[0030] The supporting mechanism 4 is arranged on the outer side of the top of the fixing mechanism 2 and is used to support and fix the inner wall of the test tube rack 3 .

[0031] In order to conveniently place and fix the test tube rack 3, as shown in FIG. Figure 1-Figure 3As shown, the fixing mechanism 2 includes a fixing shaft 201, a placing plate 203 is fixedly installed on the outer bottom of the fixing shaft 201, and clamping plates 204 are rotatably installed around the outer wall of the placing plate 203. The placing plate 203 can place the test tube rack 3, and the four clamping plates 204 can clamp and fix the outer wall of the test tube rack 3.

[0032] In order to keep the test tube rack 3 stable during the oscillation process, Figure 1-Figure 2 and Figure 4 As shown, the supporting mechanism 4 includes a rotating plate 401, which is rotatably sleeved on the top outer side of the fixed shaft 201, and a fastening pin 405 is provided between the inner wall of the rotating plate 401 and the inner wall of the top of the fixed shaft 201, and traction plates 402 are rotatably installed on all four sides of the top of the rotating plate 401, and support plates 403 are rotatably installed on the bottom of one end of the four traction plates 402 away from the rotating plate 401, and the four support plates 403 are movably connected to the inner wall of the test tube rack 3. The rotation of the rotating plate 401 is pulled by the traction of the traction plate 402, so that the support plate 403 can support the inner wall of the test tube rack 3, thereby keeping the test tube rack 3 stable during the oscillation process.

[0033] In order to keep the rotating plate 401 stable after adjustment, Figure 1-Figure 4 As shown, the fixing mechanism 2 includes a fixing hole 202, which is opened on the inner wall at the top of the fixing shaft 201, and the inner wall of the fixing hole 202 is threadedly connected to the bottom of the outer wall of the fastening pin 405, and the top of the outer wall of the fastening pin 405 away from the fixing hole 202 is movably connected to the inner wall of the rotating plate 401, and the screw head part of the fastening pin 405 is in contact with the top of the rotating plate 401. The threaded connection between the fastening pin 405 and the fixing hole 202 can fix the adjusted rotating plate 401, so that the adjusted rotating plate 401 remains stable, and the support plate 403 can be prevented from loosening during the process of supporting the test tube rack 3.

[0034] In order to keep the support plate 403 stable during the movement, Figure 1-Figure 4 As shown, the fixing mechanism 2 includes a movable groove 205, and four movable grooves 205 are provided. The four movable grooves 205 are equidistantly arranged in a ring shape on the inner wall around the placement plate 203. Sliders 404 are fixedly installed at the bottom of the four support plates 403.

[0035] In order to ensure that the clamping plate 204 and the supporting plate 403 can stably fix the test tube rack 3, as shown in FIG. Figure 2-Figure 4As shown, the front vertical section of the clamping plate 204 is set to an inverted L-shaped structure, and the cross section of the support plate 403 in a top view is set to a fan-shaped structure. The clamping plate 204 with the L-shaped structure can clamp the outer wall of the test tube rack 3, and the support plate 403 with the fan-shaped structure can support the inner wall of the test tube rack 3, so that the test tube rack 3 remains stable during the oscillation process.

[0036] During the food testing process, it is necessary to fully mix the sample and reagent in the test tube, and then select a suitable test tube rack 3 according to the needs and place it on the top of the placement plate 203, and then rotate the four clamping plates 204 to rotate it from a horizontal state to a vertical state and clamp and fix the outer wall of the test tube rack 3, and then rotate the rotating plate 401 to make it rotate on the top outside of the fixed shaft 201, and then under the traction of the four traction plates 402, the four support plates 403 can be driven to expand outward or contract inward, so that the four support plates 403 can support the inner wall of the test tube rack 3, and at the same time, the movable groove 205 can limit the movement of the slider 404, so that the support plate 403 remains stable during the movement. After that, a fastening pin 405 is used to penetrate the inner wall of the rotating plate 401 and be threadedly connected with the inner wall of the fixing hole 202, so that the adjusted rotating plate 401 can be fixed, so that the adjusted supporting plate 403 can stably support the test tube rack 3, thereby preventing it from loosening, so that the test tube rack 3 remains stable during the oscillation and mixing process, and the vortex mixer body 1 can drive the fixing mechanism 2 to oscillate, so that the test tube placed on the inner wall of the test tube rack 3 can be oscillated, so that the food sample inside can be fully mixed with the reagent, which can improve the accuracy of food detection. This embodiment specifically solves the problem that the test tube fixing rack cannot be conveniently installed and replaced according to needs in the prior art, and the test tube fixing rack is easy to move during the oscillation process.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
