The connecting member consists of an upper fastening bar transversely positioned on the bottom of each post of the up per fence, a lower fastening bar also transversely positioned on the top of each post of the lower fence, and a connecting tube that is cut with an inserting groove in its bottom and plural holes bored on its top respectively for each post of the upper fence to insert. Two positioning segments are formed inside the connecting tube to respectively fix with the upper fastening bar and the lower fastening bar. A connecting pin has its two ends respectively inserted into each post of the upper fence and also each post of the lower fence to keep the two posts joined together. Thus, the fence can be easily assembled and raised with its height without discarding original posts. (end of abstract)

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a fence, particularly to one having its screws invisibly installed, and its upper fence and its lower fence conveniently assembled together.

2. Description of the Prior Art

Commonly, a conventional fence or the like made of metal is composed of plural rails (at least an upper one and a lower one), and plural posts cross-linked with the rails. Each intersection of the rails and the posts is fastened by a screw. But, if the fence is to be heightened, it is always done either by replacing the posts with longer ones, posing a high cost, or by being welded with additional posts, possible to smear the fence.

SUMMARY OF THE INVENTION

The objective of this invention is to offer a fence able to be easily assembled and raised with height.
