[0025] The two rotating blocks 62 are symmetrically arranged along the central axis of the connecting block 3 , and a gap for the rotating blocks 62 to rotate is arranged between the two rotating blocks 62 , thereby ensuring that the two rotating blocks 62 do not affect each other when rotating.

[0026] The limiting clamping plate 65 is configured to be U-shaped, and the limiting clamping plate 65 is located on the displacement track of the plurality of clamping blocks 63 . The limiting clamping plate 65 can fix and limit the clamping blocks 63 .

[0027] According to the above structure, when transporting the sandbag board, the user holds the handle 66 and presses it hard, thereby driving the rotating block 62 to move in the direction of the first rotating wheel 4. The movement of the rotating block 62 will drive the multiple card blocks 63 away from the limiting card plate 65. The movement of the rotating block 62 will drive the rotating rod 61 to move and squeeze the spring 67. Then, the handle 66 is twisted.
