The end of the output shaft of the reduction motor 814 is fixed with a driving shaft 815 that passes through the vertical plate 81. The reduction motor 814 is electrically connected to an external power supply and is controlled by a control switch, which can drive the driving shaft 815 to rotate slowly. A driving hollow rod 816 is fixed to the surface of the driving shaft 815, and the inner wall of the driving hollow rod 816 is slidably installed. There is an adjusting rod 817, and the adjusting rod 817 and the driving hollow rod 816 are fixed together by a locking unit 818. The length of the adjusting rod 817 in the driving hollow rod 816 is adjustable, so as to control the upward movement distance of the lifting plate 86, and then the stroke of the delivery piston 84 can be adjusted, and the amount of reagent absorbed by the delivery cylinder 83 can be controlled, so as to selectively use the reagent bottles 7 of different capacities, and only the length of the adjusting rod 817 needs to be controlled. The adjusting rod 817 will not contact the front and rear of the lifting plate 86 during the rotation, and the end of the adjusting rod 817 is always located below the lifting plate 86.

[0028] In this embodiment, the locking unit 818 includes a mounting block 8181 fixed on the surface of the driving hollow rod 816, a locking screw 8182 is threadedly penetrated between the mounting block 8181 and the driving hollow rod 816, a threaded rod 8183 is fixed on the surface of the locking screw 8182, a locking groove 8184 is provided on the surface of the adjusting rod 817, and the inner wall of the locking groove is provided with a resistance increasing layer 8185 used in conjunction with the locking screw 8182, and the end of the locking screw 8182 is squeezed and contacted with the resistance increasing layer 8185 to achieve the positioning of the adjusting rod 817.

[0029] In this embodiment, the synchronous propulsion unit 9 includes a driving box 91 fixed on the left bracket 3, a push rod 92 is slidably penetrated on the driving box 91, a spring block 93 is fixed on the support plate 10, the push rod 92 is slidably penetrated on the spring block 93, a shift block 94 is fixed at one end of the push rod 92, a return spring 95 is fixed between the shift block 94 and the spring block 93, the setting of the return spring 95 is convenient for the push rod 92 to drive the shift block 94 to reset quickly, a horizontal shift rod 96 used in conjunction with the shift block 94 is fixed on the surface of the driving hollow rod 816, a rotating shaft 97 is rotatably penetrated on the side of the driving box 91, there is a certain damping between the rotating shaft 97 and the driving box 91, the end of the rotating shaft 97 is fixed to the center of the left belt roller 4, and a conveying ratchet 98 is fixed on the surface of the rotating shaft 97. A rocker arm 99 is rotatably mounted on the end of the rotating shaft 97, and a connecting block 910 is rotatably mounted on the rocker arm 99. The connecting block 910 is rotatably connected to the push rod 92. A pawl 911 used in conjunction with the conveying ratchet 98 is also rotatably mounted on the rocker arm 99. A protruding rod 912 is fixed on the pawl 911 and the rocker arm 99, and a tension spring 913 is fixed between the two protruding rods 912. There is a certain damping between the belt roller 4 and the bracket 3, thereby ensuring that each time the belt roller 4 rotates, the conveying belt 5 will not move too far due to inertia, and that each time the shifting block 94 leaves the shifting block 94, the shifting block 94 will not continue to move, thereby ensuring that the angle of each rotation of the conveying ratchet 98 is consistent, so that the distance that the conveying belt 5 moves backward each time is just the distance between the center points of the two accommodating circles 6.

[0030] In this embodiment, a retaining ring 914 is fixed on the surface of the push rod 92. The retaining ring 914 is used to limit the push rod 92 so that the position of the push rod 92 is constant after each rebound. A retaining rod 915 is fixed on the rocker arm 99 to limit the pawl 911. The tension spring 913 is set to facilitate the rapid resetting of the pawl 911 and contact with the retaining rod 915.

[0031] In this embodiment, the surface of the adjusting rod 817 is provided with scale lines 11, and the scale lines 11 can be used to observe the extended length of the adjusting rod 817, and then the displacement distance of the delivery piston 84 can be intuitively seen. The resistance increasing layer 8185 is made of frosted material. During canning, the bottom end of the pressing tube 812 is located above the mouth of the reagent bottle 7.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] During operation, the reduction motor 814 is started, thereby driving the entire driving hollow rod 816 to rotate slowly clockwise (left view), and then the horizontal lever 96 squeezes the lever block 94 to drive the entire push rod 92 to slide backward, and then the entire swing rod 99 is pushed to rotate around the rotating shaft 97 through the connecting block 910, and then the entire conveying ratchet 98 is pushed to rotate through the ratchet 911, so that the rotating shaft 97 drives the rear belt roller 4 to rotate, so that the entire conveying belt 5 is transported backward, so that the frontmost reagent bottle 7 is just located below the pressure tube 812. At this time, the horizontal lever 96 is separated from the lever block 94, driving the hollow rod 816 to continue to rotate, and the adjusting rod 817 rotates and pushes the lifting plate 86 upward, and then the entire conveying piston 84 is driven to move upward through the connecting rod 85. Under the action of negative pressure, the conveying piston 84 sucks the reagent inside the storage tank 2 into the conveying cylinder 83 through the suction pipe 810. Until the adjusting rod 817 rotates to a vertical state, at this time, the upward movement distance of the lifting plate 86 reaches the maximum, and the adjusting rod 817 continues to rotate. At this time, the lifting plate 86 is driven downward by the elastic force of the canning spring 89, and then the delivery piston 84 is driven downward until the adjusting rod 817 is separated from the bottom of the lifting plate 86, and the delivery piston 84 presses the reagent in the delivery cylinder 83 into the reagent bottle 7 through the pressure tube 812 for canning, and then repeats the above steps to perform continuous quantitative canning. When replacing different reagent bottles 7, if the canning volume needs to be increased, the locking screw 8182 needs to be loosened, the adjusting rod 817 needs to be pulled outward, and then the locking screw 8182 needs to be tightened to position it, thereby increasing the stroke of the delivery piston 84 and increasing the canning volume. Anyway, when reducing the canning volume, shortening the distance that the adjusting rod 817 is extended can reduce the stroke of the delivery piston 84 and thereby reduce the canning volume.
