Preferably, the lower end surface of the adjusting block is provided with a magnet sheet, which can make the support of the adjusting block by the secondary tightening nut more stable.

Preferably, the diameter of the through hole is larger than the diameter of the screw, which is convenient for the adjustment block to move up and down quickly.

Preferably, the support legs are provided with pegs, and the pegs are provided with a windshield, which can reduce the influence of wind on the flame of the alcohol lamp.

Preferably, the windshield is provided with hanging holes, and the number of the windshield is 2-3.

The beneficial effects of the present utility model are:

The utility model has a simple structure, can quickly adjust the height, and has the function of preventing wind, and at the same time, the utility model can also be used as a fixed tripod.
