Open end wrench structure

The creation department is related to the structure of the open-end wrench, in particular, the system of the open-end wrench structure is provided with a ratchet and a circular arc concave portion, and the ratchet and the circular arc concave portion are used for avoiding the wear of the screwing member when the screwing member is rotated. The angle.

As previously known, the conventional open-end wrench structure is shown in the seventh figure. The body 40 is provided with two opposite sides 41 and a concave curved surface 42 connecting the two opposite sides 41.

When the two opposite sides 41 of the body 40 rotate the screwing member 30, the screwing member 30 and the two opposite sides 41 are loosely fitted, so that the two pairs of edges 41 are clamped to the corner of the screwing member 30. At the end, when the screwing member 30 is rotated for a period of time, the screwing member 30 is easily worn to form a rounded end, thereby damaging the screwing member 30.

The patent case designed by our design team, such as application number 088220749, mainly consists of: one end of the open-end wrench is provided with four sides that can be clamped to the hexagonal screw or the hex nut, two of which are parallel, and the other two The sides are at an angle of one hundred and twenty degrees; the two sides of the wrench are connected with at least one ratchet and a circular arc recess, and three rounds are formed at the intersection of the four sides. The arc sag is used to increase the tightness during clamping and the pushing force during driving.

The open-end wrench 30 is provided with two arc-shaped recesses 34 and three arc-shaped recessed escaping slots 35. When the open-end wrench 30 rotates the screwing member 40, the corner 42 of the screwing member 40 can be in two circles. The arc recess 34 and the three arc recessed doffer slots 35 are in the range, and the wear angle 42 is avoided when the rotation is performed. Its advantages.

However, the patent is missing in that the open-end wrench 30 is structurally provided with a parallel side 31, a beveled edge 32, a ratchet 33, a circular arc recess 34, and a circular recessed doffer groove 35. The size of the open-end wrench 30 is determined by the size of the open-end wrench 30. Generally speaking, the open-end wrench 30 has more than forty specifications, including metric and inch sizes, and each type of open-end wrench 30 needs to be designed with five. The variable size constitutes an open-end wrench 30, and the five variable sizes are quite large, and it takes a considerable amount of time to design each of the open-end wrenches 30.

The conventional open end wrench has five variables and controls one. The size of the open-end wrench, the design of the open-end wrench structure is only four variable sizes to control the size of an open-end wrench to reduce design time and cost.

An open wrench structure comprising: a book The system has two opposite sides and two oblique sides, the two pairs of sides are parallel, and each pair of sides and each of the oblique sides and the two oblique sides are at an angle of one hundred and twenty degrees, and each pair At least one ratchet is disposed on the side, each of the ratchets is in the shape of a concave groove, and each of the opposite sides and each of the two sides of the oblique side is provided with a circular arc concave portion, and the circular arc concave portion is five. Each of the two circular arc recesses is provided with a carding edge, the ratchet is disposed within the range of the carding edge, the length of the carding edge is the first length, and the arcuate recess is a first radius; the two sides and two The hypotenuse system forms a hexagonal shape with a central axis at the center of the hexagon, each side of the hexagon is a side surface, the length of the side surface is a third length, and the first length is a 0.5-0.65 specification of the third length. between.

The system consists of two pairs of sides, two oblique sides, and multiple spines The four control sizes of the teeth and the five arc recesses constitute a one-size open-end wrench, and the less variable size reduces the time cost of designing the open-end wrench. The card edge of the body has a first length, the first A length is between 0.5 and 0.65 of the third length, so that the angular end of the screw has at least 1.75 gauge distance from the end of the card edge, and if the body rotates the screw, if there is a looser fit It shall not be damaged to the corner ends of the screw.

In order to enable the members of the Board and those skilled in the art to fully understand the effects of this creation, the structure and composition of the creation are described in conjunction with the drawings and drawings, but the following are only used to explain the implementation of this creation. For example, it is not intended to limit the invention in any way, and any modification made in the spirit of this creation should still fall within the scope of this creation.
