When the operator walks on the inclined surface of the roof of the building, the walking range is limited to the region on the side of the protection wire 122 between the two fixed pulleys 121, which is located on the lower side of the inclined surface of the roof of the building with respect to the protection wire 122.
The safety rope is added, so that the effect of enhancing the protection on the personal safety of an operator can be achieved; since the device is not safely used in an area range of the roof of the building higher than the height of the protection wire 122, limiting the operator's walking range to the lower side of the roof protection wire 122 can ensure the operator's operation safety.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
