[0008] Furthermore, a hanging rope or a first hook is sewn on the top of the protective cover, and a connecting portion for connecting and fixing with the hanging rope or the first hook is provided on a side of the fixing block away from the adjusting block.

[0009] Furthermore, the protective cover is provided with a hardened area at the bottom of the wall opening.

[0010] Furthermore, the protective cover is provided with an adhesive area around the wall opening.

[0011] Furthermore, the clamps arranged horizontally at the bottom of the wall opening are lower clamps, and the bottom of the protective cover is flipped and fitted onto the outer wall surface of the wall to form a lower fitting surface. The lower clamps are close to one side of the wall, and the lower fitting surface is located between the wall and the fixed block.

[0012] Furthermore, the clamps arranged in a horizontal row at the top of the wall opening are upper clamping props, and the top of the protective cover is connected to the upper clamping props.

[0013] Furthermore, the protective cover is a plastic film or a protective net.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are:

[0015] The anti-falling device for dismantling old doors and windows of high-rise buildings cooperates with a protective cover and a clamp.
