However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figure 1-Figure 7 As shown, the utility model provides a bottle-top pipette for detecting animal-derived veterinary drug residues, comprising: a shell 1, a first circular tube 2 is fixedly passed through the bottom of the shell 1, and an adjustment mechanism 3 is provided on the shell 1;

[0029] The adjusting mechanism 3 includes a round rod 301, a limiting ring 304, a first cylindrical hole 305 and two rubber rings 307. The first auxiliary block 302 is fixed to the top of the round rod 301, and the second round tube 303 is fixed to the bottom of the round rod 301. The inner wall of the second round tube 303 is provided with a second cylindrical hole 306. The bottom end of the round rod 301 movably passes through the top of the shell 1, and the second round tube 303 is movably sleeved inside the first round tube 2. The limiting ring 304 is fixedly sleeved inside the shell 1 near the bottom position. The first cylindrical hole 305 is opened on the inner wall of the first round tube 2 near the top position. The interior of the first cylindrical hole 305 and the interior of the second cylindrical hole 306 are both connected to the interior of the shell 1. The two rubber rings 307 are both bonded to the inner wall of the first round tube 2. The round tube 303 is movably sleeved between the insides of the two rubber rings 307, and the opening of the first cylindrical hole 305 is between the two rubber rings 307. The inside of the shell 1 is movably sleeved with a rubber piston 4, and the top of the rubber piston 4 is bonded with a piston handle 5, and the top of the piston handle 5 is fixed with a second auxiliary block 6. The liquid outlet end of the shell 1 is installed with a manual valve 7, and the liquid outlet end of the manual valve 7 is installed with a connecting pipe 8. The bottom of the shell 1 is fixed with an internal threaded tube 9, and the top of the piston handle 5 movably passes through the top of the inner wall of the shell 1. The first round tube 2 is inside the internal threaded tube 9, and the bottom of the rubber piston 4 contacts the top of the limit ring 304. The bottom end of the round rod 301 movably passes through the top of the rubber piston 4, and the round rod 301 is movably sleeved inside one of the through holes of the piston handle 5.

[0030] The effect achieved is that when a bottle-mouth pipette for detecting animal-derived veterinary drug residues is needed, the shell 1 is first installed on the prepared reagent bottle mouth by using the cooperation of the internal threaded tube 9, and then the length of the liquid inlet end of the pipette is adjusted according to the height of the reagent bottle and the liquid level of the reagent inside the reagent bottle. When the height of the reagent bottle is high and the liquid level of the reagent inside the reagent bottle is low, the first auxiliary block 302 is first pressed and moved vertically downward. At this time, the vertically downward moving first auxiliary block 302 will drive the round rod 301 to move vertically downward, and the vertically downward moving round rod 301 will drive the second round tube 303 to move vertically downward. When the second round tube 303 moves to a position where it can no longer move (such as Figure 4When the second auxiliary block 6 is in the state shown in the figure, the first auxiliary block 302 is pressed first, and then the pressing is stopped, at which time the first auxiliary block 302 stops moving vertically downward, and the first auxiliary block 302 that stops moving vertically downward cooperates with the round rod 301 to make the second round pipe 303 stop moving. When the reagent inside the reagent bottle needs to be transferred, the prepared receiving reagent bottle is placed directly below the connecting pipe 8 first, and then a force is applied to the second auxiliary block 6, so that the second auxiliary block 6 moves vertically upward, at which time the second auxiliary block 6 that moves vertically upward cooperates with the piston handle 5 to drive the rubber piston 4 to move vertically upward, and the rubber piston 4 that moves vertically upward is separated from the top of the limiting ring 304, and the rubber piston 4 that moves vertically upward cooperates with the shell 1, the second cylindrical hole 306, the first cylindrical hole 305, the two rubber rings 307, the first round pipe 2 and the second round pipe 303 to make the liquid inlet end of the second round pipe 303 obtain suction, and the liquid inlet end of the second round pipe 303 that obtains suction sucks the reagent inside the reagent bottle and transports it to the inside of the shell 1 through the cooperation of the second cylindrical hole 306, the first cylindrical hole 305, the first round pipe 2, the second round pipe 303 and the two rubber rings 307. When the amount of reagent inside the shell 1 reaches the required amount, the movement of the second auxiliary block 6 is stopped first, at which time the second auxiliary block 6 that stops moving cooperates with the above-mentioned parts to make the second round pipe 303 stop sucking reagent. When the reagent inside the shell 1 needs to be released into the previously placed receiving reagent bottle, the above-mentioned operation steps are reversed first, so that the second round pipe 303 moves vertically upward until the liquid outlet end of the second cylindrical hole 306 contacts the inner wall of one of the rubber rings 307, then the valve of the hand valve 7 is opened, and then the second auxiliary block 6 is pressed and moves vertically downward, at which time the second auxiliary block 6 that moves vertically downward cooperates with the above-mentioned parts to make the rubber piston 4 move vertically downward, at which time the rubber piston 4 that moves vertically downward cooperates with the shell 1, the first cylindrical hole 305, the first round pipe 2, the second round pipe 303, the two rubber rings 307, the connecting pipe 8 and the hand valve 7 with the valve open to make the reagent inside the shell 1 be released into the receiving reagent. When the release operation of the reagent inside the shell 1 is completed, the above-mentioned operation steps are reversed directly. When the height of the reagent bottle is low and the liquid level of the reagent inside the reagent bottle is high, the above-mentioned operation steps are reversed directly to make the second round pipe 303 reset to the original position.

