An electric toy gun comprising a casing having a room therein, the casing having a rear end with a through hole communicating with the room; a firing mechanism disposed in the room, the firing mechanism having a piston corresponding to the through hole; a guide pipe coupled at the rear end of the casing and communicating with the through hole; a hit rod movably disposed in the guide pipe, the hit rod having a first end and a second end, the first end of the hit rod passing through the through hole and being located in the room, the second end of the hit rod being coupled with a weight; a first elastic member disposed in the room, a first end of the first elastic member abutting against the piston and a second end of the first elastic member abutting against the hit rod; and a second elastic member disposed in the guide pipe, a first end of the second elastic member abutting against the casing and a second end of the second elastic member abutting against the weight; said electric toy gun structure further comprising a claw disposed inside the piston and being configured for releasably catching the first end of the hit rod, wherein, when the claw catches the first end of the hit rod, the piston is pushed forwards through the elastic force of the first elastic member and the hit rod and weight are synchronously moved to compress the second elastic member, and, when the claw releases the first end of the hit rod, the hit rod and weight are pushed backwards through the elastic force of the first and second elastic member (6, 7), for the weight of the hit rod to hit an end plug coupled to the rear end of the guide pipe. a casing having a room therein, the casing having a rear end with a through hole communicating with the room; a firing mechanism disposed in the room, the firing mechanism having a piston corresponding to the through hole; a guide pipe coupled at the rear end of the casing and communicating with the through hole; a hit rod movably disposed in the guide pipe, the hit rod having a first end and a second end, the first end of the hit rod passing through the through hole and being located in the room, the second end of the hit rod being coupled with a weight; a first elastic member disposed in the room, a first end of the first elastic member abutting against the piston and a second end of the first elastic member abutting against the hit rod; and a second elastic member disposed in the guide pipe, a first end of the second elastic member abutting against the casing and a second end of the second elastic member abutting against the weight; said electric toy gun structure further comprising a claw disposed inside the piston and being configured for releasably catching the first end of the hit rod, wherein, when the claw catches the first end of the hit rod, the piston is pushed forwards through the elastic force of the first elastic member and the hit rod and weight are synchronously moved to compress the second elastic member, and, when the claw releases the first end of the hit rod, the hit rod and weight are pushed backwards through the elastic force of the first and second elastic member (6, 7), for the weight of the hit rod to hit an end plug coupled to the rear end of the guide pipe.
