1. Mechanical transmission, compact structure and reliable performance.

2. It is not easy to slip, and thin-walled materials can also be bent.

3. Mechanically adjust the wheelbase. Without the labor of a hand wheel.

4. The transmission of the machine is stable, and only need to adjust and press to obtain circular, arc or spiral shapes with different curvatures.
