[0031] The specific usage and function of this embodiment: after the staff stands in the protection support basket 5, the safety rope hook is fixed on the safety rope fixing ring 401. At this time, the safety rope hook will squeeze the limit sliding frame 6, so that the limit sliding frame 6 drives the extrusion inclined block 602 to move downward. When the extrusion inclined block 602 moves, it will push the compressed inclined block 701 to move, thereby driving the circular limit shaft 7 to retract and leave the limit circular hole 101. At this time, the manual hoist can be operated to make the sliding support frame 4 drive the protection support basket 5 to rise along the support base frame 1. After the use of the operating platform is over, the protection support basket 5 is moved back to its original position and the safety rope hook is removed. At this time, the limit sliding frame 6 is automatically reset under the action of the first elastic member 601, and the circular limit shaft 7 is automatically reset under the action of the second elastic member 702 and is clamped in the corresponding limit circular hole 101 to position the sliding support frame 4.
