[0006] A special tool for disassembling and assembling a water meter clamp includes a screwing head, and a rotating handle is fixedly connected to the outer side wall of the screwing head;

[0007] A disassembly and assembly mechanism is arranged at the bottom end of the rotating handle.

[0008] Preferably, the disassembly and assembly mechanism includes a connecting rod, the connecting rod is installed at the bottom end of the rotating handle, a sleeve is fixedly connected to the bottom end of the connecting rod, an outward expanding handle is fixedly connected to the outer side wall of the sleeve, and a connecting groove is opened at the bottom end of the sleeve.

[0009] Preferably, four connecting grooves are opened at the bottom end of the sleeve, and the outward expanding handle is fixedly connected to the outer side wall of the sleeve in a cylindrical shape.

[0010] Preferably, a connecting hole is opened at the top end of the connecting rod, and the connecting hole is snap-fitted with the bottom end of the rotating handle, and a limiting screw is threadedly connected to the inner side wall of the sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Through the setting of the outward expanding handle, the utility model can easily disassemble and assemble the water meter by knocking in the case of rust slag or other difficult disassembly and assembly on the threads of the water meter clamp, significantly improving the disassembly and assembly efficiency;

[0013] 2. In a narrow space, traditional disassembly and assembly tools may be difficult to use, while this product can be operated without removing the water meter, greatly improving the work convenience in a narrow space. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0019] As shown in Figure 1 to Figure 3 shown:

[0020] Embodiment 1: The present utility model provides a special tool for disassembling and assembling a water meter clamp, including a wrench head 1, and a rotating handle 11 is fixedly connected to the outer side wall of the wrench head 1;

[0021] A disassembly and assembly mechanism is arranged at the bottom end of the rotating handle 11. The disassembly and assembly mechanism includes a connecting rod 12. The connecting rod 12 is installed at the bottom end of the rotating handle 11. A sleeve 13 is fixedly connected to the bottom end of the connecting rod 12. An expanding handle 14 is fixedly connected to the outer side wall of the sleeve 13. A connecting slot 15 is opened at the bottom end of the sleeve 13.

[0022] Specifically, it is connected to the clamp through the connecting slot 15, which can limit the dial and is convenient for use in a narrow space.

[0023] Four connecting slots 15 are opened at the bottom end of the sleeve 13. The expanding handle 14 is fixedly connected to the outer side wall of the sleeve 13 in a cylindrical shape. A connecting hole 16 is opened at the top end of the connecting rod 12. The connecting hole 16 is snap-fitted with the bottom end of the rotating handle 11. A limit screw 17 is threadedly connected to the inner side wall of the sleeve 13.

[0024] Specifically, by knocking on the outwardly expanding handle 14 provided on the side wall, the water meter can be prevented from rusting and getting stuck.

[0025] As can be seen from the above, when the threads of the water meter clamp rust or get stuck, the water utility worker can align the four connecting notches 15 of this tool with the four "ears" of the water meter clamp to make them fit tightly. Then, use a tool such as a hammer to knock on the welded outwardly expanding handle 14. Through short and forceful tapping strokes, the rusted or stuck clamp can be loosened. By rotating the limit screw 17 to make the limit screw 17 move inward, the limit screw 17 can be connected to the concave dial.

[0026] Installation process: When installing the water meter clamp, also use the four connecting notches 15 of this tool to align with the "ears" of the clamp, and then by knocking on the outwardly expanding handle 14, the clamp can be tightly fastened at the final stage of installation.
