[0029] Working principle:
[0030] The power pull wire is passed through the space between the rotating rod 5 and the fixed shaft 17, and then guided to the space between the rotating rod 5 and the abutting pipe 12. The rotating disc 7 is rotated to drive the driving bevel gear 14 to rotate, and the rotation of the driving bevel gear 14 is transmitted to the driven bevel gear 13 to drive it to rotate synchronously. The screw rod 4 fixedly connected to the top of the driven bevel gear 13 is also rotated. Since the screw rod 4 is threadedly connected to the moving seat 1 and penetrates the moving seat 1, the rotation of the screw rod 4 drives the moving seat 1 to move linearly. The moving seat 1 is adjusted to the appropriate initial height position, the rotating rod 5 is kept clamped and fixed to the pull wire, the distance between the two half seats of the distance adjusting seat 10 is adjusted by rotating the adjusting bolt 11, the abutting pipe 12 abuts against the power pull wire, the handle 6 is held and rotated, the abutting pipe 12 installed on the rotating rod 5 is rotated with the rotating rod 5, and the power pull wire is gradually bent. In the process of rotating the handle 6, the pawl 9 works with the ratchet wheel 8. When the handle 6 is forwardly rotated to drive the rotating rod 5 to rotate, the pawl 9 will jump over the teeth of the ratchet wheel 8 in sequence, so that the rotating rod 5 can be smoothly rotated. When the handle 6 has a reverse rotation trend due to external force or other factors, the pawl 9 will be clamped to the ratchet wheel 8 to prevent the handle 6 and the rotating rod 5 from being reversely rotated, so that the position of the rotating rod 5 and the abutting pipe 12 in the bending process can be kept, the power pull wire can keep the bent angle, and the pull wire can be prevented from rebounding due to accidental reverse rotation. After staying for a while, the power pull wire can be shaped. The rotating disc 7 is reversely rotated to drive the screw rod 4 to reversely rotate, the power pull wire is gradually loosened, the adjusting bolt 11 is reversely rotated to increase the distance between the two half seats of the distance adjusting seat 10, and the power pull wire can be taken out.
[0031] In the whole bending process, since the moving seat 1 can only move along the axial direction of the guide rod 3, the moving seat 1 is prevented from being deviated, shaken or rotated during the rotation of the rotating rod 5, and the accuracy of the bending angle of the power pull wire is kept.
