Description

Technical Field

[0001] This utility model relates to the technical field of laser tube cutting machines, and in particular to a lifting device. Background Technology

[0002] The material support device of a laser tube cutting machine is an important component. Its main function is to support and transport the raw material tube while ensuring stability during the cutting process.

In use, when connecting the output end of the cylinder to the support arm, the connecting frame of the cylinder output end is directly moved to the inner walls on both sides to fit against the two ends of the connecting rod, and then the pushing component drives the locking block to move into the locking hole, and the locking block connects the connecting frame and the connecting rod, thereby connecting the output end of the cylinder to the support arm through the connecting frame and the connecting rod.
