The invention discloses a hook-type traction conversion device, pertaining to the field of platform traction and conversion.The hook-type traction conversion device comprises an installation base. One end of the installation base is fixed on an airdrop platform and the other end of the installation base is provided with a blind hole. One end of a separation part is arranged in the blind hole. The hook-type traction conversion device further comprises a rotary hook and a transmission mechanism. One end of the rotary hook is hinged onto the installation base and the other end of the rotary hook extends towards the direction of the blind hole, which is used for limiting movement of the separation part in the blind hole. The transmission mechanism is connected with the rotary hook and controlling the rotary hook to rotate. The hook-type traction conversion device has following beneficial effects: the transmission mechanism is a linkage mechanism; when traction and conversion are not performed, a second driven rod and a third driven rod are on the same straight line; the straight line is vertical to the connecting line between a hinged point of the third driven rod on the rotary hook and a hinged point of the rotary hook on the installation base so as to form dead point protection; the hook-type traction conversion device can keep connection between the separation part and the airdrop platform when the separation part is not subjected to traction and conversion; and the separation part is driven by the linkage mechanism to separate from the airdrop platform.
