At this time, the expansion The support push rod 16 rotates and moves downward synchronously with the fixing screw 14. When the conical surface of the expansion push rod 16 contacts the plurality of deformed clips 15, the plurality of deformed clips 15 are pushed and squeezed to the four sides by the expansion push rod 16, so that the plurality of deformed clips 15 are respectively pressed and abutted against the side surfaces of the positioning slots 12, so as to prevent the plastic corner protector 6 from easily detaching from the packaging box support foot 2 during later transportation and use, thereby improving the connection strength of the entire box body. When the fixing screw 14 is rotated, the entire box body can be supported by a raising platform or a pallet. After the packaging box support foot 2, the plastic corner protector 6 and the multi-layer corrugated side panel 7 are assembled, the buffering and shock-absorbing corrugated sleeve 20 contacts the ground, so that there can be a certain gap between the bottom of the multi-layer corrugated lower cover plate 1 and the packaging box support foot 2 and the ground, thereby reducing the bumps and vibrations during transportation.

The fixed screw 14 is controlled to rotate through the hexagonal screw head 18, and the hexagonal screw head 18 is inserted into the assembly threaded ring 17. The assembly threaded ring 17 can be used as an adjustment support for the upper and lower heights of the combined support seat 21. When the buffer and shock-absorbing corrugated sleeve 20 is used as a buffer and shock-absorbing or is placed stably, the combined support seat 21 is retracted into the buffer and shock-absorbing corrugated sleeve 20 through the threaded rotation of the assembly threaded ring 17; When it is difficult to carry the multi-layer corrugated lower cover 1 over a short distance and it is inconvenient to use the carrying and lifting equipment, the four feet of the box can be slightly padded in turn, and then a rod or a screwdriver can be inserted through the adjustment window 25 and inserted into the toggle slot 24, and then the combined support seat 21 can be rotated and moved along the adjustment window 25, so that the combined support seat 21 can move up and down on the assembly threaded ring 17, so that the moving ball 23 can extend out of the buffering and shock-absorbing corrugated sleeve 20. When the moving ball 23 rolls in contact with the ground, the packaging box can be moved a short distance by pushing it horizontally.
