Abstract

The invention discloses a bolt easy to pull and screw. The bolt easy to pull and screw comprises a first threaded rod. The top of the first thread rod is fixedly connected with the bottom of a first thread head. A second groove is formed in the middle of the top of the first thread head. The bottom of a first groove extends into a fourth groove formed in the first thread rod. A first through hole is formed in one side face of the first thread head. The first through hole is fixedly connected with a second through hole formed in a second thread rod through a first plug pin. The top of the second thread rod is fixedly connected with the bottom of a second thread head. According to the bolt easy to pull and screw, by arranging the first groove, the first plug pin and the second through hole, a fixing effect on the second thread rod is achieved; by using a cross-shaped disc and a connecting block in cooperation, the probability that the sliding block falls off is lowered, and pulling and screwing are extremely effortless; the number of force-bearing points of the connecting block on the second thread head is increased, so that operation is extremely easy; and the structure is simple, using is convenient, and the structure is novel.

Description

technical field [0001] The invention relates to the technical field of metal products, in particular to an easy-to-wrench 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 Parts with through holes, at present, the bolt structure on the market is similar, most of them are solid structures, and the screwing method is to clamp the screw head through the connecting block, and then screw it. In the prior art, the screw head of the existing bolt Most of the head designs are the same. When using the connecting block to wrench, the connecting block will often slip because there is no slot on the screw head to block the connecting block. There are certain limitations, and the wrench is also very difficult. The connecting block is on the screw head. Less stress, it is no...
