The utility model discloses a rosemary steaming tray taking and placing tool relates to rosemary processing field, including main rod, magnetic attraction part and N support rod, the bottom end welding fixed of main rod has the conical head, and its inside is hollow setting, the support rod is the iron bar spare, N the support rod around setting in the outside of main rod, and the bottom end of support rod is articulated with the top of conical head, the magnetic attraction part sets up in the inner chamber of main rod for adsorbing N support rod, makes support rod vertical and fits the outer wall of main rod, the utility model discloses through the conical head through rosemary and the central hole of steaming tray, after pulling up L type pull rod and rotating fixedness, the magnetic bar removes the adsorption of support rod, makes four support rods spread, and evenly supports the bottom of steaming tray, ensures that the taking and placing process is stable and reliable, avoids the steaming tray inclination or slippage, and this tool operation is simple, and convenient to use, avoids scalding simultaneously, and improves operating efficiency.

The utility model discloses a nitrogen distillation instrument capable of being fixed quickly, which comprises a distillation instrument body, the distillation instrument body comprises a shell, a heating mechanism arranged on the shell, a flask fixing mechanism and a condenser pipe fixing mechanism, the flask fixing mechanism and the condenser pipe fixing mechanism are arranged on the shell, the flask fixing mechanism is positioned above the heating mechanism, and the condenser pipe fixing mechanism is positioned above the shell. The flask fixing mechanism comprises a positioning plate, a first screw rod rotationally arranged on the positioning plate and first clamping blocks rotationally connected with the first screw rod, one end of each first clamping block is fixedly connected with the shell, each first clamping block is correspondingly provided with a second clamping block, and the second clamping blocks are fixedly connected with the shell. The tail end of the second clamping block and the tail end of the first clamping block are each provided with an arc-shaped clamping piece so that a flask can be fixed through the two clamping pieces. By arranging the first clamping block, the second clamping block and the first lead screw, the distance between the first clamping block and the second clamping block is adjusted, and the flask is clamped through the two arc-shaped clamping pieces so that the flask can be rapidly fixed.
