Single-cylinder cone crusher convenient to disassemble

The invention discloses a single-cylinder cone crusher convenient to disassemble. The single-cylinder cone crusher comprises an upper rack, a fixed cone lining plate, a lower rack assembly, an interference ring and a tensioning ring, an interference ring is arranged below the upper rack, a tensioning ring is arranged below the interference ring, the interference ring and the tensioning ring are locked below the upper rack through a locking mechanism, and the fixed cone lining plate is dragged by the tensioning ring and is tensioned and fixed along the inner conical surface of the interference ring; and the inner conical surface of the lower rack assembly is in interference fit with the inner conical surface of the interference ring. By designing the interference ring, an original upper rack and an original lower rack are directly matched through a conical surface, an existing structure is that the interference ring and the upper rack are connected together through the bolt, the interference ring and the lower
