When luggage is not placed on the bearing plate 4, the first operating rod 53 is in a state of inclining to the right, so that the carrying device is not convenient for people to push, the push rod 55 is arranged on one side of the first operating rod 53, which is far away from the bearing plate 4, so that the carrying device is convenient for people to push, and the carrying device is simple in structure and low in cost.

Specifically, two latch plates 132 are arranged on the stop lever 13, the two latch plates 132 are symmetrically arranged on two sides of one of the rubber sleeves 131, first through holes 133 are formed in the latch plates 132, the guide plate 14 is fixedly arranged on the horizontal rod 11 close to the latch plates 132, second through holes 142 are formed in the guide plate 14, a latch 141 is inserted into the second through holes 142, the two first through holes 133 and the second through holes 142 are coaxially arranged, and when the first connecting rod 21 rotates to contact with the rubber sleeves 131, the latch 141 is located on the right side of the first connecting rod 21.

When luggage is not placed on the bearing plate 4, the bearing plate 4 contacts the two horizontal rods 11, the latch 141 is only inserted into the second through hole 142, when the luggage is placed on the bearing plate 4, the first operating rod 53 rotates counterclockwise to drive the first connecting rod 21 to rotate counterclockwise around the first rotating shaft 2, so that the first connecting rod 21 contacts the rubber sleeve 131 on the stop lever 13, then the latch 141 is pushed to sequentially pass through the second through hole 142 and the first through holes 133 on the two latch plates 132, at this time, the latch 141 is positioned at the right side of the first connecting rod 21 to fix the first connecting rod 21, and when the carrying device is pushed to move forward, the first connecting rod 21 is prevented from rotating clockwise, the bearing plate 4 moves to the lower right, so that the luggage on the bearing plate 4 slides down, and unnecessary troubles are caused.
