Ratchet wrench

A ratchet wrench, including:

• a main body, including a tool head and a grip, the tool head having a first receiving recess, a second receiving recess, and a third receiving recess which are arranged in sequence and communicate with each other;
• a ratchet head, rotatably received in the first receiving recess, the ratchet head including an annular toothed face and an operation portion;
• a toothed element, received in the second receiving recess and movable between a first position and a second position, the toothed element having a toothed portion at an end thereof near the first receiving recess, the toothed element having a switching recess at an end thereof near the third receiving recess, the toothed portion being engaged with the annular toothed face;
• a switching button, including a switching portion and a control portion, the control portion being rotatably inserted in the third receiving recess, the switching portion being located outside the main body, the switching portion being adapted for toggling to make the control portion rotate, the control portion being formed with two positioning recesses at an end thereof away from the toothed element, the control portion being formed with an insertion groove at an end thereof near the toothed element;
• a toggle element and a first elastic element, the toggle element being connected to the control portion via a first elastic element, an end of the toggle element away from the switching button extending into the switching recess;
• a positioning element and a second elastic element, the positioning element being received in the third receiving recess at an end of the third receiving recess away from the second receiving recess, the positioning element tending to move toward the switching button by the second elastic element, the positioning element selectively abutting against one of the two positioning recesses;
• a restriction element, the restriction element being substantially T-shaped to have a wider restriction portion and a narrower insertion portion, the insertion portion being inserted into the insertion groove, when the switching button is rotated, two sides of the restriction portion selectively abut against lateral walls of the main body between the second receiving recess and the third receiving recess so as to restrict a rotation range of the switching button;
• wherein the toggle element switches the toothed element between the first position and the second position by rotating the switching button.
