[0031] Reference Figure 4 Multiple connecting rods 204 are hinged to multiple sliders 205 respectively, and one end of multiple springs 207 is fixedly connected to multiple connecting rods 204 respectively.

[0032] Specifically, the hinged connection allows the connecting rod 204 to rotate when its upper end moves downward, thereby pushing the connecting rod 204 to compress the spring 207.

[0033] Reference Figure 1 Each of the two box lids 3 has a buckle fixedly installed at the center of its upper surface, and the two box lids 3 are slidably installed at the front and rear ends of the upper surface of the main body of the packaging box 1.

[0034] Specifically, the latches can be used to fix the positions of the two lids 3 after they have moved and closed relative to each other.

[0035] Reference Figure 1 , Figure 2 The main body of the packaging box 1 is composed of multiple brackets and multiple bolts, and all the brackets are made of 430 stainless steel.

[0036] Specifically, the main body 1 of the packaging box, which is assembled by brackets and bolts, can replace the four-sided closed packaging box, thereby reducing the overall weight. At the same time, the bracket made of 403 stainless steel can provide excellent corrosion resistance, thus extending the disposal cycle of the main body 1 of the packaging box.

[0037] Reference Figure 1 , Figure 2 Multiple support frames are fixedly installed on both sides and the bottom of the inner wall of the main body 1 of the packaging box. All support frames are made of 403 stainless steel.
