发明名称 Tree step
摘要 The screw at the upper end of the bracket leg is screwed into a tree to support the bracket with the step extending horizontally. When detached the screw can be folded into the leg and moved to a position preventing pivoting the screw relative to the leg. The bracket can now be folded. The screw can also be positioned to extend axially from the leg while unable to pivot with respect to the bracket so the folded bracket serves as a handle for the screw.
