[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that: specifically, the support assembly 9 includes a support seat 91, a gear rod 92, a support plate 93, a clamping rod 94, a clamping slide block 95 and a clamping spring 96, wherein the support seat 91 is arranged at one end above the base 1, a gear rod 92 is arranged inside the support seat 91, a support plate 93 is arranged on one side of the gear rod 92, a clamping rod 94 is arranged on the other side of the gear rod 92, a clamping slide block 95 is arranged above the clamping rod 94, and a clamping spring 96 is arranged on one side of the clamping slide block 95.

[0033] By adopting the above technical solution, the clamping rod 94 is pulled, and the clamping rod 94 drives the clamping slider 95 to move and compress the clamping spring 96, so that the clamping rod 94 disengages from the gear rod 92, and then the support plate 93 automatically moves down and disengages from the collecting bottle 4, and then the collecting bottle 4 can be removed from the bottom of the condenser 8. During installation, the collecting bottle 4 is inserted under the condenser 8, and then the gear rod 92 is directly pulled to drive the support plate 93 to move up, so as to support and fix the collecting bottle 4, so that the device can be conveniently disassembled and assembled for the collecting bottle 4 when in use, thereby improving the convenience of use.

[0037] The structure and use principle of the heating box 2, lifting assembly 3, connector 5 and condenser 8 in the utility model have been disclosed in a flask fixing device for a rotary evaporator disclosed in Chinese patent application No. 202120239826.9, and its working principle is that when the liquid material needs to be distilled, the liquid material to be distilled is added to the inside of the flask 7, the flask 7 is fixed, and the motor is running at the same time. When the motor is running, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the threaded tube to move, and also drives the flask 7 to move. When the bottom of the flask 7 enters the interior of the heating box 2, the motor stops running, and the heating box 2 is running at the same time, and the liquid material can be distilled.

[0038] Working principle and use process of the utility model: In the utility model, when it is necessary to distill the liquid material, the liquid material to be distilled is added to the interior of the flask 7, the flask 7 is fixed by the convenient fixing component 6, and then the collecting bottle 4 is installed and fixed by the supporting component 9, and then the flask 7 is placed in the heating box 2 for distillation by the lifting component 3. When the convenient fixing component 6 is in use, one end of the flask 7 is inserted into the connecting seat 61, and then the turning handle 63 is rotated. The turning handle 63 rotates to drive the bidirectional trapezoidal screw rod 62 to rotate, and the bidirectional trapezoidal screw rod 62 rotates to drive the square slider 64 to move. The square slider 64 moves to drive the connecting block 65 to move, and the connecting block 65 moves to drive the clamping seat 66 to clamp and fix the flask 7. When the clamping seat 66 is clamped, the clamping plate 661 moves in the clamping seat 66. Compress the fastening spring 662 until the fastening spring 662 is compressed to the point where the flask 7 can be clamped, so that the device can clamp in a good manner, and the clamping effect is good, and the clamping force can be buffered, so that the device can be conveniently installed and fixed to the flask 7 when in use, and the convenience is high. When the support assembly 9 is in use, the clamping rod 94 is pulled, and the clamping rod 94 drives the clamping slider 95 to move the compressed clamping spring 96, so that the clamping rod 94 is disengaged from the gear rod 92, and then the support plate 93 automatically moves down and disengages from the collecting bottle 4, and then the collecting bottle 4 can be removed from the bottom of the condenser 8. During installation, the collecting bottle 4 is plugged under the condenser 8, and then the gear rod 92 is directly pulled to drive the support plate 93 to move up, support and fix the collecting bottle 4, so that the device can be conveniently disassembled and assembled to the collecting bottle 4 when in use, thereby improving the convenience of use.
