the plate body comprises a bottom plate, a top plate, a plurality of foot piers, and a plurality of main slots, wherein the bottom plate is disposed at a bottom of the plate body, the top plate is disposed over the bottom plate, wherein the bottom plate is arranged parallel to the top plate, wherein the top plate and the bottom plate are fixedly connected together through the plurality of foot piers, wherein the plurality of main slots are located between the bottom plate and the top plate and are blind on the side of the bottom plate and on the side of the top plate, wherein one end of the positioning structure is arranged in a respective main slot, another end of the positioning structure is operative extend outside of the respective main slot and is operative to extend out of a corresponding edge of the bottom plate and a corresponding edge of the top plate;
wherein the plurality of main slots are each defined by two adjacent foot piers spaced apart from each other, together with corresponding portions of the top and bottom plates, wherein the plurality of main slots each comprise an opening perpendicular to the top and bottom plates;
wherein the one end of the positioning structure is rotatably connected to the plate body, and the other end of the positioning structure is operative to rotate into the respective main slot;
wherein the positioning structure comprises an insert and a latch, wherein the insert comprises a first convex bar, a second convex bar fixedly and perpendicularly connected to the first convex bar, and a cylindrical first through hole defined in an end of the first convex bar far away from the second convex bar, wherein the first convex bar and the second convex bar are both cuboids; wherein the bottom plate comprises a first slot defined in a corresponding portion of the bottom plate surrounding each main slot and at an edge of the bottom plate adjacent to the opening of the corresponding main slot, wherein the latch is inserted through the first through hole into the first slot thus rotatably connecting the insert with the corresponding portion of the bottom plate.

2. The pallet according to claim 1 , wherein the latch is made of metal.

3. The pallet according to claim 1 , wherein the first slot and the latch are each cylindrical shaped.

4. The pallet according to claim 3 , wherein the first through hole has a greater diameter than a diameter of the latch.

5. The pallet according to claim 3 , wherein the first slot has a diameter equal to a diameter of the latch.

6. The pallet according to claim 3 , wherein the first slot has a diameter less than a diameter of the latch.

7. The pallet according to claim 1 , wherein the latch comprises a first latch portion and a second latch portion, wherein the first latch portion is perpendicularly connected to the second latch portion, and wherein the first latch portion is movably inserted into the first slot.

8. The pallet according to claim 1 , wherein the insert comprises a reinforcing structure, which is an elongated body, wherein one end of the reinforcing structure is fixedly connected to a side wall of the first convex bar, and wherein another end of the reinforcing structure is fixedly connected to a side wall of the second convex bar.

9. The pallet according to claim 1 , wherein the plate body is a cuboid, and there are two inserts, both arranged on a same rectangular side of the plate body and are symmetrical along a central vertical axis of the rectangular side of the plate body.

10. The pallet according to claim 1 , wherein a length of the second convex bar is greater than a spacing between a bottom surface of the top plate and a top surface of the bottom plate.

11. The pallet according to claim 1 , wherein the plate body is a cuboid, and the pallet comprises a second groove defined at an edge of a long side of the plate body, wherein the second groove comprises a top notch defined in an edge of a portion of the top plate corresponding to each main slot, and a bottom notch defined in an edge of a portion of the bottom plate corresponding to the main slot, wherein the second convex bar is located at an end of the insert opposite the end of insert rotatably connected to the bottom plate, wherein one surface of the second convex bar is parallel to a side surface of the long side of the plate body, a distance between the second groove and the first slot is equal to a length of the first convex bar, wherein the first convex bar is rotatable around the latch, and the second convex bar is fitted in the second groove when the insert is retracted back into the respective main slot.

12. The pallet according to claim 11 , wherein the second groove penetrates the plate body along a thickness of the plate body, and wherein a length of the second convex bar is equal to a thickness of the plate body.

13. The pallet according to claim 11 , wherein a depth of the second groove measured along a width of the plate body is equal to a width of the second convex bar, and wherein the second convex bar is operative to be fully embedded within the second groove.

14. A pallet, comprising:
a plate body configured to support stacked cargoes; and
a positioning structure configured to reduce a gap between adjacent plate bodies, wherein
the plate body comprises a bottom plate, a top plate, a plurality of foot piers, and a plurality of main slots, wherein the bottom plate is disposed at a bottom of the plate body, the top plate is disposed over the bottom plate, wherein the bottom plate is arranged parallel to the top plate, wherein the top plate and the bottom plate are fixedly connected together through the plurality of foot piers, wherein the plurality of main slots are located between the bottom plate and the top plate and are blind on the side of the bottom plate and on the side of the top plate, wherein one end of the positioning structure is arranged in a respective main slot, another end of the positioning structure is operative to extend outside of the respective main slot and is operative to extend out of a corresponding edge of the bottom plate and a corresponding edge of the top plate; wherein the plurality of main slots are each defined by two adjacent foot piers spaced apart from each other, together with corresponding portions of the top and bottom plates, wherein the plurality of main slots each comprise an opening perpendicular to the top and bottom plates;
wherein the positioning structure comprises an insert and a latch, wherein the insert comprises a first convex bar, a second convex bar fixedly and perpendicularly connected to the first convex bar, and a cylindrical first through hole defined in an end of the first convex bar far away from the second convex bar, wherein the first convex bar and the second convex bar are both cuboids; wherein the bottom plate comprises a first slot defined in a corresponding portion of the bottom plate surrounding each main slot and at an edge of the bottom plate adjacent to the opening of the corresponding main slot, wherein the latch is inserted through the first through hole into the first slot thus rotatably connecting the insert with the corresponding portion of the bottom plate;
