[0018] Through the above technical solution, all the second wedge-shaped sliders can be pressed down by the fourth button to move all the second movable plates, so that the second latch tongue is separated from the second latch block.

[0020] Through the above technical solution, through the use of the lifting mechanism, when the reagent tube is inserted into the outer shell, the hydraulic oil in the cylinder can enter the cavity through the first oil hole, and then be discharged into the cylinder above the movable piston through the second oil hole, so that the pressure on both sides of the movable piston is balanced, so that the push plate can move down quickly. When the locking mechanism is unlocked, the spring pushes the push plate up. At this time, the movable piston moves down compared to the push rod, blocking the first oil hole, so that the hydraulic oil in the upper part of the cylinder can only flow into the lower part of the cylinder through the through hole. Since the diameter of the through hole is small, the pressure above and below the cylinder cannot be balanced quickly. Therefore, the movable piston will give resistance to the push plate, so that the push plate will not rise quickly, avoiding the push plate from bouncing up quickly and bouncing up the reagent tube.
[0021] The beneficial effects of the present invention are as follows: (1) The present invention uses a locking mechanism to insert the plug on the reagent tube into the second square hole and the third square hole, and respectively clamps the first clamp block and the second clamp block through the first clamp tongue and the second clamp tongue, thereby fixing the reagent tube in the shell and improving the stability of the reagent tube. When performing anti-DNA antibody detection, the reagent tube needs to be repeatedly plugged in and out. If the reagent tube can be rotated at will, it is easy to cause the cover of the adjacent reagent tube to touch the tube mouth of another reagent tube and cause contamination. By setting the anti-fool protrusion on the anti-fool plate, the orientation of the reagent tube can be consistent, avoiding the wrong direction of the reagent tube; (2) The present invention uses a lifting mechanism. When the reagent tube is inserted into the shell, the hydraulic oil in the cylinder can enter the cavity through the first oil delivery hole, and then be discharged into the cylinder on the upper part of the movable piston through the second oil delivery hole, thereby balancing the pressure on both sides of the movable piston and allowing the push plate to move down quickly. When the locking mechanism is unlocked, the spring pushes the push plate up. At this time, the movable piston moves down compared to the push rod, and the second piston is pushed down. An oil delivery hole is blocked, so that the hydraulic oil in the upper part of the cylinder can only flow into the lower part of the cylinder through the through hole. Due to the small diameter of the through hole, the pressure of the upper and lower parts of the cylinder cannot be quickly balanced. Therefore, the movable piston will give resistance to the push plate, so that the push plate will not rise quickly, and avoid the push plate from quickly bouncing up the reagent tube, thereby causing the anti-DNA antibody detection solution to bounce up and splash; (3) The present invention is provided with the first button, the second button, the third button and the fourth button. When it is necessary to take a reagent tube in a row or column, it is only necessary to press the first button and the third button of the corresponding row and column number to unlock the corresponding reagent tube locking mechanism separately, so that the reagent tube is lifted up under the action of the lifting mechanism, so that the operator can take it from the side of the tube body without having to take it from the top, effectively solving the problem that the reagent tube mouth is easily contaminated, and greatly improving the accuracy of the test. When it is necessary to unlock all the reagent tubes, it is only necessary to press the second button and the fourth button to drive all the locking mechanisms to unlock, so that all the reagent tubes can be removed for color development and quantification.

The second movable plate 516 is provided with a third hole 517 near the second wedge-shaped slider 524. The second wedge-shaped slider 524 is slidably connected to the third hole 517. The third button 525 is slidably connected to the second shell 52. The third button 525 drives the second wedge-shaped slider 524 to move downward along the second guide rod 521. The second wedge-shaped slider 524 cooperates with the third hole 517 to push the second movable plate 516 to move. The second movable plate 516 drives the second latch 519 to disengage from the second block 26.
[0032] A pair of third springs 520 are fixedly connected to one end of the second movable plate 516 away from the third hole 517, and the pair of third springs 520 are fixedly connected to the housing 1. A plurality of fourth square holes 518 are opened on the second movable plate 516. A second latch 519 is fixedly connected to the side of the fourth square hole 518 near the third spring 520.

