Description

Special four-wheel positioning wrench

Technical Field

The utility model relates to the field of tools, in particular to a wrench for automobile maintenance.

Background

Four-wheel positioning requires adjustment of the mounting of the steering wheel, knuckle and front axle of the vehicle during maintenance to achieve the correct relative position.

Due to the structural design of the automobile, the nut which needs to be disassembled and assembled is often positioned behind some structural parts, or the space into which the wrench can extend is very narrow.

In the conventional four (or three) block wrench 1 ' shown in fig. 1, the bayonet 2 ' is open, that is, two parallel sides are provided on two sides of the bayonet 2 ': parallel sides 21 ', 22'.

In the working environment of four-wheel positioning, such a bayonet 2 'is often only able to grip the nut obliquely, or, although it is possible to grip the nut perpendicularly to its axis, the operator can only turn the wrench 1' in a very awkward position due to the space constraints at the bottom of the vehicle.

Therefore, the operator can not apply force when rotating the wrench 1 ', and the wrench 1 ' can easily slip off from the nut because the bayonet 2 ' is opened, thereby reducing the working efficiency and improving the operation risk.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. As used in this specification, the terms "upper," "lower," "inner," "outer," "bottom," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the utility model and simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the utility model. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 2 and 3:

the present invention has a wrench head 13 attached to the upper portion 11 of the wrench handle 10.

The wrench head 13 is a thin cylinder, six bayonets 2 are arranged on the periphery of the circle, each bayonet 2 is a regular hexagon with a notch 29 at the intersection of the bayonet 2 and the outer edge of the circle, and the bayonets 2 are communicated with the front surface and the rear surface of the wrench head 13.

That is, each bayonet 2 has two inner bottom edges (inner bottom edge 22, inner bottom edge 23) and two parallel edges (parallel edge 21, parallel edge 24), the two inner bottom edges (inner bottom edge 22, inner bottom edge 23) and the two parallel edges (parallel edge 21, parallel edge 24) are four hexagonal edges, the outer ends of the parallel edges are respectively provided with protrusions protruding toward the other parallel edge as the latch (parallel edge 21 protrudes from latch 27 toward parallel edge 24, parallel edge 24 protrudes from latch 28 toward parallel edge 21), so that latch 27, latch 28 are disposed oppositely, a gap is formed between latch 27 and latch 28 to form notch 29, and the inner edges of latch 27, latch 28 are the other two hexagonal edges (the inner edge of latch 27 is outer bottom edge 25, and the inner edge of latch 28 is outer bottom edge 26).
