Cylinder rotates together, skidding occurs；If nut is arranged in the small space that hand can not stretch into, nut is difficult to from screw
Upper disengagement.
The content of the invention
The purpose of the present invention is：A kind of double-end ratchet wrench is proposed, effectively to prevent in the case of nut loosening
There is skidding, be easy in the small space that can not be stretched into hand, it is convenient that nut is dismounted.
The technical scheme is that：A kind of double-end ratchet wrench, including a Single-head ratchet wrench, Single-head ratchet wrench
Including wrench body 1, the ratchet in wrench body 1, the pawl assembly of elastic collar 6 and the 1st, wrench body 1 is by one end
Ratchet sleeve connect composition with the handle of the other end, have a ratchet mounting hole on ratchet sleeve, an end of ratchet mounting hole
Mouth carries the convex shoulder of interior receipts, has an annular card on the inner cylinder face of ratchet mounting hole, close to the position of another port
Mounting groove is enclosed, elastic collar 6 is located in collar mounting groove, has on the inner cylinder face of ratchet mounting hole, close to the position of handle
One pawl assembly installation groove, described ratchet are clockwise 1st ratchet including a ratchet direction, the 1st ratchet
Component is made up of the 1st ratchet 3, the 1st spring 4 and the 1st spring base 5, and the 1st spring base 5 is located at the 1st in pawl assembly installation groove
In spring base mounting groove, one end of the 1st spring 4 is connected with the connection handle of the 1st spring base 5, the other end of the 1st spring 4 and the 1st spine
The ratchet engagement of the connection handle connection of pawl 3, the 1st ratchet 3 and the 1st ratchet；Described ratchet is a double end ratchet (2), described
Double end ratchet (2) include the 1st ratchet located above and the 2nd ratchet that is located below, the ratchet direction of the 2nd ratchet is the inverse time
Pin direction；Also include the 2nd pawl assembly, the 2nd pawl assembly is made up of the 2nd ratchet 7, the 2nd spring 8 and the 2nd spring base 9, the 2nd bullet
Spring abutment 9 is located in the 2nd spring base mounting groove in pawl assembly installation groove, one end of the 2nd spring 8 and the company of the 2nd spring base 9
Handle connection is connect, the other end of the 2nd spring 8 is connected with the connection handle of the 2nd ratchet 7, the ratchet engagement of the 2nd ratchet 7 and the 2nd ratchet.
It is an advantage of the invention that：A kind of double-end ratchet wrench is proposed, can effectively be prevented in the case of nut loosening
There is skidding, be easy in the small space that can not be stretched into hand, it is convenient that nut is dismounted.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is Fig. 1 B-B sectional views.
Embodiment
The present invention is described in further details below.Referring to Fig. 1 to Fig. 3, a kind of double-end ratchet wrench, including a list
Head ratchet spanner, Single-head ratchet wrench include wrench body 1, the ratchet in wrench body 1, the spine of elastic collar 6 and the 1st
Claw assembly, wrench body 1 are connected with the handle of the other end by the ratchet sleeve of one end and formed, and have a ratchet installation on ratchet sleeve
Hole, a port of ratchet mounting hole carry the convex shoulder of interior receipts, on the inner cylinder face of ratchet mounting hole, close to another port
Position have an annular collar mounting groove, elastic collar 6 is located in collar mounting groove, in the inner cylinder face of ratchet mounting hole
There is a pawl assembly installation groove position of upper, close handle, and described ratchet includes a ratchet direction for side clockwise
To the 1st ratchet, the 1st pawl assembly is made up of the 1st ratchet 3, the 1st spring 4 and the 1st spring base 5, and the 1st spring base 5 is located at ratchet
In the 1st spring base mounting groove in component installation groove, one end of the 1st spring 4 is connected with the connection handle of the 1st spring base 5, and the 1st
The other end of spring 4 is connected with the connection handle of the 1st ratchet 3, the ratchet engagement of the 1st ratchet 3 and the 1st ratchet；Described ratchet is
One double end ratchet (2), described double end ratchet (2) include the 1st ratchet located above and the 2nd ratchet that is located below, and the 2nd
The ratchet direction of ratchet is counterclockwise；Also include the 2nd pawl assembly, the 2nd pawl assembly is by the 2nd ratchet 7, the and of the 2nd spring 8
2nd spring base 9 forms, and the 2nd spring base 9 is located in the 2nd spring base mounting groove in pawl assembly installation groove, the 2nd spring 8
One end is connected with the connection handle of the 2nd spring base 9, and the other end of the 2nd spring 8 is connected with the connection handle of the 2nd ratchet 7, the 2nd ratchet 7
With the ratchet engagement of the 2nd ratchet.
The present invention operation principle be：When the rotate counterclockwise of wrench body 1 works, fixing nut can provide certain torque
The 1st spring 4 is compressed, now the external output torque of ratchet engagement of the 1st ratchet 3 and the 1st ratchet, the 2nd spring 8 pulls the 2nd ratchet 7
Slided in the 2nd ratchet tooth surface, the torque of the 1st ratchet output can make nut loosening.After nut loosening, the countertorque of nut offer
Disappear, the 1st spring 4 can not be compressed, and wrench body 1 and nut rotate together with, and skidding occur, and now, the 2nd ratchet starts
Work, the 2nd spring 8 are compressed, the external output torque of ratchet engagement of the 2nd ratchet 7 and the 2nd ratchet, and the moment of torsion substitutes nut and carried
The torque of confession, compress the 1st spring 4 so that the ratchet engagement of the 1st ratchet 3 and the 1st ratchet, wrench body 1 and nut stop beating
It is sliding.So repeatedly, most nut screws out from shank of screw at last.
