the double-thread guide rod 201 and the wire wheel 203 both rotate at different speeds to form differential speed, the claw 2022 clamps a first thread groove on the surface of the double-thread guide rod 201, and the wire wheel 203 linearly moves along the first thread groove in a first direction;

the wire wheel 203 moves to the tail end of the first thread groove, the clamping jaw 2022 rotates into the second thread groove, the wire wheel 203 linearly moves along the second thread groove in the second direction, and the first direction is opposite to the second direction.

After the wire wheel 203 makes a linear motion in the second direction, the method comprises the following steps:

the wire wheel 203 moves to the tail end of the second thread groove, the clamping jaw 2022 rotates into the first thread groove, and the wire wheel 203 moves linearly along the first thread groove in the first direction.

The above embodiments are intended to be illustrative, and should not be construed as limiting the scope of the invention, and the technical solutions, objects and effects of the present invention are described in full herein.

The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
