When the electric telescopic rod 2 is working, it is used to drive the condenser 5 and evaporating flask 4 on the rotating head 3 to move up and down, so that the evaporating flask 4 can be inserted into the heating pot 102 for heating.

[0042] By tightening the first threaded shaft 604 and the second threaded shaft 605, it is convenient to lock and fix the second adjusting rod 602 and the rotating rod 601, thereby auxiliary fixing the condenser 5 on the fixing sleeve 603, providing auxiliary support function when fixing the condenser 5 on the rotating head 3.

[0043] It also includes a control box 101, which is arranged on the side of the bottom box 1. The control box 101 is provided with a display screen. The control box 101 is used to control the operation of the motor, the electric telescopic rod 2, the vacuum pump, etc.
