Abstract

An automatic detaching structure for a hook device includes a hook, a power unit, a tongue plate and an off-hook member. The power unit comprises a motor which is remote-controlled. The motor has a shaft. A first transmission transforming mechanism and a first gear are provided on the shaft. The first transmission transforming mechanism and the first gear mesh with a second transmission transforming mechanism and a second gear, respectively, to link a rotating lever and a transmission lever. The rotating lever links the tongue plate in an open status, while transmission wheels on the transmission lever pull the off-hook member to detach a rope of a cargo from the hook.
