Description

Technical Field

[0001] This utility model relates to the field of electric circular saw technology, and in particular to an electric circular saw with laser aiming function. Background Technology

[0002] An electric circular saw is a tool that uses a single-phase series-wound electric motor to drive a circular saw blade through a transmission assembly for sawing operations. It features safety, reliability, a reasonable structure, and high work efficiency, and is suitable for sawing wood, fiberboard, plastics, flexible cables, and similar materials. Currently, operating an electric circular saw requires the operator to coordinate hand and eye movements, observing the difference between the saw blade position and the cutting line, and making timely fine adjustments, or directly observing the already cut trajectory and adjusting according to the magnitude of the deviation, thus achieving line-aligned cutting. However, adjusting by observing the saw blade position or the already cut trajectory has a large margin of error and requires a high level of skill from the operator. Novices often struggle to get close enough to the cutting line and tend to leave too much safety distance, leading to material waste. Even skilled operators sometimes make mistakes.

[0003] Publication number CN214815349U discloses an electric circular saw with a laser line marker, comprising an electric circular saw, a base plate connected to the bottom of the electric circular saw via a rotating structure, an angle fixing plate that mates with the electric circular saw on the top of the base plate, and an infrared laser head fixed to one end of the electric circular saw via a rotating structure. While this technical solution can achieve laser line marking on the electric circular saw, the connection structure between the laser head and the main body of the electric circular saw is relatively complex, making the assembly of the electric circular saw with the laser head quite complicated. Therefore, an electric circular saw with laser aiming function is provided to solve the above problems. Utility Model Content