[0031] Working principle: when the animal source veterinary drug residue detection bottle mouth pipette is needed, at this time, the shell 1 is installed on the prepared reagent bottle mouth by the cooperation of the internal thread pipe 9, then the liquid inlet end length of the pipette is adjusted according to the height of the reagent bottle and the liquid level of the reagent in the reagent bottle, when the height of the reagent bottle is higher and the liquid level of the reagent in the reagent bottle is lower, at this time, the first auxiliary block 302 is pressed and vertically moved downward, at this time, the vertically downward moving first auxiliary block 302 drives the round rod 301 to vertically move downward, and the vertically downward moving round rod 301 drives the second circular pipe 303 to vertically move downward, when the second circular pipe 303 moves to the position where it cannot move any more (such as Figure 4When the state shown is reached, the first auxiliary block 302 is stopped from being pressed. At this time, the first auxiliary block 302 stops moving vertically downward. The first auxiliary block 302 that stops moving vertically downward will stop the second round tube 303 from moving under the cooperation of the round rod 301. When the reagent inside the reagent bottle needs to be transferred, the prepared receiving reagent bottle is placed just below the connecting tube 8. Then, a force is applied to the second auxiliary block 6 to make the second auxiliary block 6 move vertically upward. At this time, the second auxiliary block 6 that moves vertically upward will drive the rubber piston 4 to move vertically upward under the cooperation of the piston handle 5, and the rubber piston 4 that moves vertically upward will stop moving vertically. The piston 4 will separate from the top of the limiting ring 304. At the same time, the rubber piston 4 that moves vertically upward will obtain suction at the liquid inlet end of the second circular tube 303 under the cooperation of the shell 1, the second cylindrical hole 306, the first cylindrical hole 305, the two rubber rings 307, the first circular tube 2 and the second circular tube 303. The liquid inlet end of the second circular tube 303 that obtains suction will suck the reagent inside the reagent bottle and transport it to the inside of the shell 1 through the cooperation of the second cylindrical hole 306, the first cylindrical hole 305, the first circular tube 2, the second circular tube 303 and the two rubber rings 307. When the amount of reagent inside the shell 1 reaches the required amount of reagent When the second auxiliary block 6 stops moving, the second auxiliary block 6 that stops moving will stop the second tube 303 from sucking in the reagent under the cooperation of the above-mentioned components. When the reagent inside the shell 1 needs to be released into the previously placed receiving reagent bottle, the above-mentioned operation steps are first performed in reverse order, so that the second tube 303 moves vertically upward until the liquid outlet end of the second cylindrical hole 306 contacts the inner wall of one of the rubber rings 307, and then the valve of the manual valve 7 is opened, and then the second auxiliary block 6 is pressed to move it vertically downward. At this time, the second auxiliary block 6 that moves vertically downward will stop in the above-mentioned With the cooperation of the components, the rubber piston 4 moves vertically downward. At this time, the vertically downward moving rubber piston 4 will release the reagent inside the shell 1 into the receiving reagent with the cooperation of the shell 1, the first cylindrical hole 305, the first circular tube 2, the second circular tube 303, the two rubber rings 307, the connecting tube 8 and the manual valve 7 that opens the valve. When the release operation of the reagent inside the shell 1 is completed, just follow the above-mentioned operation steps in reverse. When the height of the reagent bottle is relatively short and the liquid level of the reagent inside the reagent bottle is relatively high, just follow the above-mentioned operation steps in reverse to restore the second circular tube 303 to its original position.

[0032] The housing 1 , the first circular tube 2 and the second circular tube 303 are all made of transparent materials.

[0033] The distance between the top and bottom of the rubber ring 307 is greater than the diameter of the second cylindrical hole 306 .
