Abstract

A link rod type adjustable screen fixing apparatus includes: a fixing base, having at least one operating slot; at least one distal plate device, having at least one pair of distal plates embedded in the operating slot, and slidably moving in the operating slot, and an upper frame plate disposed at an external side of the distal plate; at least one contractible device, formed by pivotally coupling link rods, and installed in the operating slot, and a side of the contractible device being pivotally coupled to the distal plate; and a containing space, defined by the upper frame plate of the distal plates for installing a screen. The distal plate is contractible in the operating slot for adjusting the containing space, such that the invention can fit screens of different sizes, and provide a convenient replacement and a dynamic adjustment.

Claims
