[0021] As shown in the attached Figure 1 、attached Figure 2 figures, the color developing liquid mixing device of the present utility model includes a base 1, a loading platform 2 is connected to the base 1, a first cavity 21, a second cavity 22 and a third cavity 23 are formed in the loading platform 2, the first cavity 21 and the second cavity 22 are respectively communicated with the upper surface of the loading platform 2, a first liquid storage box 3 is detachably installed in the first cavity 21, a second liquid storage box 4 is detachably installed in the second cavity 22, the first liquid storage box 3 and the second liquid storage box 4 are used for storing different reagents, and upper film layers 31 and lower film layers 32 are hermetically connected to the upper and lower surfaces of the first liquid storage box 3 and the second liquid storage box 4 respectively. The upper film layer 31 and the lower film layer 32 are both aluminum films. The third cavity 23 is located below the first cavity 21 and the second cavity 22 and is respectively communicated with the first cavity 21 and the second cavity 22, a mixing box 5 is detachably installed in the third cavity 23, and the mixing box 5 provides a space for mixing different reagents in the first liquid storage box 3 and the second liquid storage box 4. A third film layer is sealed on the upper surface of the mixing box 5, a fourth film layer 52 is sealed on the lower surface of the mixing box 5, and the third film layer is attached to the lower film layer 32 of the first liquid storage box 3 and the second liquid storage box 4. The first liquid storage box 3, the second liquid storage box 4 and the mixing box 5 filled with different liquids can be selectively installed according to the different color developing liquids to be prepared.

[0022] Above the first cavity 21 and the second cavity 22, a connecting frame 6 connected to the loading platform 2 is installed. Two puncturing needles 7 respectively used for puncturing the first cavity 21 and the second cavity 22 are installed on the connecting frame 6. The puncturing needles 7 are used to puncture the upper film layer 31, the lower film layer 32 and the third film layer in sequence, so that the liquids in the first liquid storage box 3 and the second liquid storage box 4 flow into the mixing box 5 for mixing. The mixture is prepared as needed to avoid the color-developing solution becoming ineffective due to premature mixing.

[0023] Below the loading platform 2, a lifting platform 8 vertically slidably connected to the base 1 is installed.
