Abstract

The invention relates to a flight dropper for overcoming the defects that a well-known flight dropper without a rope rewinding member has difficulty in rope rewinding to influence repeated use and safe rescue. The flight dropper provided by the invention has the principle that a one-way rotating member is arranged between a rope winder and a crankshaft; when the rope falls, the rope winder revolves and drives the crankshaft to rotate, and the crankshaft revolves and drives a piston rod to operate; and when the rope is rewound, the rope winder rotates, but the crankshaft does not revolve, and a piston does not generate resistance to the crankshaft since the crankshaft does not revolve. By the one-way rotating member arranged between the rope winder and the crankshaft, a user can conveniently and rapidly rewind the rope, and the invention is rapid and repeated to use and favorable to safe rescue.
