[0002] It is common operation in chemical field to use water bath kettle and iron stand to build heating reflux device to extract and distill. The iron stand is generally assembled by base, fixed clamp and flask clamp. Before heating reflux operation, the iron stand is assembled first, then water bath kettle and iron stand are moved to adjust the layout, then the length of fixed clamp is adjusted one by one to match the position of condenser tube and flask. Then flask and condenser tube are placed, the length of fixed clamp is determined, and finally the tightness of fixed clamp is adjusted one by one to fix condenser tube and flask. When 6-hole water bath kettle is used to distill simultaneously, at least 6 iron stands and 12 flask clamps are used to fix.

[0003] The whole operation process is time-consuming and complicated. Moreover, when using iron stand, more space is occupied, and large space is also needed for daily storage of iron stand. Each time, clamp is repeatedly screwed, and iron stand is prone to rust, which is difficult to screw after rusting and has short service life. Sometimes, the clamp is not tightly clamped, which is prone to looseness, so that the device is unstable and is likely to be tilted. When tilted, the vessel is prone to breakage, which can cause glass cut of personnel and even chemical reagent contact hazard. UTILITY MODEL CONTENT
