Abstract

A fast dismantling device comprises two C-shaped fitting rings, two shaft bolts, two pivots, two dial rods, and a connection rod. The fitting rings are provided with a through hole and are fitted over an outer tube. The shaft bolts include a head and a shank which is received in the through hole of the fitting rings. The pivots are disposed at the free ends of the shanks of the shaft bolts. The dial rods comprise a cam portion which is formed of two actuation pieces. The shaft bolts are disposed between the two actuation pieces. The actuation pieces are provided with a through hole for receiving the pivot. The connection rod is connected at both ends thereof with the dial rods. As the connection rod is wrenched to actuate the dial rods, the fast dismantling device is capable of fastening or unfastening simultaneously two pairs of inner and outer tubes.
