The utility model provides a torsion angle turning device. The torsion angle turning device comprises a base assembly and a balance rod fixed to the base assembly. The base assembly comprises a shell,a gear, a worm, a first clamping plate and a second clamping plate, wherein the gear and the worm are horizontally installed in the shell, the first clamping plate covers the shell and covers the gear and the worm, and the second clamping plate is fixed to the outer side of the first clamping plate in an overlapped mode. Wherein the balance rod is fixed on the gear, the balance wheel rotates forwards to drive the gear to rotate forwards, the gear and the worm are meshed with each other and generate torsion moment through the transmission ratio between the gear and the worm, and the torsion moment enables the balance rod to rotate reversely when not subjected to external force; the first clamping plate and the second clamping plate are used for being fixed to the installation position andare riveted to the gear th
