Abstract
A lampshade and lamp protection structure comprises a lampshade and a lamp base disposed therein. The lampshade has inside a snap ring, along which are provided with several connecting rods connected thereon. The other end of each connecting rod is connected to the cover body. The lamp base comprises a base body, whose top is provided with a snap base with a top surface having several claws. The inner side of the top of each claw has a barb matching the snap ring. The snap ring is inserted between the claws for the barbs to hold. The lamp base is connected to the snap ring through the snap base, and requires a tool to release. The lampshades of displayed lamps in a sale cannot be removed or interchanged easily. The wire therein is prevented from damages as it does not rotate when the lampshade and lamp base are separated.
