CHENLI independent research and development of new patented ratchet, with more advantages:

1 Camber, flanging design，add comfort

2 Reinforcement increase handle force

3 The slope chamber design of the lower card reduce the clearance between ratchet and lower card, increase the safety factor

4. the groove design reduce friction and allows the ratchet to operate more flexibly . thus reducing handle tension.

5. Double ratchet design, increase the safety factor

6. Flat bottom increase the contact surface with bound object, make the binding more stable

7. With patent number

8. Handle make operator feel more comfortable and use less force.
