Description
Technical field
The invention belongs to Wrench technical fields, and in particular to a kind of novel ratchet spanner.
Background technique
With the development of machinery field technology, risen many machine tools, wherein spanner just there are many kinds of,
Such as hook spanner, box spanner, allen wrench, torque spanner, ratchet spanner, the working efficiency of ratchet spanner higher,
It is more laborsaving when work, it when in use, only needs once repeatedly can back and forth exert a force with work pieces mates such as nuts, is not required to allow spanner
Continually cooperate and unclamp with nut etc., so, the use of ratchet spanner is more universal.But current ratchet spanner makes
Used time installation is inconvenient, and the connection of ratchet and wrench body is also unreliable, is easy to appear loosening.
Summary of the invention
To solve the above problems, the object of the present invention is to provide a kind of novel ratchet spanner, use when, is more preferably installed.
A kind of novel ratchet spanner, including handle, wrench body and ratchet, the handle is connect with wrench body, described
Wrench body is equipped with threaded hole and ratchet slot, and the threaded hole is connected to the ratchet slot, and the ratchet is embedded in the ratchet
In slot, it is equipped with U-shaped limiting slot equipped with perforative internal square hole, outer circle circumferential direction in the middle part of the ratchet, is set in the threaded hole
There is screw, the bottom of the screw is caught in the U-shaped limiting slot.
To install when being easy to use, the quadrangle of the internal square hole is equipped with chamfering.
For the connection convenient for wrench body and ratchet, the open end of the U-shaped limiting slot and the outer circumference surface of the ratchet
Concordantly.
Novel ratchet spanner of the present invention, compared with prior art, the beneficial effect is that: the configuration of the present invention is simple, installation
Convenient and connection is reliable, unidirectional to limit, and ensure that the service life of ratchet, with zero when the chamfering of internal square hole setting is easy to use
The cooperation of part.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of novel ratchet spanner body element of the present invention；
Fig. 2 is the assembling schematic diagram of novel ratchet spanner of the present invention.
As shown in the figure, 1- handle, 2- wrench body, 3- threaded hole, 4- ratchet slot, 5- ratchet, 6- internal square hole, 7- are U-shaped
Limiting slot, 8- screw.
Specific embodiment
Principles and features of the present invention are described with reference to embodiments, illustrated embodiment is served only for explaining this hair
It is bright, it is not intended to limit the scope of the present invention.
As shown in Figure 1, 2, a kind of novel ratchet spanner, including handle 1, wrench body 2 and ratchet 5, the handle 1 with pull
Hand ontology 2 connects, and the wrench body 2 is equipped with threaded hole 3 and ratchet slot 4, and the threaded hole 3 is connected to the ratchet slot 4, institute
It states ratchet 5 to be embedded in the ratchet slot 4, perforative internal square hole 6 is equipped in the middle part of the ratchet 5, outer circle circumferential direction is equipped with U
Type limiting slot 7, the threaded hole 3 is interior to be equipped with screw 8, and the bottom of the screw 8 is caught in 7 in the U-shaped limiting slot.
To install when being easy to use, the quadrangle of the internal square hole 6 is equipped with chamfering.
For the connection convenient for wrench body 2 and ratchet 5, the open end of the U-shaped limiting slot 7 and the outer circle of the ratchet 5
Circumferential surface is concordant.
When using the present invention, ratchet 5 is mounted in ratchet slot 4, screw 8 is then screwed into from threaded hole 3, adjusts ratchet
5, to guarantee that 3 bottom of screw enters in U-shaped limiting slot 7, installing be can be used.
The configuration of the present invention is simple, easy for installation and connection is reliable, unidirectional to limit, and ensure that the service life of ratchet, and interior four
Square hole setting chamfering be easy to use when and part cooperation.
Protection scope of the present invention is not limited to technical solution disclosed in specific embodiment, all skills according to the present invention
Art any modification, equivalent substitution, improvement and etc. substantially to the above embodiments, each fall within protection scope of the present invention.
