Anti-falling device, wall attaching device and attached type lifting scaffold

The invention discloses an anti-falling device, a wall attaching device and an attaching type lifting scaffold, the anti-falling device is installed at the end of a wall attaching support and comprises an anti-falling block, a trigger block, an anti-falling trigger and a gear, the anti-falling block is rotatably installed at the end of the wall attaching support, and the anti-falling end is in an initial state under the action of gravity; the trigger block and the anti-falling trigger rotate coaxially with the anti-falling block, and the gear is installed at the end of the anti-falling trigger and located on the lifting path of the track. When the lifting scaffold accidentally falls and rapidly descends, the rotating speed of the gear is larger than the reset rotating speed of the trigger block under the gravity effect of the balance weight check block, the balance weight check block is connected with a tooth groove of the gear in a clamped mode, the trigger block is locked with the anti-falling block through
