[0002] Engineering plastics refer to high-performance polymer materials that can be used as structural materials, withstand mechanical stress within a wide temperature range, and are used in harsh chemical and physical environments. Engineering plastics have excellent comprehensive properties, such as high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can replace metals as engineering structural materials, but are more expensive and have smaller production volumes.

In actual use, although the existing multi-path cutting device can achieve basic cutting functions, the existing multi-path cutting device generally does not have the function of automatically clamping and fixing the engineering plastics. It is necessary to rely on manual use of clamps to fix the engineering plastics. This fixing method not only increases the workload of the operator, but also has low efficiency in fixing engineering plastics. Therefore, it needs to be improved. Utility Model Content
