Description
Technical Field
The utility model belongs to the technical field of bolted connection, concretely relates to single face connecting bolt's specialized tool.
Background
The bolt is a cylindrical threaded fastener matched with a nut, and the fastener is composed of a head part and a screw rod and needs to be matched with the nut for fastening and connecting two parts with through holes. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection. The existing bolt is connected by the aid of threads and nuts, but the bolt and the self-locking nut are inconvenient to connect due to the fact that the bolt is located in a narrow space in the aerospace field, and although the self-locking nut can be connected by the aid of the self-locking rivet on the surface, the requirement on structural connection strength is high, and the self-locking rivet cannot effectively meet the requirement. Therefore, a single-sided connection type bolt has been developed for connection in a narrow space, but the bolt cannot be tightened using a conventional tool. Therefore, a special tool is urgently needed to be developed to solve the problem of bolt tightening.
