[0084] In the embodiment, when the product needs to be ground, the user only needs to hold the grinder with one hand and only needs to use the thumb to adjust the adjustment member 150 , that is, adjust the rotation speed of the motor 11 by rotating the adjustment member 150 .

[0085] In the embodiment, the switch 152 is a knob, and cooperates with the motor 11 that can be infinitely variable in speed. The speed of the motor 11 can be adjusted by rotating the adjustment knob. For example, when the knob is turned clockwise, the speed of the motor 11 increases, ensuring that the grinding effect can be ensured when high power output is required for grinding spices; when the knob is turned counterclockwise, the speed of the motor 11 decreases. That is, the user can grind the food or spices according to the actual need to grind the food or spices by adjusting the speed of the motor 11 to a suitable speed, ensuring that the product obtained by grinding is better.

[0086] Since different foods or spices usually have different requirements for grinding each time, they need to be ground at different rotation speeds, and the grinders on the market have a fixed motor 11 speed and cannot adapt to various products. In this embodiment, by using a motor 11 with a stepless speed change and a motor 11 with a larger speed variation range, the grinder can adapt to the grinding of more foods or spices.
