the method comprises the following steps: as shown in fig. 1 and 2, when placing the goods with a smaller volume, that is, a single supporting plate 15 can support and place the goods, at this time, the second supporting rod 13 needs to be folded into a vertical state from a horizontal state, the motor and the electromagnetic plate 40 are controlled by the controller to be powered on, as shown in fig. 6 and 7, the electromagnetic plate 40 is powered on to generate electromagnetic attraction and attract and fix the iron plate 39, so that the iron plate 39 drives the toothed plate 35 to move downwards through the multi-edge rod 38 and separate from the gear 34 without contact, and meanwhile, the toothed plate 35 compresses the spring three 36 to obtain restoring force, so as to unlock the second supporting rod 13.

The motor drives the first winding roll 8 to rotate through the first rotating shaft 7, so that the first winding roll 8 winds the pull rope 12, the pull rope 12 applies a pulling force to the second supporting rod 13 to enable the second supporting rod 13 to move from a horizontal state to a vertical state, the first supporting rod 4, the second supporting rod 13 and the connecting rod 14 form a parallel four-bar linkage mechanism, so that the shape of the connecting rod 14 is unchanged along with the movement process of the second supporting rod 13 according to the movement track of the parallel four-bar linkage mechanism, the shape of the supporting plate 15 is unchanged, the supporting plate is rotated to a horizontal state arranged from the same horizontal plane to the top and bottom, when the second supporting rod 13 is in abutting contact with the first touch switch 11, the first touch switch 11 transmits a touch signal of the second supporting rod 13 to the controller, the controller controls the motor and the electromagnetic plate 40 to be powered off and not work, the electromagnetic plate 40 loses the electromagnetic suction force on the iron plate 39 after being powered off, and accordingly the toothed plate 35 is driven to be meshed with the gear 34, therefore, the second supporting rod 13 is locked, the second supporting rod 13 is prevented from automatically rotating downwards under the action of gravity of goods, the goods are kept stable and safe when placed, the occupation of the transverse space of a goods shelf is reduced, the space utilization efficiency is improved, the toothed plate 35 moves upwards and drives the iron plate 39 to move upwards and reset through the multi-edge rod 38, the multi-edge rod 38 is adopted to prevent the toothed plate 35 from rotating in the up-and-down moving process and being incapable of being meshed with the gear 34, the working stability of the safety protection mechanism is ensured, in the rotating process of the second supporting rod 13 from the horizontal state to the vertical state, the second winding disc 9 winds the safety rope 33 under the action force of the coil spring 17, so that the safety rope 33 is always in a tight state, the timely safety protection effect can be achieved, and the wire guide wheel 10 is used for preventing the safety rope 33 and the pull rope 12 from winding;

step two: when a large-size cargo is placed, that is, a single supporting plate 15 cannot support and place the cargo, as shown in fig. 1 and 2, at this time, the second supporting rod 13 needs to be folded from a vertical state to a horizontal state, the controller controls the motor and the electromagnetic plate 40 to be electrified again to work, as shown in step one, after the electromagnetic plate 40 is electrified, electromagnetic attraction is generated and the iron plate 39 is attracted and fixed, so that the toothed plate 35 is separated from the gear, the second supporting rod 13 is unlocked, the motor drives the first winding roll 8 to rotate reversely through the first rotating shaft 7, so that the first winding roll 8 pays off the pull rope 12, the second supporting rod 13 moves from the vertical state to the horizontal state under the action of gravity of each supporting plate 15, the form of the supporting plate 15 is known to be unchanged according to the motion trajectory of the parallel four-bar mechanism, and the horizontal state arranged from top to bottom is rotated to the same horizontal plane, when the second supporting rod 13 is in abutting-buckling contact with the supporting block 41 and the second touch switch 42, the second touch switch 42 transmits a touch signal of the second support rod 13 to the controller, the controller controls the motor and the electromagnetic plate 40 to be powered off and not work, the electromagnetic plate 40 loses electromagnetic suction force on the iron plate 39 after being powered off, so that the toothed plate 35 is meshed with the gear 34, the second support rod 13 is locked again, each bearing plate 15 is positioned on the same horizontal plane, the supporting area is increased, large-size goods can be placed, the using range is enlarged, the using flexibility and practicability of the whole goods shelf are improved, different placing forms of different goods can be stored by controlling each bearing mechanism, the safety protection mechanism can be used for increasing the safety protection performance of the bearing mechanism when the bearing mechanism supports the goods in a static state after the goods are placed, and the safety of the goods when the goods are placed is increased;
