[0021] The utility model is further explained below.

[0022] This utility model provides a truck tarpaulin clamping structure, mainly used to fix the truck tarpaulin 12. It includes a first clamping plate 21 and a second clamping plate 22, both with arc-shaped cross sections. The upper end of the first clamping plate 21 is provided with a first fixing plate 211 arranged along the length direction of the first clamping plate 21. The upper end of the second clamping plate 22 is provided with a second fixing plate 221 arranged along the length direction of the second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 are arranged opposite to each other to form a clamping cavity 25 for clamping the truck tarpaulin 12 on an arc-shaped support 11. A connecting member 23 for locking the first fixing plate 211 and the second fixing plate 221 is provided between the first fixing plate 211 and the second fixing plate 221.
