Transmission network chain applied to high-temperature working environment

The utility model relates to a transmission network chain applied to high temperature working environment, which is formed by mutually hinging a plurality of network chain units, the structure of each network chain unit comprises a clamping part (21), connecting parts (22), a hooking part (23), a supporting part (24) and an anti-drop part (25), the clamping part (21) is positioned in the center, the two ends of the clamping part (21) are respectively connected with one connecting part (22), the connecting parts (22) and the clamping part (21) are arranged in a bending way, and the hooking part (23) is positioned on the supporting part (24). The other end of each connecting part (22) is bent and connected with a hooking part (23), the hooking part (23) on one side is connected with a supporting part (24), and the supporting parts (24) are arranged in parallel; and the hooking part (23) on the other side is connected with the anti-falling part (25). The fixing device has the advantages of being firm in fixation
