are simple in design, and a wrench is often needed to fasten the nut. For a nut with a larger size, a wrench with a larger size needs to be used, which is very laborious to operate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-to-twist fastening nut, by designing an elliptical cylindrical nut body, opening side holes on both sides of the nut body, and setting support rods and flexible balls in the side holes to facilitate insertion of steel pipes Then pull the nut body, the operation is more labor-saving. [0004] To achieve the above obj...
