Technical Field

[0001] The utility model relates to the technical field of rocker arm equipment, in particular to an integrated hoisting rocker arm device. Background Art

[0002] At present, the process of campus physics and chemistry experiments often requires experimental actions including clamping, adjusting and rotating. The completion of such actions requires the assistance of a variety of auxiliary tools, which is easy to cause interference and has a poor memory effect on students in demonstration teaching.

[0003] Taking chemical experiments as an example, some experimental vessels need to be clamped by fixtures and need to be kept in a hoisted state after being adjusted to a predetermined experimental position, such as the heating height. In the subsequent experimental process, there are many situations such as moving the experimental vessels away to observe experimental phenomena or add experimental reagents, and then resetting them. Therefore, it is necessary to consider how to simplify auxiliary tools as much as possible and realize functional integration to meet the routine experimental actions of clamping, adjusting and rotating, so as to facilitate more effective demonstration and teaching. In view of this, we propose an integrated hoisting rocker arm device. Utility Model Content
