In another modification of the connecting member 40, as shown in fig. 2, the first lane 41a and the second lane 41b are linear. With reference to fig. 1, in the present embodiment, the cable 60 includes a first cable 61 and a second cable 62, the first cable 61 and the second cable 62 are respectively assembled in the first wire path 41a and the second wire path 41b, in order to prevent the first cable 61 and the second cable 62 from sliding relative to the connecting component 40 during pulling, one end of the first cable 61 has a pin 61a, one end of the second cable 62 has a pin 62a, the pin 61a and the pin 62a are respectively detachably fixed to the first wire path 41a and the second wire path 41b, and the other end of the first cable 61 and the other end of the second cable 62 respectively protrude from the first wire path 41a and the second wire path 41 b.

Compared with the winding groove of the cable 60 located at the inner side of the driving gear 10, the curvature of the wire path 41 in the present invention is smaller, so that the curvature of the cable 60 located in the wire path 41 is smaller, that is, the shape change is more gradual, and the stress concentration can be effectively prevented, thereby preventing the cable 60 from being broken.
In the present invention, the tooth grooves 42 are arranged along a segment of an arc or the entire circumference in the circumferential direction of the second rotating shaft 50. Referring to fig. 1, in this embodiment, the tooth sockets 42 are arranged along a section of arc, and when the connecting member 40 rotates under the pulling of an external force, a supportable rotation angle range of the tooth sockets 42 is limited, and is a central angle size corresponding to the tooth sockets 42 arranged along the arc; in another modification of the connection member 40, referring to fig. 3 and 4, the splines 42 are arranged along the entire circumference, and in this case, the splines 42 may support the connection member 40 to rotate at any angle.
