[0002] During the grenade launching process, in order to achieve multi-directional and effective strikes on the target, the grenade launcher is usually hung on an aircraft such as a drone, and grenades are continuously launched at high altitudes to strike the target. However, during the grenade launching process, the existing launcher is prone to cause damage to the drone or other aircraft due to the recoil generated when the grenade is launched, affecting the aircraft's mid-air flight and making it impossible to accurately strike the target. Moreover, most of the existing launchers have one launcher corresponding to one grenade warhead, which greatly limits the aircraft's ammunition load. Summary of the invention

[0003] In view of this, the present invention aims to provide a magazine of a multiple-warhead grenade launcher, so that the same launcher can carry multiple grenades and reduce the space required for mounting the grenades.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0012] Furthermore, a striker seat is provided on the wheel disc, the striker hole is a stepped hole, and a return spring is built into the striker hole, the striker includes a striking part and a primer triggering part, and the diameter of the striking part is larger than the primer triggering part, so that a shoulder is formed between the primer triggering part and the striking part, and one end of the return spring abuts against the shoulder, and the other end abuts against the step.

[0013] Furthermore, the side wall of the impact part is provided with a section along the length direction, the bottom end of the section is tangent to a limiting arc surface, a limiting hole is provided on the striker seat along the chord direction, a limiting shaft passes through the limiting hole, and when the reset spring is in a relaxed state, the limiting arc surface presses against the side wall of the limiting shaft.
