Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig.1-3, it is a kind of can Lengthened moment arm spanner, including the first running-on 1, the surface and first of the first running-on 1
One end of handle 2 is fixedly connected, and the top and bottom of the inner wall of first handle 2 are fixed respectively at the top and bottom of fixed block 3
Connection, first handle 2 are fixedly connected with block 4 on the inner wall far from fixed block 3, the side of fixed block 3 is fixedly connected with snap ring
5, the inner wall of snap ring 5 is fixed with one end of fixture block 6 and is clamped, and the other end of fixture block 6 is fixedly connected with one end of second handle 7, the
The top of two handles 7 is fixedly connected with limited block 8, passes through setting for fixed block 3, block 4, snap ring 5, fixture block 6 and second handle 7
It puts, spanner is allow to realize the situation that the arm of force lengthens, the arm of force for solving the problems, such as existing spanner is all to fix length, is avoided
When bolt is unable to turn and laborious situation, limited block 8 since the arm of force of spanner is too short fixed too tight when
With the quantity of block 4 it is equal there are two, and the position of two limited blocks 8 and two blocks 4 is relatively fixed, and two limited blocks 8 and two
The size of a block 8 is identical, and top of the second handle 7 far from limited block 8 offers limit hole 9, the inside of limit hole 9 and limiting
One end clamping of bar 10, the quantity of limit hole 9 are no less than six, and the distance between each limit hole 9 is one centimeter, and each
The size of limit hole 9 is adapted with the size of gag lever post 10, and the other end of gag lever post 10 passes through the bottom of sliding sleeve 11 and pulling plate 12
It is fixedly connected, sliding sleeve 11 is embedded in the top of first handle 2, by the setting of sliding sleeve 11, gag lever post 10 is allow preferably to slide
Dynamic, bottom of the pulling plate 12 far from gag lever post 10 is fixedly connected by spring 13 with the top of first handle 2, passes through limited block 8, limit
The setting in position hole 9, gag lever post 10, pulling plate 12 and spring 13 makes spanner that can be solved when bolt is twisted with the arm of force of Lengthened wrench
Determined spanner the too short and stubborn motionless bolt of the arm of force situation, improve the process of work in this way, avoid the waste of manpower,
Top of two handles 7 far from limit hole 9 is fixed to be fixedly connected with one end of kelly 14, and there are two the quantity of kelly 14, and two
Identical the distance between the distance between kelly 14 and limit hole 9 are one centimeter, and the other end of kelly 14 is interior with card slot 15
Portion is clamped, and by being used cooperatively for kelly 14 and card slot 15, spanner is allow not need to preferably be combined when lengthening,
Card slot 15 is opened in the other end of first handle 2, and the other end of second handle 7 is fixedly connected with the second running-on 16, the first running-on 1
Be both provided with anti-skidding teeth on the inner wall of the second running-on 16, and the diameter of the first running-on 1 and the second running-on 16 is respectively eight public affairs
Point and five centimeters, it is rational in infrastructure, it is easy to operate, convenient for promoting and using, be capable of the arm of force of effective Lengthened wrench, make bolt can
Preferably to turn, use spanner more convenient.
In use, by pulling pulling plate 12, gag lever post 10 is made to be detached from limit hole 9, then second handle 7 is pulled out, is made
Second handle 7 forget about it needs position then my pulling plate 12 come loose, gag lever post 10 is resetted by spring 13, make gag lever post 10 and
Limit hole 9 is clamped, and then second handle 7 is fixed, and completes the elongation of the arm of force.
In summary：This can Lengthened moment arm spanner, pass through fixed block 3, block 4, snap ring 5, fixture block 6 and second handle 7
Setting, allow spanner realize the arm of force lengthen situation, the arm of force for solving the problems, such as existing spanner is all to fix length,
Avoid when bolt fixed too tight when due to the arm of force of spanner too it is short be unable to turn with laborious situation, pass through
The setting of limited block 8, limit hole 9, gag lever post 10, pulling plate 12 and spring 13 allows spanner to be lengthened when bolt is twisted and pulls
The arm of force of hand solves the situation of the too short and stubborn motionless bolt of the arm of force of spanner, improves the process of work in this way, avoid people
The waste of power, it is rational in infrastructure, it is easy to operate, convenient for promoting and using, it is capable of the arm of force of effective Lengthened wrench, makes bolt can be with
It preferably turns, uses spanner more convenient.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
