Tortoise shell net

The utility model relates to a tortoise shell net, which is composed of trapezoidal waveform steel belts which are buckled. The utility model is characterized in that mud claws of the utility model are in special shapes. The utility model has the advantages that the utility model can fix inner lining materials of hexagonal meshes of the utility model; the anchoring capacity for the lining materials of the utility model is obviously enhanced; because connecting holes corresponding to mud claws on two waist positions of the trapezoidal wave-shaped steel belts enlarge the connecting area between two adjacent hexagonal meshes of the utility model, the connecting performance of the lining materials is effectively enhanced; the utility model can fully control the easy peeling and fall phenomenon of a heat insulation layer to increase the combining hardness of the lining materials; the service life of the utility model is enhanced; the occurrence of production accidents is reduced.
