37
from the locking recess
123
of the piston cylinder
12
.
At this time, the drive block
375
is moved with the clockwise rotated locking member
37
to push and move the push action block
362

, so that the press button
381
of the microswitch
38
may be pressed by the inclined press face
363
of the switch arm
36
, thereby opening the microswitch
38
which may start and operate the motor
21
which may counterclockwise rotate the force output gear
24
which meshes with and moves the rack
125
of the piston cylinder
12
, so as to move the piston cylinder
12
forward, thereby increasing the pressure in the cylinder
12
. Thus, the forward movement of the piston cylinder
12
may be accelerated by the restoring force of the piston spring
14
and by the power provided by the force output gear
24
co-operating with the rack
125
, whereby the BB bullet
108
located in the bullet feeding chamber
105
may be pushed forward by the pressure caused by the forward movement of the piston cylinder
12
, so that the BB bullet
108
may be ejected outward.

125
, thereby greatly increasing the pressure in the cylinder
11
, so that the BB bullet
108
may be ejected outward quickly and conveniently.
2. The locking lug
372
of the locking member
37
may be locked with the locking recess
123
of the piston cylinder
12
, so that the force output gear
24
and the rack
125
will not bear any load at a normal state, thereby saving the power source.
3. The piston cylinder
12
may be moved in the cylinder
11
freely, the force output gear
24
may mesh with and detach from the rack
125
easily, and the microswitch
38
may be opened by the switch arm
36
.
4. The force output gear
24
will not mesh with the rack
125
in a normal state, thereby decreasing the load of the motor
21
, and thereby increasing the lifetime of the toy gun.
5. As shown in
FIG. 4-1
, the trigger
31
may be pressed continuously, whereby the resting block insertion recess
353
of the connecting arm
35
is rested on the connecting arm resting block
341
of the lift member
