Abstract

A position-fixing system includes a pole, a guiding member adjacent to the pole, and a movable member fitting around the pole. The pole is immovable relative to a window covering. The guiding member includes a principal axis parallel to an extension axis of the pole, and includes a retaining face substantially extending in the direction of the principal axis, but non-coplanar with it. The movable member corresponds to the retaining face. The movements of the movable member and the guiding member are related to that of a shaft of the window covering. When the window covering is being operated, the movable member is driven to rotate around the pole, and moves along the pole and the guiding member. Due to the retaining face, the movable member keeps contacting the pole to create a friction therebetween. Therefore, the position of a covering material of the window covering can be precisely fixed.
