The utility model discloses a cable limiting suspension device. A suspension body includes a first plane end and a second plane end which are opposite to each other; a blind hole is formed in the first plane end; a connecting rod is fixed on the second plane end; the connecting rod is hinged with one end of an arc-shaped rod; the arc-shaped rod is configured in a manner that the movement track of the arc-shaped rod passes through the second plane end when the arc-shaped rod rotates around a hinging joint; two supporting rods are fixed on the second plane end; the supporting rods are located above the connecting rod; the arc-shaped rod is located between the two supporting rods; a magnet is slidingly arranged in the blind hole; one end of a sliding rod is connected with the magnet; the other end of sliding rod passes through the bottom of the blind hole and passes through a space between the two supporting rods to be hinged with one end of a moving rod; and the other end of the moving rod is hinged with the arc-shaped rod. With the cable limiting suspension device of the utility model adopted, a fixing function and a limiting function can be realized simultaneously. When the cable limiting suspension device is fixed, there is no need to drill holes in a steel frame. When the cable limiting suspension device is used, fixation and limitation can be realized simultaneously, and therefore, the cable limiting suspension device is convenient to use.
