The indicator light 13 is on, and the indicator light 13, the fixed electrode plate 12 and the movable electrode plate 11 are electrically connected; when the test tube after use is to be stored, the slide bar 15 is pressed downward to move it downward along the slide groove 14, and then the push block 17 is also moved downward, so that the two movable plates 7 can be pushed away from each other, and then the two arc-shaped clamping plates 6 are also moved away from each other. At this time, the second spring 5 is compressed and the test tube is placed on the lifting circular plate 9. Due to the gravity of the test tube, the lifting rod is pressed to move vertically downward, and the first spring 10 is compressed, thereby driving the movable electrode plate 11 to move vertically downward until it contacts with the fixed electrode plate 12, the indicator light 13 is powered on and becomes bright, and the hand is withdrawn from the slide bar 15 at the same time. Due to the resilience of the second spring 5, the two arc-shaped clamping plates 6 are close to each other, so that test tubes of different sizes can be clamped and fixed.

[0021] See also Figure 3-5As shown, each placement plate 3 is provided with two rectangular grooves 4, and the two rectangular grooves 4 are located on both sides of the sleeve 8, and a movable block is slidably installed in each rectangular groove 4, and a second spring 5 is fixedly connected between each movable block and the inner wall of the end of the rectangular groove 4 away from the sleeve 8, and the second spring 5 is arranged in the rectangular groove 4, and an arc-shaped clamping plate 6 is fixed on the top of each movable block, and the two arc-shaped clamping plates 6 on the same placement plate 3 are symmetrically arranged, and a connecting rod is fixedly connected to each arc-shaped clamping plate 6, and a movable plate 7 is fixed to each connecting rod; when clamping and fixing the test tube, the second spring 5 and the arc-shaped clamping plate 6 cooperate with each other, so that test tubes of different sizes can be clamped and fixed, thereby improving the applicability of the device.

[0022] Working principle: Since the existing glass instrument storage device cannot store glass test tubes of different sizes and models, the applicability of the device is reduced, and the glass test tubes cannot be effectively clamped and fixed, which easily causes the glass test tubes to tilt and collide with each other, which is easy to cause damage and is not conducive to the storage of glass test tubes; therefore, in view of the above problems, a glass instrument storage device for analytical chemistry experiments is proposed; when storing the test tubes after use, the slide bar 15 is pressed downward to move it downward along the slide groove 14, and then the push block 17 is also moved downward, so that the two movable plates 7 can be pushed away from each other, so that the two arc clamps The holding plates 6 also move away from each other. At this time, the second spring 5 is compressed, and the test tube is placed on the lifting circular plate 9. Due to the gravity of the test tube, the lifting rod is pressed to move vertically downward, and the first spring 10 is compressed, thereby driving the movable electrode plate 11 to move vertically downward until it contacts the fixed electrode plate 12. The indicator light 13 is powered on and becomes brighter. At the same time, the hand withdraws from the slide bar 15. Due to the rebound force of the second spring 5, the two arc-shaped clamping plates 6 are brought close to each other, so that test tubes of different sizes can be clamped and fixed.
