Device adapted for toy launcher projectile and toy gun

A projectile launching device, comprising:

• a launching tube for receiving a projectile;
• a cavity, located at an end portion of the launching tube for compressing air to catapult the projectile from the launching tube;
• a seat, located between the launching tube and the cavity, a surface of the seat facing toward the launching tube, the seat including a front cover and a chassis carrying a projection for contacting a bottom of the projectile to sense when the projectile is positioned in the launching tube causing the projection to move rearwardly, the front cover having a hole through which the projection extends;
• a catapulting rod, comprising a longitudinal rod having a head end extending into the cavity to cause the air to be compressed when the catapulting rod is moved toward the launching tube and a vertical rod connected to a tail end of the longitudinal rod, the longitudinal rod being equipped with a holding member;
• a first rod, mechanically separate from the catapulting rod, having one end equipped with a first portion, the first portion contacting the vertical rod of the catapulting rod to pull the catapulting rod back to a cocked position;
• a catapulting rod stopper equipped with a first through hole for the longitudinal rod of the catapulting rod to pass through, one edge of the first through hole being matched with the holding member in the catapulting rod to hold the catapulting rod in the cocked position;
• a rod assembly having a first end connected with the seat and a second end connected with the catapulting rod stopper, so as to prevent the catapulting rod from moving toward the launching tube unless the projectile is positioned in the launching tube;
• and
• the rod assembly including a third rod, a fourth rod and a fifth rod;
• the fifth rod being connected to the chassis, so as to rotate when the projection moves rearwardly, sensing the projectile;
• the third rod being rotatively connected to the fifth rod, so as to rotate when the fifth rod rotates in response to the projection moving rearwardly when sensing the projectile;
• the fourth rod being connected to the third rod so as to move forwardly when the third rod rotates, the fourth rod having a boss at the second end of the rod assembly, the boss being disconnected from the catapulting rod stopper when the fourth rod moves forwardly when the projectile is sensed by the projection.
