A DUAL FASTENER MANIPULATION DEVICE can be used to manipulate two fasteners with the same axis of rotation and to manipulate the fasteners of the same axis of rotation separated by the intermediate material, and the spacing distance can be freely adjusted according to the size of the separated object.

In order to successfully join the two fasteners together, one of the fasteners must be rotated in the first direction and the other fastener must be prevented from rotating or rotating in the second direction at the same time. Typically, the process is accomplished using two separate wrenches or other fastener engagement tools, where one or more users attempt to manipulate a single fastener engagement tool to achieve the desired fastening or loosening. Unfortunately, the tool is easily moved from the fastener or the movement of the hands of one or more users interfering with each other, causing inconvenience and possible damage or damage to the fastener. In addition, when the fasteners are separated from the material, the difficulty of manipulating the two fasteners is greatly increased since the material makes it difficult for one or more users to see and / or reach the fastener. For this reason, time and resources are often wasted in the manipulation of the fastener.

Thus, the market requires a new type of device capable of simultaneously operating two fasteners having the same axis of rotation. The new device can operate the fastener at the same time to prevent the movement of one or more of the user's hands from interfering with each other, thereby preventing inconvenience and possible damage or damage to the fastener. The new device is also capable of simultaneously operating the fasteners of the same axis of rotation separated by the intermediate material. Finally, the new device should save time and resources.

    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.
