cutting tool

Abstract

The present invention provides a cutting tool, comprising: a shell; a motor accommodated in the shell and configured to drive a saw blade to rotate, the saw blade having a saw blade plane; and a bottom plate connected to the shell. The bottom plate comprises a first bottom plate having a first bottom surface and a second bottom plate having a second bottom surface. An abutment surface coplanar with the saw blade plane is provided on the second bottom plate. The first bottom plate is movably connected to the second bottom plate by means of a cam connection mechanism. The cam connection mechanism comprises a cam portion abutted against the second bottom plate. The cam portion is rotatably connected to the first bottom plate. The cam portion rotates to drive the second bottom plate to move with respect to the first bottom plate, to expose the abutment surface. Compared with the prior art, the cutting tool provided by the present invention prompts the second bottom plate to move with respect to the first bottom plate by abutting the second bottom plate against the cam portion, and is provided with a locking mechanism, so that when the second bottom plate moves to the second position, the abutment surface is maintained to be coplanar with the saw blade plane in the case of requiring the abutment surface to be matched with a guide device to realize a cutting operation.

Description

technical field [0001] The invention relates to a cutting tool. Background technique [0002] Cutting tools, such as electric circular saws, are commonly used power tools for cutting workpieces through saw blades. When cutting a workpiece, the usual way is to place the base plate of the cutting tool on the workpiece while aligning the saw blade with the cutting line marked on the workpiece, and then push the cutting tool on the surface of the workpiece to cut. However, during the cutting process, the operator often cannot guarantee the cutting accuracy due to human factors, and the work efficiency is relatively low. [0003] An existing solution is to use a guide device for guidance. When cutting, put the bottom plate of the cutting tool and a side parallel to the saw blade against the guide surface of the guide device, and then move the cutting tool to cut and ensure that This side of the bottom plate of the cutting tool always moves along the guide surface, which can avo...

Problems solved by technology

But this solution also has problems, because the base plate of the cutting tool has a certain width, and there is a certain distance between the saw blade and the side of the base plate, so people cannot directly align the guide surface of the guide with the cutting surface marked on the workpiece. Line alignment, but need to first measure the distance between the saw blade and the side of the bottom plate, and then fix the guide at the position where the distance between the guide surface and the cutting line is equal to the distance, which is cumbersome to operate, especially in When performing cutting that requires constantly changing the position of the guide device, the work efficiency is low; and because there may be certain errors in the measurement and setting the position of the guide device based on the measurement results, there may be some deviation between the actual cutting result of the cutting tool and the cutting line, Cutting accuracy is low
