The clamping column 40 is in conflict with the logistics goods. Through the movable installation of the mounting frame 39, the irregular logistics goods can be clamped and fixed, so that the stability is improved. When the top area of ​​the placement table 5 is insufficient, the third motor 28 is driven to drive the transmission gear 29 to rotate, so that the transmission gear 29 drives the first transmission rack plate 30 and the second transmission rack plate 31 to move to both sides, and drives the first fixed rod 32 and the second fixed rod 33 connected at one end to extend out of the placement table 5, so that the extension plate 6 connected at one end of the first fixed rod 32 and the second fixed rod 33 extends along the placement table 5 to both ends, so that the placement area is increased. When it rains, the U-shaped The scaffolding 54 and the tarpaulin 55 are unfolded to shield the logistic goods fixed on the top of the placing platform 5 from rain, so as to prevent the logistic goods from being wetted by rain during transportation. At the same time, the U-shaped scaffolding 54 and the sliding seat 53 can be telescopically adjusted in height, so that the U-shaped scaffolding 54 and the tarpaulin 55 can adapt to logistic goods of different sizes, thereby improving practicality and improving the efficiency of logistic goods transportation. When the logistic goods on the placing platform 5 are unloaded, the second motor 22 is driven to make the driving gear 21 installed at the output end drive the driven gear 20 to rotate, so that the shaft rod 19 rotates to drive one end of the first hydraulic rod 17 to lift up, and lift up the placing platform 5, and then drive the first hydraulic rod 17 to lift up. The pressure rod 17 can drive the placement table 5 to rotate and tilt to a certain angle along the lifting plate 4 through the connecting head 23 and the connecting seat 24, and at the same time drive the second hydraulic rod 44 to drive the second inclined plate 42 to move outward along the inside of the first inclined plate 41, so that the angle between the first inclined plate 41 and the second inclined plate 42 is raised, so that the logistics goods can be unloaded more smoothly. When the logistics goods are unloaded to the top of the receiving seat 45, the spring rod 46 and the buffer plate 47 installed on the side wall of the receiving seat 45 can buffer the logistics goods to avoid damage during unloading, and then drive the fourth motor 49 to drive the screw rod 48 to rotate, so that the push plate 50 slides along the groove to push the logistics goods out, thereby completing the unloading and increasing the unloading speed.
