Description

[Technical field]

[0001] The present invention relates to a wrench structure, and in particular to a wrench structure having a first recess on both the top and bottom of a handle, the handle having a protrusion having a second recess on the protrusion, the first recess reducing the weight of the handle and the second recess also reducing the weight of the handle, the protrusion increasing the rotational torque when rotated, the handle being structured to balance the weight and rotational torque, and the handle allowing the wrench body to be easily gripped in the hand and rotated. [Background technology]

[0002] Conventional wrench structures include, for example, Patent Documents 1 and 2, which were previously filed by the applicant of the present invention.

[0003] In the "wrench structure" of Patent Document 1 and Patent Document 2, as shown in Figs. 1 to 3, the handle 11 has a first protrusion 113. The first protrusion 113 protrudes from both the upper and lower sides of the first surface 111. The handle 11 has a first length 31. The maximum length of the first protrusion 113 is a second length 32. The ratio of the first length 31 to the second length 32 is 4:1 to 2:1. The thickness of the handle 11 is a first thickness 33. The minimum thickness of the first recess 112 is a second thickness 34. The thickness of the first protrusion 113 is a third thickness 35.

[0004] However, Patent Documents 1 and 2 have the following drawbacks. First protrusion 113 has second length 32 and third thickness 35. First protrusion 113 provides handle 11 with a structural advantage of being able to obtain a large rotational torque, but handle 11 does not have a portion for supporting the hand, and so the hand tends to slip when gripping handle 13 with the hand.

[0005] The inventors of the present invention have conducted extensive research in light of the shortcomings of the above-mentioned conventional wrench structures, and as a result have completed a wrench structure that can improve upon the problems of the conventional technology.

The symbols or patterns may be printed and formed in a flat shape.

[0034] The wrench structure of the present invention has the following advantages (1) to (10). (1) First recesses 112 are provided on both the top and bottom of handle 11. Handle 11 has protrusions 113. Second recesses 115 are provided in protrusions 113. First recesses 112 allow the weight of handle 11 to be reduced. Second recesses 115 also allow the weight of handle 11 to be reduced. Protrusions 113 increase the rotational torque during rotation. Therefore, handle 11 has a structure that allows a balance between weight and rotational torque. (2) The handle 11 has eight rib portions 116. Two rib portions 116 are provided on both sides of the first recess 112. The eight rib portions 116 have rotational torque. The first recess 112 and the eight rib portions 116 give the structure of the handle 11 toughness, making it less likely to break even when the handle 11 is rotated. (3) The handle 11 has a first thickness 41, a second thickness 42, a third thickness 43, and a fourth thickness 44. The handle 11 has different thicknesses at different positions. Since the handle 11 is designed with a structure having different thicknesses, the weight is reduced and the rotational torque and toughness when the handle 11 is rotated are high. (4) To summarize the above points (1) to (3), the first recess 112, the protrusion 113, the second recess 115, and the rib portion 116 have three structural advantages: the weight of the handle 11 is reduced and the rotational torque and toughness are increased. (5) When an operator holds the wrench structure in his / her hand and rotates it, the thumb of the operator can rest against first chamfer 119, and by placing the thumb against first chamfer 119, the wrench structure can be easily rotated. (6) When an operator holds the wrench structure in his / her hand and rotates it, since protrusion 113 has first thickness 41, which is greater than third thickness 43, the operator can place the thumb on second connection portion 1141 and third connection portion 1151, and can rotate the wrench structure by placing the thumbs on both ends of protrusion 113. (7) When holding and rotating the wrench structure with one's hand, the thumb of the hand can be placed against the second connecting portion 1141 and the third connecting portion 1151, or against the first chamfer 119, so that the main body 10 can be easily rotated. (8) As can be seen from the advantages (5) to (7) described above, when holding main body 10 with the hand, depending on an individual's operating habits, the thumb can be placed on protrusion 113, on second connecting portion 1141 and third connecting portion 1151, or on first chamfer 119, so there are many places on main body 10 where the hand can be placed. (9) Since handle 11 has first thickness 41, second thickness 42, third thickness 43, fourth thickness 44, first width 33, second width 34, third width 35, fourth width 36, fifth width 37, sixth width 38 and seventh width 39, the structure of handle 11 has many advantages, such as reduced weight, increased rotational torque and toughness, and the ability to rotate body 10 by gripping it with one's hand. (10) Handle 11 has first surface 111, first recess 112, protrusion 113, second surface 114, second recess 115, rib portion 116, first side surface 117 and second side surface 118, and by designing a variety of different structures into handle 11, handle 11 can be given a three-dimensional appearance.
