When the assembly block 31 is embedded in the stepped groove, the assembly block 31 and the limiting groove 22 are interference fit. It can be understood that the size of the assembly block 31 should be slightly larger than the size of the limiting groove 22, so that the assembly block 31 and the limiting groove 22 are interference fit. When the assembly block 31 is embedded in or out of the limiting groove 22, a certain force needs to be applied to rotate the grinding disc bin 2. Among them, the adjacent steps of the assembly block 31 and the limiting groove 22 are arc-shaped transitions, and the arc-shaped transition can ensure that the assembly When the assembly block 31 is inserted into or engaged with the limiting groove 22, there are no sharp edges or corners between the contact surfaces of the two, thereby achieving a smooth transition, which is more conducive to precise engagement between the two and can reduce wear on the assembly block 31 and the limiting groove 22. This engagement method can ensure that the assembly block 31 forms a close contact with the limiting groove 22 after being inserted. Even if the coffee grinder is subjected to vibration or impact during operation, the grinding disc compartment will not easily loosen or fall off during operation, thereby improving the assembly stability between the coffee grinding assembly and the coffee grinding body 1.
