[0006] Through the above technical solution, the effect of gradually pressing the cartridge can be achieved. The magazine is placed from one side of the crawler belt, and the bullets will slide along the slide plate to the side of the magazine. The crawler belt is controlled to rotate by inserting a handle or a motor into the rotating groove. In this way, the bullets will slide to the side of the empty magazine in sequence. At the same time, the first transmission gear will drive the second transmission gear to rotate, and then the second transmission gear will drive the pressing plate to swing through the connecting shaft. In the process of the movement of the bullets and the magazine, the bullets will gradually enter the magazine, thus completing the installation.

[0007] Preferably, the surface of the pressing plate is Z-shaped, and its width gradually increases from the inlet to the outlet of the transmission device.

[0008] Through the above technical solution, the effect that the bullet gradually enters the magazine can be achieved. The pressing plate is Z-shaped, so that when the bullet passes through the inclined side of the pressing plate, it can be gradually pressed into the magazine.

[0009] Preferably, the crawler belt includes a plurality of chain plates that are rotatably connected to each other, and tooth teeth are fixedly connected to the outer wall of the bottom of each chain plate.

[0010] Through the above technical solution, the function of linkage can be achieved. The tooth teeth at the bottom of the chain plate can be engaged with the gear. In this way, when the limiting wheel rotates, the chain plate is driven to move, so that the chain plate can move in a cycle.

[0011] Preferably, a first limiting block is fixedly connected to the outer wall of each chain plate, and the outer wall of the first limiting block is used for limiting the magazine.

[0012] Through the above technical solution, the limiting function can be achieved. Through the arc-shaped groove on the first limiting block, the magazine can be limited, so that the magazine can move stably.

[0013] Preferably, a second limiting block is fixedly connected to the outer wall of each chain plate, and the outer wall of the first limiting block is used for limiting the bullet.

[0014] Through the above technical solution, the limiting function can be achieved. Through the arc-shaped groove on the second limiting block, the bullet can be limited, so that the bullet can move stably.

[0015] Preferably, a moving plate is slidably connected to the inner wall of the second limiting block, and connecting ears are fixed to the outer walls on both sides of the chain plate.

[0016] Through the above technical solution, the function of stabilizing the bullet can be achieved. The moving plate extends outwards by a section, which can make the bullet placed more stably. And the moving plate can be extruded and moved towards the magazine side against the pressing plate, so that the moving plate will not limit the pressing plate. At the same time, the moving plate is reset by the spring inside, and the friction force with the bullet during reset will not draw the bullet out of the magazine.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. Insert the magazine from one side of the track. The bullets will slide along the skateboard and fall beside the magazine. Control the rotation of the track by inserting and rotating it into the rotation slot through the handle or motor. In this way, the bullets will slide beside the empty magazine in sequence. At the same time, the first transmission gear will drive the second transmission gear to rotate. Thus, the second transmission gear will drive the pressure plate to swing through the coupling shaft. During the movement of the bullets and the magazine, the bullets will gradually enter the magazine, completing the installation. The pressure plate is Z-shaped, allowing the bullets to be gradually pressed into the magazine when passing through the inclined side of the pressure plate.

[0018] 2. The teeth at the bottom of the chain plate can mesh with the gear. When the limiting wheel rotates, it drives the chain plate to move, enabling the chain plate to move in a cycle. Through the arc-shaped groove on the first limiting block and the arc-shaped groove on the second limiting block, the bullets can be limited, ensuring their stable movement. The moving plate extends outwards by a section, making the placement of the bullets more stable. Moreover, the moving plate can squeeze and move towards the magazine side against the pressure plate, so that the moving plate will not limit the pressure plate. At the same time, the moving plate is reset by the internal spring, and the frictional force with the bullet during reset will not pull the bullet out of the magazine.
