Specifically, in the actual working process, the driving rod 21 of a single structure is not only in danger of being worn and broken after repeating hundreds of times of drawing motions, but also because the lengths of the driving stud guide hole 253 and the driven stud guide hole 251 are not usually very long, the driving rod 21 of a single structure is easy to cause the condition that the stroke of the driving element 1 is greater than the length of the driving stud guide hole 253, so that the stroke of the driving element 1 is not finished and the driving stud 22 is already pressed against the inner wall of the driving stud guide hole 253, and the driving rod 21 of a single structure is easy to be subjected to stress fracture. Therefore, the driving rod 21 is designed to have a three-stage structure, and the force applied to the driven element 213 is eliminated by the force transmission element 212, thereby protecting the driving rod 21. By adopting the preferred embodiment, the transmission rod 21 adopts a three-part structure, and the strength of the transmission rod 21 can be improved through the middle-section force transmission element 212, so that the stress of the transmission rod 21 is dispersed in three parts in the torque transmission process of the transmission rod 21, the transmission rod 21 is protected, and the service life in the long-term repeated operation process is prolonged.

As shown in fig. 5, in the transmission rod 21, the force transmission element 212 includes a force transmission piece 2121, a force transmission spring 2122 and two fixing pieces 2123, the two ends of the force transmission piece 2121 are respectively connected with the driving element 211 and the driven element 213, the two fixing pieces 2123 are fixed on the force transmission piece 2121 and connected with the two ends of the force transmission spring 2122, the force transmission spring 2122 extends along the axial direction of the transmission rod 21, a through hole 2124 is formed on the force transmission piece 2121, and the through hole 2124 is located between the two fixing pieces 2123; the driving element 211 comprises a driving plate 2111 and a locking post 2112, the driving plate 2111 sequentially passes through two fixing plates 2123 and penetrates through the force transmission spring 2122, the locking post 2112 is connected to the driving plate 2111 and positioned between the two fixing plates 2123, one end of the locking post 2112 extends into the through hole 2124, and the other end of the locking post 2112 is locked between two spirals of the force transmission spring 2122; the driving plate 2111 slides in the axial direction of the transmission rod 21, and the card 2112 slides in the through hole 2124. Specifically, in order to protect the driving rod 21 to the maximum and ensure smooth and uniform pulling movement of the driving rod 21, sliding movement of the driving post 22 and the driven post 23, and telescoping movement of the unlocking rod 3, the force transmission element 212 is designed to have both buffering and force transmission delaying functions. The driving plate 2111, the locking post 2112 and the force transmission spring 2122 form a buffer structure, when the driving element 1 applies force to the driving plate 2111 or when the driven element 213 applies force to the force transmission plate 2121, the locking post 2112 on the driving plate 2111 shifts the force transmission spring 2122, so that the spring between the locking post 2112 and one fixing plate 2123 is stretched, the spring between the locking post 2112 and the other fixing plate 2123 is contracted, the force transmission spring 2122 absorbs the force, no force is applied to the force transmission plate 2121 temporarily, and the buffer structure can effectively deal with the suddenly generated force when the driving element 1 is opened and closed, so that the suddenly generated force can be slowly, uniformly and smoothly transmitted to the next component. Meanwhile, the two fixing pieces 2123, the force transmission spring 2122, the locking post 2112, the through hole 2124 and the force transmission piece 2121 form a force transmission delaying structure, when the stretched and compressed spring absorbs the acting force, the stretched spring pulls the fixing piece 2123 and the compressed spring pushes the fixing piece 2123 open due to the restoring force of the spring, the acting force of the two parts of the spring on the two fixing pieces 2123 is the same, and finally the force transmission piece 2121 is pushed to move in one direction, and the movement of the force transmission piece 2121 is later than that of the driving piece 2111 or that of the driven element 213, so the structure is called a force transmission delaying structure. With the preferred embodiment, the buffering structure consisting of the force transmission spring 2122, the fixing plate 2123, the clip 2112 and the through hole 2124 is utilized to store the force applied by the driving element 1 to the driving element 211 by the force transmission spring 2122 and release the force to the driven element 213 by the restoring force of the force transmission spring 2122 during the operation of the driving element 1, so as to create a force transmission delay, and the protective transmission rod 21 can still ensure smooth force transmission when the driving element 1 is turned on or off or when the frequency changes suddenly.
