Preferably, prevent falling fixedly on the piece mounting bracket and be provided with first round pin axle, it is equipped with prevents falling the piece to rotate the cover on the first round pin axle, prevent falling the piece and cooperate with a plurality of stull of preventing weighing down respectively, through preventing falling the piece and a plurality of cooperation of preventing weighing down between the stull, can play the effect of preventing falling to scaffold.

Preferably, the anti-falling block is provided with bearing teeth and shifting teeth, the bearing teeth are located above the shifting teeth, falling impact load can be transmitted to the wall-attached support through the bearing teeth arranged on the anti-falling block, and the shifting teeth arranged on the anti-falling block can play a role in monitoring the motion state of the anti-falling cross brace.

Preferably, the anti-falling block mounting frame is fixedly connected with a reset tension spring, the other end of the reset tension spring is fixedly connected to the top of the anti-falling block, and the anti-falling block can be ensured to be in a specific position in a free state by arranging the reset tension spring.

Has the advantages that: the anti-falling cross brace is driven to move up and down along with the scaffold through normal lifting of the scaffold and push the shifting teeth and the bearing teeth to rotate up and down, so that the anti-falling block rotates clockwise and anticlockwise, then the bearing teeth and the shifting teeth rotate out of the motion influence range of the anti-falling cross brace, in addition, the anti-falling block can be pushed or pulled to rotate back to a free balance position through the elastic characteristic of the reset tension spring, and at the moment, the bearing teeth and the shifting teeth are positioned outside the influence range of the anti-falling cross brace and cannot block lifting of the scaffold;

then when the scaffold falls, the anti-falling block is impacted and rotated by the falling-preventing cross braces, the falling-preventing block and the falling-preventing cross braces are separated to form a balance position, however, due to the fact that the falling linear speed of the scaffold is increased rapidly, when the falling speed is higher than the falling-preventing block impact point and the linear speed is recovered, the shifting teeth are not separated from the next-stage anti-falling cross braces, the bearing teeth are impacted by the previous-stage anti-falling cross braces, the bearing teeth are clamped between the two anti-falling cross braces, and the scaffold is prevented from continuously falling. Impact load finally transmits to attaching the wall support through preventing weighing down the piece, preventing weighing down a piece mounting bracket, preventing weighing down baffle etc. and on transmitting the building again, not only can play the effect of preventing weighing down to scaffold frame through preventing weighing down the piece and the cooperation between a plurality of anti-falling crossbearers, can also carry out the pressure release conduction with the power when scaffold frame weighs down, has improved the device's life for the device is not fragile.

The anti-falling device is ingenious in design, simple in structure and good in anti-falling effect, protects the safety of the scaffold at all times, and improves the safety of the attached lifting scaffold.
