[0003] During the processing of plunger pumps, disassembly and assembly tools are often used. A Chinese utility model patent with announcement number CN210704590U discloses a disassembly and assembly tool for a plunger pump. The disassembly and assembly tool comprises: a plunger foot, a crossbeam, a top plate, and a hanging ring. One end of the crossbeam is connected to the top plate, the other end of the crossbeam is downwardly connected to the top of the plunger foot, and a designated position of the crossbeam is downwardly connected to the hanging ring. When the disassembly tool is used to disassemble and assemble the plunger pump, the hanging ring is used to cover the plunger pump and hang the disassembly and assembly tool on the plunger pump. The plunger foot is used to be placed in a groove of the plunger of the plunger pump. The top plate is used to cooperate with the plunger foot to clamp the plunger of the plunger pump, so that the plunger of the plunger pump is fixed during disassembly and assembly, thereby separating and combining the connecting rod and plunger when the connecting rod continues to move. This utility model improves work efficiency and also prevents damage to the plunger pump during disassembly and assembly.
