发明名称 Tree stand
摘要 A tree stand comprises a rigid base; a plurality of resilient bars each having a bend and a first portion extending substantially vertically downwardly from the bend and terminating in a free end. The first bar portions are arranged in a circular array and together define a generally cylindrical shaft for receiving the trunk of a tree and holding the same by a resilient clamping force. Each resilient bar further has a second portion extending from the respective bend obliquely downwardly and away from the shaft and is affixed to the base.
