[0034] Reference Figures 1 to 6 The present embodiment provides a hand-cranked coffee bean grinder with an easy-to-store handle, including a fixed part, a rotating part and a rocker 1. The rotating part rotates with the fixed part. The rocker 1 includes a hand-cranked lever part 103 and a plug-in rod part 101 plugged with the rotating part. The rotating part is rotatably connected to the plug-in rod part 101, and the rotating shaft of the rotating part and the rotating shaft of the plug-in rod part are perpendicular to each other. The plug-in rod part 101 is circumferentially provided with a limiting groove 102, and the plug-in rod part 101 and the hand-cranked lever part 103 are vertically connected to each other.

[0035] In this embodiment, the plug-in rod portion 101 of the joystick 1 is rotatably connected to the rotating part, and the rotating axis of the rotating part and the plug-in rod portion 101 are perpendicular to each other, so that the joystick 1 can be rotated to a horizontal plane when in use. After use, the joystick 1 is rotated in the opposite direction until the hand joystick portion 103 is in a vertical state and vertically and tightly attached to the outer periphery of the fixing part, thereby achieving a storage effect and making it more convenient to carry out.

[0036] Furthermore, a limiting column 201 is provided in the rotating member, and the limiting column 201 is slidably inserted into the limiting groove 102 , so that the limiting column 201 and the limiting groove 102 can slide relative to each other in the circumferential direction of the plug-in rod portion 101 .

[0037] Specifically, the rotating member includes a bottle cap 2 and a rotating shaft 3, the bottle cap 2 includes a connecting column 202 and a housing 203, a limiting hole is provided on the connecting column 202 on the bottle cap 2 along the axial direction, and the limiting hole is connected to the plug hole 204, and the limiting column 201 is inserted into the limiting hole to limit the rocker 1 and prevent the rocker 1 from being separated from the rotating member during use. In practical applications, the limiting hole can also be located at other places on the inner periphery of the plug hole 204.

[0038] In the embodiment of the present application, the central angle corresponding to the limiting groove 102 is greater than or equal to 90°. A plugging hole 204 is provided radially on the connecting column 202, and the plugging hole 204 penetrates through the outer shell 203 to form a plugging interface. This enables the rocker 1 to rotate from a grinding position to a storage position. When the rocker 1 is in the grinding position, the limiting column 201 abuts against one end in the length direction of the limiting groove 102, and the rocker 1 is in the horizontal plane.

It should be noted that the internal structure of the above internal hexagonal ball is a prior art and will not be elaborated here.

[0047] In the embodiment of the present application, the handle assembly is clamped with the hand rocker part 103. A plug-in section 1031 is provided at one end of the hand rocker part 103 away from the plug-in rod part 101. A socket 701 for non-rotating plug-in connection with the plug-in section 1031 is provided on the handle assembly, and a bayonet 1032 is provided on the plug-in section 1031. Specifically, the plug-in section 1031 includes two relatively arranged planes, and the bayonet 1032 is provided in the upper plane to prevent the handle assembly from rotating around the axis of the hand rocker part 103.

[0048] In the embodiment of the present application, the internal space of the powder bin 9 is larger than the volume of the handle assembly, so that when storing, the handle assembly can be put into the powder bin 9, making better use of the space and making the volume after storage smaller.

[0049] Working principle: When grinding, rotate the rocker 1 clockwise along the circumferential direction of the plug-in hole 204 until the rocker 1 reaches the limit position. At this time, the rocker 1 is in the horizontal plane position. Then, connect the plug-in section 1031 at the end of the handle assembly and the hand rocker part 103. The operator holds the handle part 6 and rotates it around the axis of the rotating part to start grinding. When grinding is over, force the handle assembly to move axially outward along the hand rocker part 103 to separate the handle assembly from it. Then rotate the rocker 1 counterclockwise along the circumferential direction of the plug-in hole 204 to engage the hand rocker part 103 with the fixing part 801. At the same time, put the handle assembly into the powder bin 9 to complete the storage.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
