[0024] The vertical connection mechanism 10 includes an upper limit cylinder 101, a lower limit cylinder 102 is fixedly connected to the lower part of the upper limit cylinder 101, and through holes are provided on the inner sides of the upper limit cylinder 101 and the lower limit cylinder 102 to pass through them from top to bottom. Block grooves 103 are provided on the inner sides of the upper limit cylinder 101 and the lower limit cylinder 102, and a lever groove 104 is correspondingly provided in the block groove 103 to penetrate to the outer side of the upper limit cylinder 101 or the lower limit cylinder 102.

[0026] The working principle of the utility model is as follows: the bottom fixed bracket 1 realizes the moving function through four sets of universal wheels 2, which is convenient for quickly moving the safety frame at different construction positions. When the safety frame needs to be fixed at a certain position, by adjusting the support screw 4 under the T-shaped screw hole block 3, the support screw 4 is rotated by the hand crank 5 to make it extend downward and contact the ground, and at the same time, the support cushion contacts the ground to reduce the pressure on the ground, so as to achieve stable fixation. At this time, the universal wheel 2 is suspended and no longer subjected to force;

[0027] When the height of the safety frame needs to be increased, the vertical connection mechanism 10 can be used to connect the upper and lower parts. Four sets of vertical connection mechanisms 10 are placed between the two sets of support frames 6. The long lever 107 is pushed inward to retract the top block 105 into the block groove 103.

[0028] The fixing of the support platform 11 and the support inclined ladder 12 is achieved through the positioning and fixing mechanism 13. The positioning and fixing mechanism 13 on both sides of the support platform 11 or the support inclined ladder 12 is aligned with the fixing column 8 at the position that needs to be fixed, and downward pressure is applied to make the fixing column 8 fit into the groove above the arc-shaped top block 134. The arc-shaped design below the arc-shaped top block 134 can automatically fit the fixing column 8 to prevent the support platform 11 or the support inclined ladder 12 from shaking during use. When the support platform 11 or the support inclined ladder 12 needs to be disassembled, it is only necessary to push the paddle 136 to move the arc-shaped top block 134 upward and detach it from the fixing column 8, so that it can be easily disassembled.
