When the cable jumps the groove: in this state, the cable will have the trend of pushing up the anti-drop wheel 4, because the anti-drop wheel 4 is coaxial with the pressing shaft 3, one end of the pressing shaft 3 is limited on the hanger 1 by the ball body, and cannot move upwards, the other end of the pressing shaft 3 is fixed by the transmission guide rod 10, and the transmission guide rod 10 cannot move upwards because the locking column 16 is clamped in the tooth slot 100, so that the phenomenon of jumping of the cable is avoided.

When the traction force disappears to lead the cable to fall back: the traction force of the cable disappears, so that the cable moves downwards due to self gravity, the anti-drop wheel 4 is pressed on the cable, after the cable is too fast, the rotation of the pressing shaft 3 is also accelerated, the anti-drop stop block 11 in the pressing shaft 3 is pressed by the centrifugal force to push out the anti-drop stop lever 2 under the magnetic repulsive force between the lifting magnetic block 12 and the adjusting magnetic block 13, after the anti-drop stop block 11 moves between the anti-drop stop lever 2 and the adjusting magnetic block 13, the magnetic shielding between the lifting magnetic block 12 and the adjusting magnetic block 13 is realized, the anti-drop stop lever 2 cannot be retracted through the addition of the anti-drop stop block 11, after the anti-drop stop lever 2 passes through the arc-shaped convex part 101, the arc-shaped convex part 101 limits the movement of the pressing shaft 3, meanwhile, the pressing shaft 3 is pressed downwards, and the pressing force between the pressing shaft 3 and the anti-drop wheel 4 is further enhanced;

meanwhile, as the limiting stop block 11 shields the magnetic repulsion between the adjusting magnetic block 13 and the lifting magnetic block 12, the attraction of the adjusted magnetic block 13 to the limiting stop block 11 can enable the adjusting magnetic block 13 to move towards the limiting stop block 11 until the adjusting magnetic block 13 is opposite to the magnetic channel 300, at this time:

1. if the cable is fixed by pressing the anti-falling wheel 4 and the guide wheel 5, the cable is locked;

2. if the pressed cable between the anti-drop wheel 4 and the guide wheel 5 is not locked, at the moment, the anti-drop wheel 4 is limited and cannot move, a sliding phenomenon is generated between the cable and the side wall of the anti-drop wheel 4, the cable drives the anti-slip ring 400 to synchronously rotate, the rotation of the anti-slip ring 400 can enable the magnetic channel 300 to be communicated through the magnetic channel 401, so that the magnetic surfaces between the adjusting magnetic block 13 and the pressurizing magnetic block 18 are opposite, the pressurizing magnetic block 18 is forced to approach to the anti-slip ring 400 through the magnetic attraction phenomenon generated between the adjusting magnetic block 13 and the pressurizing magnetic block 18, the jacking base 7 moves towards the anti-drop wheel 4 through the pulling of the transmission guide rod 10, at the moment, the jacking base 7 moves towards the transmission guide rod 10, the pressurizing block 701 is forced to move downwards through the pressing cylinder 15, the pressing cylinder 15 further pulls the transmission guide rod 10 to move downwards, the pressing force between the pressing shafts 3 and the anti-drop wheel 4 is increased, the constraint strength of the cable is increased, at the same time, the pressing cylinder 15 is limited in the tooth socket 100 through the magnetic attraction phenomenon, and the locking column 16 is limited in the direction of the anti-drop wheel 400, so that the pressing block 15 can be pressed downwards;

when the cable lock is released later, the traction mechanism holds the cable again, so that the anti-release stop lever 2 is separated from the arc-shaped convex part 101, the fall limiting stop block 11 is restored under the action of the elasticity of the fall limiting spring 110, the magnetic repulsion between the lifting magnetic block 12 and the adjusting magnetic block 13 forces the adjusting magnetic block 13 to move downwards, and the jacking base 7 moves upwards along the positioning seat 700 under the action of the elasticity of the return spring 170, so that the state is restored to the state when the pressure is not increased.
