Abstract

A grinding device includes a grinding assembly, a power output assembly, and a manipulation assembly. The grinding assembly includes a mounting member, a first grinding member, and a second grinding member cooperating with the first grinding member to implement grinding. The power output assembly includes a power element and a planetary gear mechanism. The planetary gear mechanism includes a sun gear, a planet gear, an internal gear ring, and a fixation frame. The sun gear is connected to the power element in a force-transfer manner. The planet gear is rotatably mounted at the fixation frame. The fixation frame includes an output member configured to output power. The manipulation assembly is connected to the mounting member. One of the first and second grinding members is connected to the output member in a force-transfer manner. Another one of the first and second grinding members is mounted at the manipulation assembly.
