Inspired by: I am an innovative engineer/designer. While I was repairing home appliances, I found it rather difficult / uncomfortable to loosen/fasten a bolt joint in the limited space with tradition way using two separated wrenches, and have to use two hands at the same time. I thought that a lot of people would have same experiences as I had. They all deserve a better tool to do this type of tasks. So, I spent a lot of time coming up this design, so that one can pre-setup the device, operate safely with only one hand. I hope this tool could benefit millions of workers.
