[0003] In CNC sawing machines, the workpiece is clamped and fixed by a clamping device before being sawn by the sawing structure. However, existing clamping devices are fixed structures. The workpiece is released or clamped by moving the clamping device. But if the workpiece is cylindrical, and its diameter is large, with a radius greater than the height of the clamping device, the device cannot clamp it securely and properly because it is lower than the radius of the workpiece. This makes it unsuitable for workpieces of various diameters and heights, limiting its flexibility. Therefore, the clamping height of the clamping device in a sawing machine should be more flexible, capable of accommodating workpieces of different heights and diameters. Utility Model Content
