Description

Lifting iron stand Technical Field The utility model relates to the technical field of experimental instruments, in particular to a lifting iron stand. Background The chemical experiment is a series of operations for researching chemical phenomena by observing, measuring and analyzing chemical reactions and substance properties, the iron stand for experiment is a tool for supporting a test tool to be used by a person for experiment, and the iron stand can stably support various experimental equipment, such as a flask, a test tube, a buret and the like, so that the safety and accuracy of an experimental process are ensured. An experimental iron stand is disclosed in patent document CN211586689U, which is searched. Comprises a base, a supporting column vertically fixed on the base, a flask clamp and an iron ring which are assembled on the supporting column; the four corners of the bottom of the base are respectively provided with a base fixing device for fixing the base on the operation table surface, and the base fixing device comprises a supporting seat fixedly assembled on the base, a fixed sucker assembled at the bottom of the supporting seat and a sucker pull rod for operating the fixed sucker. According to the utility model, the base fixing devices are respectively assembled at the four corners of the bottom of the iron stand base, so that the iron stand base and the operation table surface are adsorbed and fixed, the problem of damage to an experimental instrument caused by the toppling of the iron stand due to accidental collision or iron stand load in the experimental teaching process is effectively solved, and the safety of experimental teaching is ensured. With respect to the related art in the above, the inventors consider that there are the following drawbacks: 1.
