[0023] Two fixed rods 7 are provided with mounting cavities 701, and two rotating shafts 702 and two rotating shafts 705 are rotatably installed in the two mounting cavities 701, and the two rotating shafts 705 are symmetrically arranged on the two sides of the two rotating shafts 702, so that when the two rotating shafts 702 rotate, the two rotating shafts 705 rotate in opposite directions, and the take-up roller 707 is wound at the same time. The outer walls of the two rotating shafts 702 and the two rotating shafts 705 are fixedly provided with rotating gears 703 and rotating gears 706, and the two rotating gears 703 and the two rotating gears 706 are meshed with each other, so that when one rotating shaft 702 rotates, one rotating gear 703 drives the other rotating gear 703 to rotate in the opposite direction, and at the same time, the two rotating gears 703 drive the two rotating gears 706 to rotate in the opposite direction synchronously, so that the two take-up rollers 707 rotate in the opposite direction at the same time, and the two tension wires 709 are wound at the same time, so that the two ends of the two tension wires 709 are pulled to move towards each other in the fixed rod 7 at the same time, and the two take-up rollers 708 rotate in the opposite direction at the same time, and the two tension wires 710 are unwound, preventing the opposite movement of the two sliding blocks 715. Two rotating shafts one 702 and two rotating shafts two 705 are fixedly installed with two symmetrically arranged take-up rollers one 707 and take-up rollers two 708, so that the two rotating shafts one 702 and the two rotating shafts two 705 drive the two take-up rollers one 707 and the two take-up rollers two 708 to rotate, and the two take-up rollers one 707 and the two take-up rollers two 708 are arranged on both sides of the two rotating gears two 706.

[0024] The fixed rod 7 is fixedly installed with a servo motor 704 for driving the rotating shaft one 702 to rotate, and the two take-up rollers one 707 and the two take-up rollers two 708 are respectively wound with a tension line one 709 and a tension line two 710. The fixed rod 7 is slidably provided with two symmetrically arranged connecting blocks 716, and the two connecting blocks 716 are fixedly installed with two symmetrically arranged sliding blocks 715 at both ends.
