ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to a nozzle, and more particularly to a spray nozzle that can be installed quickly.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a prior art spray nozzle consists of a nozzle holder
10
and a nozzle head
11
which are engaged with each other. At the top of the nozzle holder
10
near to the water outlet
12
is formed an external thread
13
, whereas inside of the nozzle head
11
is formed an internal thread. While changing or installing the nozzle head
11
, the user will need to spend more time in swiveling between the nozzle head
11
and the nozzle holder
10
so as to engage with the water outlet
12
.
Such a design is defective in that it is waste of time and needs to change the shapes of the nozzle head if the spray nozzle is required to have different forms and ranges in spraying.
SUMMARY OF THE INVENTION
The primary objective of the present invention is therefore to provide a quickly installed spray nozzle with a special device to the connect tube of the top nozzle holder and to the casing of the opposite nozzle head.
