Mechanism for preventing lattice apron from deviating for special-shaped pipe assembly of compact spinning device

The utility model relates to a lattice apron deviation preventing mechanism of a special-shaped pipe assembly of a compact spinning device. A bent edge and a plurality of supporting rod bases which extend out of a rod body and correspond to airflow guide grooves in a special-shaped pipe are arranged on a tension frame supporting rod, and each supporting rod base is provided with a protruding limiting guide block. The tension frame sliding seat comprises an integrated limiting seat, an adjusting seat with a sliding groove and an arc-shaped supporting part at the bottom, a cavity is formed between the limiting seat and the adjusting seat, flanges for preventing the lattice apron from deviating are arranged on the left side and the right side of the adjusting seat, guide-in faces for guiding the lattice apron are arranged on the inner sides of the flanges, and the included angle alpha between the flanges and the adjusting seat is smaller than 90 degrees; a supporting rod base on the tension frame supporting rod
