[0035] Working principle: When using the polyolefin turnover box and it is necessary to adjust the space inside the box body 1, rotate the adjusting ring 13 to rotate the threaded rod 12, thereby driving the two adjusting blocks 14 to slide inside the second sliding groove 11, and then pushing the two clamping plates 10 to adjust the distance between the two clamping plates 10, so as to adjust the space inside the box body 1. At the same time that the two clamping plates 10 push the sliding block 7 and the connecting rod 8 by the buffer spring 6, they will also closely adhere to the goods. When the box body 1 shakes, the clamping plates 10 can also push the sliding block 7 through the connecting seat 9 and the connecting rod 8 to squeeze the buffer spring 6, realizing the buffering inside. By buffering the goods inside the box body 1 while adjusting the space inside the box body 1, the impact on the goods during transportation is reduced, thereby reducing the risk of damage and breakage of the goods. The fan 4 at the bottom end inside the box body 1 can accelerate the air circulation inside the box body 1 and keep the inside of the box body 1 dry when transporting goods. After the fan 4 is used for a long time, it needs to be maintained. By grasping the clamping block 20 with the hand, when the clamping block 20 drives the pushing piece 19 to squeeze the pushing spring 18 through the connecting column 17, it leaves the clamping groove 15 and no longer engages with the clamping groove 15, and rotates it so that it does not block the bottom plate 3. At this time, the bottom plate 3 and the fan 4 can be taken out from the inside of the box body 1. After the fan 4 is maintained, it is re-placed at the bottom end inside the box body 1, and the clamping block 20 is re-engaged inside the clamping groove 15. The pushing spring 18 will push the pushing piece 19, thereby driving the clamping block 20 to firmly engage inside the clamping groove 15. By quickly disassembling the bottom plate 3, it is easier to maintain the fan 4, reducing the maintenance process and improving the work efficiency of the maintenance work.
