The working principle of the invention is as follows: in the using process, when the peripheral cable 2 is partially cut off, the rotation of the winding roller 31 on one side close to the cutting point inside the installation box 1 on two sides of the cutting point is not limited any more, so under the action of the resilience force of the clockwork 322 in the barrel 32, the winding roller 31 starts to rotate and suddenly and rapidly winds the cable 2 at the cutting end, and in the winding process, because the connecting seat 331 and the locking plate 332 fix the partial cable 2 on the winding roller 31 close to the cutting point on the surface of the winding roller 31 under the cooperation effect of the clamping groove 333, when the winding roller 31 winds the cable 2 at the cutting end part, even if the winding process of the cable 2 on the winding roller 31 is loosened due to the paying off of the connecting seat 331 and the locking plate 332 under the rotation effect of the clamping groove 333, the winding roller 31 can not generate obstruction to the winding process of the cable 2 at the cutting end part, so that the winding roller 31 can stably wind the cable 2 at the cutting end part, and the cable 2 can be accommodated in the accommodating cavity 7, and the alarm can be released to enable the alarm to push down the alarm wheel 513, so that a thief can move the alarm 511 can move to the alarm and push down and push the alarm wheel 511 can be released, and can move down, and can be moved to enable the thief.

In the process that the vertical block 511 moves downwards, one end of the lower linkage rod 521 is pulled and moves downwards synchronously along with the vertical block 511, because two ends of the lower linkage rod 521 are respectively connected with the clamping plate 522 and the vertical block 511 in a rotating manner, and under the limiting action of the movable groove, the clamping plate 522 can only do reciprocating motion in the horizontal direction, so that the lower linkage rod 521 can rotate integrally, the other end of the lower linkage rod can drive the clamping plate 522 to move in the horizontal direction, so that the clamping plate 522 can be withdrawn from the clamping groove 523 on the vertical plate 524, the vertical plate 524 is not supported any more by the clamping plate 522, at this time, under the action of self weight and the resilience force of the extrusion spring 525, the vertical plate 524 can move downwards, and in the process that the vertical plate 524 moves downwards, one end of the upper linkage rod 5261 can be driven to move downwards along with the vertical plate 524, because the two ends of the upper link rod 5261 are respectively rotatably connected to the vertical plate 524 and the translation plate 5262, and under the limiting action of the movement groove, the translation plate 5262 can only perform reciprocating movement in the horizontal direction, so that the translation plate 5262 can integrally rotate, and the other end of the translation plate 5262 can drive the translation plate 5262 to move towards the direction of the reduction gear 5265, and because the reduction gear 5264 is in contact connection with the surface of the reduction gear 5265 in the initial state, the amount of relative movement between the translation plate 5262 and the reduction gear 5264 is gradually increased along with the continuous movement of the translation plate 5262, so that the compression amount of the connecting spring 5263 is increased, the resilience force is increased, the friction resistance of the relative movement between the reduction gear 5264 and the reduction gear 5265 is gradually increased, and is maximized when the vertical plate 524 moves downwards to the limit position, so that the rotation of the winding roller 31 can be well slowed down and limited;

when the vertical plate 524 moves downwards, the movable rod 535 is driven to move downwards, the movable rod 535 drives the supporting spring 536 and the fixed tube 534 to move downwards, the fixed tube 534 moves downwards to drive the pressing plate 532 to move downwards, the pressing plate 532 moves downwards to be close to the cable 2, when the pressing plate 532 moves downwards to be in contact with the cable 2, the bottom of the fixed tube 534 does not move any more, at the moment, the movable rod 535 and the fixed tube 534 move relatively, the supporting spring 536 can be extruded, the contact pressure between the pressing plate 532 and the cable 2 is gradually increased, the moving speed of the cable 2 can be reduced, under the cooperation of the buffer 526, when the cable 2 is cut into the insulating protection box 531, the vertical plate 524 moves downwards to an extreme position, at the moment, the relative movement friction resistance between the speed reducing rod 5264 and the speed reducing wheel 5265 and the relative friction resistance between the pressing plate 532 and the cable 2 reach the maximum state, the continuous rolling of the cable 2 can be limited, the cut end of the cable 2 can be stored in the insulating protection box 531 for protection, and the electric shock can be effectively avoided, and the electric shock can be easily caused by the exposed maintenance operation of the installation personnel at the later stage of the installation box 1.
