Abstract
The invention provides a torsion detecting assembly for combining a torsion acting assembly with adjustable torsion and a controller. The torsion detecting assembly comprises a rotated member and a rotation angle detecting member. The rotated member may rotate with the torsion seat of the torsion acting assembly within a certain angle range by using a rotating shaft as a fulcrum.
