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.

Claims

1. A refined structure of an artificial Christmas tree comprising:

a trunk main body including multiple sets of plugging holes longitudinally formed thereon each set of plugging holes including at least two pairs of holes circularly arranged and;

at least two L-shaped branches, each with one shorter end plugged in and passing through corresponding one pair of holes so that two branches are mutually stacked and pressed together.

2. The structure according to claim 1, wherein said plugging holes include “

8”

-shaped and “

0”

-shaped holes mutually staggered in height, and each “

8”

-shaped or “

0”

-shaped hole has a guiding channel and each branch has a blocking protruding point formed on the shorter end to match with said guiding channel so that the branch is prevented from receding after penetrating out from the plugging hole and stacked with another branch.

3. The structure according to claim 1, wherein said plugging holes all have a shape of “

0” and

are staggered in height, and each branch has a deformed bend formed at the shorter end for preventing each branch from receding after penetrating out from the plugging hole.

4. The structure according to claim 1, wherein said trunk main body is composed of multiple sections by mutually plugging and sleeving two adjacent sections together.

5. The structure according to claim 2, wherein said trunk main body is composed of multiple sections by mutually plugging and sleeving two adjacent sections together.

6. The structure according to claim 3, wherein said trunk main body is composed of multiple sections by mutually plugging and sleeving two adjacent sections together.
