Under the action of the gear 909 and the rotating rod 902, it is convenient to control the rotation and tilt of the supporting plate 903 and the protective connecting plate 904, so as to facilitate blocking the staff and prevent the staff from falling from a height. At the same time, under the action of the side plate 923, the push rod 926, and the push plate 925, the gas in the airbag 2 927 is passed into the airbag 1 905 to expand the airbag 1 905, so that the airbag 1 905 can cushion the fallen staff and prevent the staff from being injured. Through the protective rope 908, it is convenient to block the front side to increase the protective effect.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
