The operation is simple and the automobile wiring harness can be folded to different angles.

[0035] A specific application of this embodiment is: the staff first installs the device to the specified position, and then places the automobile wiring harness to the left side of the friction ring 104, and starts the motor 107 at the same time. The motor 107 starts to drive the worm 108 to rotate, and the rotation of the worm 108 drives the worm wheel 110 to rotate.

Because the automobile wiring harness has contacted the guide plate 202, the back of the automobile wiring harness will be transported when the friction ring 104 rotates, so that it slides along the angle of the right side of the guide plate 202 to achieve the bending of the automobile wiring harness. At the same time, it can be adjusted according to the size of the automobile wiring harness. When the automobile wiring harness needs to be folded at different angles, the push plate 206 is slid toward the front, and the push plate 206 is moved to drive the card block 205 to move, and the spring 207 is squeezed. When the card block 205 slides toward the front, it will be disengaged from the card rod 203, canceling the restriction on the card rod 203, and then the guide plate 202 is pushed downward to drive the card rod 203 to disengage from the fixed block 201, and then the guide plate 202 is removed for replacement, which is simple to operate.
