The invention provides an automatic hooking device used for lifting a movable pulley. The automatic hooking device comprises a fixed pulley assembly, a movable pulley assembly and a hook assembly, wherein the fixed pulley assembly comprises a fixed pulley and a fixed pulley frame; the movable pulley assembly comprises a movable pulley and a movable pulley assembly frame; the hook assembly comprises hooks and tension springs; the hooks are symmetrically hinged to two sides of the fixed pulley frame; the tension springs are located between the hooks and are connected with the hooks on the two sides; a panel is arranged at the upper end of the movable pulley frame; the panel directly impacts to open the hooks on the two sides and enter the hooks; meanwhile, the hooks on the two sides are automatically closed under the action of the tension springs, so that the movable pulley is automatically hooked. Through the automatic hooking device, the hooks with guide cants and an approach switch are arranged, so that the panel on the movable pulley directly impacts the guide cants of the hooks; the hooks are opened under the action of the lateral force and are automatically closed under the action of the tension springs, so that the movable pulley is automatically hooked; the complexity and inaccuracy of manual hooking are avoided; the automatic hooking device is compact in design structure, is light and handy and has good using effect.
