Thus, through the threaded connection of the first screw rod 47 and the first moving plate 48 and the cooperation of the first screw groove 49, the first moving plate 48 is driven to move upward along the first rotating frame plate 24, and with the cooperation of the scale bar 66, several fine ligaments can be woven into the anterior cruciate ligament with the required length specification at different height positions, which has good applicability, high flexibility, convenient operation, and the size of the woven ligament is detected through several bearing grooves 65. Secondly, rotate the second rotating handle 54 in the second notch 53 to drive the second screw rod 55 to rotate. Thus, through the threaded connection of the second screw rod 55 and the second moving plate 56 and the cooperation of the second screw groove 57, the second moving plate 56 is driven to move upward along the second rotating frame plate 30, and then, with the cooperation of the first movable tube 61 outside the first shaft rod 60, the woven ligament between the two slots 58 is tightened. During this process, the woven ligament will roll and contact with the second movable tube 64 under the cooperation of the second shaft rod 63, and the tension of the woven ligament can be adjusted without damaging it, which improves the stability of the tension adjustment process and ensures the safety of the woven ligament. At this time, the woven ligament is located between the two connecting rings 52, and the tension is detected in real time through the cooperation of the micro tension sensor 50 (model: LZ-LS3) and the pull rope 51. Finally, through the cooperation of the first fastening bolt 27 and the first fastening screw groove 28, the first connecting plate 26 is separated from the moving slider 23, and then the first rotating frame plate 24 is rotated to the horizontal state through the first hinge 25. Then, through the cooperation of the second fastening bolt 33 and the second fastening screw groove 35 and the connecting groove 34, the second connecting plate 32 is separated from the fixed plate 29, and then the second rotating frame plate 30 is rotated to the horizontal state through the second hinge 31. Immediately afterwards, the movable carrier plate 36 is rotated to the horizontal state through the cooperation of the third hinge 37, the third fastening bolt 38 and the third fastening screw groove 39. Then, the first connecting hole column 10 is separated from the second connecting hole column 12 through the first connecting plug rod 11 and the first screw ring 13. Then, the first connecting frame 3 and the second connecting frame 4 are brought into contact through the connecting hinge 5, the first magnetic strip 6 and the second magnetic strip 7, and the relative positions of the first connecting frame 3 and the second connecting frame 4 are fixed through the cooperation of the third connecting hole column 14, the fourth connecting hole column 16, the second connecting plug rod 15 and the second screw ring 17.Then, through the cooperation of the first fixed handle 8 and the second fixed handle 9, it can be transferred, replacing the traditional integrated weaving platform. It can be folded and stored when the weaving device is idle, reducing the occupied space of the weaving device and facilitating its handling and carrying to complete the operation.
