The first embodiment is as follows:

as shown in fig. 1, it is a schematic structural diagram of the adjustable wrench of the present invention.

The front end of the wrench body 1 is provided with a fixed wrench opening, a tooth shape is arranged from one end of the fixed wrench opening to the middle position of the wrench opening, the tooth tip direction of the tooth shape faces the handle part of the wrench body 1, the movable wrench opening 5 is correspondingly installed with the fixed wrench opening, and the movable wrench opening 5 is connected with the wrench body 1 through a first adjusting structure. The bottom of the movable wrench mouth 5 is provided with a round shaft, the movable wrench mouth 5 is provided with two wrench mouth faces, the right wrench mouth face is perpendicular to the round shaft, the left wrench mouth face is not perpendicular to the round shaft and is provided with a second adjusting structure, the bottom of the round shaft is provided with a tooth shape, and the tooth shape starts from the left end of the round shaft and ends at a certain distance from the right end of the round shaft.

The first adjusting structure comprises a worm 2, steel balls 4 and a first return spring 3, a slide way and a square groove are arranged at the front end of a wrench body 1, the square groove is communicated with the middle part of the slide way, the left side wall and the right side wall of the square groove are respectively symmetrically provided with two sections of arc grooves 9, the central line of the worm 2 is provided with a through hole, the first return spring 3 and one steel ball 4 at each of two sides are placed in the through holes and then placed in the square groove, so that the steel balls 4 at two sides are in contact with the arc grooves 9 at two sides under the pressure of the first return spring 3, the worm 2 is positioned at the top of the square groove, a circular shaft of the movable wrench mouth 5 is inserted and installed in the slide way and is movably connected with the wrench body 1, a tooth form on the circular shaft is movably connected with the worm 2, when downward force is applied to the worm 2, the worm 2 moves downwards, the steel balls 4 compress the first return spring 3 under the pressure of the arc grooves 9 at two sides, when the worm 2 moves downwards to the bottom position of the square groove, the tooth form is separated from the tooth form at the bottom of the movable wrench mouth 5, the movable wrench mouth 5 can be quickly drawn out and installed in the direction when the adjustable worm 2 is removed, the force applied to the worm 2, the first return spring 4 and the first return spring is connected with the arc grooves, the steel balls 5, and the first return spring 5.

The second adjustment structure comprises a locking toothed block 8, a pin shaft 6 and a second reset spring 7, wherein a U-shaped cavity is arranged on the left opening face of the movable wrench opening 5, slide grooves are formed in two side walls of the U-shaped cavity, the left side of the locking toothed block 8 is flat and provided with a pin shaft hole, an elongated slot is arranged below the pin shaft hole, the second reset spring 7 is arranged on the lower portion of the pin shaft hole, the left side of the locking toothed block 8 is arranged in the U-shaped cavity, the pin shaft 6 penetrates through the pin shaft hole and is arranged in the slide groove, and a sliding inclined plane is arranged on the right side of the locking toothed block 8.

When the function is twisted to the thorn repeatedly need not using, the body 1 is twisted in pegging graft earlier to 5 round axle right-hand members in the activity, starts to end in the certain distance department from the round axle right-hand member from the round axle left end because of the tooth type, and arbitrary knob worm 2, the activity is twisted mouthful 5 and can not come off, when needs are twisted to the thorn repeatedly, the body 1 is twisted in pegging graft earlier to 5 round axle left ends in the activity.

When an operator holds the wrench body 1 and rotates clockwise along the direction shown in the figure, the fixed wrench opening and the anti-loosening tooth block 8 press the workpiece 10, and the workpiece 10 is driven to rotate. When an operator holds the wrench body 1 to rotate along the counterclockwise direction of the shown position, the whole wrench rotates counterclockwise by taking the axis of the workpiece 10 as the center, the workpiece 10 is in a stationary state at the moment, the workpiece is clamped when the sliding and withdrawing bevel slides to the end point of the workpiece 10, if the wrench continues to rotate along the counterclockwise direction, the anti-loosening toothed block 8 is driven by the extrusion force generated by the workpiece 10 on the sliding and withdrawing bevel, and meanwhile, the second return spring 7 is also driven by the anti-loosening toothed block 8 to be compressed; when the sliding inclined plane crosses the end point of the workpiece 10, the anti-loosening tooth block 8 slides under the elastic action of the second reset spring 7 to reset, the workpiece 10 is pressed by the fixed wrench opening and the anti-loosening tooth block 8 again, the whole process of return reversing is completed, the workpiece 10 can be driven to rotate again when an operator applies pressure along the clockwise direction again, and the wrench can continuously and rapidly ratchet and twist fasteners such as bolts and nuts in a reciprocating mode.
