At the same time, the rotating drum 9 The rotation of the rod 6 drives the rotating plates 25 at both ends thereof to rotate synchronously. During the rotation of the rotating plates 25, the slider 27 is driven to slide downward in the slide groove 26 of the moving bar 24, and then the moving bar 24 is pushed away from the fixed bar 22 of the mounting plate 33, driving the folded folding frame 23 to unfold. The folding frame 23, the fixed bar 22 and the moving bar 24 are used as a whole to play a role of safety protection on both sides of the elevator. The movement of the moving bar 24 also drives the first handrail board 28 and the second handrail board 29 to rotate to a horizontal state, and the folded ... The first armrest plate 28 and the second armrest plate 29 are used as armrests as a whole, and finally the motor 30 can be started to drive the screw rod 31 to rotate, and the guide rail seat 32 can be used to move up and down on the rotating screw rod 31 to realize the automatic lifting function of the elevator. When the elevator is not in use, the hydraulic cylinder 8 can be started to drive the extension plate 3 to move down and insert it into the lifting frame 1, and respectively drive the standing plate 5, the support plate 18 and the moving bar 24 to reset, so that the elevator can be folded, which greatly reduces the occupied space of the elevator, is convenient for storage, has a simple structure and practical functions.
