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. The rotation angle detecting member may detect a change in the rotation angle of the rotated member in order to generate a corresponding signal. The controller determines a corresponding torsion value according to the signal. The torsion detecting assembly achieves a function of detecting a micro torsion value change by detecting a rotation angle, and overcomes a technical problem that a conventional torsion detecting assembly cannot detect the micro torsion value change.
