[0004] However, when the above device is in use, although one end of the carbon fiber is fixed by the fixing device, the other end is only limited by the wire hole and is not fixed. This causes the carbon fiber to be in a loose state when the cutting blade is cutting, which reduces the cutting accuracy of the device.

[0005] To address this issue, we propose a linear density sampling device for carbon fiber testing. Utility Model Content
