Abstract
The utility model is suitable for the technical field of a screw, and provides a pull-bursting type ceiling and pendant screw, which comprises a stud, an expansion tube, a main screw head and a cone-shaped ejection part. The stud is arranged on one of the cone-shaped ejection part and the main screw head and is screwed with the other of the cone-shaped ejection part and the main screw head, the expansion tube is sleeved on the stud, and part of the main screw head part extends into the expansion tube. When the main screw head and the cone-shaped ejection part are screwed tightly, the inner wall of the lower end of the expansion tube is ejected by the cone-shaped ejection part, so that the lower end of the expansion tube is gradually expanded outwards. The main screw head and the cone-shaped ejection part can be conveniently screwed with a mechanical tool, pressure can be easily applied on the expansion tube for expansion, and expansion can be achieved in case of high density or high grade at an application end. Moreover, the pull-bursting type ceiling and pendant screw is easy to install and is time-saving, labor-saving, safe and stable. Since the cone-shaped ejection part is provided with an ejection surface with grooves and bulges arranged at intervals, residues produced in drilling at the application end can be accommodated, the contact friction can be increased, and better fastening effect can be achieved.
