Fork arm carrier die jacking device

The utility model discloses an ejecting device for a fork arm carrier die. Bottom plate, a jacking air cylinder is fixedly connected to the bottom plate. The two jacking air cylinders are symmetrically installed. The two jacking air cylinders are coaxially arranged; adjusting blocks are movably connected to the front ends of pistons of the two jacking air cylinders; the adjusting blocks are detachably connected; one sides of the two jacking air cylinders are connected with reversing valves for controlling the jacking air cylinders through pipelines; according to the application, the two symmetrically arranged jacking cylinders are arranged; the two jacking cylinders are used for jacking and fixing the workpieces on the two sides respectively; by means of the structure, the fork arm carrierof the forklift can be rapidly jacked and fixed, meanwhile, due to the fact that the two jacking air cylinders are coaxially arranged and are perpendicular to the workpieces, in the jacking process,the pushing force of the j
