The Hubsmith R&D team launched a new zero-time planar tooth ratchet for the ratchet body drive structure. During the 360-degree driving process, the zero-time planar tooth ratchet body has two parallel tooth surfaces (48 teeth) to achieve a zero-gap occlusal action at the same time. The complete occlusal and propulsion allows the driving performance to be more directly output. In addition, the zero-time planar tooth-type occlusal structure is more durable than traditional pawls.
