Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a clamp used for experimental instruments and a laboratory table comprising the clamp. Background Art

[0002] In chemical experiments, various experimental instruments such as utensils, test tubes, stirring devices, etc. are often needed. These experimental instruments usually need to be fixed on a special experimental instrument placement rack, and then the placement rack is placed on the table of a laboratory table or laboratory cabinet to facilitate experimental operations.

[0003] However, the commonly used method for fixing the laboratory instrument rack currently relies mainly on the hand-tightening nut device. This fixing method is prone to loosening of the hand-tightening nut after long-term use, which makes the fixation of the laboratory instrument insufficient, increases the safety hazard in the experimental operation, and may even lead to the occurrence of experimental accidents. In addition, due to the material and structural characteristics of some laboratory instruments, they cannot be clamped too tightly, otherwise their surface may be damaged, thereby affecting the accuracy of subsequent experimental results; for example, the surface of glass test tubes and precision instruments may produce fine cracks or deformation due to excessive clamping, and may even directly damage the instrument.

[0004] Therefore, there is an urgent need for a clamp that can ensure that the experimental instrument is firmly fixed and avoid damage to the instrument caused by excessive clamping. Utility Model Content
