发明名称 Artificial Christmas tree stand
摘要 The stand is of a general hemispheric configuration. It is dimensioned with an adapter to handle a broad range of stem sizes and heights of artificial Christmas trees. A principal feature of the stand is the quick mounting and quick release that is made possible by the adapter which is readily expanded or reduced in its diameter when the tree trunk is inserted or removed.
