[0042] As shown in Figure 4As shown, the test tube support and mixing mechanism 4 includes a limiting frame 41 fixedly installed on the top of the base 11. Multiple racks A42 are evenly fixedly installed on the inner side of the limiting frame 41 from left to right. A movable frame 43 is slidably nested inside the limiting frame 41. Multiple rotating seats 44 are rotatably nested on the top of the movable frame 43 via bearings. A toggle bar is fixedly installed on the top of the rotating seat 44 and a gear B45 that meshes with the adjacent rack A42 is fixedly installed on the bottom. A support frame 46 is rotatably installed on the top of the inner side of the movable frame 43 via a pin. A torsion spring is fixedly connected between the movable frame 43 and the support frame 46.

During the backward and forward movement of the limiting frame 41, multiple gears B45 will rotate under the drive of the adjacent rack A42. When the gears B45 rotate, they drive the rotating seat 44 to rotate synchronously.

9. An analysis method of a stabilizer characterized by, The analysis device using the stabilizer of claim 8 is realized, and the method specifically comprises the following steps: S1, the two electric sliding blocks drive the moving plate to move back synchronously, the moving plate moves back to drive the gear A to rotate through the rack B, the gear A drives the output roller to rotate inside the plurality of containing shells A through the rotating shaft, the output roller rotates to drive the plurality of quantitative grooves containing the quantitative stabilizer to rotate, until the opening of the quantitative groove is collinear with the adjacent output pipe A, at this time, the different types of stabilizers in the plurality of quantitative grooves fall into the plurality of test tubes inside the plurality of eccentric holes through the plurality of output pipes A and are collected; S2, the connecting spring drives the traction plate to move back synchronously when the moving plate moves back, the traction plate moves back to drive the traction rod to move back synchronously inside the connecting frame, the quantitative groove is communicated with the adjacent output pipe A, the rack B is disengaged with the adjacent gear A, and the traction rod moves to the last end inside the connecting frame; S3, with the continuous backward movement of the moving plate, the moving frame continuously moves in the limiting frame through the connecting frame and the back plate, until the moving frame moves from the front end to the last end inside the moving frame, at this time, the back of the moving frame is attached to the inner wall of the limiting frame, the back of the moving plate is attached to the protruding part at the rear end of the piston rod, and the plurality of test tubes move to the positions directly below the plurality of output pipes B; S4, due to the blocking of the limiting frame, the moving frame cannot continue to move back, with the continuous backward movement of the moving plate, the connecting spring is continuously stretched, and the moving plate drives the piston rod to move back synchronously, the piston rod moves back to drive the piston plate to enter the quantitative piston cylinder from the opening of the quantitative piston cylinder, at this time, with the continuous backward movement of the piston plate, the blank solvent inside the quantitative piston cylinder enters the adjacent output pipe B and pushes open the valve, and then enters the adjacent test tube to preliminarily mix with the stabilizer in the test tube; S5, after the piston plate moves to the last end inside the quantitative piston cylinder, the quantitative blank reagent output is completed, at this time, the electric sliding block drives the moving plate to move forward to reset, with the continuous forward movement of the moving plate, the moving plate first contacts the plurality of reset rings, then the reset rings push the piston rod to move forward to reset, and then the moving frame is pushed to move forward to reset. S6, in the moving frame reset process, rack A through the adjacent gear B drive rotating seat continues to rotate, rotating seat rotates through its top of the bar drive eccentric hole inside the test tube and the supporting block synchronous rotation, and then make the test tube in the stabilizer and blank reagent uniform mixing, and then make a variety of different types of control solution; S7, after the moving frame reset, the electric slide stop moving, then through the supporting frame front top handle supporting frame, and then make the supporting frame drive multiple test tubes forward rotation, until the test tube by adjacent output pipe A under the move, then the multiple test tubes from the multiple eccentric hole inside the draw out; S8, precise measuring test sample and with the blank solution quantitative dilution preparation test sample solution, take quantitative above-mentioned blank solvent, control solution and test sample solution, in turn to high performance liquid chromatograph for sample and record high performance liquid chromatogram, according to each control solution chromatogram in the peak position, attribution test sample chromatogram in each chromatographic peak, so as to judge whether the test sample contains different types of stabilizer.
