Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1, the utility model provides a kind of technical solution: one kind having adjustable wrench, fork spanner, double offset ring spanner three Unify the quick coach wrench of notch wheel of function, including driving end 1, pulls mouth 2, spanner handle 3, return leaf spring 4, hexagon socket head cap screw 5, pin shaft 6.1 lower part of driving end opens up crack slot up and down, which is used to spanner handle 3 being embedded in driving end, pulls 2 bottom of mouth and open up tooth Tooth, and the bottom teeth for pulling mouth 2 are placed in the guide groove for the left and right perforation that driving end 1 opens up, on crack slot up and down End and the guide groove of left and right perforation are connected state, and spanner handle 3 protrudes into the slot of crack, pulls 3 upper head teeth of body handle and pulls mouth 2 Teeth are mutually engaged, and driving end 1, spanner handle 3 open up corresponding mounting hole simultaneously, and mounting hole is with pin shaft 6 by driving end and spanner handle It connects together, such spanner handle 3 becomes lever mechanism by pin shaft, and 4 lower end hexagon socket head cap screw 5 of return leaf spring, which is fixed on, to be pulled At hand on 1 crack slot inner wall, 4 upper end of return leaf spring compresses and pulls on 2 side of mouth, in short, the utility model is joined using gear mesh Dynamic plus lever principle makes to pull mouth and spanner handle flexible motion, can allow and pull outspoken speed folding and pull the activity folding on driving end 1 of mouth 2. Described pull opens up V-groove on mouth and the corresponding force surface of driving end i.e. working face.

It is as shown in Figure 2: under the pressure of return leaf spring 4, mouth 2 to be pulled when not working in impaction state, by side when use It to 1 with below finger push driving end 1, is quickly opened to realize and pull mouth 2, the ruler of nut A can be accommodated when pulling mouth 2 and being opened to After very little, the finger for pushing driving end 1 is unclamped, pulls mouth 2 at this time under the pressure of return leaf spring 4, Automatic-clamping nut.Spanner handle 3 It is mutually engaged by teeth with 2 teeth of mouth are pulled, locking state is under the connection of pin shaft 6, at this point, adjustable wrench, fork spanner, plum blossom The quick coach wrench of notch wheel of the three-in-one function of spanner is in the locked position of ratcher function, can only exert a force along direction 2 as common Adjustable wrench uses, and can not achieve repeatedly the stubborn function of spine.

As shown in Figure 3: when spanner fastens the fasteners such as bolt, nut, spanner rotation can be reached by reaching spanner When the extreme position turned, spanner is rewound by direction 3 at this time, wrench opening 2 is in the state that do not stress, spanner handle 3 when due to rewinding Teeth occlusion is pulled 2 teeth of mouth and is displaced outwardly, and when size reaches B, spanner is in and completely disengages nut, continues to revolve along direction 3 at this time Turn, when pulling mouth 2 and 1 head V-groove of driving end is consistent with nut angle, by the pressure of return leaf spring 4, wrench 2 is quick again Be engaged nut, to reach ratcher function, repeatedly along 2,3 rotating spanner of direction, to reach continuous quickly to bolt, spiral shell Mother's handling.

The utility model structure is simple, design rationally, it is easy to manufacture, using, it is easy to operate, it is time saving and energy saving, can both make It is used for common adjustable wrench, and can be used as coach wrench of notch wheel use, while the type of tool can be greatly reduced, and also have Locking functions.It can guarantee that operator carries out continuous rapidly spine to fasteners such as bolt, nuts in production work and twists, significantly It improves work efficiency.

In the description of the present invention, it should be understood that temporald eixis or positional relationship are based on the figure Orientation or positional relationship is merely for convenience of description the utility model, rather than the device or element of indication or suggestion meaning must There must be specific orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
