Simple device for quick unhooking

A simple device for quick unhooking comprises a clamping ring, a mounting hole is horizontally formed in the open end of the clamping ring in a penetrating mode, a powerful magnet is arranged at the outer end of the mounting hole in one side, a mounting groove is formed in the outer end of the mounting hole in the other side, and a pin is movably arranged in the mounting groove. One end of the pin penetrates through the mounting hole and can be fixed to the powerful magnet in a magnetic attraction mode, and a pull rope penetrating out of the mounting groove is arranged at the other end of the pin. Compared with manual climbing unhooking, the device disclosed by the utility model is simple to operate, and the problems of low efficiency, large potential safety hazard of climbing and tedious unhooking caused by manual climbing unhooking are avoided; compared with the lifting unhooking of a lifting vehicle, the problems of limitation of a construction site and limitation of the construction range of the lifting v
