[0002] In chemical laboratories, researchers often need to fix test tubes in specific positions to carry out operations such as reactions, mixing and heating. The test tube clamping adjustment mechanism can ensure that the test tubes are firmly fixed in place for various chemical experiments.

[0003] An existing test tube clamping and adjusting mechanism has the following disadvantages: when experimenters conduct experiments on test tubes, most of them use buckles to clamp the test tubes, and the buckles are not easy to adapt to test tubes of different diameters, which causes experimenters to frequently replace the buckles, affecting the experimenters' experimental efficiency. Utility Model Content

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a test tube clamping and adjusting mechanism, comprising an outer cylinder, a sliding cylinder is slidably connected to the inside of the outer cylinder, a positioning plate is fixedly connected to the bottom of the sliding cylinder, an electric telescopic rod is fixedly connected to the bottom of the positioning plate, a positioning assembly is fixedly connected to one side of the electric telescopic rod, a bracket is fixedly connected to one side of the inner wall of the sliding cylinder, and a screw is connected to the middle of the top surface of the bracket by rotation.

[0006] Optionally, the positioning assembly includes a spring whose one end is fixedly connected to one side of the surface of the electric telescopic rod, and the other end of the spring is fixedly connected to an arc-shaped stopper.

[0007] Optionally, a shock-absorbing piston rod is sleeved inside the spring, and the number of the springs is three.

[0008] Optionally, a connecting rod is fixedly connected to one side of the outer cylinder, and a fixing block is fixedly connected to one end of the connecting rod.

[0009] Optionally, a mounting plate is fixedly connected to one side of the fixing block, and a surface of the mounting plate is provided with mounting bolts penetrating through a circular array of equidistant threads.

[0010] Optionally, a connecting bolt is threadedly connected to the middle of the surface of the mounting plate, and one end of the connecting bolt is fixedly connected to a suction cup.

[0011] The utility model provides a test tube pressing and adjusting mechanism, which has the following beneficial effects:

[0012] 1. The test tube pressing and adjusting mechanism, through the arrangement of the outer tube, the sliding tube and the screw, when the staff needs to press the test tube, the test tube can be inserted into the bottom of the sliding tube in advance, and then the staff twists the screw to drive the sliding tube to move downward, so that the sliding tube presses the test tube, thereby facilitating the staff's operation and reducing the cumbersomeness of the operation steps.

[0013] 2. The test tube clamping and adjusting mechanism is provided with an electric telescopic rod and a positioning assembly. When the staff compresses the test tube, the staff can turn on the power of the electric telescopic rod.
