A torque-controlled rotational module is described. The torque-controlled rotational module has a fixing base, a rotational member, a spring member, and a torque adjusting ring. The fixing base further has a fixing wall and a cable hole therein for a cable to pass therethrough. The module further utilizes wear-resisting members configured on both sides of the rotational member, between the torque adjusting ring and the fixing base, to protect the torque adjusting ring and the fixing base from wear and tear. The fixing wall further utilizes a fixing indentation to couple to arresting protrusions of the wear-resisting members to avoid rotation of the wear-resisting members. The fixing base further utilizes a knob coupled to a slot of the rotational member to limit a rotational angle of the rotational member.
