The invention belongs to the technical field of engineering machinery, and discloses a hydraulic flat-pushing full-automatic double-safety quick connector. The quick connector comprises a shell, a front safety hook, a safety pin, a hydraulic cylinder, a limiting pin, a rear fuse hook safety hook, a torsion spring, an upper shaft and a safety valve; the hydraulic cylinder is horizontally installedat the inner lower part of the shell, and the front safety hook is connected with the front side of the shell through an articulated shaft; the front end of the hydraulic cylinder is connected with the front safety hook, and the rear end of the hydraulic cylinder is connected with the shell through an oil cylinder shaft; the rear safety hook and the torsion spring are of an integrated structure, and the limiting pin is installed at the position, on the front side of the rear safety hook, of the shell; the rear safety hook is driven by the hydraulic cylinder; the hydraulic cylinder and the safety valve are of the integrated structure; the hydraulic cylinder and a compression spring are of the integrated structure. According to the quick connector, a hydraulic flat-pushing double-safety connector is adopted, and is easy to use, and the structure is safer.
