[0021] The fixing member 6 is composed of a connecting plug 61, a limiting ring 1 62, multiple movable blocks 63, a movable cover 64 and an elastic column 65. The cover plate 5 is provided with two through holes 1, and the quantitative disk 1 is provided with two through holes 2. The through holes 1 and 2 are symmetrically distributed.

[0022] The connecting plug 61 passes through through hole 1 and through hole 2 and is slidably connected with through hole 1 and through hole 2. The limiting ring 1 62 is fixedly installed on the connecting plug 61. The limiting ring 1 62 contacts the outer wall of the cover plate 5. The connecting plug 61 is provided with a plurality of through openings 1. A plurality of movable blocks 63 are movably installed on the plurality of through openings 1 respectively. The movable blocks 63 are adapted to the through openings 1.

[0024] The elastic column 65 is slidably installed in the connecting plug 61 . The elastic column 65 is matched with a plurality of movable blocks 63 . The length of the elastic column 65 is slightly longer than the total length of the connecting plug 61 and the limiting ring 1 62 .

[0025] Four fixing cylinders 7 are fixedly mounted on the quantitative disk 1 .

[0026] The working principle of the optical capillary quantitative tooling with quantitative function provided by the utility model is as follows:

[0027] The first step: using a transparent or translucent capillary tube 2, installing the translucent capillary tube 2 on a quantitative disk 1 with a placement groove on the surface, installing a plurality of groove-type photoelectric switches 3 at the required position, and the installation position of the photoelectric switch 3 is eccentrically installed, so that a basic quantitative unit is made. When multiple volume quantification is required, multiple quantitative units can be combined to work together, making the operation simple. The eccentric installation solves the interference of the reagent (liquid) color on the system, and can achieve quantification of liquids of any color. Because the capillary quantification is adopted, the quantification of liquids with a volume of less than 0.5 ml can be solved. At the same time, multiple units can be combined by applying the installation method of the quantitative unit to achieve efficient quantification of multiple volumes. At the same time, the quantitative method of installing the groove-type photoelectric switch can effectively identify the problem of bubbles generated during the quantitative process;

[0028] Step 2: The quantitative disk 1 and the cover plate 5 can be conveniently disassembled and fixed by the fixing member 6. The connecting plug 61 passes through the through hole 1 on the cover plate 5 and the through hole 2 on the quantitative disk 1. During this period, the movable block 63 is movably connected, so the movable block 63 is moved and stored in the connecting plug 61. When the limit ring 1 62 contacts the cover plate 5, the elastic column 65 is inserted into the connecting plug 61 through the through hole 3, and then the movable cover 64 is slid and closed onto the through hole 3 on the limit ring 1 62. Because the length of the elastic column 65 is longer than that of the connecting plug 61 and The total length of the limiting ring 62 is a little longer, because when the movable cover 64 is closed, the elastic column 65 is in a compressed state. Therefore, when the movable cover 64 is closed, the elastic column 65 will squeeze the movable cover 64, so that the movable cover 64 can be prevented from leaving the through hole 3 at will. At the same time, the movable block 63 will be squeezed by the elastic column 65 and will come out of the through hole 1, so as to contact the outer wall of the quantitative disk 1, so as to limit and fix the quantitative disk 1 and the cover plate 5. In the same way, they can be disassembled, which makes the operation simple and convenient for later disassembly and maintenance.
