Upright Lamp Having Length Adjustable Lamp-Post

摘要

An upright lamp having length adjustable lamp-post includes a lamp-post, a plug mounted on the lamp-post, and a fastener configured for connecting the lamp-post and the plug. The lamp-post has a jack opened therein. The plug is inserted into the jack. The plug has a uniform cross section area and cross section shape with that of the jack. A hole is opened in the plug along axial direction thereof and is configured for receiving the fastener. The hole is intersected with a side wall of the plug. When the fastener is threaded into the volume formed by the plug and the lamp-post, the interference fit joint between the fastener and the volume is realized as the volume is less than that of the fastener. And then, the mounting base module and the fastener are assembled onto the lamp-post.
