摘要： A positioning device for clipping apparatus includes a hollow body which has an open side on one side that holds a track portion and an anchor portion on another side. The body houses a sliding member having a clipping unit and a harness arm. The harness arm is connected to the track portion to form a displacement path of the sliding member. The clipping unit includes an upper clipping portion and a lower clipping portion. The upper clipping portion is driven by the sliding member to move close to the lower clipping portion. A linking means connects an elastic element to the anchor portion and the sliding member so that the elastic element can be stretched and retracted against the displacement path of the sliding member to provide a returning elastic force to the sliding member. Thereby the sliding member can be positioned rapidly on each displacement path.
