Abstract
A safety tensioning device includes a base, a handle, a winding mechanism and a first bundling strap. The first bundling strap is disposed on the main rotating shaft and the winding mechanism. The winding mechanism includes a box, a coil spring component and a winding shaft passing through the box with two ends exposed out of the box. One end of the winding shaft is attached to the coil spring component, a centrifugal self-locking mechanism to stop the winding shaft winding when a rotation speed is too fast, is attached to another end of the winding shaft.
