[0026] In this embodiment, if Figure 3As shown, the inner wall of the pump body 1 is provided with a slot 101 and a slot 2 102, and they are arranged up and down, the outer surface of the upper seat 9 is provided with a block 1001, the outer surface of the lower seat 10 is provided with a block 2 1001, the block 1 901 is movably connected with the slot 101, the slot 2 102 is movably connected with the block 2 1001, the slot 101 and the slot 2 102 opened on the inner wall of the pump body 1 are used to fix the crushing mechanism 8 with the block 1 901 on the outer surface of the upper seat 9 and the block 2 1001 on the outer surface of the lower seat 10, respectively.

[0027] In this embodiment, if Figure 4 As shown, the transmission tube 11 is arranged between the upper seat 9 and the lower seat 10, and the upper seat 9 and the lower seat 10 are both round frame-type. A support frame 902 is fixedly connected inside the upper seat 9, and a turntable 903 is movably connected to the lower end of the support frame 902.
