Keep the dirt and other impurities away from the ratchet mechanism.
It is easy for ashes or other impurities to get into the ratchet mechanism.
The double pawl design is able to distribute the bearing weight in order to increase the efficiency of the transmission.
Traditional ratchets are made with single pawl design, which implies that the pawl needs to bear full force of the transmission.
Integral molding design shorten the distance of the open end in order to increase the strength of the structure of the machine, and prevent the area from deforming. Compare to traditional design, the service life of the new design is three times higher than the old model, and the open end can never deform.
The open end of the traditional design normally deformed after time. Due to the materials and internal stress during the heat treatment process, the issue of the drive part cannot operate on the original position, which leads to the dysfunction of the ratchet.
