发明名称 Adjustable tree stand frame
摘要 An adjustable tree stand frame has a housing attached to a tree with a spindle rotatably disposed within the housing. One or more spring loaded pins are removably receivable within openings on an outer periphery of the spindle such that when so received within an opening, spindle rotation is prevented. A frame is pivotally attached to the spindle and uses a threaded shaft and a receiver to pivot the frame back and forth with respect to the spindle.
