Fastening kit and combined expanding device utilizing fastening kit
A fastening kit comprises a bolt and a nut. The bolt comprises a head part and a screw. The screw comprises a first end fixedly connected with the head part, a second end connected with the nut in a threaded mode, and an elastic energy storage component combined with the two ends. A deformation structure corresponding to threaded connection acting force is formed on the portion, between the first end and the second end, of the elastic energy storage component. The fastening force of the fastening kit can be effectively maintained after screwing and fastening are achieved in place through elastic deformation of the fastening kit, and fastening failures caused by vibration, heat expansion and cold contract of the environment after fastening is achieved in place are counteracted. Meanwhile, the single-directional screwing-in structure of the head part of the bolt is matched with the smooth top of the nut so that the fastening structure can not be deconstructed, fastening reliability can be effectively improved, and the fastening kit can not be detached without a destructive means. The invention further provides a combined expanding device utilizing the fastening kit.
