ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a grease dispensing gun wherein the handle and the barrel of the grease gun can be pivoted with each other so as to meet the requirements when in use.
BACKGROUND OF THE INVENTION
A conventional grease dispensing gun
10
is shown in FIG.
1
and generally includes a handle
13
with a trigger means
131
, a barrel
12
connected to the handle
13
and a container
14
connected to the barrel
12
of the grease gun. The container
14
receives grease therein so as to be provided into the barrel
12
and dispensed form a nozzle member
11
connected to a front end of the barrel
11
. A piston
121
connected to a piston rod is received in the barrel
12
and a spring
122
is mounted to the piston rod so that when pulling the trigger means
131
, the air pressure provided from a fitting connected to a lower end of the handle
13
will send the grease
14
out from the nozzle member
11
. However, because the barrel
12
, the handle
13
and the container
14
are made to be an one-piece member, so that the user sometimes has to rotate the whole grease gun to access a desired position because the space where the desired position does not allow the container
14
to be inserted. The user's hand turns an angle to hold the handle
13
and this will affect the aim of the nozzle member
11
.
The present invention intends to provide a grease dispensing gun wherein a bolt is used to connect the barrel and the handle so that the barrel can be rotated to shift the position of the container on the barrel.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a grease dispensing gun and comprising a handle having a trigger device and a fitting respectively connected thereto. A connection member is connected to a top end of the handle and a barrel is rotatably engaged with an inner periphery of the connection member at its first end. A nozzle member is connected to a second end of the barrel and a container is connected to the nozzle member. A board is connected to the first end of the barrel and a bolt extends through the connection member and is engaged with the board.
The primary object of the present invention is to provide a grease dispensing gun wherein the barrel together with the container can be rotated relative to the handle.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
