When two opening ends 103 are oppositely arranged in the box body 100, one ends of the accommodating cavities 102 facing the two opening ends 103 are communicated with the corresponding opening ends 103, one ends of the first sliding grooves 105 facing the two opening ends 103 extend to the end faces of the corresponding opening ends 103, and two ends of the supporting plate 200 facing the two opening ends 103 are provided with abdicating notches 204.

In some preferred embodiments, the two ends of the supporting plate 200 facing the two open ends 103 are respectively provided with a relief notch 204, and the two relief notches 204 are arranged diagonally.

In the preferred embodiment, the two abdicating notches 204 on the support plate 200 are arranged diagonally, so that the center of gravity of the support plate 200 can be balanced to make the center of gravity near the middle of the support plate 200, thereby avoiding the situation that the support plate 200 is deformed in the magazine due to serious center of gravity shift.

In some preferred embodiments, the outer surface of the box 100 is provided with an image code for scanning by an external scanning device, and at least the cartridge number information is stored in the image code.

In the preferred embodiment, the image is encoded, for example, but not limited to, a two-dimensional code or a bar code. The image code stores cartridge number information including a cartridge number, a direction of the pointer 113, and the like. Staff's accessible scanning device scans the image code in order to obtain magazine serial number information, and then the staff of being convenient for confirms the magazine that required lead frame is located fast.
