During the water absorption process, the cutting knife 108 works to cut and crush the dirt in the sewage, and then discharges it through the water outlet 103.

[0026] Specifically, the mounting assembly 2 includes a mounting block 201 fixedly mounted above the outer side of the housing 102, a threaded hole 202 is provided on the top of the mounting block 201, a threaded rod 203 is provided inside the threaded hole 202, a rotating block 206 is installed at the bottom of the threaded rod 203, a connecting plate 204 is provided on the top of the threaded rod 203, a fixing rod 205 is fixedly connected to one side of the bottom of the connecting plate 204, a connecting spring 207 is provided on the outside of the threaded rod 203 and at the bottom of the mounting block 201, the threaded rod 203 is connected and installed with the threaded hole 202 through a thread, and the top of the threaded rod 203 is rotatably connected to the bottom of the connecting plate 204 through a bearing, and four mounting assemblies 2 are provided, and the four mounting assemblies 2 are equidistantly distributed above the outer side of the housing 102 along the circumferential direction, and the fixing rod 205 cooperates with the fixing hole 110. When the pump body 1 fails and the electric pump needs to be repaired, The user can rotate the four rotating blocks 206 in sequence to drive the threaded rod 203 to rotate inside the threaded hole 202, drive the connecting plate 204 and the fixing rod 205 to move upward until the fixing rod 205 is disengaged from the fixing hole 110, and then rotate the connecting plate 204 to rotate the fixing rod 205 to the side away from the pump cover 101. After that, the pump cover 101 can be removed from the housing 102 for subsequent maintenance work. After the maintenance is completed, the pump cover 101 is covered on the top of the housing 102, and then the connecting plate 204 is rotated, the fixing rod 205 is rotated to the top of the fixing hole 110 and the rotating block 206 is rotated until the fixing rod 205 is plugged into the fixing hole 110 to complete the installation and fixing work.

The fixed rod 205 is disengaged from the fixing hole 110, and then the connecting plate 204 is rotated to rotate the fixing rod 205 to the side away from the pump cover 101. After that, the pump cover 101 can be removed from the shell 102 for subsequent maintenance work. After the maintenance is completed, the pump cover 101 is covered on top of the shell 102, and then the connecting plate 204 is rotated to rotate the fixing rod 205 to above the fixing hole 110 and then rotate the rotating block 206 until the fixing rod 205 is inserted into the fixing hole 110 to complete the installation and fixing work.
