The first position of the cutter blade 41, after the workpiece is mounted on the cutting device, is a position where the cutter blade 41 is spaced apart from the workpiece. For example, the cutter 41 is positioned above the workpiece in fig. 3. The second position of the cutter 41 refers to a position at which the cutter 41 moves toward the workpiece and cuts the workpiece.

As shown in fig. 1, in some embodiments, the workpiece fixture 32 includes opposing first and

second ends

321, 322. The first end 321 is pivotally connected to the workpiece holder 3, and the second end 322 is configured to rotate relative to the workpiece holder 3 with the pivotal connection point of the first end 321 and the workpiece holder 3 as a rotation center, and further to open and close at one side of the workpiece limiting groove 31.
