Alternatively, the synchronizing connecting shaft 5 is connected to one end of the rotating shaft 41 through the shaft hole 55, the end matching the shape of the shaft hole 55, so that the rotating shaft 41 and the shaft hole 55 are relatively fixed in the axial direction of the rotating shaft. That is, the rotation shaft 55 cannot rotate with respect to the shaft hole 55. The shaft hole 55 may be provided as a non-circular hole, the end of the shaft 41 also being a matching non-circular portion.

For example, the shaft hole 55 may be a non-circular hole that fits into the second flat portion 416. When the rotating shaft 41 of one of the rotating shaft systems 4 rotates, the synchronous connecting shaft 5 is driven to rotate synchronously, and the synchronous connecting shaft 5 drives the rotating shaft 41 of the other rotating shaft system 4 to rotate synchronously. As long as one rotating shaft system 4 rotates, the other rotating shaft system 4 is driven to rotate, so that the synchronous rotation of the two connecting arms 3 is realized.

One end of the hinge body 471 is in interference fit with the rotating shaft system 4 through a pin 472, and the other end of the hinge body 471 is fixed with the connecting arm 3. When the connecting arm 3 is expanded, the hinge body 471 is driven to be expanded simultaneously. The hinge body 471 is in interference fit with the rotating shaft system 4, so that the outward-expanding damping can be increased, and the pulling hand feeling is improved.
