Anti-falling system of attached lifting protection platform

The utility model relates to the field of building construction, in particular to an anti-falling system of an attached lifting protection platform, which comprises a support, a trigger swing block, an anti-falling swing block and a guide rail, the anti-falling swing block comprises a light part and a heavy part which are integrally arranged, and the gravity center of the anti-falling swing blockis located on the heavy part. The light parts of the trigger swing block and the anti-falling swing block are rotationally connected with the support through the same rotating shaft; a lower baffle and an anti-falling baffle which are used for limiting the rotation range of the anti-falling swing block relative to the support to be 0-90 degrees are arranged in the support. The guide rail has the beneficial effects that the support can support and connect the guide rail with the wall surface in a static state; when the guide rail ascends or descends normally, the anti-falling swing block and the triggering swing block
