Embodiment 1

[0043] Such as figure 2Shown is the adjustable wrench of the present invention, including a distance sleeve 2, a long torque rod 1, an adjustment track 4 and a sliding block 3, wherein the distance sleeve 2 is a tubular cylinder; the long torque rod 1 is set One end of the distance sleeve 2 is fixedly fitted with it, and the axis of the long torque rod 1 is approximately perpendicular to the axis of the distance sleeve 2. In this embodiment, the long torque rod 1 is set to pass through the The penetration hole 22 on the cylinder wall of the distance sleeve 2 is fixedly fitted, that is, a radial through hole is formed on the axial side wall of the distance sleeve 2, and the moment long rod 1 passes through the distance sleeve 2 The through hole 22, so as to realize the axial fixation of the long moment rod 1 in the distance sleeve 2, but not limit its radial movement; the adjustment track 4 is fixedly arranged on the end surface of the other end of the distance sleeve 2 , the...

Embodiment 2

[0046] Such as Figure 7 Shown is the adjustable wrench of the present invention, including a distance sleeve 2, the distance sleeve 2 is tubular; a long torque rod 1, the long torque rod 1 is arranged at one end of the distance sleeve 2 and fixedly matched with it In this embodiment, a square column is formed at the end where the distance sleeve 2 cooperates with the moment long rod 1, and a square hole is formed on the moment long rod 1 to be radially fixedly matched with the square column; The axis of the moment rod 1 is approximately perpendicular to the axis of the distance sleeve 2;

[0047] Two adjustment rails 4, the adjustment rail 4 is fixedly arranged on the end face of the other end of the distance sleeve 2, the adjustment rail 4 is welded on the distance sleeve 2 in this embodiment, the adjustment rail 4 The extension line of the central axis of the long side intersects the axis extension line of the distance sleeve 2; in this embodiment, the adjustment track 4 i...

Abstract

The invention relates to an adjustable wrench and a nut for the same. The adjustable wrench comprises a distance sleeve, a long torque rod and two or more adjusting tracks, wherein the adjusting tracks are fixedly arranged on the end surface of the other end of the distance sleeve; an extending line of a central axis of each adjusting track along the direction of a long side is intersected with an axial extending line of the distance sleeve; a sliding block is arranged on each adjusting track, is a strip square block and can be in sliding fit with each adjusting track; and the locking block can be locked at any position of each adjusting track by the locking mechanism. A nonstandard bolt and nut fastening tool in the prior art is high in manufacturing cost, is time and labor consuming in finding and carrying and is inconvenient to use, so the invention provides the adjustable wrench which is suitable for fastening a nonstandard bolt in a counter bore and is convenient to carry and use and is low in cost.

Description

technical field [0001] The invention relates to a wrench and a nut, in particular to an adjustable wrench and a nut suitable for the adjustable wrench. Background technique [0002] A wrench is a tool used to turn bolts, nuts, and other objects that are difficult to turn by hand. [0003] The wrenches on the market are generally designed to apply standard nuts and standard bolts. Non-standard parts are replaced by ordinary wrenches because of their small usage and uncertain size and shape. See figure 1 As shown, although the wrench of the prior art can also carry out size adjustment during use, it is not only very laborious in use, but also for being arranged on non-standard bolts or non-standard nuts in the counterbore with a certain depth, it is difficult to use a common wrench at all. Even if it can be inserted into the counterbore, and when the wrench is in use, the teeth on the wrench will often loosen and cannot tightly clamp non-standard nuts and bolts, so it is diff...
