One end of the front fixing plate 71 and the rear fixing plate 72 are provided with a rotating shaft 74 to connect with each other, so that the front fixing plate 71 and the rear fixing plate 72 form an opening and closing structure, and its structural principle is similar to that of a conventional door hinge. The front fixing plate 71 and the rear fixing plate 72 retain a fitting spacing 8 when they are in a closed state, that is, when the front fixing plate 71 and the rear fixing plate 72 are folded, a fitting spacing 8 is formed, and the fitting spacing 8 is used to fit and fix the docking flange 1 3 and the docking flange 2 5. In order to better position and match the docking flange 13 and the docking flange 25 when docking, a front locator 711 for fixing the docking flange 3 is provided on the inner side of the front fixing plate 71, and the front locator 711 corresponds to the mounting hole 131 set on the docking flange 3, and a rear locator 721 for fixing the docking flange 25 is provided on the inner side of the rear fixing plate 72, and the rear locator 721 corresponds to the mounting hole 251 set on the docking flange 25; the docking flange 13 of the water outlet pipe 2 on the water pump 1 and the docking flange 25 of the connecting pipe 4 are fixed and positioned by the front fixing plate 71 and the rear fixing plate 72 of the clamping fixture 7, and the water outlet pipe 2 and the connecting pipe 4 are connected to each other by the dead weight of the water pump 1.

[0019] In the embodiment, the thickness of the front fixing plate 71 and the rear fixing plate 72 is 5-10 mm. The fitting spacing 8 is equal to the fitting thickness of the docking flange 1 3 and the docking flange 2 5, and the fitting thickness includes the application thickness of the sealing gasket 6. Specifically, the fitting spacing 8 is equal to or slightly smaller than the sum of the fitting thicknesses of the docking flange 1 3, the docking flange 2 5 and the sealing gasket 6.

[0020] The front fixing piece 71 and / or the rear fixing piece 72 are of a right-angle structure, so that the front fixing piece 71 and the rear fixing piece 72 form a fixed slot when they are in a closed state after being connected and fixed to each other by the rotating shaft 74 .
