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

[0003] When supporting materials, the traditional support method is to use a cylinder to drive the support arm to rotate and move the lifting roller at one end of the support arm to the required height. After use, the support arm is reset by the cylinder. During use, the support arm and the output end of the cylinder are connected by a hinge. During the use of the cylinder, the piston, sealing ring and other parts may wear due to friction, so regular inspection and replacement of worn parts can prevent failures. When maintaining the cylinder, tools are needed to disassemble the hinge between the output end of the cylinder and the support arm, which increases the difficulty of the work. Utility Model Content

When the clamping block 705 moves, the guide block 702 slides inside the guide groove 703. When the guide block 702 moves to fit the inner wall of one side of the guide groove 703, the guide groove 703 will limit the guide block 702 so that it cannot continue to move, thereby limiting the moving distance of the clamping block 705 by limiting the moving distance of the guide block 702.

[0034] Specifically, the lifting member includes a fixing base 4 fixedly connected to one end of the support arm 3 , and a roller 5 is provided on the top of the fixing base 4 .
