Power tool

A power tool, comprising:

• an output shaft with a circumferential surface;
• a planet carrier with an inner side surface configured to be rotatably connected to the output shaft to drive the output shaft;
• there being a gap between the inner side surface of the planet carrier and the circumferential surface of the output shaft;
• and
• a buffer mechanism provided near the gap on at least one of the inner side surface of the planet carrier and the circumferential surface of the output shaft, the buffer mechanism being a single member and configured to buffer the impact force between the output shaft and the planet carrier when the output shaft slides relative to the planet carrier under the action of inertial force.

A power tool, comprising:

• a housing;
• a planet carrier;
• an outer support ring fixed on the housing;
• a cam disk provided in the outer support ring and coaxial with the outer support ring;
• a lock pin provided between the outer support ring and the cam disk;
• an output shaft fixedly connected to the cam disk;
• there being a gap between a circumferential surface of the output shaft and an inner side surface of the planet carrier;
• and
• a soft rubber provided on at least one of the inner side surface of the planet carrier and the circumferential surface of the output shaft near the gap;
• the soft rubber configured to buffer the impact force between the output shaft and the planet carrier when the output shaft slides relative to the planet carrier under the action of inertial force.
