ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a water sprinkler, and more particularly to a nozzle of the water sprinkler.
2. Description of Related Art
As shown in
FIG. 1
, a prior art nozzle
10
of the sprinkler comprises a pipe
11
which is fastened at one end with a head
12
, and at another end to a grip
13
. The prior art nozzle
10
is defective in design because the pipe
11
cannot be adjusted in length, and because the head
12
is fixedly fastened to the pipe
11
. In other words, the prior art nozzle
10
has a fixed length, thereby making it costly to store or ship the prior art nozzle
10
.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a sprinkler with a nozzle which is free of the shortcomings of the prior art nozzle described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by an improved nozzle which comprises a head, an expandable pipe, and a grip. The head is rotatably fastened to one end of the expandable pipe, whereas the grip is fastened to the other end of the expandable pipe.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
