[0033] like Figure 3 As shown, in order to facilitate the smooth entry of the limiting block 16 into the limiting groove 14, the edge of the lower end surface of the limiting block 16 is provided with a chamfer.

[0034] like Figure 3 As shown, in this specific embodiment, the loading frame also includes at least two cross beams 12, and three cross beams are provided in this specific embodiment. The cross beams 12 are provided on the base plate 3. The length direction of the cross beams 12 is consistent with the width direction of the loading platform 2 and is a hollow structure.
