[0031] Furthermore, two ends of the second rotating rod 15 are rotatably disposed on the first moving block 4 and the second moving block 5 , respectively, and the first rotating rod 6 is provided with a swing mechanism 16 for driving the second rotating rod 15 to swing synchronously.
[0032] Furthermore, the swing mechanism 16 includes a first synchronous wheel 16a disposed at the end of the first rotating rod 6 and a second synchronous wheel 16b disposed at the end of the second rotating rod 15, and a synchronous belt 17 is disposed between the first synchronous wheel 16a and the second synchronous wheel 16b.
