The utility model relates to wire detection technical field, and disclose a kind of wire tensile strength detection device, the wire tensile strength detection device, including frame body, the top end surface of frame body is fixedly connected with controller, the side wall of frame body is fixedly connected with scale, the top end surface of frame body is provided with pullout component, the top of pullout component is provided with winding component.This wire tensile strength detection device, rotating
handle, it can be realized to the installation of wire body, relative to traditional pure manual winding, so that wire body arrangement is more neat and standard, improve winding consistency and
repeatability, it is favorable to
standardization operation, especially applicable to batch detection,
electrical performance consistency comparison etc. occasion, guide groove limits the movement trajectory of wire body, so that every circle wire body can be accurately arranged in predetermined position, avoid misplacement, overlapping etc. Problem, improve the accuracy of detection.
