[0002] With social development and the improvement of people's living standards and tastes, coffee has become a fashionable beverage and is widely favored by consumers. The coffee processing process must include a grinding process, that is, grinding coffee beans into coffee powder. Under normal conditions, coffee powder is easily oxidized and loses its aroma, so it should be used immediately after preparation, grinding only the amount needed to ensure freshness and deliciousness. Therefore, a coffee grinder that allows ordinary consumers to grind coffee beans into powder themselves has emerged.

[0003] For example, the utility model patent with authorization announcement number CN205041262U discloses a manual coffee bean grinder. This device is more energy-efficient and environmentally friendly, more hygienic and safe, has a longer service life, lower cost, and is easier to disassemble and clean after use. It is also simple and convenient to assemble and use again.

[0004] However, the handle of the device is not easy to disassemble, and it takes up more space when carried or stored, which reduces the practicality of the device. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-6 A manual coffee grinder includes: a grinding jar 1, with a grinding cup 11 threadedly screwed onto the lower end of the grinding jar 1 and a lid 12 threadedly screwed onto the upper end of the grinding jar 1; a rotating mechanism 2, rotatably mounted on the lid 12, for driving a grinding rotor 34 to rotate; and a grinding mechanism 3, installed inside the grinding jar 1, for cooperating with the grinding rotor 34 to grind coffee. The rotating mechanism 2 includes a rotating seat 21 rotatably mounted on the lid 12, a rotating end cap 22 mounted on the upper end of the rotating seat 21, a slot for inserting a rotating arm 23 between the rotating seat 21 and the rotating end cap 22, and a rotating arm 23 detachably mounted on the rotating seat 21 via a fixing component.

[0025] The working principle of this utility model is as follows: During grinding, coffee beans are added into the grinding jar 1. Then, the rotating arm 23 is rotated, which drives the rotating mechanism 2 to rotate, thereby realizing the rotation of the grinding rotor 34. Through the grinding rotor 34 and the grinding mechanism 3, the coffee beans can be ground and processed.

[0026] As a further embodiment, the fixing assembly includes a fixing groove 24 on the rotating base 21, a fixing ring 26 installed at the end of the fixing groove 24, and a fixing pin 25 slidably installed within the fixing groove 24. The end of the fixing pin 25 passes through the fixing ring 26 and extends into a fixing hole on the rotating arm 23. A fixing spring 27 is also installed within the fixing groove 24, and the upper end of the fixing spring 27 is fixedly connected to the lower end of the fixing pin 25. In this embodiment, a pressing hole is provided on the upper end of the fixing end cover 22 at the position corresponding to the fixing hole, facilitating the movement of the fixing pin 25.

[0027] When fixing, press the fixing pin 25 down to retract it into the fixing groove 24. At this time, the fixing spring 27 is compressed. Then, insert the rotating arm 23 into the slot. After the rotating arm 23 is fully inserted, the fixing spring 27 returns to its original position, which will push the fixing pin 25 up, so that the fixing pin 25 is inserted into the fixing hole on the rotating arm 23, thus completing the fixing work. The operation is simple and convenient for installation.
