Falling prevention structure for attached lift scaffold

A falling prevention system comprising a falling prevention structure adapted to be directly or indirectly affixed to a building object and a lift scaffold movable along the building object,

• wherein the lift scaffold comprises a lifting structure, a leveraged structure, a transition rod connected to a falling prevention pin in contact with an elastic restoring structure,
• wherein the leveraged structure has a control arm having a first end and a second end and an operating arm having a first end and a second end,
• wherein the second end of the control arm and the first end of the operating arm meet at a joint and form a fixed angle having the joint as a vertex of the fixed angle, wherein a hinge point is disposed in an interior of the fixed angle adjacent to the joint,
• wherein the first end of the control arm is attached to the lifting structure and the second end of the operating arm is attached to the transition rod,
• wherein, when the lifting structure exerts an upward force on the control arm, the leveraged structure rotates about the hinge point so that the operating arm retracts the transition rod to compress the elastic restoring structure and retracts the fall prevention pin, and
• when the lift structure does not exert the upward force on the control arm, the leverage structure returns to an initial position so as to extend the transition rod to release the elastic restoring structure to extend the falling prevention pin so that the falling prevention pin inserts into a clamping and hanging structure in the falling prevention structure, and
• wherein in the leveraged structure, the length of a section of the control arm between the hinge point and a point of connection with the lifting structure is smaller than the length of a section of the operating arm between the hinge point and a point of connection with the transition rod.
