[0018] The utility model hand-held test tube clamp is used as follows:

[0019] When it is necessary to clamp the test tube, hold the handle 1 with your hand so that the main clamping arm 2 fixed to the handle 1 is close to the instrument, and push the pushing rod 3 forward with your thumb. The pushing rod 3 drives the wedge-shaped slider 5 to move in the direction of the instrument, so that the roller 7 slides in the opposite direction to the wedge-shaped slider 5. The movement of the roller 7 drives the auxiliary clamping arm 9 to rotate, so that the first clamping ring 10 and the second clamping ring 11 are separated, and the clamping action is realized. The test tube is placed between the separated first clamping ring 10 and the second clamping ring 11, and the pushing rod 3 is released. The pushing rod 3 drives the wedge-shaped slider 5 to move toward the handle 1 under the action of the reset spring 4.
