The utility model uses the positioning component to position the rotation angle of the assembly frame, thereby setting the guiding angles of the fixed guide ring and the movable guide ring, so as to facilitate guiding operations of the ventilation hose at different angles according to actual use requirements to meet different construction conditions. The spacing between the movable guide ring and the fixed guide ring is adjusted by the provided adjustment component, so that the movable guide ring and the fixed guide ring can be separated or combined for use according to actual needs during use, thereby enhancing the fixing and guiding effect of the ventilation hose.

It can only support, fix and guide a single model of hose, which is relatively single and cannot meet the guiding requirements of different models of hoses. Therefore, a tunnel ventilation hose guide device is proposed to solve the above problems. Utility Model Content
