Due to gravity, the pendulum mass 33 swings back to the initial position. Therefore, the falling prevention crosspiece 12 of the scaffold and the groove-shaped guide rail rhythmically pushes the swinging block 33 upwards to collide with the swinging block 33 rhythmically downwards due to gravity, and the slow ascending action of the scaffold and the groove-shaped guide rail can be realized by alternative operation.

When falling, the groove-shaped guide rail and the anti-falling crosspiece 12 which move downwards rapidly drive the swing block 33 back to the horizontal position quickly, the swing block 33 is in the horizontal state, the front end of the swing block is clamped to tightly support the anti-falling crosspiece 12, and the rear end of the swing block is clamped to tightly support the limiting baffle 34, so that the scaffold can be prevented from falling.

The utility model discloses when the inserted lift scaffold normally descends, need will rotate back to prevent weighing down the support with this pendulum piece 33 artificial hand for the locating hole 333 of pendulum piece 33 corresponds with the spacing hole 322 of preventing weighing down the support, wears the bolt axle, fixes pendulum piece 33 in preventing weighing down the support, prevents its rotation, can realize the normal slow decline of inserted lift scaffold. In this state, the pendulum mass 33 does not project between the safety catch rails or does not intersect the connecting lines of the safety catch rails.
