[0033] It should be noted that the meter body 1 is a moisture meter in the prior art for testing moisture, and its working principle will not be described in detail herein.

[0034] Please refer to Figure 3 , for the convenience of installation and disassembly and use, the installation mechanism 2 in this embodiment includes a three-way valve cover 201 sleeved on the outer surface of the connecting tube 7, three insertion tubes 209 installed on the upper surface of the three-way valve cover 201, boxes 202 fixed on the left and right sides of the three-way valve cover 201, and a fixing component provided inside the boxes 202; the fixing component is used for fixing the three-way valve cover 201. The three-way valve cover 201 is U-shaped, and the three insertion tubes 209 are respectively used to connect with the reagent bottle 5, the reagent tube 6, and the reaction tube 8.

[0035] The fixing component includes two fixing rods 203 fixed between the left and right sides of the inner cavity of the box 202, a first spring 204 sleeved on the outer surface of the fixing rod 203, a moving plate 205 slidably connected to the outer surface of the fixing rod 203, a first pull rod 206 fixed on the front surface of the moving plate 205, a clamping block 207 fixed on the opposite sides of the two moving plates 205, and clamping grooves 208 opened on the left and right sides of the connecting tube 7. The moving plate 205 is reset by the first spring 204, and the moving plate 205 is driven to move by the first pull rod 206.

[0036] Among them, a sliding hole is opened on the front surface of the box 202, and the first pull rod 206 is slidably connected inside the sliding hole to facilitate the first pull rod 206 to drive the moving plate 205 to move. The clamping block 207 is slidably connected inside the clamping groove 208 for fixing the three-way valve cover 201.

[0037] In addition, the opposite sides of the left and right first springs 204 are respectively fixed to the opposite sides of the two moving plates 205, and the opposite sides of the left and right first springs 204 are respectively fixed to the opposite sides of the inner cavities of the two boxes 202. The first springs 204 are used to reset the moving plates 205, driving the clamping blocks 207 to snap into the inside of the clamping grooves 208 to fix the connecting pipe 7 and the three-way valve cover 201.

[0038] It should be noted that the connector 4 above the left reagent bottle 5 is connected to the left end cannula 209 through a pipeline, the pipeline on the upper surface of the reagent tube 6 is connected to the front end cannula 209, the pipeline on the left side of the upper surface of the reaction tube 8 is connected to the right end cannula 209, and the connector 4 above the right reagent bottle 5 is connected to the right side of the upper surface of the reaction tube 8 through a pipeline.

[0039] In the installation mechanism 2 of this embodiment, by pulling the first pull rod 206, the moving plate 205 and the clamping block 207 are driven to move together and compress the first spring 204. The three-way valve cover 201 is sleeved on the outer surface of the connecting pipe 7. When the first pull rod 206 is released, the moving plate 205 resets, causing the clamping block 207 to snap into the inside of the clamping groove 208 to fix the three-way valve cover 201 and the connecting pipe 7.

[0040] Please refer to Figure 4 , in order to install the connector 4, the limiting mechanism 3 in this embodiment includes an installation groove 301 opened on the lower surface of the connector 4, two grooves 302 opened inside the connector 4 and communicating with the installation groove 301, expansion rods 303 fixed to the opposite sides of the inner cavities of the two grooves 302, second springs 304 sleeved on the outer surfaces of the expansion rods 303, moving blocks 305 fixed to the opposite sides of the two expansion rods 303, a second pull rod 306 fixed to the lower surface of the moving block 305, and a fixing plate 307 fixed to the opposite sides of the two moving blocks 305; the fixing plate 307 is U-shaped. The second springs 304 are made to perform linear compression movements through the expansion rods 303. Through the expansion rods 303, it is prevented that the second springs 304 deviate during operation, affecting the use of the second springs 304. The moving blocks 305 are reset through the second springs 304, and the moving blocks 305 are driven to move through the second pull rod 306.

[0041] Among them, the inner surface of the fixing plate 307 abuts against the outer surface of the reagent bottle 5 for fixing the reagent bottle 5.

The moving blocks 305 are reset through the second springs 304, driving the fixing plate 307 to move to clamp and fix the reagent bottle 5.

[0042] In the limiting mechanism 3 of this embodiment, when the second pull rod 306 is pulled, the moving block 305 and the fixing plate 307 are driven to move together and compress the second spring 304. The reagent bottle 5 is inserted into the installation groove 301. When the second pull rod 306 is released, the moving block 305 resets, and the fixing plate 307 clamps and fixes the reagent bottle 5.

[0043] The working principle of the above embodiment is as follows:

[0044] (1) When the two first pull rods 206 are pulled away from each other, the first pull rods 206 drive the moving plate 205 to slide on the outer surface of the fixed rod 203 and compress the first spring 204. When the moving plate 205 moves, it will drive the clamping block 207 to move together. At this time, the three-way valve cover 201 is sleeved on the outer surface of the connecting pipe 7. When the first pull rod 206 is released, the moving plate 205 will reset under the action of the first spring 204, driving the clamping block 207 to move, so that the clamping block 207 is inserted into the inner part of the clamping groove 208, fixing the three-way valve cover 201 and the connecting pipe 7, facilitating the quick disassembly and assembly of the three-way valve cover 201. And through the three-way valve cover 201, the solution to be detected and the detection reagent can enter the connecting pipe 7, enter the reaction pipe 8 through the connecting pipe 7, and be detected by the measuring instrument body 1.

[0045] (2) When the two second pull rods 306 are pulled away from each other, the second pull rods 306 drive the moving block 305 to move in the groove 302 and compress the second spring 304 and the telescopic rod 303. When the moving block 305 moves, it will drive the fixing plate 307 to move together. At this time, the reagent bottle 5 is inserted into the installation groove 301. When the second pull rod 306 is released, the moving block 305 will reset under the action of the second spring 304, driving the fixing plate 307 to move, so that the fixing plate 307 clamps and fixes the reagent bottle 5, facilitating the quick disassembly and assembly of the reagent bottle 5.
