While maintaining the original weight, the ratchet engagement area (with the same tooth count) has been increased by approximately 20%,thereby significantly boosting the load-bearing capacity of the planetary gears and ensuring more stable and reliable power transmission. Furthermore, the larger engagement area provides greater redundancy for the ratchet's engagement state, thereby significantly enhancing operational stability. This guiding design enables the pawl to engage with the gear more smoothly and precisely, resulting in faster engagement, significantly reduced backlash, and more direct power response.
