A positioning sleeve 3 is installed on the base 2, and the manual coffee grinder body 1 is placed inside the positioning sleeve 3. A retaining sleeve 4 is installed on the outer shell of the manual coffee grinder body 1. A retaining bracket 5 is movably installed on the base 2, and the end of the retaining bracket 5 is engaged in the retaining sleeve 4. A U-shaped clamp 6 is installed at the end of the base 2, and a movable fixing plate 7 is movably disposed inside the U-shaped clamp 6. A contact pad 8 is installed at the bottom of the movable fixing plate 7. After pre-positioning a set of retaining brackets 5 far apart, the manual coffee grinder body 1 is inserted into the positioning sleeve 3. The set of retaining brackets 5 moves closer together and inserts into the retaining sleeve 4 to fix the manual coffee grinder body 1. Then, the U-shaped clamp 6 is clamped onto the table surface, and the movable fixing plate 7 moves downward and abuts against the table surface to fix the device. The contact pad 8 directly contacts the table surface, which can increase the contact friction with the table surface and enhance the stability of the device fixation. When grinding, users can simply turn the handle on the main body 1 of the manual coffee grinder to grind the coffee beans.

[0023] Furthermore, to drive a pair of card holders 5 to move and insert into or remove from the card sleeve 4, a connecting rod 9 is rotatably mounted on the card holder 5, a push rod 10 is movably mounted on the base 2, the other end of the connecting rod 9 is rotatably mounted on the push rod 10, a support block 11 is mounted on the base 2, a spring 12 is mounted on the push rod 10 and the support block 11, a slide rail 14 is mounted on the base 2, a sliding sleeve 13 is mounted at the bottom of the push rod 10, the sliding sleeve 13 is slidably sleeved on the slide rail 14, and a lever 15 is mounted on the push rod 10; the lever 15 is pushed in advance towards the positioning sleeve 3, the push rod 10 moves forward, the push rod 10 moves forward, a set of connecting rods 9 rotates and opens, the rotation and opening of the set of connecting rods 9 pushes a set of card holders 5 to move away from each other and remove them from the card sleeve 4;
[0024] Release the lever 15. At this time, under the reset action of the spring 12, the push rod 10 will be pulled to move backward. The push rod 10 will move back and forth, which will drive a set of connecting rods 9 to reverse and close. The reverse and closing of the set of connecting rods 9 will push a set of card holders 5 to move closer to each other and insert into the card sleeve 4.
[0025] Furthermore, in order to guide the movement of the card holder 5, a guide frame 16 is installed on the base 2, and a guide sleeve 17 is installed on the bottom of the card holder 5. The guide sleeve 17 is slidably installed on the guide frame 16. The sliding of the guide sleeve 17 on the guide frame 16 can guide the movement of the card holder 5, so that the card holder 5 can only move along the guide frame 16.
[0026] Furthermore, in order to guide the movement of the movable fixing plate 7 and the contact pad 8, a guide rod 18 is installed on the U-shaped clamp 6, and sliding holes 19 are opened on the movable fixing plate 7 and the contact pad 8. The guide rod 18 is inserted through the sliding hole 19.

[0028] Working principle: When in use, push the lever 15 towards the positioning sleeve 3. The lever 15 will cause the push rod 10 to move forward. The push rod 10 will cause a set of connecting rods 9 to rotate and open. The rotation and opening of the set of connecting rods 9 will push a set of card holders 5 to move and move away from each other. Then insert the manual coffee grinder body 1 into the positioning sleeve 3 and release the lever 15. At this time, under the reset action of the spring 12, the push rod 10 will be pulled to move backward. The back and forth movement of the push rod 10 will cause a set of connecting rods 9 to reverse and close. The reverse and closing of the set of connecting rods 9 will push a set of card holders 5 to move closer to each other and insert into the card holder 4 to fix the manual coffee grinder body 1. Next, clamp the U-shaped clamp 6 onto the tabletop and turn the knob 21 inwards. The rotation of the knob 21 will cause the screw 20 to rotate. The screw 20's rotation and downward movement will cause the movable fixing plate 7 to move downwards and press against the tabletop, securing the device. The contact pad 8 directly contacts the tabletop, increasing friction and enhancing the stability of the device. During grinding, the user can directly turn the handle on the manual coffee grinder body 1 to grind the coffee beans. There's no need to hold the manual coffee grinder body 1 with one hand and turn the handle with the other, making operation more convenient and reducing the risk of the collection box at the bottom of the manual coffee grinder body 1 falling off.
