For the traditional electric saw is only a vertical or horizontal one-way tool, Turning was made as an upgraded version of the traditional one. With a changeable transmission shaft structure and two using directions, Turning provides more feasibility for use in many scenarios under the premise of the driving force can be used normally.
Furthermore, we investigated the existing tools in the market and set two themes for use: sawing and grinding. Basing on the theory of ergonomics, we have changed the structure and style of the grip, and adopted the oval grip with a turning point to enhance the user's using feelings.
Problems and solutions
When the carpenters use electric saws, their bodies need to change the position continuously or change the position of the boards during the work. We carried out the research on the electric circular saw in view of the situation that sometimes their use will lead to the distortion of the saw groove, and it is inconvenient for them to use the saws when grinding the wood.
In terms of different working methods and use scenarios,we add a second direction to the circular saw so that users can choose the most suitable direction for work with ease. In addition, we have designed a more suitable handshape of the grip for use.
On the basis of using the basic gear transmission as the power transmission, the traditional single guide gear transmission has been changed into variable two-way transmission according to the torque.
