[0029] Specifically, the surface of the mounting frame 5 and the two sides of the electric telescopic rod 6 are both installed with limiting slide rails 8 , and the moving block 7 is slidably connected to the surface of the limiting slide rails 8 .

[0030] In a specific embodiment of the present utility model, by providing the limiting slide rail 8, the moving track of the moving block 7 can be limited when the moving block 7 moves, and the stability of the moving block 7 when moving is increased.

[0031] Specifically, the number of teeth on the surface of the first gear 2 is equal to one fourth of the number of teeth on the surface of the second gear 3 .

[0032] In a specific embodiment of the present invention, by setting the number of teeth of the first gear 2 and the second gear 3, one rotation of the first gear 2 will drive the second gear 3 to rotate a quarter of a rotation, thereby achieving replacement of the test tube.

[0034] In a specific embodiment of the utility model, when the second servo motor 1206 is started, its output shaft drives the threaded rod 1203 to rotate, and the rotation of the threaded rod 1203 drives the internal thread push block 1204 and the first clamping plate 1205 to move, thereby moving the sampling tank to the bottom of the sampling tube 11.

[0035] Specifically, the first clamping plate 1205 and the second clamping plate 1207 are both arc-shaped with openings facing inwards, and both the first clamping plate 1205 and the second clamping plate 1207 are rubber pads.

[0037] Specifically, the limiting mechanism 15 includes a limiting frame 1501 installed on the surface of the second gear 3, a first spring telescopic rod 1502 is installed inside the limiting frame 1501, a support plate 1503 is installed on the top of the first spring telescopic rod 1502, a plurality of second spring telescopic rods 1504 are rotatably connected to the surface of the supporting plate 1503, and one end of the outer side of the second spring telescopic rod 1504 is rotatably connected to the surface of the limiting frame 1501, and a limiting block 1505 is installed on the surface of the second spring telescopic rod 1504.

[0038] In a specific embodiment of the utility model, when the test tube contacts the support plate 1503, the force will be transmitted to the support plate 1503. At this time, the support plate 1503 descends and charges the first spring telescopic rod 1502 and the second spring telescopic rod 1504. At the same time, the second spring telescopic rod 1504 will drive the limit block 1505 to clamp and limit the test tube.

[0040] In a specific embodiment of the present invention, the first servo motor 4 , the electric telescopic rod 6 and the electric push rod 9 are conveniently controlled by setting the control terminal 16 .

[0041] Working principle: first, the sampling tank is placed on the surface of the clamping base 1201, and then the second servo motor 1206 is started. The output shaft of the second servo motor 1206 drives the threaded rod 1203 to rotate. The rotation of the threaded rod 1203 drives the internal threaded push block 1204 and the first clamping plate 1205 to move, so as to move the sampling tank to the bottom of the sampling tube 11. Then, the extended end of the electric telescopic rod 6 drives the moving block 7 to move, and then the sampling tube 11 is driven by the electric push rod 9 to start working, so as to take out the styrene in the sampling tank. Then, the output shaft of the first servo motor 4 drives the first gear 2 and the second gear 3 to rotate. At this time, After styrene is poured into the test tube through the sampling tube 11, the first gear 2 and the second gear 3 continue to rotate. By setting the number of teeth of the first gear 2 and the second gear 3, one rotation of the first gear 2 will drive the second gear 3 to rotate a quarter of a turn, thereby realizing the replacement of the test tube. At the same time, when the test tube contacts the support plate 1503, the force will be transmitted to the support plate 1503. At this time, the support plate 1503 descends and charges the first spring telescopic rod 1502 and the second spring telescopic rod 1504. At the same time, the second spring telescopic rod 1504 will drive the limit block 1505 to clamp and limit the test tube, thereby reducing the probability of the test tube being offset during movement.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
