Description

Technical Field

[0001] The utility model belongs to the technical field of laser tube cutting machines, and in particular relates to a rear chuck for clamping tubes used in laser tube cutting machines. Background Art

[0058] A second tooth block 702 is meshed with the surface of another set of the second transmission gears 701 , and a second clamping block 703 is fixedly mounted on one side of the second tooth block 702 .

[0059] When the second rack 604 moves with the movement of the second connecting block 603, it can drive one of the groups of second transmission gears 701 meshing on its surface to rotate.
