"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1, a portable bean grinder comprises a top shell 8 and a bottom shell 9 which are fixed with each other and arranged up and down, and a main body arranged in the top shell 8 and the bottom shell 9, wherein the main body comprises a frame 1, a motor 13 fixed in an opening at the top of the frame 1, an outer cutter head 15 embedded in an opening at the bottom of the frame 1, an inner cutter head 14 which is concentrically and movably arranged in the outer cutter head 15 and mutually matched with the outer cutter head 15, and a central shaft 2 which is vertically and concentrically connected between a rotating shaft of the motor 13 and the inner cutter head 14; after the starter motor 13, the axis of rotation of motor 13 can drive interior blade disc 14 with the help of axis 2 and rotate in 15 inside outer blade discs, and then will be located the coffee bean grinding between interior blade disc 14 and the outer blade disc 15, and above-mentioned principle is prior art, and the utility model discloses a characteristics lie in: the adjusting mechanism comprises a machine sleeve 3, an anti-rotation sleeve 4 and a knob 5; the top of frame 1 is formed with cartridge type heavy chamber 101, prevent that the activity of rotary sleeve 4 is located in cartridge type heavy chamber 101 and only can reciprocate and can not take place relative rotation with frame 1, the top at rotary sleeve 4 is fixed to the cover 3 and is arranged in cartridge type heavy chamber 101, knob 5 embedding spiro union is inside and fix the open-top department at cover 3 at the opening part of cartridge type heavy chamber 101, motor 13 embedding is fixed in cover 3, the vertical downward setting of axis of rotation of motor 13, the upper end of axis 2 is passed with one heart and is prevented rotary sleeve 4 and fix in the axis of rotation of motor 13.

The dial 6 is also fixed on the top of the knob 5.
