When 2 stress move down, compression elastic piece 5 can be made to deform upon；After the active force that guide rod 2 is subject to disappears, the elasticity of compression
Part 5 restores deformation, and guide rod 2 is driven to return to original state, to achieve the purpose that make guide rod 2 to reset.
It should be noted that above-mentioned compression elastic piece 5 is compressed spring.
In the present embodiment, pedestal is set as guide tube 1, guide tube 1 is provided with lower port, and guide rod 2 can be made to stretch out；Guide rod 2
It is arranged in guide tube 1；Guide rod 2 is divided into three parts from top to bottom, and the diameter of first part is more than the diameter of second part, but is less than
The inner diameter of guide tube 1；The diameter of second part is more than the diameter of Part III, and more than the diameter of 1 lower port of guide tube；The
The diameter of three parts is less than the diameter of 1 lower port of guide tube, and a part for Part III stretches out the lower port of guide tube 1；Compression
Elastic component 5 can cover on the second portion just, and one end of compression elastic piece 5 is connected to second part, and the other end is connected to
On the inner wall of guide tube 1, when 2 stress of guide rod moves down, the first part of guide rod 2 makes 5 compressive deformation of compression elastic piece, compression
Elastic component 5 can also play the role of stopping that the first part of guide rod 2 moves down, after the power that guide rod 2 is subject to disappears, compression elastic piece
5 restore deformation, make guide rod 2 by upward power, are moved upwards up to initial position.
If after compression elastic piece 5 damages, compression elastic piece 5 cannot play inhibition, guide rod to the first part of guide rod 2
2 second part can be stuck in the lower port of guide tube 1, prevent guide rod 2 from moving down excessively.
In another preferred embodiment of the present embodiment, cut-off switching device includes cut-off switch 9 and electric interlocking installation 8, is broken
Electric switch 9 is concatenated with electric interlocking installation 8, and electric interlocking installation 8 is fixedly connected on anti-rope falling device.
