Wrench structure

A wrench structure comprising:

• a main body provided with a drive portion, a shank, a protruding block, and a handle;
• wherein:
• the shank is connected with the drive portion;
• the shank has two first faces formed on a top and a bottom thereof;
• the two first faces are parallel with each other;
• each of the two first faces has a planar shape;
• the shank has two second faces formed on two sides thereof;
• the two second faces are parallel with each other;
• each of the two second faces has a planar shape;
• the two second faces are perpendicular to the two first faces;
• the shank is arranged between the drive portion and the protruding block;
• the protruding block has two third faces formed on a top and a bottom thereof;
• each of the two third faces has an arcuate shape and includes a plurality of curved surfaces;
• the protruding block has two fourth faces formed on two sides thereof;
• each of the two fourth faces has an arcuate shape and includes a plurality of curved surfaces;
• the handle has two fifth faces formed on a top and a bottom thereof;
• each of the two fifth faces has an arcuate shape and includes a plurality of curved surfaces;
• the handle has two sixth faces formed on two sides thereof;
• each of the two sixth faces has an arcuate shape and includes a plurality of curved surfaces;
• the main body is further provided with a first connecting portion arranged between and connected with the protruding block and the handle;
• the first connecting portion has two seventh faces formed on a top and a bottom thereof;
• each of the two seventh faces has a concave arcuate shape and includes a plurality of curved surfaces;
• each of the two seventh faces is tangent to one of the two third faces and tangent to one of the two fifth faces;
• the first connecting portion has two eighth faces formed on two sides thereof;
• each of the two eighth faces has a concave arcuate shape and includes a plurality of curved surfaces;
• each of the two eighth faces is tangent to one of the two fourth faces;
• the main body is further provided with a second connecting portion arranged between and connected with the shank and the protruding block;
• the second connecting portion is tangent to the two first faces and tangent to the two second faces;
• the second connecting portion is tangent to the two third faces and tangent to the two fourth faces;
• the main body is sequentially provided with the drive portion, the shank, the second connecting portion, the protruding block, the first connecting portion, and the handle;
• the drive portion, the shank, the second connecting portion, the protruding block, the first connecting portion, and the handle are formed integrally;
• the shank, the protruding block, the first connecting portion, and the handle have different height and width defined therebetween;
• a first distance defined between the two first faces is a thickness of the shank;
• a second distance defined between the two second faces is a width of the shank;
• a third distance is a maximum distance defined between the two third faces;
• a fourth distance is a maximum distance defined between the two fourth faces;
• a fifth distance is a maximum distance defined between the two fifth faces;
• a sixth distance is a maximum distance defined between the two sixth faces;
• a seventh distance is a minimum distance defined between the two seventh faces;
• an eighth distance is a minimum distance defined between the two eighth faces;
• the handle has a middle position with a maximum thickness;
• the fifth distance is arranged close to the middle position of the handle;
• the handle has a distal position distant from the first connecting portion;
• the distal position of the handle has a minimum thickness;
• the handle has a proximate position close to the first connecting portion;
• the sixth distance is arranged close to the first connecting portion;
• the third distance is more than the fifth distance;
• the fifth distance is more than the seventh distance;
• the seventh distance is more than the first distance;
• the sixth distance is more than the fourth distance;
• the fourth distance is more than the second distance;
• and
• the second distance is more than the eighth distance.
