[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application;

[0016] Referring to Figs. 1-3 A non-standard spring dismounting tool for a plunger pump piston, comprising a lead screw 1, one end of the lead screw 1 is fixed with a joint 2, an internal hex socket 3 is formed at the end of the joint 2, the internal hex socket 3 is used in cooperation with a hex wrench, one end of the hex wrench can be inserted into the internal hex socket 3, so that the lead screw 1 as a whole can be rotated subsequently.

[0017] The other end of the lead screw 1 is installed with a moving nut 4 and a rotating sleeve 5, and the moving nut 4 is located between the joint 2 and the rotating sleeve 5, the moving nut 4 is screw-mounted with the lead screw 1, the rotating sleeve 5 is rotationally installed with the end of the lead screw 1 away from the joint 2, and the side surfaces of the moving nut 4 and the rotating sleeve 5 are both fixed with pawls 7.

[0018] Further, two limiting stop rings 6 are fixed at the end of the lead screw 1 away from the joint 2, and the rotating sleeve 5 is rotationally installed on the lead screw 1 between the two limiting stop rings 6. In the present embodiment, the rotating sleeve 5 is a nut rotationally installed at the end of the lead screw 1, when the lead screw 1 rotates, the rotating sleeve 5 will not rotate with the lead screw 1, and when in use, the pawls 7 on the rotating sleeve 5 are abutted against one side of the notch of the non-standard spring 8, and the moving nut 4 can move along the lead screw 1 when the lead screw 1 rotates, and can be close to or away from the rotating sleeve 5.

[0019] Further, a tab is installed on the side surface of the moving nut 4 and the rotating sleeve 5, and the tab and the pawl 7 on the same side form a ninety-degree angle. The tab can be conveniently placed in the notch of the non-standard spring 8, so that the two pawls 7 are respectively abutted against both sides of the notch of the non-standard spring 8. And the rotating of the moving nut 4 when dismounting the non-standard spring 8 can also be avoided.

[0020] In use, as shown in Fig. 3 the rotating screw 1 or rotating the moving nut 4, adjusting the position of the moving nut 4 on the screw 1, so that the moving nut 4 close to the rotating sleeve 5, and the two pawls 7 are respectively on both sides of the gap of the non-standard spring 8. Try to put the screw 1 horizontally above the rubber seal, insert the hex wrench into the inner hex socket 3, continue to rotate the screw 1 with the hex wrench, and press the two tabs at the same time so that the moving nut 4 and the rotating sleeve 5 do not rotate, so that the moving nut 4 can be controlled to move along the screw 1 with the rotation of the screw 1, and at this time the moving nut 4 gradually moves away from the side of the rotating sleeve 5, so as to increase the distance between the two pawls 7, and the pawls 7 are used to open the non-standard spring 8, so as to disassemble the non-standard spring 8 from the installation groove above the piston. The whole disassembly process is simple and convenient, and will not cause scratches on the surface of the piston and the rubber seal, and is more suitable for actual use.
