Abstract

The present invention discloses an electric circular saw. It includes machine body, baseplate and guide device mounted on said machine body. Said guide device includes roller and supporting mechanism connected with roller and baseplate, said supporting mechanism includes at least an elastic element. When the roller is pressed, the elastic deformation of said elastic element can make the central shaft of roller be moved relatively to said baseplate.

Description

technical field [0001] The invention relates to an electric circular saw, in particular to an electric circular saw with a guide device on the bottom plate. Background technique [0002] In the process of using an electric circular saw to process a workpiece, the bottom plate of the electric circular saw is usually placed on the workpiece, and the operator pushes the electric circular saw forward to cut the workpiece. Since the sliding friction between the bottom surface of the bottom plate and the workpiece must be overcome during use Work makes the operator extremely fatigued, and often causes the cutting to deviate from the direction due to operational errors. U.S. Patent No. 5,056,499 discloses a guide device on a cutting machine for cutting cement. It achieves the purpose of guiding by installing rollers on the bottom plate, but because the rollers are all located on the same side of the saw blade, the cutting machine is easy to turn over The bottom surface of the bot...
