发明名称 Adjustable high water capacity tree stand
摘要 The present invention relates to an adjustable high water capacity tree stand having a wide base and an increased water carrying capacity. In a preferred embodiment, the stand has a generally inverted conical shape. A plurality of base plates engage the bottom of the tree truck to prevent slipping. A plurality of compression assemblies are also provided. The compression assemblies can move in and out relative the tree trunk under operation of a rod. The rod can be a screw rod that drives a translator, which in turn is pivotally connected to a ram. The ram is pivotally connected to an arm and causes the arm to pivot. The arm is pivotally connected to a head, and operates to selectively move the head in and out. The head, being pivotally connected to the arm, can flushly engage the tree trunk near its bottom.
