## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a Continuation-In-Part application of Ser. No. 10/202,812, filed 25 Jul. 2002 now U.S. Pat. No. 6,862,994, and entitled “ELECTRIC SHOCK GUN AND ELECTRODE BULLET.”


FIELD OF THE INVENTION
The present invention relates to an electric gun having a plurality of electrode bullets each have two electrodes in a form of a spine, both of which are powered by a capacitor in the bullet. The capacitor is charged within a short period of time by pulling the trigger.
BACKGROUND OF THE INVENTION
A conventional electric shock gun for ejecting two water beams is disclosed in FIG. 7, the gun has a pressurized tank 100 and two tanks 101 each filled with water are located in front of the pressurized tank 100. The two tanks 101 have two respective nozzles which are charged with high voltage so that when pulling the trigger 102, the two water beams are ejected out from the nozzles and may contact an animal or any conductive object and the current causes the animal to be paralytic or lost of ability of action. However, the pressure stored by the tanks can only send the water beams to a short distance and it will be a severe problem if the water leaks which could injury the user who holding the gun.
Another conventional electric shock gun 40 is shown in FIG. 8 and includes two electrode bullets 41, 42 wherein one of the two electrode bullets 41 is a positive electrode and the other 42 is a negative electrode so that when the two electrode bullets 41, 42 hit an animal or any conductive object, the electric current flows over the object and makes the object to be paralytic or loose the ability of action. The two electrode bullets 41, 42 are connected by two wires 410, 420 which transmit electric current to the two electrode bullets 41, 42. The wires 410, 420 have limited length which decides the range that the electrode bullets 41, 42 can reach. Besides, the animal is likely struggle from the electrode bullets 41, 42 and the wires 410, 420 could be broken and the broken wire de-effects the electrode bullets 41, 42.
The present invention intends to provide an electric shock gun for shooting electrode bullets each of which has a capacitor which is charged when pulling the trigger.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided an electric shock gun and electrode bullets are received in the gun. The gun comprises a firing device which includes an electric power source and a charging device. A plurality of electrode bullets are received in a magazine in the handle of the gun and each have two spines on a first end thereof and a conductive block on a second end. The firing device is electrically connected to the conductive block. Each electrode bullet includes a capacitor which is charged within a short period of time and connected to the spines and the conductive block.
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, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 to 4, the electric shock gun in accordance with the present invention comprises a gun 10 including a barrel 110, a trigger 15 and a handle 11 in which a magazine 12 is received. A firing device 13 is received in a rear end of the gun 10 and is activated by pulling the trigger 15. The firing device 13 includes a charging device 14 and an electric power source 140 which can be a rechargeable battery or an ordinary battery.
A plurality of electrode bullets 20 are received in the magazine 12 which is removably received in the handle 11 and a biasing member is located in an inside of the magazine 12 so as to push the electrode bullets 20 toward the barrel 110.
Each electrode bullet 20 includes a body 21 and a capacitor 22 is received in the body 21. The capacitor 22 includes a first board 220 and a second board 221 between which conductive agent 222 is received. Two spines 23, 24 extend from a first end of the body 21 and are connected to a positive port which is the first board 220 and a negative port 221 which is the second board 221 of the capacitor 22 respectively. A polygonal conductive block 25 is connected to a second end of the body 21 and two first opposite sides of the conductive block 25 are connected to the positive port 202 and two second opposite sides of the conductive block 25 are connected to the negative port 221 of the capacitor 22. The firing device 13 has a nose 30 which is located behind the conductive block 25 of the first electrode bullet 20 in the barrel 110 of the gun 10.
The firing device 13 further comprises a positive charging member 141 and a negative charging member 142 both of which are connected to the charging device 14 by two wires 1410 and 1420. The positive charging member 141 and the negative charging member 142 are connected to two positive plates 250 on the two first opposite sides of the conductive block 25 and two negative plates 251 on the two second opposite sides of the conductive block 25 respectively.
As shown in FIG. 5, when pulling a first stroke of the trigger 15, the capacitor 22 of the first electrode bullet 20 is charged within a short period of time by the charging device 14. When the trigger 15 is continued to be pulled, the firing device 13 is activated and the nose 130 strikes the conductive block 25 of the first electrode bullet 20 which is then shot out from the barrel 110. As shown in FIG. 6, the two spines 23, 24 penetrate into the skin of the object 30 which can be an animal or a criminal person. The two spines 23, 24 and the body of the animal or the criminal person form a circuit and the current “A” flows to the body of the animal or the criminal person via the two spines 23, 24.
The distance that the electrode bullets 20 reach is much far when compared with the distance of the electrode bullets from a conventional electric shock gun.
It is to be noted that the electrode bullets 20 are charged only before shooting so that the user does not be shocked by touching the spines 23, 24.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
