Problems solved by technology

[0002] In daily life, bolts are the most commonly used locking and connecting methods, and the shape of the bolt head can roughly tell the force that the bolt can withstand. Generally, it is turned with a cross or a straight screwdriver Round head bolts have a small bearing capacity and are commonly used in household electrical appliances; hexagonal flat head or concave hole bolts have a large bearing capacity and are commonly used in various industrial products such as machinery, automobiles and motorcycles. They have a wide range of applications and are suitable for There are also many hand tools, such as open-end wrenches, socket wrenches, fixed wrenches, hexagonal wrenches, and plum blossom hexagonal wrenches. Diversification, however, nowadays only a single-sized bolt with a certain specification of hand tools can be turned without damaging the service life of the bolt
[0003] The most common troubles encountered by ordinary operators when turning the rotating bolt are that the hand tool is not correct, and the second is that the size does not match. Therefore, it is often necessary to understand the tool type first and choose different sizes many times before finding a hand tool that meets the specifications. in vain inconvenience and distress

Embodiment Construction

[0019] Such as figure 1 , 2, the present invention provides the bolts that can be pulled by multi-type hand tools. The open-end wrench 2 clamps and occludes and pulls, and the shortest distance between the arc tangents formed by the two long side arcs 111, that is, the position perpendicular to the direction of the two short side straight sides 110, can provide a smaller open-end wrench 2 'Clamping and occlusal pulling, and by means of different collocations of the tangent line distances of the elliptical gardens, it can have a variety of different specifications of the opposite side distances, as shown in Figure 2 A, B, C, D four different The specifications and dimensions of the size are used to provide open-end wrenches 2, 2' of different sizes, that is, the same bolt head 11 can be used with at least four open-end wrenches of different specifications, so as to improve its flexibility and facilitate the operator. Use hand tools.

[0020] The above is that the present inve...

Abstract

A screw bolt able to be turned by the manual tools different in size and type features that the peripheral edge of its bolt head is composed of two short straight edges and two long arc edges for adapting the different open spanner, and a recess made on the top surface of said bolt head has an edge consisting of 6 arc edges and 6 straight edges, which are alternative, for adapting to hexagon spanner and quincunx hexagon spanner.

Description

technical field [0001] The invention relates to a bolt, which refers to a bolt that can be turned and rotated by hand tools of different sizes and types, and provides convenience for operators to select hand tools during operation.
