Abstract
The invention provides a freely-detachable expansion screw. An expansion tube and a tapered butterfly nut are sequentially mounted on a screw rod, and a T-shaped guide corner angle of the tapered butterfly nut is inserted in a seam of a strip-shaped opening of the expansion tube and protrudes out to fix the tapered butterfly nut unable to rotate or shed. The freely-detachable expansion screw is put in a drilled hole, the screw rod is rotated for screwing, and the expansion tube is expanded under extrusion of the tapered butterfly nut to achieve an expansion fixing function. Since the nut is mounted reversely, only a screw cap of the screw rod can be exposed outside after fixation, the screw rod is easy to screw out when the expansion screw is detached, the expansion tube and the tapered butterfly nut are reserved in the hole, and the screw rod can be inserted for strengthening again when the expansion screw is needed next time. The tapered butterfly nut and the expansion tube can be combined into an integral product for independent sell. The expansion screw is freely detachable, reusable and simple in production process.
