[0010] Furthermore, the upper cam and the lower cam are respectively installed at the upper and lower ends of the forward-inclined impeller.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the adjustment of the distance between the upper and lower cams helps to fix the forward-tilting impeller as a whole.

[0012] Furthermore, the lower cam includes an auxiliary plate, which is mounted on the back of the lower cam.

[0013] The advantage of adopting the above-mentioned further solution is that it facilitates the auxiliary plate to help fix the lower cam.

[0014] Furthermore, the auxiliary support frame includes a slide rail and support feet. The slide rail is fixedly installed on the surface of the auxiliary support frame. The auxiliary support frame is provided in two sets, and the support feet are fixedly connected to the bottom end of the auxiliary support frame.
