[0047] The implementation principle of a two-way clutch mechanism in the embodiment of the present application is as follows: the staff starts the driving motor 31 to rotate the driving worm 33, driving the driving worm wheel 32 to rotate clockwise, causing the driving wheel 34 to rotate clockwise, and the driven wheel 35 to rotate counterclockwise, driving the rotating cylinder 21 to rotate counterclockwise, causing the sun gear 212 to rotate counterclockwise. At this time, the first pawl 521 presses against the ratchet wheel 211, causing the planetary wheel 41 to rotate clockwise in place, driving the gear ring 42 to rotate clockwise, and causing the rotating cylinder 212 to rotate counterclockwise. The disk 24 rotates clockwise, the first flange 66 hits the first toggle column 64, causing the toggle plate 61 to rotate, the second toggle rod 63 hits the toggle block 523, causing the swing plate 52 to swing, the first pawl 521 to disengage from the ratchet 211, and the toggle plate 61 is affected by the tension spring 7 to quickly press the swing plate 52, causing the second pawl 522 to continuously abut against the side of the ratchet 211. At this time, the first pawl 521 abuts against the touch end of the micro switch 111, and the micro switch 111 sends a signal to the control system. The second pawl 522 is disengaged from the ratchet 211, and the toggle plate 61 is also affected by the tension spring 7, driving the first pawl 521 to continuously abut against the side of the ratchet 211, and at the same time, the second pawl 522 abuts against the touch end of the micro switch 111, and the micro switch 111 sends an electrical signal to the control system to stop the driving motor 31.
[0048] The staff realizes the bidirectional engagement of the first pawl 521 and the second pawl 522 with the ratchet 211 through the coordination of the sun gear 212, the rotating disk 24, the planetary gear set 4 and the toggle assembly 6.
