Description

Wrench structure

The present invention relates to a wrench structure, and particularly refers to a wrench structure in which the handle is provided with a first recess, a protrusion and a rib, and the first recess, the protrusion and the rib enable the handle to It has the advantages of reducing weight, increasing rotational torque and toughness. The wrench structure has three structural advantages.

According to our previous knowledge, the commonly used wrench structure is a previous patent application filed by the applicant. The U.S. patent application number is 14/753037, which is the Taiwan patent application number: 103133837, and the certificate number: I520814 , Patent name: Open-end wrench structure.

However, the shortcomings of this conventional wrench structure are:

Please refer to the fifth figure of the patent publication. The handle 11 is provided with a groove. Although the groove can reduce the overall weight of the wrench structure and achieve the effect of saving material, the groove also makes the The wrench structure has the defect of reducing torque. If too much force is applied during rotation, the wrench structure will easily break from the middle of the groove, or the entire wrench structure may be bent from the middle of the groove. .

Another previous patent application filed by us is U.S. Patent Application No. 15/208625, which is Taiwan Patent Application No. 105115249, Certificate No. I579114, and the patent name is Wrench Structure. Please refer to Figures 1, 2 and 3 of the publication. The handle 11 is provided with a first protrusion 113. The first protrusion The block 113 protrudes from the upper and lower sides of the first surface 11; the handle 11 is provided with a first length 31, and the maximum length of the first protrusion 113 is the second length 32. The first length The ratio of 31 to the second length 32 is four to one to two to one. The thickness of the handle 11 is the first thickness 33. The minimum thickness of the first recess 112 is the second thickness 34. The thickness of the bump 113 is the third thickness 35.

However, the shortcomings of this patented wrench structure are:

The first bump 113 has the second length 32 and the third thickness 35. The first bump 113 allows the handle 11 to have a larger rotational torque and has structural advantages. However, the handle System 11 does not have a place where the hand can be supported. When the hand is held on the handle 13, the hand system is prone to slide naturally at the handle 11.

In view of the shortcomings of the wrench structure in the conventional patent cases mentioned above, the inventor has finally come up with a product with a wrench structure that can solve the shortcomings of the conventional wrench structure through many years of manufacturing experience in related industries.

In the conventional wrench structure, the entire wrench structure is bent from the middle of the groove, or the handle has no place for the hand to support. When the hand is held on the handle, the hand is easy to move naturally. slip. In the wrench structure of the present invention, the handle is provided with the first recess, the protrusion and the rib. The first recess, the protrusion and the rib enable the handle to reduce weight and increase rotation. Dynamic torque and toughness, this wrench structure has three structural advantages.

A wrench structure, which includes: a body, the body is provided with a handle, and two first surfaces are arranged on the upper and lower sides of the handle. Four first recesses are provided on the upper and lower sides. A convex block is provided in the center of the handle. Two second surfaces are provided on the upper and lower sides of the convex block. The second surfaces protrude from the second concave portions. The upper and lower sides of one side; the handle is provided with eight ribs, and each two ribs are provided on both sides of the first recess; the left and right sides of the handle are provided with Two first sides, two second sides are provided on both sides of the convex block, the two second sides protrude from the two first sides, and a first side is provided between the first side and the second side. A guide angle; one end of the handle is provided with a first rotating part, and the other end of the handle is provided with a second rotating part.

The first concave portion is provided on the upper and lower sides of the handle. The handle is provided with the convex block. The convex block is disposed between the two first concave portions. The first thickness is greater than the second concave portion. Thickness, the first concave portion can reduce the weight of the handle, the bump can increase the rotational torque during rotation, and the handle structure can achieve a balanced structure between the weight and the rotational torque. The handle is provided with eight ribs, and each two ribs are provided on both sides of the first recess. The eight ribs can have rotational torque. The first recess and the eight ribs can This makes the handle have rotational toughness in structure, and the rotational system is less likely to break. The first recess, the bump and the rib can reduce the weight of the handle and increase the rotational torque and toughness. The wrench structure has three structural advantages.
