Problems solved by technology
Electric circular saws are usually equipped with multiple saw blades. The difference between these saw blades is that the saw teeth on them are different in density. The thin saw teeth have high cutting efficiency, but the cut surface is rough, and the dense saw teeth have low cutting efficiency but the cut flat surface
Therefore, when cutting, the operator often chooses the most suitable saw blade according to the situation, but it is inconvenient to carry these saw blades at any time.

The invention discloses an electric circular saw with indicating lines comprising a saw body and a saw blade and a rotating block; the rotating block is embedded in the saw blade in a rotary mode, and the rotating block is fixed with the saw blade through a clamping bolt after rotating; the saw blade is provided with a cavity which comprises a plurality of blades therein; the blades are uniformly arranged in a circumference mode; one ends of the blades are hinged to the rotating block; the other ends of the blades extend from the saw blade; each blade is provided with a waist hole; the cavity is provided with limiting posts whose number is identical to that of the blades; the limiting posts are positioned inside the waist holes; the rotating block is provided with three indicating lines and one indicator, wherein the indicator rotates along with the rotation of the rotating block, and each indicating line represents the density of the blades. Operators can adjust the density of sawtooth without changing the saw blade, which is quite convenient.
Description
technical field [0001] The invention belongs to the field of electric tools, in particular to an electric circular saw with indicator lines. Background technique [0002] The electric circular saw is a tool that uses a single-phase series-excited motor as the power to drive the circular saw blade through the transmission mechanism for sawing operations. It has the characteristics of safety, reliability, reasonable structure, and high work efficiency. Suitable for sawing wood, fibreboard, plastic and flexible cables and similar materials. Electric circular saws are usually equipped with multiple saw blades. The difference between these saw blades is that the saw teeth on them are different in density. The thin saw teeth have high cutting efficiency, but the cut surface is rough, and the dense saw teeth have low cutting efficiency but the cut flat surface. Therefore, when cutting, the operator often selects the most suitable saw blade according to the situation, but it is in...
