Cleaning device and electrical power tool

A cleaning device, comprising:

• a first body having a drive device configured to output torque;
• a second body comprising a rotating portion, the drive device driving the rotating portion to rotate about a first axis;
• a cleaning component disposed on the rotating portion and rotating with the rotating portion;
• an angle locking device disposed between the first body and the second body and switchable between a locked state and an unlocked state;
• wherein the second body is rotatably connected to the first body, and a relative angle between the first body and the second body is adjustable;
• in the unlocked state, the angle locking device allows change of the relative angle between the first body and the second body;
• in the locked state, the angle locking device restricts change of the relative angle between the first body and the second body.

An electrical power tool, comprising:

• a first body having a drive device disposed configured to output torque;
• a second body comprising a rotating portion, the drive device driving the rotating portion to rotate about a first axis;
• a power transmission device having an input shaft connected to an output end of the drive device and an output shaft connected to the rotating portion;
• an operational component disposed on the rotating portion and rotating with the rotating portion;
• wherein a relative angle between the second body and the first body is adjustable, and the power transmission device is a non-coaxial transmission mechanism adapting to the change of the relative angle between the second body and the first body.
