Description
Technical field
The utility model is related to a kind of dynamic torque tool, especially a kind of gap spanner.
Background technology
Spanner is a kind of commonly installation and extracting tool；Bolt, screw, nut and other spiral shells are twisted using lever principle
Line tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.
Spanner is usually formed with the opening or sets of holes of grip bolt or nut in the one or both ends of shank, when use threadingly
Direction of rotation applies external force in shank, can twist bolt or nut.
Now common monkey wrench is in loose nut, due to deviation, the fixed jaw and movable claw two of monkey wrench
Gripper edge on two diagonal sides of hex nut, at this point, the forced area of nut and spanner is small, generates the point of application of nut
Pressure can be very big, so being easy to the clamping face of the spanner of the arm of angle of damage nut.
There is also defects same as monkey wrench for another gap formula back-up wrench.
Invention content
The goal of the invention of the utility model is to provide a kind of gap spanner reducing the damage nut arm of angle.
The utility model adopts the following technical solution：
The front end of a kind of gap spanner, including wrench body, the wrench body is monkey wrench, the rear end of the wrench body
For back-up wrench, it is provided with the first friction structure on the movable claw clamping face of monkey wrench, is arranged on the clamping face of back-up wrench
There is the second friction structure；Fixed part length on monkey wrench is shorter than movable claw length, is provided on fixed part and movable claw phase
Parallel the first plane and be in 120 degree of the second plane with first plane included angle, the first plane is put down with movable claw clamping face
Row；First fixed jaw length of back-up wrench is shorter than the second fixed jaw length, be provided on the first fixed jaw third plane and
It is in 120 degree of fourth plane with the third plane included angle, the third plane is parallel with the clamping face on the second fixed jaw.
Using above-mentioned technical proposal the utility model compared with prior art, can reduce nut and spanner clamping face it
Between stress intensity, and the structure that rubs can increase coefficient of friction, and more conducively clamping is stablized.
Laterally thin horizontal dimpled grain structure is respectively adopted in first friction structure and the second friction structure.
First friction structure and the second friction structure use diamond groove structure.
The front end of wrench body and the rear end of wrench body are connected by shank, be provided on shank with hold when four refer to it is curved
The adaptable wavy shaped configuration of song.
Third friction structure is provided in wavy shaped configuration.
First plane is provided with the 4th friction structure, and the 5th friction structure is provided in third plane.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A direction views in Fig. 1.
In figure：Movable claw 1, movable claw clamping face 2, the first plane 3, the second plane 4, fixed part 5, wavy shaped configuration 6,
Two fixed jaws 7, clamping face 8, the first fixed jaw 9, third plane 10, fourth plane 11, shank 12.
Specific implementation mode
The front end of wrench body is monkey wrench in the present embodiment, and the rear end of wrench body is back-up wrench, monkey wrench
Movable claw clamping face 2 on be provided with the first friction structure, the second friction structure is provided on the clamping face 8 of back-up wrench；It is living
5 length of fixed part on wrench is shorter than 1 length of movable claw, and 5 length of fixed part on monkey wrench is shorter than 1 length of movable claw,
The length of fixed part 5 is shorter than the length of movable claw 1, is conducive to the clipping operation of crawl space.
First plane 3 parallel with movable claw 1 is provided on fixed part 5 and with first plane included angle in 120 degree
The second plane 4, the first plane 3 is parallel with movable claw clamping face 2；9 length of the first fixed jaw of back-up wrench is fixed than second
7 length of pawl is short, and 9 length of the first fixed jaw is shorter than 7 length of the second fixed jaw, is conducive to the clipping operation of crawl space.
It is provided with third plane 10 on first fixed jaw 9 and it is in 120 degree of fourth plane with 10 angle of third plane
11, the third plane 10 is parallel with the clamping face 8 on the second fixed jaw 7.
A plurality of transverse direction carefully horizontal dimpled grain structure is respectively adopted in first friction structure and the second friction structure, as shown in fig. 1.It is recessed
Enter part and clamping face part and form the surface of Non-smooth surface, so the larger friction structure of composition coefficient of friction, prevent spanner at
Rotation phenomenon is generated during exerting a force to nut.
Or first friction structure and the second friction structure diamond groove structure is respectively adopted, however it is not limited to it is above-mentioned cited
Support structure is ground, as long as meeting correlation can play the role of increasing coefficient of friction.
The front end of wrench body and the rear end of wrench body are connected by shank 12, are provided on shank 12 and when holding four
Refer to the adaptable wavy shaped configuration 6 of bending, third friction structure be provided in wavy shaped configuration 6, increases mill number when being conducive to hold,
Smooth rotation during anti-stop-band gloves.
First plane 3 is provided with the 4th friction structure, and being arranged in third plane 10 also has the 5th friction structure.
Improved structure in the present embodiment is not only conducive to the gripping of operating personnel under the premise of increasing coefficient of friction,
And can reduce to two plane intersections of nut at side damage.
