Description

Round cutting die frame of woodworking edge trimmer Technical Field The utility model relates to the technical field of woodworking operation, in particular to a round cutting die frame of a woodworking edge trimmer. Background In woodworking, when the edge of a wood board is required to be decorated or the surface of a workpiece is required to be planed, a woodworking edge trimmer is usually used for trimming and planed, and although the woodworking edge trimmer can usually finish the processing of general trimming or straight line cutting, when the circular or arc cutting processing is required to be performed on the workpiece, the existing woodworking edge trimmer does not provide an accessory capable of limiting the circular or arc processing movement path, so that the woodworking edge trimmer can accurately cut the workpiece along the preset circular or arc path, therefore, most of the existing constructors draw the circular or arc path to be processed on the workpiece before the workpiece, and then cut the workpiece in a handheld mode, and therefore, after the final finishing, the processed circular or arc groove of the workpiece is not easy to accurately obtain a flat processing surface, and therefore, the practicability is low. Disclosure of utility model The utility model aims to overcome the existing defects, and provides a circular cutting die frame of a woodworking edge trimmer, wherein a positioning plate is nailed into a wood board to be processed through one of matched positioning holes and steel nails, then a first handle is rotated to drive a stud to rotate, the stud rotates to drive a third arc plate to move upwards under the action of a limiting block and a limiting groove, the third arc plate moves upwards so that an optical axis is not abutted tightly, the optical axis can move in the left-right direction to adjust the diameter of a cut circle, when the optical axis is adjusted to the required size, the first handle works reversely to enable the third arc plate to move downwards to abut against the optical axis so as to avoid shaking of the optical axis in the processing process, and when the optical axis moves in the left-right direction, the optical axis is prevented from moving transversely under the action of a compression spring and a second arc plate, so that the practicality and the use effect of the circular cutting die frame of the woodworking edge trimmer are improved, in addition, scale marks are arranged on the optical axis, and the value of the scale marks along the line groove is the size of the cut circle, so that the problem in the background technology can be effectively solved.
