发明名称 Self-clamping christmas tree stand
摘要 A self-clamping Christmas tree stand provides a stable platform for a Christmas tree that allows simple installation and adjustment of the tree angle without having to be positioned under the tree to perform the adjustments. The tree stand uses the weight of the tree to firmly clamp the tree's trunk. A clamping mechanism provides a constant grip that will not loosen unless an upward force is provided by the user. The adjustment range of the tree trunk angle with respect to the vertical plane may be varied to accommodate tree trunks of different shapes. Lastly, the tree stand includes a large liquid reservoir to maintain the tree's moisture content.
