[0008] Preferably, as described in any of the above embodiments, a switch is provided on the top surface of the housing, and the diameter of the inner wall of the top cover is adapted to the diameter of the top of the outer wall of the crushing tank.

[0009] The technical effect achieved by adopting the above solution is that the switch makes it easy to press the top cover of the crusher housing to be closed, so that the top cover is sealed tightly at the top of the crushing tank while the switch is pressed to start the machine.

[0010] Preferably, in any of the above schemes, the distribution diameter of the plurality of crushing blades is adapted to the diameter of the inner wall of the crushing tank, and the up-and-down sliding stroke of the cam driving the connecting plate is adapted to the depth of the inner wall of the crushing tank.
