[0022] In this embodiment, the inner wall of the transfer bin 36 is fixedly connected with a fixing plate 313, the upper end of the fixing plate 313 is fixedly connected with a mounting rod 314, the upper end of the mounting rod 314 is fixedly connected with a spoiler block 315, the outer side of the spoiler block 315 is fixedly connected with a spiral frame 316, the inner side of the connecting member 34 is fixedly connected to the outer side of the transfer bin 36, the connecting pipe 35 is located on the inner side of the control frame 33, the main body of the connecting pipe 35 is made of a rubber hose, and the position of the collecting beaker 31 The connecting tube 35 is placed at a position higher than the sampling beaker 38, the rear end of the clamping plate 310 is in contact with the front end of the connecting tube 35, there are two groups of the pushing rod 39, the clamping plate 310, the docking rod 311 and the finger ring 312, the spoiler block 315 is truncated cone-shaped, the connecting tube 35 is connected to the collecting beaker 31, the connecting tube 35 is connected to the transfer bin 36, the transfer bin 36 and the delivery tube 37 are connected, and the delivery tube 37 is located directly above the sampling beaker 38.

[0023] Specifically, the chemical reagent liquid in the inner side of the collection beaker 31 flows into the connecting tube 35, and the chemical reagent liquid flows into the transfer bin 36 along the connecting tube 35, and the chemical reagent liquid first contacts the spoiler block 315, so that the spoiler block 315 pushes the chemical reagent liquid to the four groups, and the chemical reagent liquid slowly rotates and flows downward along the spiral frame 316. At this time, the chemical reagent liquid flows into the sampling beaker 38 along the delivery pipe 37. After a certain amount of chemical reagent liquid is taken out from the inner side of the sampling beaker 38, the experimenter puts two fingers into the inner side of the two groups of finger rings 312, and pulls the two groups of finger rings 312 inward with two fingers, so that the two groups of push rods 39 move toward each other, and the two groups of clamping plates 310 clamp the connecting tube 35, so as to block the connecting tube 35, so that the chemical reagent liquid in the inner side of the collection beaker 31 no longer flows downward, and then a certain amount of chemical reagent liquid can be taken out.

[0024] In this embodiment, the lower end of the support base 1 is fixedly connected with support legs 2 . There are four groups of support legs 2 , and the four groups of support legs 2 are distributed at the four corners of the lower end of the support base 1 .

[0025] Specifically, the collecting beaker 31 is installed on the upper end of the supporting base 1, and the supporting base 1 is supported by four groups of supporting legs 2, so that the supporting base 1 can lift the collecting beaker 31 through the supporting legs 2, and there is a height difference between the collecting beaker 31 and the sampling beaker 38.

[0026] Working principle:

[0027] When in use, the experimenter first fills the collecting beaker 31 with chemical reagent liquid. Since the collecting beaker 31 is installed at the upper end of the support base 1, and the support base 1 is supported by four groups of supporting legs 2, the support base 1 lifts the collecting beaker 31 through the supporting legs 2, and there is a height difference between the collecting beaker 31 and the sampling beaker 38, so that the chemical reagent liquid in the inner side of the collecting beaker 31 flows into the connecting tube 35, and the chemical reagent liquid flows into the transfer bin 36 along the connecting tube 35, and the chemical reagent liquid first contacts the spoiler block 315, so that the spoiler block 315 pushes the chemical reagent liquid to the four groups, and the chemical reagent liquid slowly rotates and flows downward along the spiral frame 316. At this time, the chemical reagent liquid flows along the delivery pipe 37 into the sampling beaker 38. After taking out a certain amount of chemical reagent liquid from the inner side of the sampling beaker 38, the experimenter puts two fingers into the inner side of the two groups of finger rings 312, and pulls the two fingers inward. By moving the two groups of finger rings 312, the two groups of push rods 39 move toward each other, and the two groups of clamping plates 310 clamp the connecting tube 35, so as to block the connecting tube 35, so that the chemical reagent liquid in the inner side of the collecting beaker 31 does not flow downward, and a certain amount of chemical reagent liquid can be taken out. By pulling the two groups of finger rings 312 inward, the two groups of push rods 39 move toward each other, and the two groups of clamping plates 310 clamp the connecting tube 35, the purpose of blocking the connecting tube 35 can be achieved, so that the chemical reagent liquid in the inner side of the collecting beaker 31 does not flow downward, and a certain amount of chemical reagent liquid can be taken out. Secondly, the chemical reagent liquid flows along the connecting tube 35 into the transfer bin 36, and the chemical reagent liquid first contacts the spoiler block 315, so that the spoiler block 315 pushes the chemical reagent liquid to the four groups, and the chemical reagent liquid slowly rotates and flows downward along the spiral frame 316, so as to avoid the chemical reagent liquid flowing downward quickly and causing splashing.
