[0026] like Figure 4 As shown, a shock absorbing component 3 is provided on the protective frame body 1, and the shock absorbing component 3 includes a plurality of first telescopic rods 301 arranged on one side of the protective frame body 1, and a first spring 302 is sleeved on the first telescopic rod 301, and the mounting frame 4 is connected to the telescopic end of the first telescopic rod 301; specifically, the first telescopic rod 301 and the first spring 302 can play a shock absorbing role on the protective frame. When the protective frame is performing high-altitude operations, even if the ground is calm, it is still difficult to avoid shaking at a high altitude, and the shock absorbing component 3 can also play a good shock absorbing role to a certain extent.

[0027] like Figure 5 As shown, a plurality of rollers 6 are slidably arranged in the installation frame 4 , and a clearance groove 505 adapted to the rollers 6 is provided on the vacuum suction cup 503 .

[0028] like Figure 3 As shown, an adjusting member 7 for adjusting the position of the roller 6 is arranged in the installation frame 4 .

[0029] like Figure 2 and 3As shown, the adjusting member 7 includes a plurality of second telescopic rods 703 arranged on one side of the interior of the mounting frame 4 and a threaded sleeve 701 rotatably arranged inside the mounting frame 4, the threaded sleeve 701 is internally threadedly connected with a threaded rod 702, one end of the second telescopic rod 703 and the threaded rod 702 is connected with a mounting plate 708, and the roller 6 is arranged on one side of the mounting plate 708; specifically, under the action of the adjusting member 7, the position of the roller 6 can be adjusted, so that when performing aerial work, the roller 6 can be moved out from the inside of the vacuum suction cup 503 so that it can contact the wall, and the roller 6 can reduce the resistance to its movement. At the same time, when performing aerial work, the protective frame is raised and lowered in close contact with the wall, which can reduce the degree of its shaking, making it safer to use.

[0030] like Figure 2 and 3 As shown, a worm gear 704 is sleeved on the threaded sleeve 701, and two fixing plates 705 are arranged inside the installation frame 4, and a motor 706 is arranged on one side of one of the fixing plates 705, and a worm 707 meshing with the worm gear 704 is connected to the main shaft end of the motor 706; specifically, the motor 706 can drive the threaded sleeve 701 to rotate when it is working, and the rotation of the threaded sleeve 701 can drive the threaded rod 702 to move out from the inside of the threaded sleeve 701, so that the position of the roller 6 can be moved, and when lifting, the roller 6 can be moved out from the inside of the vacuum suction cup 503, so that it can contact the wall, thereby improving the stability of the lifting of the protective frame, and when encountering a sudden strong wind, the roller 6 can be moved into the interior of the installation frame 4, and the vacuum generator 501 works to make the vacuum suction cup 503 negative pressure, so that the protective frame can be adsorbed and fixed on the wall, so as to prevent it from swaying with the wind and causing a large degree of collision between the protective frame and the wall.

[0031] In summary: the first telescopic rod 301 and the first spring 302 provided during high-altitude operations can play a shock-absorbing role for the protective frame. When the protective frame is performing high-altitude operations, even if the ground is calm, it is still difficult to avoid shaking at high altitudes. The provided shock-absorbing component 3 can also play a good shock-absorbing role to a certain extent. At the same time, under the action of the adjusting component 7, the position of the roller 6 can be adjusted. Therefore, when performing high-altitude operations, the roller 6 can be moved out from the inside of the vacuum suction cup 503 so that it can contact the wall. The roller 6 can reduce the resistance to its movement. At the same time, when the protective frame is performing high-altitude operations, Lifting and lowering in close contact with the wall can reduce the degree of shaking, making it safer to use. When encountering strong wind volume, the roller 6 is moved into the interior of the installation frame 4, and the provided adsorption limiting member 5 can adsorb the protective frame to the wall under the action of negative pressure to prevent it from constantly shaking and colliding with the wall under the action of wind force. It can not only protect the staff on the protective frame, but also prevent the protective frame from constantly drifting in the wind and causing collisions with the wall and the protective frame. Therefore, it is safer to use and can also protect the staff on the protective frame in the event of sudden strong winds.
