When the rotating rod 702 is in contact with the moving block 601, the rotating rod 702 can drive the moving block 601 to rotate by a corresponding angle through the rotation angle of the rotating rod 702, so that the installation position of the tension spring can be accurately positioned by adjusting the different rotation angles during the installation of the tension spring, and the loosening phenomenon during the installation process can be avoided.

[0026] The working principle of the embodiment is that when the tension spring is installed and fixed, the overall bending phenomenon is prone to occur, so that the elastic effect of the tension spring after bending is weakened, so that the tension spring cannot achieve the expected effect after installation, and the mechanism processes it, at this time, the moving block 601 is pushed to move towards the bending plate 5, when the moving block 601 slides in the adjusting plate 701 by a certain distance, the tail of the moving block 601 is perpendicular to the rotating rod 702, and at this time, the moving block 601 pushes the movable rod 708 to move, when the movable rod 708 moves, the pulling rod 706 is driven to rotate, when the pulling rod 706 rotates, the second spring 707 is driven to rotate, when the pulling rod 706 rotates, the two circular wheels 709 on the two sides are synchronously rotated, when the circular wheel 709 rotates, the insertion rod 705 is driven to rotate, when the insertion rod 705 rotates, it is inserted into the rotating rod 702, so as to pass through the inner wall of the moving block 601, at this time, the moving block 601 can be rotated downward, so as to ensure that when the position of the tension spring needs to be moved, the tension spring can be ensured not to bend when moving, so as to complete the work.

[0027] Embodiment three: please refer to Figures 8-10 On the basis of the embodiment one and the embodiment two, the technical scheme of the application is provided: further comprising a fixing mechanism 8, the fixing mechanism 8 comprises a second sliding block 801, the second sliding block 801 is slidably connected with the inner wall of the bending plate 4 on the side close to the bending plate 4, a rotating plate 802 is rotatably connected with the inner wall of the second sliding block 801 through a second rotating shaft, the position of one side of the tension spring is fixed by the rotating plate 802, so as to ensure that only the other side needs to be pulled when the tension spring is stretched, which can effectively avoid the overstretching of the tension spring due to uneven stress when the tension spring is installed at both ends, and prevent the phenomenon that one end of the tension spring cannot rebound, the rotating plate 802 is used for limiting the position of the tension spring, a positioning rod 803 is arranged on the rotating plate 802, the positioning rod 803 is fixedly connected with the rotating plate 802 on the side close to the rotating plate 802, a horizontal plate 804 is rotatably connected with the top of the positioning rod 803 through a third rotating shaft, an arc-shaped hole 807 is formed in the side of the horizontal plate 804 close to the gap of the rotating plate 802, the horizontal plate 804 is used for limiting the fixed distance of the tension spring, two groups of hook plates 806 are arranged on the hole wall of the arc-shaped hole 807, by arranging the hook plates 806, when one side of the tension spring rotates, the hook plates 806 push the other side of the tension spring to rotate by the same angle synchronously, which can ensure that the tension spring maintains a straight line state during angle rotation, avoiding the problem that the rebounding force is reduced due to bending, the two groups of hook plates 806 are slidably connected with the hole wall of the arc-shaped hole 807, the two groups of hook plates 806 are fixedly connected with the third spring 805 on the side close to the horizontal plate 804, the two groups of third springs 805 are fixedly connected with the horizontal plate 804 on the side away from the hook plates 806, and the hook plates 806 are used for pulling the tension spring to move by different angles.

[0028] The working principle of this embodiment is as follows: During the installation of the tension spring, when it is necessary to move both sides of the tension spring for position adjustment, the pull ropes on both sides are often out of sync. This out-of-sync force may cause plastic deformation of the tension spring, thereby shortening its service life. To address this problem, this mechanism achieves precise synchronization through innovative design. The specific workflow is as follows: During installation, the operator first fixes the tension spring to the rotating plate 802. When the other side of the tension spring is displaced due to the angle rotation, it will push the hook plate 806 to rotate upward. During the upward rotation of the hook plate 806, a tensile force is applied to the third spring 805. At this time, the stretched third spring 805 will generate a reverse pull force acting on the hook plate 806. Driven by this reverse pull force, the hook plate 806 begins to rotate downward. When the hook plate 806 rotates downward, it will pull the pull ring to move synchronously on the rotating plate 802, thereby ensuring that this side of the tension spring always remains parallel to the other side. Through the dynamic adjustment mechanism of this mechanism, the problem of unbalanced force during tension spring installation is effectively solved, thus completing the work.
