Adjustable Wrench

An adjustable wrench comprising:

• a first body and a second body;
• wherein:
• the first body is provided with a first mounting portion;
• the first mounting portion has a side provided with a second mounting portion;
• the second mounting portion is connected to the first mounting portion;
• the second mounting portion is a transverse open slot having two parallel faces;
• the second mounting portion has a side provided with a third mounting portion having a planar shape;
• the third mounting portion is perpendicular to the second mounting portion or almost perpendicular to the second mounting portion;
• the first body is provided with a first operation end;
• the first operation end is provided with a first rotation portion having a planar shape or a toothed shape;
• the first mounting portion includes two first faces, two second faces, a third face, two fourth faces, and two end portions;
• each of the two first faces has a planar shape;
• each of the two second faces has a planar shape;
• the third face has an arcuate shape;
• each of the two second faces is between one of the two first faces and the third face;
• the third face connects the two second faces;
• the third face is tangent to the two second faces;
• each of the two fourth faces is an arc;
• each of the two first faces and each of the two second faces are between the third face and one of the two fourth faces;
• each of the two end portions is provided on a corner of one of the two first faces;
• each of the two end portions is located at an intersection of one of the two first faces and one of the two fourth faces;
• the two first faces, the two second faces, the two fourth faces, and the two end portions are arranged symmetrically relative to the third face;
• each of the two first faces is parallel with or almost parallel with the third mounting portion;
• each of the two second faces is parallel with or almost parallel with the second mounting portion;
• in a two-dimensional view, the third face constructs a first circle having an axis and a first radius;
• each of the two fourth faces coincides with the first circle;
• the axis is a center of each of the two fourth faces;
• each of the two fourth faces and the third face have the first circle, the axis, and the first radius;
• the first circle passes the two end portions;
• a first distance is defined between each of the two end portions and the axis;
• each of the two second faces has a length defining a second distance;
• a first angle is defined between each of the two first faces and one of the two second faces;
• a third distance is defined between each of the two end portions and the third mounting portion;
• a fourth distance is defined between the two parallel faces of the second mounting portion;
• the first distance is equal to the second distance or the first distance is more than the second distance;
• the fourth distance is less than two times of the first radius and more than the first radius;
• the third distance has the maximum value;
• the third distance is more than the fourth distance;
• the fourth distance is more than the first radius;
• the first radius is more than the first distance;
• the second body is provided with a fourth mounting portion mounted on the first mounting portion;
• the fourth mounting portion includes two fifth faces, two sixth faces, and two seventh faces;
• the two fifth faces align with the two first faces;
• the two sixth faces align with the two second faces;
• the two seventh faces align with the third face;
• the fourth mounting portion has a side provided with a fifth mounting portion mounted on the second mounting portion;
• the fifth mounting portion has a side provided with a sixth mounting portion mounted on the third mounting portion;
• the sixth mounting portion has a planar shape;
• the second body is provided with a second operation end;
• the second operation end is provided with a second rotation portion aligning with the first rotation portion;
• the fourth mounting portion has a side provided with an engaging portion exposed from the slot;
• the engaging portion is disposed between the two seventh faces;
• the engaging portion has a helical toothed shape or is a linear toothed rack;
• the fourth mounting portion is mounted on the first mounting portion, the fifth mounting portion is mounted on the second mounting portion, and the sixth mounting portion is mounted on the third mounting portion, so that the second body is slidable on the first mounting portion, the second mounting portion, and the third mounting portion of the first body, and the second rotation portion is movable relative to the first rotation portion.
