ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a paintball gun, particularly to one capable of adjusting an adjusting screw disposed in a back of a grip to make an inner end of the adjusting screw push a magnetic-attraction plate slightly forward or backward so as to adjust the displacement height of a locking member for being fitted with different types of gun bodies, by which a single grip is suited for being assembled with a gun body of different style to decrease the manufacturing of gun bodies with varied styles and lower the production cost.
2. Description of the Prior Art
A known conventional paintball gun, as shown in
FIG. 1
, mainly includes a grip
1
and a gun body
2
. A recess
10
is disposed inside the grip
1
and provided with a circuit board
11
and an electromagnet
12
therein. A chamber
13
disposed above the recess
10
and communicated with the recess
10
is provided with an electromagnetic valve
14
therein. A magnetic-attraction plate
15
disposed at one side of the electromagnetic valve
14
has a push rod
150
extended through the electromagnetic valve
14
and protruded from the other side of the electromagnetic valve
14
. A locking member
16
pivoted on an upper portion of the grip
1
has an upper end whose bottom is urged upward by a spring
17
disposed below and a lower end pushed against by an outer end of the push rod
150
. A trigger
18
disposed in front of the grip
1
has an actuator
19
located in back of the trigger
18
. The grip I is fixed beneath the gun body
2
. The gun body
2
has a slide way
20
disposed at a bottom of the gun body
2
for accommodating the upper end of the locking member
16
, an air chamber
21
provided with a recoil rod
22
therein. A locking groove
23
is formed at a bottom of the recoil rod
22
for firmly engaging the locking member
16
. A firing chamber
24
located above the air chamber
21
has a pull rod
25
disposed at a rear of the firing chamber
24
and provided with a linking rod
26
connected with the recoil rod
22
, by which a pull of the pull rod
25
will make the recoil rod
22
moved accordingly.
However, the known conventional paintball gun has the locking member
16
of the grip
1
with a fixed height in its engaging position hard to be make any adjustment, which is only suited for being combined with one specific gun body
2
. In case of being combined with a different gun body
2
, a fitted grip
1
is required and thus greatly increases the production cost.
SUMMARY OF THE INVENTION
The main purpose of the invention is to offer a paintball gun capable of having a single grip suited for being assembled with a gun body of different style.
The main feature of the invention is to provide a paintball gun having a screw hole formed in a back of a grip and extended through a chamber for being screwed with an adjusting screw whose inner end is protruded into the chamber and pressed against one sidewall surface of a magnetic-attraction plate.
