[0001] The present invention relates to a processing workbench used when processing electrical equipment materials using power tools. [Background technology]

[0002] At construction sites such as buildings and factories, when processing electrical equipment materials to be used in electrical equipment, power tools are used to perform the necessary processing for installation.

[0003] For example, if the electrical equipment material is a box, an electric drill is used as a power tool to drill the holes necessary to install the box. If the electrical equipment material is a pipe, a rotary band saw is used as a power tool to cut the pipe to the length of the installation location. Furthermore, if the electrical equipment material is a steel plate, a jigsaw (jigsaw) is used as a power tool to cut the steel plate into the desired shape. During this processing work, the worker places the electrical equipment material on the floor or elsewhere and holds it in place with their feet or hands while processing.

[0004] Here, as a means for fixing electrical equipment materials during machining work, there is a fixing clamp that fixes a plate-like panel to be machined to a machining workbench (see, for example, Patent Document 1). This fixing clamp has at least one support body, a frame whose position can be adjusted relative to the support body in the direction of clamping / unclamping, and at least two clamping and fixing tips that are driven into one of the side edges of the panel, so that the plate-like panel can be firmly fixed to the workbench of the machine tool and can be clamped / unclamped.
