8. The high-rise escape device for the fire fighting project according to claim 2, wherein a rubber layer is fixed to one side wall of the support plate (121), and anti-skid grooves are formed in the surface of the rubber layer.

9. A using method of a high-rise escape device for fire engineering is characterized by comprising the following steps:

the method comprises the following steps: clamping one fixing mechanism (100) with a window side wall body, enabling an auxiliary rod (120) and a fixing arm (130) at one end of a main rod (110) to be located on the outer side of the wall body, enabling the auxiliary rod (120) at the other end of the main rod (110) to be located on the inner side of the wall body, clamping the other fixing mechanism (100) with an adjacent window side wall body, enabling the two fixing mechanisms (100) to be symmetrically arranged in a mirror mode, and clamping the wall body between the two windows;

step two: the threaded rod (300) penetrates through the first opening groove (132) to enter the first round hole (131), the lantern ring (330) and the threaded sleeve (310) are located on the outer sides of the two fixing arms (130), the threaded rod (300) is pulled to enable the annular outer side wall of one end, close to the threaded sleeve (310), of the lantern ring (330) to be clamped with the corresponding first round hole (131), the threaded sleeve (310) is rotated to enable the threaded sleeve (310) to move towards the lantern ring (330) along the threaded rod (300), the outer side wall of the threaded sleeve (310) is clamped with the first round hole (131), and therefore the two fixing mechanisms (100) are squeezed and clamped to be fixed towards the middle, and the two fixing mechanisms (100) are prevented from deviating towards two sides;

step three: keeping the double-folding rod (400) unfolded, enabling two ends of the double-folding rod (400) to penetrate through the second opening groove (143) and to be placed into the second round hole (141), unfolding the double-folding rod (400), enabling the double-folding rod (400) to be bent into a V shape due to self weight, enabling annular joints (400a) at two ends of the double-folding rod (400) to be matched and sleeved with the corresponding second round hole (141), preventing the double-folding rod (400) from sliding out of the second opening groove (143), preventing the double-folding rod (400) from sliding out of the second round hole (141) through the annular dental plate (400b), and fixing the double-folding rod (400) between the two fixing mechanisms (100) and enabling the double-folding rod to be in a V shape;

step four: the safety backpack (210) is worn in front of the chest by a user through the braces (211), the O-shaped ring buckle (240) is buckled with the double folding rods (400), the manual slow descending device (230) is tightly held to move to the outer wall, the O-shaped ring buckle (240) slides to the bottom end of the V-shaped double folding rods (400) under the self-weight action of the user, then the manual slow descending device (230) is slowly loosened, the descending speed is controlled until the O-shaped ring buckle descends to the ground, so that the descending of the outer wall between two windows is realized, the heavy obstacles of a plurality of windows of a floor below are avoided, and the safety backpack is convenient to safely and quickly descend.
