[0061] When the connecting shaft 623 rotates, the control gear 81 is driven to rotate. The engagement of the control gear 81 and the control rack 82 causes the connecting shaft 623 to move. At the same time, the first control sprocket 83, the second control sprocket 84 and the control chain 85 are driven to cause the mounting sliding block 612 to slide in the first sliding hole 6111 of the mounting rod 611.
