An elastic layer 3 is fixedly arranged on the bottom wall and three adjacent side walls of the box body 1. The elastic layer 3 is a sponge layer, which can buffer the collision to a certain extent. The elastic layer 3 arranged on the side wall of the box body 1 where the partition 6 is located is in the shape of a vertical strip, which is fixedly arranged on the side wall of each storage area 7 to protect the lead frame placed inside the storage area 7. An elastic layer 3 and an airbag 11 are fixedly arranged on both sides of each storage area 7, respectively, and the airbag 11 can be flexibly fixed to lead frames with different appearances.
