After heating is completed, the alcohol lamp is extinguished and the lamp cover is usually directly closed. However, the lamp cover cannot be directly placed due to the obstruction of the beaker or test tube above. At this time, the alcohol lamp needs to be taken out manually. When manually taking out the alcohol lamp, it is easy to burn the hands or cause other accidents. Utility Model Content

[0008] The solution is further that the positioning mechanism includes a T-shaped positioning rod fixedly installed on the side of the circular frame, the T-shaped positioning rod and the opposite surface of the circular frame are fixedly connected with a tension spring, the side of the circular frame is provided with a sliding hole, the surface of the T-shaped positioning rod overlaps the inner wall of the sliding hole, the side of the support plate is provided with a plurality of adjustment grooves compatible with the T-shaped positioning rod, the surface of the T-shaped positioning rod overlaps the inner wall of the adjustment groove, the side of the circular frame is provided with a threaded groove, and the surface of the connecting rod is threadedly connected to the inner wall of the threaded groove.

[0009] Technical effects and advantages of the utility model:

[0010] 1. The multifunctional reaction device for chemical experiments places the mounting block on the alcohol lamp in the groove. At this time, the arc surface of the T-shaped positioning block is forced to be accommodated in the T-shaped groove. After the mounting block is completely placed in the groove, the elastic force of the first spring pushes the T-shaped positioning block to be inserted into the positioning groove, so that the position of the alcohol lamp can be fixed, and then the alcohol lamp can be driven to move by pushing and pulling the sliding plate, so that there is no need to manually move the alcohol lamp from the heating position to avoid burns to the hands.

[0011] 2. The multifunctional reaction device for chemical experiments, when the sliding plate is moved, the arc surface of the T-shaped rod is forced to be accommodated in the T-shaped groove, and the second spring is squeezed. When the sliding plate is pushed back, the T-shaped rod moves to the countersunk hole, and the elastic force of the second spring pushes the T-shaped rod to be inserted into the countersunk hole, which can limit the sliding plate to prevent the sliding plate from moving when it is touched, thereby ensuring the stability of the position of the alcohol lamp when it is working.

[0012] 3. For the multifunctional reaction device for chemical experiments, pull the T-shaped positioning rod, the T-shaped positioning rod is pulled out from the adjustment groove, and the tension spring is stretched. Due to the lack of the limit of the T-shaped positioning rod, the circular frame can be moved at this time. Moving the circular frame can drive the fixture to move and adjust the height. Loosen the T-shaped positioning rod. Under the tension of the tension spring, the T-shaped positioning rod is inserted into the new adjustment groove to fix the height of the fixture for easy use.
