Wherein, the driving element 1510 is a retractable rotary cylinder.

The telescopic shaft of the telescopic rotary cylinder can be firstly telescopic and then rotates, and the telescopic shaft of the telescopic rotary cylinder is completely disclosed in a rotatable telescopic cylinder disclosed in chinese patent publication CN206682074U, and therefore, the working principle of the telescopic rotary cylinder is not described herein again.

Wherein the lower end of the adjustment lever member 1520 is connected to the output shaft of the driving member 1510, so that the driving member 1510 can drive the adjustment lever member 1520 to move up, down, or rotate.

Since the distance from the top end of the adjusting member 1530 to the top end of the corresponding third mounting groove 1223 is gradually decreased from bottom to top, the driving member 1510 can drive the adjusting member 1530 to move upward by different distances, and thus different limiting members 1540 can be controlled to rotate.

For example, when there are three adjusting elements 1530, the first adjusting element, the second adjusting element and the third adjusting element are sequentially disposed on the adjusting rod element 1520 from bottom to top, the distance from the top end of the first adjusting element to the top end of the corresponding third mounting groove 1223 is 15cm, the distance from the top end of the second adjusting element to the top end of the corresponding third mounting groove 1223 is 10cm, and the distance from the top end of the third adjusting element to the top end of the corresponding third mounting groove 1223 is 5cm, so that when the adjusting rod element 1520 moves up by 5cm, the third adjusting element enters the corresponding third mounting groove 1223 and enters the inside of the corresponding limiting element 1540 to drive the corresponding limiting element 1540 to turn over; under the condition that the adjusting rod element 1520 moves up by 10cm, the second adjusting element enters the corresponding third mounting groove 1223 and enters the inside of the corresponding limiting element 1540 at this time, so as to drive the corresponding limiting element 1540 to overturn; under the condition that the adjusting component 1530 moves upwards by 15cm, the first adjusting component enters the corresponding third mounting groove 1223 at the moment so as to drive the corresponding limiting component 1540 to overturn.

Wherein the limiting member 1540 is capable of limiting the second screw element 1420 in case the adjusting member 1530 rotates the corresponding limiting member 1540, so as to prevent the second screw element 1420 from moving upwards and prevent the second screw element 1420 from rotating.

Specifically, in the case that the adjusting element 1530 drives the corresponding limiting element 1540 to flip, if the frame element 1410 drives the second screw element 1420 to move upward to be connected with the limiting element 1540, the frame element 1410 is driven by the first screw element 1340 to move upward, but the second screw element 1420 cannot move and rotate under the limit of the limiting element 1540, so that the gear element 1440 moves upward in rotation relative to the second screw element 1420, and then the gear element 1440 drives the carrying plate element 1450 to move toward the inside of the frame unit 1200 through the rack element 1460 to carry the cargo.

The first reset element 1550 is a reset spring, and is configured to drive the limiting element 1540 to reset when the adjusting element 1530 is separated from the limiting element 1540, so as to prevent the limiting element 1540 from obstructing the cargo unit 1400 from moving up and down.

in case that the second screw member 1420 is coupled with the restricting member 1540 in a fitting manner, the second screw member 1420 cannot move and rotate upward, and at this time, the gear member 1440 continues to move upward along with the frame member 1410, and since the gear member 1440 is screw-coupled with the second screw member 1420, the gear member 1440 can rotate upward along the second screw member 1420, and then the gear member 1440 protrudes the bearing plate member 1450 toward the inside of the frame unit 1200 through the rack member 1460 to receive the cargo;

in case that the cargo-pressing detecting lever member 1620 is moved to the inside of the frame unit 1200, if the detecting member 1640 detects that the cargo has completely moved to the upper end surface of the loading plate member 1450, the control member 1710 controls the second motor member 1310 to rotate so that the first screw member 1340 moves the supporting member 1410 downward;

in the case that the bottom end of the second screw element 1420 is limited in abutment with the ground, at this time, the bracket element 1410 continues to move downward, the gear element 1440 rotates to move downward, and then the gear element 1440 drives the bearing plate element 1450 to extend outward of the frame unit 1200 through the rack element 1460, so as to place the cargo on the four-way vehicle;
