The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.

As shown in fig. 1 to 8, an AGV traction device comprises a guide block 1, a traction support 3 and a gravity stop 6, wherein the guide block 1 is fixed on the bottom surface of the traction support 3, the guide block 1 is provided with at least two guide channels 10, a middle through hole 31 is arranged on the traction support 3, the middle through hole 31 is located in the guide channels 10, the gravity stop 1 is arranged in the middle through hole 31 and hinged to the traction support 3, the traction support 3 is horizontally arranged on the water surface, the gravity stop 1 is arranged in the middle through hole 31, and when the gravity stop 1 is in a free state, under the action of gravity, the gravity stop 1 is obliquely arranged in the guide channels 10.

The two gravity check blocks 1 are symmetrically arranged in front and back.

When the gravity stoppers 1 are in a free state, the two gravity stoppers 1 are inverted splayed.

The gravity block 1 is hinged with the traction support 3 through a pin 2.

The traction support 3 is provided with a locking groove 32, the top end of the gravity stop block 1 is connected with a locking bolt 5, the locking bolt 5 is provided with a locking nut 11, and when the gravity stop block 1 is in a locking state, the nut 11 and the locking bolt 5 are respectively clamped on two sides of the locking groove 32.
