[0014] (1) By installing the vertical plate at the top position of the bearing plate, and then assembling the driving motor on the side of the vertical plate. After the driving motor works, it drives the transmission shaft to rotate. Thus, when the transmission shaft rotates, it drives the transmission disk to perform eccentric rotation. Assemble the placement plate at a position near the lower side of the transmission disk. A clamping groove is formed inside the side of the placement plate. Therefore, this clamping groove is used to place the test tube during the extraction and purification of food samples. Then start the first telescopic rod to work and drive the arc-shaped clamping plate to move horizontally. Thus, the arc-shaped clamping plate can perform clamping treatment on the test tube. The protective pad is adhesively fixed to the side of the arc-shaped clamping plate. Thus, the arc-shaped clamping plate forms contact protection. During oscillation, since the protection base is assembled at the side position on the top of the bearing plate, if the test tube drops, it will be protected by the sponge pad from dropping. And this placement groove is formed inside the protection base. Therefore, the sponge pad is placed in the placement groove, and the pressing strip presses the upper side position of the sponge pad. Thus, during the working process, the overall oscillation clamping ability and protection ability are preferably improved;

[0015] (2) The anti-collision pad is adhesively fixed by using the first adhesive layer, and the top position inside the anti-collision pad is adhesively fixed to the shaping plate by using the second adhesive layer. Thus, the shaping plate plays an upper shaping function, and the anti-collision pad is filled with buffer cotton. Therefore, lower anti-collision protection is formed when the bearing plate moves up and down. In this way, the overall protection ability is improved well during the working process;

[0016] (3) By assembling the adjustment box on both sides above the bottom plate, the servo motor can drive the threaded rod to rotate after working. Therefore, a certain vertical adjustment is formed after the cooperation of the threaded rod and the threaded block. The connection and installation with the bearing plate are completed by the cooperation of the mounting plate and the mounting bolt. Therefore, the bearing plate can move up and down correspondingly, and the guiding work can be formed by the cooperation of the guiding block and the guiding rod during this process. In this way, the overall height adjustment ability is improved well during the working process. BRIEF DESCRIPTION OF THE DRAWINGS