The second fork plates 526 drive all the second wedge-shaped sliders 524 to move downward, thereby moving all the second movable plates 516 and causing the second latch 519 to disengage from the second blocking block 26.
[0033] like Figure 13-15As shown, a plurality of lifting mechanisms 8 are fixedly connected to the lower surface of the shell 1, and the lifting mechanism 8 includes a cylinder 81 fixedly connected to the inner bottom wall of the shell 1, and a fifth spring 82 is provided on the outer sleeve of the cylinder 81, and the upper end of the fifth spring 82 is fixedly connected to a push plate 83, and the lower end of the push plate 83 is fixedly connected to a push rod 84, and a cavity 85 is provided at the lower end of the push rod 84, and a first oil delivery hole 86 is provided at the lower end of the push rod 84, and a second oil delivery hole 87 is provided at the upper end of the push rod 84 near the cavity 85, and a second limiting ring 810 is fixedly connected to the push rod 84, and a pair of first limiting rings 88 are fixedly connected to the push rod 84, and a movable piston 811 is provided between the pair of first limiting rings 88, and the push rod 84 passes through and slides to connect the movable piston 811, and the upper and lower sides of the movable piston 811 are fixedly connected to a second sealing ring 813, and the inner sides of the pair of first limiting rings 88 are fixedly connected to The first sealing ring 89 and the movable piston 811 are provided with several through holes 812. The fifth spring 82 pushes the push plate 83 to move upward. At this time, the push plate 83 drives the push rod 84 to move upward. The first limiting ring 88 on the push rod 84 drives the movable piston 811 to move upward. The movable piston 811 first moves to the bottom of the push rod 84 under the resistance of the hydraulic oil, blocking the first oil delivery hole 86, so that the hydraulic oil can only flow through the through hole 812. Since the diameter of the through hole 812 is small, the pressure difference between the upper and lower parts of the cylinder 81 cannot be balanced quickly, so it will form resistance to the movable piston 811, so that the movable piston 811 pulls the push rod 84, and the push rod 84 pulls the push plate 83, reducing the rising speed of the push plate 83, so that the push plate 83 will not be lifted quickly, avoiding the reagent tube 2 from flying away, and the first sealing ring 89 and the second sealing ring 813 are squeezed and fitted against each other to achieve sealing.
[0034] The working principle of this embodiment is as follows: the experimenter selects the required reagent tube 2, inserts the reagent tube 2 into the circular hole 4 on the first fixed plate 3, aligns the groove 24 on the plug 23 with the anti-foolproof protrusion 9 on the anti-foolproof plate 6, then the first clamping block 25 pushes away the first clamping tongue 56, and the second clamping block 26 pushes away the second clamping tongue 519, and presses the push plate 83 down through the plug 23.
[0035] At this time, the push plate 83 pushes the push rod 84 to move downward, and the push rod 84 pushes the movable piston 811 to move downward through the first limit ring 88. The hydraulic oil in the cylinder 81 enters the cavity 85 through the first oil hole 86, and then flows into the cylinder 81 above the movable piston 811 through the second oil hole 87. Since the first oil hole 86 and the second oil hole 87 have larger diameters, the pressure at the upper and lower ends of the cylinder 81 can be quickly balanced, so that the movable piston 811 has no downward resistance, so that the push plate 83 can be easily pressed down.
[0036] Then the first spring 57 pushes the first movable plate 53, and the first movable plate 53 drives the first latch 56 to clamp the first block 25. The third spring 520 pushes the second movable plate 516, and the second movable plate 516 drives the second latch 519 to clamp the second block 26, thereby locking the reagent tube 2.
[0037] When it is necessary to take the reagent tube 2 in a certain row or column, first press the first button 512 and the third button 525 corresponding to the row and column numbers. At this time, the first button 512 drives the first wedge-shaped slider 511 to move down along the first guide rod 58, and the first wedge-shaped slider 511 cooperates with the first square hole 54 to push the first movable plate 53 to move, so that the first tongue 56 disengages from the first block 25. The third button 525 drives the second wedge-shaped slider 524 to move down along the second guide rod 521, and the second wedge-shaped slider 524 cooperates with the third hole 517 to push the second movable plate 516 to move. The second movable plate 516 drives the second tongue 519 to disengage from the second block 26, so that the lifting mechanism 8 can push the reagent tube 2 to rise.
[0038] The fifth spring 82 pushes the push plate 83 upward. At this time, the push plate 83 drives the push rod 84 upward. The first limit ring 88 on the push rod 84 drives the movable piston 811 upward. The movable piston 811 first moves to the bottom of the push rod 84 under the resistance of the hydraulic oil, blocking the first oil delivery hole 86, so that the hydraulic oil can only flow through the through hole 812. Since the diameter of the through hole 812 is small, the pressure difference between the upper and lower parts of the cylinder 81 cannot be balanced quickly, so it will form resistance to the movable piston 811, so that the movable piston 811 pulls the push rod 84, and the push rod 84 pulls the push plate 83, reducing the rising speed of the push plate 83, so that the push plate 83 will not be lifted up quickly, thereby avoiding the reagent tube 2 from flying off.
[0039] When all the reagent tubes 2 need to be unlocked, press the second button 515 and the fourth button 528. The second button 515 drives the first fork plate 513 to move downward through the first connecting plate 514. The first fork plate 513 drives all the first wedge-shaped sliders 511 to move downward, thereby moving all the first movable plates 53 and disengaging the first latch 56 from the first block 25. The fourth button 528 drives the second fork plate 526 to move downward through the second connecting plate 527. The second fork plate 526 drives all the second wedge-shaped sliders 524 to move downward, thereby moving all the second movable plates 516 and disengaging the second latch 519 from the second block 26, thereby unlocking all the reagent tubes 2.
