AI Technical Summary
The shaking of the test tubes on the test tube rack is not conducive to the static solution. The existing test tube rack design causes the test tubes to shake, which affects the experimental results.
The design of the L-shaped block and the clamping plate is driven by the sliding sleeve and the spring to achieve the clamping and fixation of the test tube. The sliding sleeve squeezes the spring to drive the L-shaped block and the clamping plate to move and clamp the test tube.
Effectively fix the test tube to prevent shaking, ensure the solution is stationary, and avoid damage to the test tube when clamping.

Since the diameter of the circular hole on the test tube rack is larger than the diameter of the test tube, the test tube is easy to shake, which is not conducive to the static state of the solution in the test tube.
[0005] The utility model is realized through the following technical solutions:

[0010] Further, the test tube is placed in the placement hole and the placement groove.
[0011] Furthermore, the first sliding sleeve and the second sliding sleeve are both cylindrical structures.
[0012] The utility model has the following beneficial effects:
[0013] 1. The utility model compresses the spring by pulling the first sliding sleeve and the second sliding sleeve, drives the first L-shaped block and the first clamping plate to move by the first sliding sleeve, and drives the second L-shaped block and the second clamping plate to move by the second sliding sleeve, so that the test tube can be placed between the first clamping plate and the second clamping plate, and then the first clamping plate and the second clamping plate are clamped and fixed to the test tube by the action of the spring. Since the diameter of the circular hole on the test tube rack is larger than the diameter of the test tube, the test tube is easy to shake, which is not conducive to the static state of the solution in the test tube.
