Description

Technical Field

[0001] This utility model belongs to the field of cutting device technology, and specifically relates to a cutting device that facilitates improved cutting accuracy. Background Technology

[0002] In production, different workpieces (such as foam boards) are cut and trimmed to complete specific cutting operations for convenient subsequent use. However, during the cutting operation using a cutting device, if the workpiece is not completely fixed, the external force generated by the cutting blades during cutting can cause the workpiece to deviate. This prevents the workpiece from completing the cutting operation along the predetermined path, resulting in numerical deviations after cutting, poor cutting accuracy, or even unusable workpieces due to excessive deviations. This necessitates repeated cutting, affecting the normal progress of the cutting operation. There are also workpieces that cannot be trimmed and must be scrapped, increasing the waste of raw materials.

[0003] In summary, the cutting device that does not completely fix the workpiece has some problems in use, so it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
