The insulating layer has an opening at the distal end to admit the layer coupler contact and to insulate the remainder of the second layer from the first layer.

Abstract: A tension exerciser with elastic limit function includes a weaving tape without stretching elasticity which is made of weaving materials and defined into a flexible elongated band pattern. The weaving tape includes a tape body, a fixed part and an operating end. The fixed part is provided with a positioning member. A handle is connected with the operating end, allowing the users to hold it for pulling. An elastic part is connected between the tape body and the operating end, so that elastic resistance occurs when holding the handle for pulling. An elastic limiter is connected between the tape body and the operating end. The elastic limiter enables the extension of the elastic part to be limited within the maximum load range, so as to prevent elasticity fatigue or even rupture of the elastic part of the tension exerciser, extend the service life and improve the operating safety.
