the connecting member 221 further includes a second inclined portion 221b having an inclination angle corresponding to the first inclined portion 224b, the first inclined portion 224b presses down on the second inclined portion 221b, and when the first inclined portion 224b moves backward under the driving of the pulling portion 224a, the first inclined portion 224b slides on the second inclined portion 221b to press down the second inclined portion 221b, so as to drive the connecting portion to move downward, so that the first hook 221a is disengaged from the second hook 222 c. In use, a person pulls the pulling part 224a to compress the trigger spring 225 backwards, the first inclined part 224b slides backwards relative to the second inclined part 221b pressed by the first inclined part 224a, the connecting part 221 moves downwards during the relative sliding process, and the first hook 221a on the connecting part 221 moves downwards along with the first inclined part, so that the first hook is separated from the second hook 222c above. After the limitation of the first hook 221a is lost, the pushing member 222 moves rapidly toward the magazine 21 by the elastic force of the pushing spring 223, and if the corresponding magazine 21 has the projectile 1, the projectile 1 can be ejected forward by the pushing member 222.

Based on the structure of the transmitter and the human engineering principle, the sliding switch and the micro switch in the embodiment are both arranged on the left side of the shell, and particularly the micro switch is arranged on the right side of the pulling part and is positioned at the position where the thumb of a human hand can press. The arrangement of the switch enables a hand to hold the launcher with the right hand and wait for the trigger part to be buckled, the sliding switch can be conveniently opened by the left hand in a sliding way, and the micro switch can be opened by being touched by the thumb, so that the use habit of ordinary people is met, and the effect of igniting the smoke agent in the projectile body is rapidly realized. For safety, it is preferred that the trigger be actuated immediately after the microswitch is depressed to expel the projectile so as not to over burn in the projectile.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
