[0034] When the amplitude of the cable 21 is too large, the binding of the two control rings 33 to the cable 21 is weakened, and the cable 21 cannot be restored to stability in a short time, at this time, the control assembly 5 controls the plurality of sliding rods 45 to move close to the cable 21, the sliding rods 45 slide in the sliding grooves 44, until the extrusion blocks 46 at one end of the sliding rods 45 extrude the cable 21 from all directions, extruding and fixing the cable 21, further controlling the shaking of the cable 21, from originally only stabilizing the cable 21 by the control ring 33 to simultaneously suppressing the cable 21 from two places of the control ring 21 and the extrusion block 46, greatly enhancing the suppression effect of the device on the shaking of the cable 21;

[0035] When the amplitude of the cable 21 is too large, it will cause the cable 21 to rub against the corners of the control ring 33, and since the cable 21 is mostly twisted together by multiple steel wires, it is easy to cause the steel wires in the cable 21 to break and cause the wire explosion phenomenon. When the cable 21 explodes, the structural strength of the cable 21 is greatly reduced. When the cable 21 explodes, the broken steel wires will scratch the rubber detection ring 34, releasing the bright gas in the detection ring 34.
