发明名称 Hydraulically operated hand tool for forcing open doors
摘要 A hand tool, for use with a hydraulic pump, for forcing or prying open doors and other objects. First and second jaw members, each having spaced apart fingers, are connected together by a hydraulic piston-cylinder assembly which is adapted for hydraulic connection to the hydraulic pump. The spaced apart fingers of the jaw members mesh with each other when the jaw members are positioned together. A plate member defining opposed sides is connected to the first jaw member and the second jaw member defines first and second guide members with each of the guide members projecting adjacent respective sides of the plate member and in slidable relationship with the plate member. A third guide member extends from the plate member and encircles a portion of the piston-cylinder assembly in slidable relationship with the assembly.
