The 7th power tool design competition,

Since the traditional chainsaw is only a vertical or horizontal one-way tool, we have manufactured an upgraded version of the traditional chainsaw-Turning. Under the premise that the driving force can be used normally, the transmission shaft structure of this product is changeable, with two directions of use, and it is more feasible to use in a variety of scenarios. In addition, we investigated the existing tools on the market and set two themes for use: sawing and grinding.
Based on the principle of ergonomics, we changed the structure and style of the grip, and adopted the oval grip with inflection point to enhance the user's experience. When carpenters use chainsaws, according to different needs, the body needs to constantly change positions or change positions of boards. In view of the fact that sometimes its use method will cause the saw groove to be twisted, and it will also encounter inconvenient use when polishing the wood board, we have launched a research on the electric circular saw. For different working methods and usage scenarios, we have added a second direction to the circular saw, so that users can easily choose the most suitable working direction.
In addition, we also designed a grip that is more suitable for hand shape for use. On the basis of using the basic gear transmission for power transmission, the traditional single-guided gear transmission is changed according to the torque and becomes a changeable two-way transmission.

The idea is great! But I didn't understand how to realize the structure of the transformation of the two modes.
