The container is limited inside the U-shaped structure, and the first clamping arm 310 and the second clamping arm 320 clamp the base of the container from two sides respectively. Each side can hold the container by using the elastic structure. In this way, the containers of different specifications can be clamped on the device more stably, the stability of operation is improved, the containers of different specifications can be clamped, the flexibility is high, the device is convenient to disassemble and clean, the containers can be replaced to avoid cross contamination. It should be noted that the second elastic holding part 322 and the first elastic holding part 313 can be made of rubber material or plastic material with a certain elasticity, which can be deformed adaptively according to the clamped container. The first supporting part 312 and the second supporting part 321 can be made of plastic or metal material as a skeleton, and the elastic rubber material is covered on the outside, which can also play a certain protection role to avoid wear of the powder container.

[0033] Referring to Figure 2 In an embodiment, the two sides of the first supporting part 312 are provided with guide protrusions 3121, and the two sides of the second supporting part 321 are provided with grooves 3211 matched with the guide protrusions 3121. In this way, the sliding direction of the second supporting part 321 relative to the first supporting part 312 can be guided, and the stability of the device during adjustment is improved.

[0034] In an embodiment, the first supporting part 312 is provided with a sliding groove 3122, and the second supporting part 321 is provided with a sliding bolt 3212 which is detachably connected with the locking part 330 by penetrating the sliding groove 3122.

[0035] In an embodiment, the locking part 330 is a locking nut.

[0036] In use, the locking nut is loosened, the relative positions of the first supporting portion 312 and the second supporting portion 321 are adjusted, until the first clamping arm 310 and the second clamping arm 320 clamp the container, then the locking nut is tightened, the clamping is completed, the driving motor 100 is started, the driving shaft 110 drives the clamping assembly 300 to rotate, the container is clamped on the clamping assembly 300 and rotates with it, and the internal powder is mixed.

[0037] In an embodiment, the small powder mixer further comprises a base 400 and a housing 500 fixed to the base 400, and the driving motor 100 is arranged inside the housing 500, and the driving shaft 110 extends out of the housing 500.

[0042] In an embodiment, widened elastic portions 3221 are arranged at the middle positions of the two sides of the U-shaped structure. The widened elastic portions 3221 at the middle positions of the two sides of the U-shaped structure can hold the powder container from the front and the back, increase the contact area between the U-shaped structure and the powder container, and improve the stability of clamping.

[0043] In an embodiment, an elastic baffle 3111 is arranged at the other end of the first side clamping portion 311, and the elastic baffle 3111 forms an obtuse angle with the first side clamping portion 311. In this embodiment, the elastic baffle 3111 is arranged on the first side clamping portion 311 and limits the end surface of the powder container, further improving the stability of clamping.
