Workers can provide stable supporting force by stepping on the first support frame 101 and the second support frame 102, thereby preventing workers from stepping on the roof and causing damage to the roof, which is not conducive to the construction safety of workers. The sliding connection between the safety slide 109 and the safety slider 110 can realize the movement of the safety connecting rope 111, and the safety hook 112 and the safety connecting rope 111 can be used to connect the safety slide 109 and the safety slider 110. 11 can provide safety protection for workers and avoid the risk of workers falling. By turning the first rotating knob 116 to drive the first worm 117 to rotate, the first worm 117 is driven to rotate by utilizing the meshing connection between the first worm 117 and the first worm wheel 118, and under the limiting action of the spiral slide groove 119, the spiral slider 120 drives the fixed sliding rod 121 and the fixed anti-sliding block 122 to slide relatively inside the fixed sleeve 114, and the fixed anti-sliding block 122 is connected with the second telescopic sliding rod 123 through the fit, so as to realize the fixation of the second telescopic sliding rod 123. The first clamping blocks 124 on both sides of the second telescopic sliding rod 123 can clamp and fix the two ends of the roof, so as to adapt to roofs of different widths or depths.

[0027] Finally, by pressing the fixed tooth ring 129 and squeezing the fixed spring 130, when the fixed tooth ring 129 is separated from the clamping knob 128, the clamping knob 128 is turned to mobilize the meshing gear 126 to rotate, and through the meshing connection between the meshing gear 126 and the meshing rack 131, the meshing rack 131 drives the second clamping block 132 and the reinforced sliding plate 133 to move relative to each other, and the roof can be clamped and fixed by the second clamping block 132. At the same time, by utilizing the sliding connection between the reinforced sliding rod 136 and the reinforced sliding sleeve 137 inside the reinforced bracket 135, and under the elastic force of the reinforced spring 138, the clamping rotating rod 139 drives the reinforced support plate 140 to rotate, and the reinforced sliding plate 133 is supported by the reinforced support plate 140, thereby improving the support stability of the reinforced sliding plate 133.
