When the rotating shaft 1 rotates, it will drive the impeller 8 to rotate together, thereby adsorbing objects, and the inner cavity of the pump body 7 is provided with a suction pipe assembly 9, and one side of the pump body 7 is provided with a discharge pipe assembly 10. The function of the suction pipe assembly 9 is to filter large particles to prevent large particles from being adsorbed and causing blockage to the whole.

[0020] For example 2, please refer to Figures 2 to 4, this embodiment includes all the structures of the embodiment 1, specifically: the support tube assembly 5 includes a support base 51, a support tube 1 52 is arranged on the top of the support base 51, the support tube 1 52 is connected to each other through a support plate connected by sliding up and down on the top of the support base 51, and the support plate is fixedly connected to the shock-absorbing spring 59 in the inner cavity of the support base 51, the top of the support tube 1 52 is clamped with a support tube 2 53, and the inner cavity of the support base 51 is fixedly connected with a plurality of shock-absorbing springs 59, the function of the shock-absorbing spring 59 is to reduce the vibration generated during the working process, the bottom of both sides of the support tube 2 53 are fixedly connected with clamping blocks 54, and the two clamping blocks 54 are arranged in a trapezoidal shape, and at the same time, both sides of the two clamping blocks 54 are provided with clamping grooves, the clamping grooves and the limiting bolts 56 are matched with each other, and the clamping grooves and the limiting bolts 56 are clamped with each other later, so as to complete the connection between the support tube 1 52 and the support tube 2 53, both sides of the support tube 1 52 are fixedly connected with a placement box 55, and the internal sliding connection of the placement box 55 is connected with the limiting bolt 56, and The limit bolt 56 passes through the inner wall of the support tube 1 52, and the surface of the limit bolt 56 is sleeved with a spring 1 57, which is used to reset and limit the limit bolt 56.

When the clamping blocks 54 are lowered, the limit bolts 56 are squeezed to both sides, thereby driving the compression of the spring 1 57. When the limit bolts 56 match the clamping grooves on both sides of the clamping blocks 54, they do not need to be lowered further. At this time, it means that the installation and clamping of the support tube 1 52 and the support tube 2 53 are completed.

[0022] When the support tube assembly 5 is subsequently disassembled, the limiting bolts 56 are pulled toward both sides to remove it from the clamping groove of the clamping block 54 , and then the support tube 2 53 is taken out to complete the disassembly work.
