Abstract

The utility model discloses a multi -functional shifting wrench, including being equipped with the fixed nipper and movable splint, worm thumb wheel, handle that clamps the tooth, be equipped with the pincers tooth of pawl formula on the clamping face of fixed nipper, activity splint, the pincers tooth of fixing nipper, activity splint is corresponding the setting, and the prong of pincers tooth is fixed the pincers increment of nipper, activity splint and is personally submitted the opening at certain inclination all towards clockwise to adjust opening size through the worm thumb wheel. The utility model discloses a diagonal pliers increment face that is equipped with the pawl makes shifting wrench form pincers increment that better pincers held effect, especially pawl formula and can form fine pincers and hold in the face of twisting bald spare part, non -parallel face part and tubulose class object to having expanded multi -functional application, having enlarged its application scope, the shifting wrench that has solved prior art is only limited to plane centre gripping operation, problem that the function is comparatively single, just the utility model discloses simple structure, low in manufacturing cost are honest and clean, but wide application in hardware and tools technical field.

Description

A kind of multifunction active mouth spanner

Technical field

The utility model relates to hardware & tools technical field, particularly relates to a kind of multifunction active mouth spanner.

Background technology

In prior art, shfting wrench is a kind of conventional installation and removal instrument, utilize lever principle to twist bolt, the opening hand tools of nut, manually can regulate the position of ambulatory splint, opening and bolt or nut are adapted, there is the advantage of highly versatile, but the general positioning precision of its ambulatory splint is poor, cause ambulatory splint in use can form skew, consequently often occur twisting skidding, even often there is the situation of twisting bald parts, particularly it often can not be made to loosen the dead parts of rust, moreover, its plane opening is only limited to plane clamping operation, to twisting bald parts, non-parallel face part and tubulose type objects cannot turn at all, thus limit the scope of application.

Utility model content

For making up the weak point of above-mentioned technology, the utility model provides a kind of function multifunction active mouth spanner many, applied widely, and the shfting wrench fundamentally solving prior art is only limited to the comparatively single problem of plane clamping operation, function.

A kind of multifunction active mouth spanner of the utility model, comprise the fixing nipper and ambulatory splint, worm screw thumb wheel, handle that are provided with pincers tooth, it is characterized in that, the clamping face of described fixing nipper, ambulatory splint is provided with the pincers tooth of pawl formula, the pincers tooth of described fixing nipper, ambulatory splint is arranged in corresponding, the crown of pincers tooth is all towards clockwise direction, and the pincers increment face of described fixing nipper, ambulatory splint is the opening at certain inclination angle, and regulates openings of sizes by worm screw thumb wheel.

As preferably, the pincers increment face of described fixing nipper and the pincers increment face of ambulatory splint are 15 ° of angles.

The beneficial effects of the utility model are: make shfting wrench form pincers holding effect fruit preferably by the diagonal cutting pliers increment face being provided with pawl, thus power held by the pincers increasing pincers increment face, solve traditional shfting wrench ambulatory splint positioning precision difference and cause twist skidding, and the pincers increment of pawl formula is in the face of twisting bald parts, non-parallel face part and tubulose type objects can form well pincers holding effect fruit, thus extend multifunctional application, expand its scope of application, the shfting wrench fundamentally solving prior art is only limited to plane clamping operation, the problem that function is comparatively single, and the utility model structure is simple, cheap for manufacturing cost, hardware & tools technical field can be widely used in.

Wherein, 1, fixing nipper; 2, ambulatory splint; 3, tooth is clamped; 4, worm screw thumb wheel; 5, handle.

Detailed description of the invention

Below in conjunction with embodiment, a kind of multifunction active mouth spanner of the utility model is further described and is set forth.

See Fig. 1, Fig. 2, a kind of multifunction active mouth spanner of the utility model, comprise the fixing nipper 1 and ambulatory splint 2 that are provided with pincers tooth 3, worm screw thumb wheel 4, handle 5, it is characterized in that, described fixing nipper 1, the clamping face of ambulatory splint 2 is provided with the pincers tooth 3 of pawl formula, described fixing nipper 1, the pincers tooth 3 of ambulatory splint 2 is arranged in corresponding, the crown of pincers tooth 3 is all towards clockwise direction, can certainly all towards counterclockwise, described fixing nipper 1, the pincers increment face of ambulatory splint 2 is the opening at certain inclination angle, jaw opens formation articulation port, held to form pincers to the object matched with openings of sizes by pincers increment face, and regulate openings of sizes by worm screw thumb wheel 4, after jaw vises object, utilize pawl structure, larger pincers can be formed in the clockwise direction and hold power, and slip over less resistance when twisting counterclockwise.

As preferably, the pincers increment face of described fixing nipper 1 and the pincers increment face of ambulatory splint 2 are 15 ° of angles.

During use, stir worm screw thumb wheel 4 with adjusting jaw size, make the openings of sizes of jaw with clamp the bolt held, nut type objects size matches, jaw opens formation articulation port, held to form pincers to object by pincers increment face, after jaw vises object, push down jaw turn handle 5 clockwise, utilize the pawl structure of jaw end face, larger pincers can be formed and hold power, when turn amplitude is less, turn handle 5 counterclockwise again, due to pawl structure, jaw can slip over body surface with less resistance, and then push down jaw turn handle 5 clockwise, and so forth, the pincers action industry to object can be realized.
