Description
Technical Field
[0001] The utility model relates to the technical field of stage lights, in particular to a drag chain structure of a cutter. Background Art
[0002] At present, most cutters in the prior art are designed to perform a reciprocating motion of rotating 120 degrees along a track, that is, including a base and a cutting unit.

At the same time, the first connector 400 is fixedly connected to the cutting unit 200, and the second connector 500 is fixedly connected to the base 100. Thus, when the cutting unit 200 is running, the drag chain structure can follow the movement track of the cutting unit 200, reducing the occurrence of wire winding and cable friction and skinning, and further improving the safety of the cutter.
