Power tool

A power tool, comprising a body, a motor, a reducing gear set, an output shaft, a control circuit, and a setting module;

• wherein the body comprises a main casing and a handle connected to a side of a periphery of the main casing;
• the main casing has a head and a tail that are located along an axis in sequence;
• two opposite directions along the axis are respectively defined as a first direction and a second direction;
• the head is located on a side of the tail facing the first direction;
• another side of the tail facing the second direction has an end wall and a mounting wall;
• the mounting wall is closer to the handle than the end wall;
• wherein the handle comprises a handle casing and a battery module;
• an end of the handle casing has an end portion adapted to connect to the main casing;
• another end of the handle casing away from the end portion has an engaging portion;
• the battery module is detachably engaged with the engaging portion;
• a straight line that passes through the most protruding part of the handle along the second direction and a surface of the end wall and intersects the axis is defined as a collision boundary line;
• the mounting wall is located on a side of the collision boundary line facing the first direction;
• wherein the motor, the reducing gear set, and the output shaft are disposed in the main casing with the axis as a rotation center and are connected in sequence along the first direction;
• the output shaft has a driving head protruding out of the head;
• the control circuit is disposed in the body and is respectively and electrically connected to the motor and the battery module;
• the control circuit is adapted to control an operation of the motor;
• the setting module is disposed in the tail and is electrically connected to the control circuit;
• the setting module has a panel exposed outward on the mounting wall.
