From the perspective shown in Fig. 2 , the driving mechanism 31 drives the force transfer rod 33 to rotate clockwise, the force transfer rod 33 pulls the first component 121 (i.e., the pull rope 123), and the first component 121 moves towards the direction of the coupler head 1 to pull the transition block 15 to rotate about the second pin shaft 11 so as to drive the locking block 10 to rotate away from the locking groove 2205. After the locking block 10 is completely disengaged from the locking groove 2205, the coupler is unlocked. Thereafter, the pull force of the driving mechanism 31 is completely converted by the force transfer rod 33 into the moment of pulling the first arm 21 to rotate clockwise, and the coupler is folded, as shown in Fig. 3 .
