Collapsible christmas tree

Abstract

A collapsible Christmas tree has a main trunk, a base, and multiple string lights. The main trunk is telescopic. The base is detachably mounted on a bottom end of the main trunk. The string lights are connected to the main trunk and the base. Two ends of each string light are respectively connected to a top end of the main trunk and the base. The main trunk and the base can be disassembled from each other. Additionally, the main trunk is telescopic, such that the overall volume can be further reduced when the collapsible Christmas tree is folded. As a result, the collapsible Christmas tree is convenient both for storage and transportation.
