[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-2 A hand-cranked aluminum alloy grinder shown includes a housing 1 and a grinding chamber 7, wherein the grinding chamber 7 is used for grinding objects;

[0026] A receiving bin 8 is installed at the lower end of the outer shell 1, and is used to collect the ground powder particles. A bottom groove 11 is opened on the inner wall surface of the receiving bin 8, and a frame 12 is provided on one side of the bottom groove 11. The outer wall of the frame 12 is connected to a connecting block 13, and a first damping reset rod 14 is fixedly installed on the other side of the connecting block 13. A filter screen 15 is connected to the inner wall of the frame 12. The filter screen 15 is movably connected to the receiving bin 8, and the center line of the frame 12 coincides with the center line of the filter screen 15. The setting of the filter screen 15 can filter the powder after grinding, and pour the powder with larger particles back into the grinding bin 7 for secondary processing, so that the ground powder is finer.

[0027] like Figure 1 and Figure 4 As shown, the inner wall of the grinding chamber 7 is movably connected with a transmission rod 2, the upper end of the transmission rod 2 is connected with a top cover 3, the upper end of the top cover 3 is movably connected with a handle 4, one end of the handle 4 is connected with a rotating rod 5, and the upper end of the handle 4 is penetrated by a rotating shaft 6. The setting of the handle 4 can drive a more flexible rotating grinding device.

[0028] like Figure 1 and Figure 2 As shown, a base 9 is fixedly installed at the lower end of the receiving bin 8, and an adsorption sticker 10 is provided at the lower end of the base 9. The adsorption sticker 10 can fix the grinder on the table so that the grinder can exert better force during the grinding process.

[0029] like Figure 1 and Figure 2 As shown, a slot 16 is provided on the inner wall surface of the receiving bin 8, and a scale 17 is movably connected to the inner wall of the slot 16. The scale 17 provided inside the receiving bin 8 can determine the amount of grinding particles required.

[0030] like Figure 3 As shown, the outer wall of the shell 1 is provided with a first sound insulation cover 18, and a docking port 19 is opened on one side surface of the first sound insulation cover 18, and a second sound insulation cover 20 is provided on one side of the first sound insulation cover 18, and a docking rod 21 is fixedly installed on one side of the second sound insulation cover 20, and second damping reset rods 22 are fixedly installed on both sides of the docking rod 21.

[0031] The working principle of the utility model is as follows: first, the outer shell 1 is placed at the designated position through the adsorption sticker 10 connected to the lower end of the base 9. The adsorption sticker 10 can adsorb the outer shell 1 on the table surface to prevent the outer shell 1 from sliding during subsequent use. Secondly, the top cover 3 is opened, and then the objects to be ground are added into the grinding bin 7, and then the top cover 3 is closed, so as to manually turn the handle 4 so that the handle 4 drives the grinding head inside the grinder to grind the objects. After the grinding is completed, the receiving bin 8 can be taken out. After taking out the receiving bin 8, the filter screen 15 inside the receiving bin 8 can be removed, so as to judge the amount of grinding particles required according to the scale 17 set inside the receiving bin 8. Finally, the inside of the device can be cleaned when the device is not in use.
