[0002] A beaker gripper, also known as a beaker clip or beaker tongs, is one of the commonly used tools in a laboratory, mainly used for gripping, moving and handling containers such as beakers and test tubes. Especially when these containers are filled with high-temperature or corrosive liquids, the publication number CN203750572U discloses a test tube and beaker dual-purpose clip, belonging to the technical field of experimental equipment. It includes a test tube clip arm, a beaker clip arm and a connecting bolt. The outer side of the test tube clip arm is a straight arm, and there are multiple symmetric semi-circular grooves on the inner side; one end of the test tube clip arm is connected to the beaker clip arm to form half a clip, and the shape of the beaker clip arm is a semi-circular ring; the beaker clip arm of the half clip is hinged through a connecting bolt to form a clip. It realizes the full utilization of test tube clip resources. The sizes of the three test tube clip openings are different, and it can play the effect of multi-purpose use, and is used for gripping test tubes of different models. Although this product is convenient for gripping different test tubes and beakers, it is not convenient to extend the gripping position. When a certain safety distance needs to be maintained for some special experiments, there will be certain risks with ordinary gripping devices, increasing the danger of the experiment, and the practicability is poor and needs to be improved.
