[0050] When the movement 2 is close to the cutter head, the movement 2 can be placed in the housing 1, and the movement 2 is in a storage state;
[0051] When the movement 2 is away from the cutter disc, part of the movement 2 is moved out of the housing 1, so that the housing 1, the movement 2 and the cutter disc form a receiving space, and at this time the movement 2 is in an extended state;
[0052] The outer periphery of the movement 2 is provided with a slide groove, and the housing 1 is provided with a limit pin 6, and the limit pin 6 can slide along the slide groove;
[0053] The slide groove includes a limiting section. When the limiting pin 6 is located in the limiting section, the movement 2 is in an extended state, and the movement 2 will not slide along the axial direction of the rotating shaft 3 due to its own weight.
[0054] The present embodiment provides a coffee bean grinder, in which the movement 2 and the housing 1 are arranged to be relatively slidable, so that when the movement 2 is axially close to the cutter disc along the rotating shaft 3, the movement 2 can be placed in the housing 1 for storage, thereby effectively saving the space occupied by the movement 2 and being convenient to carry; and when the movement 2 is axially away from the cutter disc along the rotating shaft 3, the movement 2 is extended from the housing 1, and the accommodation space surrounded by the housing 1, the movement 2 and the cutter disc provides space for grinding beans, and the cutter disc is driven to rotate by the movement 2 to grind beans, thereby realizing the grinding function under the premise of reducing the volume of the coffee bean grinder;
[0055] By providing the limit pin 6 and the limit segment, it is ensured that the movement 2 will not slide due to its own weight when extended and interfere with the normal grinding process, and the relative position of the movement 2 and the housing 1 can be kept stable without manual support.

[0057] The second vertical sliding section 402 is connected to an end away from the first vertical sliding section 401;
[0058] In actual use, the operator can lift the movement 2 upwards, and the limit pin 6 slides in the first vertical sliding section 401. When the movement 2 cannot be lifted further, the movement 2 is rotated to make the limit pin 6 enter the horizontal sliding section 404. At this time, the movement 2 is in an extended state, and the limit pin 6 in the horizontal sliding section 404 prevents the movement 2 from sliding along the axial direction of the rotating shaft 3.
[0059] When the movement 2 needs to be completely separated from the shell 1, the movement 2 is continued to be rotated and an upward pulling force is applied to the movement 2 until the limit pin 6 enters the second vertical sliding section 402. At this time, the movement 2 can be completely separated from the shell 1, which is convenient for loading coffee beans.
[0060] In a specific embodiment, Figure 2 and Figure 3 As shown, it also includes a material receiving cup 7, the outer periphery of one end of the housing 1 away from the movement 2 is provided with a first step portion 101 and a second step portion 102, and a stopper 701 is provided on the inner wall of the material receiving cup 7;
[0061] When the second step portion 102 is arranged opposite to the stopper 701, the second step portion 102 abuts against the top of the stopper 701, and the housing 1, the blade disc and the receiving cup 7 form a coffee powder receiving chamber to collect coffee powder obtained after the coffee beans are ground by the blade disc;
[0062] When the first step 101 is arranged opposite to the stopper 701, the end of the housing 1 away from the end of the movement 2 abuts against the bottom inner wall of the receiving cup 7, thereby reducing the space occupied by the grinder and making it easy to carry;
[0063] In actual use, two first step portions 101 and two second step portions 102 are provided on the outer periphery of the movement 2. The first step portions 101 and the second step portions 102 are arranged at intervals, so that the shell 1 can be pulled out of the material receiving cup 7. When the shell 1 is put into the material receiving cup 7 again, the first step portion 101 is aligned with the stop block 701, so that the shell 1, the blade disc and the material receiving cup 7 form a coffee powder receiving chamber.
[0064] In a specific embodiment, Figure 5 As shown, the movement 2 includes a movement housing 201 and a motor 202, a driving gear 203, a battery 204 and a driven gear 205 arranged in the movement housing 201, and a through hole is opened on the movement housing 201;

The shaft hole of the driven gear 205 is arranged opposite to the through hole, so that the rotating shaft 3 can be inserted into the through hole and engaged with the shaft hole of the driven gear 205.
[0066] The movement 2 slides along the rotating shaft 3 through the through hole provided on the movement housing 201, and the movement 2 is pulled out from the housing 1 and separated from the rotating shaft 3, so as to facilitate the loading of coffee beans. After the coffee beans are loaded, the rotating shaft 3 is reinserted into the movement 2 through the through hole and engaged with the shaft hole of the driven gear 205 to transmit torque. The movement 2 drives the cutter head to rotate through the rotating shaft 3 to grind the beans. After the grinding is completed, the movement 2 is reinserted into the housing 1.
[0067] The driving gear 203 drives the driven gear 205 to rotate, so that the driven gear 205 drives the rotating shaft 3 to rotate, and then the rotating shaft 3 drives the blade to rotate, so as to grind beans.
[0068] In a specific embodiment, the rotating shaft 3 is a square shaft, and the driven gear 205 is provided with a square shaft hole adapted to the cross section of the square shaft;
[0069] If the rotating shaft 2 is a round shaft, a key needs to be installed to engage with the shaft hole of the driven gear 205 to transmit torque. The movement 2 needs to be repeatedly pulled out and inserted into the movement 2. The rotating shaft 2 with a key is inconvenient to disassemble and assemble. The square shaft is convenient for disassembly and assembly and can effectively transmit torque.
[0070] In a specific embodiment, Figure 4 and Figure 5 As shown, the movement housing 201 is provided with an outer edge 206 at one end away from the housing 1. In the storage state, the outer edge 206 abuts against the end of the housing 1 close to one end of the movement housing 201. By providing the outer edge 206, the movement 2 will not completely enter the housing 1, making it convenient for the operator to take the movement 2.
