  • Patent number: 7364130
    Abstract: An improved artificial Christmas tree stand includes a first unit and a second unit. A fixed piece is provided on a top portion of the first unit, and an upper hole is centrally provided in the fixed piece. A moveable piece is provided on each first and second unit, and a hole is centrally provided in the moveable piece. A substantially rectangular hole is provided on the moveable piece. A locking element is connected to the moveable piece of the second unit and has a locking portion. When the stand is not in use, we can disengage the locking portion from two substantially rectangular holes and rotate the first unit with respect to the second unit for a certain angle until they press against each other. Now, the folded stand may be easily stored away.

  • Patent number: 7232596
    Abstract: 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.

The holding tube assembly composes of an inside sleeve and a bushing which are held within an outside sleeve. There is a protection sleeve disposed within the inside sleeve to allow an electric wire disposed therebetween. A motor is disposed at the bottom of the outside sleeve. The motor can drive the inside sleeve and the bushing to rotate through a gear mechanism. Thereby the Christmas tree or the pole being disposed within the inside sleeve can also be rotated when motor is power on.
