A clamping seat 309 is fixedly connected to the bottom of the second protection net plate 307. A movable rod 308 is arranged on one side of the clamping seat 309. By setting the protection mechanism 3, when protection is needed, rotate the movable rod 308, and then rotate the second protection net plate 307. The second protection net plate 307 drives the clamping seat 309 to rotate, so that the clamping seat 309 is clamped with the movable rod 308, and the second protection net plate 307 can work stably. Then pull the first protection net plate 306 outward. During the pulling process of the first protection net plate 306, the semi-sphere 305 will be separated from the arc-shaped groove. After the semi-sphere 305 is clamped with the arc-shaped groove again, the first protection net plate 306 can work stably. Then the falling object can be blocked to avoid injuring the staff; a circular hole is opened at the bottom of the frame body 301, and the inner cavity of the circular hole is slidably connected to the vertical column 304. By setting the circular hole, the work of the vertical column 304 is stabilized, and the vertical column 304 is balanced and supported; an arc-shaped groove is opened at the bottom of the first protection net plate 306, and the arc-shaped groove is used in cooperation with the semi-sphere 305. By setting the arc-shaped groove, it is convenient to limit the first protection net plate 306 through the semi-sphere 305, so that the first protection net plate 306 works stably; chutes are opened on the front side and the rear side of the inner cavity of the frame body 301, and the inner cavity of the chute is slidably connected to the first protection net plate 306.
