TECHNICAL FIELD
The present disclosure relates to a gauge plate which is configured to drill at least one accommodation hole to accommodate a square drill tool (such as a square reamer).
BACKGROUND
An operation panel of a conventional distribution box contains at least one square meter fixed thereon, wherein at least one square accommodation hole is drilled on the operational panel. Referring to FIG. 13, before drilling the at least one square accommodation hole, a central orifice is marked at a predetermined position of a workpiece, and a size (such as 91 mm×91 mm) of each of the at least one accommodation hole is drawn. In addition, a worker has to plan a central point 71 of a drilled position of each accommodation hole, and the size a, b of each accommodation hole is planned by using a ruler, thereafter the size of each accommodation hole is cut.
However, such a drilling process is troublesome and time-consuming and will spend a high mold cost.

The gauge plate further contains multiple V-shaped notches defined on the four peripheral sides of the gauge plate and corresponding to the four alignment orifices and the four T-shaped slots so that the gauge plate is aligned with the four alignment orifices and the four T-shaped slots by using the multiple V-shaped notches, and a size value portion is configured to display three size values.
In operation, the four L-shaped slots of the gauge plate are aligned with a criss-cross dotted line of a central point of spaced from a first distance and a second distance of the workpiece, and a peripheral side of the at least one accommodation hole is cut by using the four L-shaped slots, thus drilling the at least one accommodation hole easily and quickly.
Preferably, the gauge plate comprises a ruler scale formed on a first peripheral side of the four peripheral sides of the gauge plate and configured to measure a size and to draw a line.
Preferably, the gauge plate contains two L-shaped ribs extending from two corners of the four corners of the gauge plate away from the level and configured to raise up the gauge plate.
Preferably, the gauge plate further contains a level arranged on a center of the second peripheral side thereof and configured to make a level correction.
Preferably, the gauge plate contains multiple magnetic attraction elements extending adjacent to the four corners of the gauge plate, made of metal and configured to magnetically attach the gauge plate on a metal element.
Preferably, the gauge plate is made of magnetic metal material so as to magnetically attach on the metal element.
Other objects and features will be in part apparent and in part pointed out hereinafter.
