The support arm (42) includes a rotating rod one (421) and a rotating rod two (422). One end of the rotating rod one (421) and the rotating rod two (422) are rotatably connected. The end of the rotating rod one (421) away from the rotating rod two (422) is rotatably connected to the base frame (11). The end of the rotating rod two (422) away from the rotating rod one (421) is rotatably connected to the rotating leg (41). A pull rope two (34) is provided at the position where the rotating rod one (421) and the rotating rod two (422) are rotatably connected. A fixed pulley two (32) is rotatably connected to the base frame (11). One end of the pull rope two (34) is driven by the transmission device (6) after passing through the fixed pulley two (32). A turntable (44) is provided in the middle of the base frame (11). The end of the second pull rope (34) away from the support arm (42) is fixed to the edge of the turntable (44). The connection points of the two second pull ropes (34) connected to the same turntable (44) and the turntable (44) are symmetrical about the center of the turntable (44). The transmission device (6) includes a transmission worm (61) and a transmission worm wheel (62), which mesh with each other. The transmission worm wheel (62) is coaxially fixed with the turntable (44). The transmission worm (61) is rotatably connected to the mounting bracket (63) which is fixed relative to the base frame (11). The winding device (5) includes a winding worm (51) and a winding worm wheel (52), which mesh with each other. A winding wheel (53) is coaxially fixedly connected to the winding worm wheel (52). The pull rope (33) is used to be installed on the winding wheel (53). The drive device (7) includes a drive gear (71), a drive rod (73), and a driven gear (72). The drive rod (73) is rotatably connected to the base frame (11) and slides relative to the base frame (11) along the length direction of the drive rod (73). The drive gear (71) is coaxially fixed on the drive rod (73). A driven gear (72) is coaxially fixed on the transmission worm (61). A driven gear (72) is coaxially fixed on the winding worm (51). The two driven gears (72) are staggered relative to each other along the length direction of the drive rod (73). The drive gear (71) is used to mesh with the two driven gears (72) in sequence.

2. The multifunctional logistics storage box according to claim 1, characterized in that: The inner side of the side plate (12) is rotatably connected to the base frame (11). When the base plate (13) moves downward to below the side plate (12), the side plate (12) folds towards the center of the base frame (11). When the base plate (13) moves upward to the position of the side plate (12), the edge of the base plate (13) abuts against the inner surface of the side plate (12).

3. A method for manufacturing a multifunctional logistics storage box, used to manufacture a multifunctional logistics storage box according to any one of claims 1-2, characterized in that: This includes installing four lifting devices (2) and four rotating legs (41) on the base frame (11), and adjusting the length of multiple pull ropes (33) connected to the lifting devices (2) to the same length when the lifting height of the four lifting devices (2) is adjusted to the same position; when the rotating leg (41) rotates to the position supporting the base frame (11), adjusting the length of the pull rope (34) controlling the rotation angle of the rotating leg (41) to the same length.
