The placement cylinder 2 is disposed at the top of the mounting base 1. An elastic connector 3 is disposed on one side of the top of the mounting base 1 and the bottom of the placement cylinder 2. A cylinder 11 is disposed on the side of the mounting base 1 opposite to the elastic connector 3. The output end of the cylinder 11 is located at the edge of the bottom of the placement cylinder 2. A gravity component 4 is disposed on the side of the placement cylinder 2 away from the elastic connector 3.

[0018] The elastic connector 3 includes an upper fixing member 301, a lower fixing member 302, and a second spring 303. The upper fixing member 301 is disposed at the bottom end of the placement cylinder 2, the lower fixing member 302 is disposed at the top end of the mounting base 1, and the second spring 303 is disposed between the upper fixing base 301 and the lower fixing base 302.

[0019] The gravity component 4 includes a connecting seat 401, a connecting rod 402, and a gravity ball 403. The connecting seat 401 is disposed on the placement cylinder 2, and the connecting rod 402 is disposed at the bottom end of the connecting seat 401. The gravity ball 403 is disposed at the bottom end of the connecting rod 402.

[0020] The placement cylinder 2 is equipped with a clamping assembly.

[0021] The clamping assembly includes two symmetrically arranged arc-shaped clamping plates 5, a spring 6, and two pull rods 7. The two arc-shaped clamping plates 5 are symmetrically arranged inside the placement cylinder 2. The placement cylinder 2 has through holes on both sides for use with the pull rods 7. The pull rods 7 extend into the interior of the placement cylinder 2 through the through holes and are fixedly connected to the arc-shaped clamping plates 5. The spring 6 is sleeved on the pull rods 7. The spring 6 is located between the arc-shaped clamping plates 5 and the inner wall of the placement cylinder 2. The pull rods 7 have a U-shaped structure.

[0022] A connecting seat 8 is provided at the center of the bottom end of the placement cylinder 2, and a support seat 9 is provided at the center of the top end of the mounting seat 1.

[0024] Working principle: First, the food sample to be tested is placed inside the placement tube. The sample is fixed inside the placement tube by the operation of the clamping component and the arc-shaped clamping plate, ensuring that the sample will not move during shaking. After the sample is fixed, the cover is screwed to the top of the placement tube. The shaking frequency and amplitude of the cylinder are set as needed, and the cylinder is started so that its output end contacts the edge of the bottom of the placement tube, thereby shaking the sample.

[0025] In summary, this invention combines a cylinder and a gravity component to produce an appropriate shaking effect during the testing process, thereby improving the uniformity and accuracy of the test and ensuring reliable test results. The design of the clamping component allows for easy fixation of samples of different shapes and sizes, enhancing the adaptability and ease of use of the device.
