US Patent 7232596 Refined structure for artificial Christmas tree

The present invention is related to a technological field of decoration, and more particularly to a structure of an artificial tree, wherein the trunk main body has multiple sets of plugging holes, which are circularly arranged, longitudinally mounted thereon and the end terminals of the branches are plugged in the plugging holes. Because the branches are directly plugged into the plugging holes mounted on the trunk main body, the branch connecting elements and rivets which are served as medium components can be saved so that the structure of the artificial Christmas tree can be simplified, and correspondingly, the production procedure and the cost also can be reduced.
