One side of the sliding cavity 15 is open. A sliding plate 17 is slidably installed inside the sliding cavity 15. One end of the sliding plate 17 can pass through the opening of the sliding cavity 15 and extend to the outside of the bottom shell 13. A bottom plate 20 is covered at the lower end of the bottom shell 13. A protrusion 19 is integrally formed at the lower end of the sliding plate 17. The lower end of the protrusion 19 is flush with the lower end of the bottom plate 20.

[0030] Furthermore, refer to Figure 5 The outer wall of the discharge nozzle 5 is integrally formed with a limiting plate 6, which can be inserted into the outer wall of the grinding chamber 2; the limiting plate 6 has a C-shaped structure and the opening of the C-shaped limiting plate 6 faces downward.

[0031] Furthermore, refer to Figure 2 The grinding chamber 2 is equipped with a rotating grinding blade 3, and the surface of the grinding blade 3 is electroplated with a gold plating layer.

[0032] Furthermore, refer to Figure 3 The opening of the sliding cavity 15 is integrally formed with a first limiting block 16, and the sliding plate 17 is integrally formed with a second limiting block 18. The first limiting block 16 and the second limiting block 18 are in movable contact and are used to prevent the sliding plate 17 from disengaging from the sliding cavity 15.

[0033] Furthermore, refer to Figure 3 The bottom shell 13 is integrally formed with multiple sets of connecting ears 14, which are fixedly connected to the motor compartment 1 by screws.

[0034] Furthermore, refer to Figure 3 The bottom shell 13 has a through groove 21 inside, which is connected to the motor compartment 1. The through groove 21 is used to improve heat dissipation.

[0035] Furthermore, refer to Figure 6 The inner wall of the motor compartment 1 is integrally formed with multiple battery compartments 22, and rechargeable batteries are placed inside the battery compartments 22.

[0036] Working principle:

[0037] Before use, use your fingernail to pull the protrusion 19 outward, so that the assembly of the protrusion 19 and the sliding plate 17 extends outward through the opening of the sliding cavity 15. Continue to pull the assembly of the protrusion 19 and the sliding plate 17 until the first limiting block 16 in the sliding cavity 15 abuts against the second limiting block 18 on the sliding plate 17.
