Currently known torsion detecting resistors mainly use a variable resistor or a combination of a Hall sensing IC and a magnet, wherein the contact point position of the variable resistor is chord length of the torsion seat of the torque adjusting component. The distance changes to its resistance value, or the Hall induction IC induction magnet changes with the torque of the torsion force adjustment component of the torque adjustment component to generate a corresponding signal, and the controller changes according to the resistance value of the variable resistor or Hall. The signal generated by the sensing IC determines the amount of torque.
