Description
Technical field
The utility model relates to manual screw tightening tools, more specifically to a kind of ratchet spanner.
Background technique
Ratchet spanner is a kind of manual screw tightening tool, and the more specification movable handle double offset ring spanner with ratchets of single head, double end are (fixed
Hole).It is to be connected by way of the negative key of hinged key and positive key occlusion by the main plum blossom-like sheath of different specification size and from plum-blossom sleeve
It connects.Since a plum-blossom sleeve tool is there are two the quincunx through-hole of specification, it is made to can be used for the elastic of two kinds of specification screws, from
And use scope is expanded, save raw material and work time cost.Movable trigger piece adjusts spanner and uses angle in which can be convenient.This
Kind spanner is used for the elastic operation of screw, has the characteristics of strong applicability, easy to use and low cost.
General ratchet spanner, including a wrench body, be equipped in the accommodating space on the wrench body head circlip,
Pawl, spring and ratchet, wherein the ratchet is made of Ratchet body and spacer, which is that a periphery is equipped with concave ring groove
Annulus, the spacer engagement sleeves be set to Ratchet body side.The ratchet spanner, by by the ratchet of original integral structure
Component is decomposed into be combined by Ratchet body and spacer and constitute, avoid the concave ring groove on original ratchet part on one side height while
Difficulty of processing caused by low, and since Ratchet body and spacer component processing are relatively easy, so that ratchet spanner processing life
Efficiency is produced to greatly improve, also reduce production cost.
Currently, all there is nut connection on any mechanical equipment, and dismounted, is needed by traditional spanner as far as possible
It ceaselessly to rotate back and forth, the most of the time is used for bolt freewheeling segments, swings back and forth, and labor intensity is high, takes time and effort.Separately
Outside, by equipment, this body structure is limited some nuts, and swing space is smaller, leads to the invisible increase of number of oscillations.
Utility model content
In view of the above defects of the prior art, the purpose of the utility model is to provide a kind of ratchet spanner, to
Quick detachable nut is realized, for the nut dismounting at small space, slit.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of ratchet spanner, comprising: wrench body, and it is connected in the nut set on wrench body head, further includes: power teeth
Wheel, transmission gear and spanner gear；
The spanner gear is connected and fixed with the nut set；
The transmission gear is co-planar gear set, and mainshaft gear is meshed with the spanner gear；
The power gear is meshed with the countershaft gear on the transmission gear；
Rotating handle is also connected in the power gear.
Transmission ratio between the power gear and transmission gear is 1:4~6.
The rotating handle is telescopic type rotating handle.
The spanner geared sleeve is set on the excircle of nut set, the axle center of the spanner gear and the nut set
Axle center coincide.
In the above technical solution, a kind of ratchet spanner provided by the utility model, structure is simple, novel in design,
Convenient for production, it can be achieved that Quick detachable nut, bolt, it can be used for small space, the nut at slit, bolt installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model ratchet spanner.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1, a kind of ratchet spanner provided by the utility model, comprising: wrench body 1, and be connected in and pull
The nut set 2 on 1 head of hand main body, above-mentioned is prior art content, and details are not described herein again.Unlike the prior art, also
It include: power gear 3, transmission gear and spanner gear 4.
Preferably, the spanner gear 4 is connected and fixed with nut set 2, the spanner gear 4 is set in the spiral shell
On the excircle of mother set 2, the axle center of the axle center of the spanner gear 2 and nut set 4 coincides, and makes its setting in being one
Overall structure.
Preferably, the transmission gear is co-planar gear set, mainshaft gear 5 is engaged with the spanner gear phase 4.
Preferably, the power gear 3 is meshed with the countershaft gear 6 on the transmission gear, the power gear 3 with
Transmission ratio between transmission gear is 1:4~6, to greatly improve efficiency.
Preferably, being also connected with rotating handle 7 in the power gear 3, the rotating handle 7 is that telescopic type rotates hand
Handle rotates rotating handle 7 by bolt direction of rotation, can quickly rotate bolt, finally by 2 fastening of nut set or release bolt.
In conclusion the utility model ratchet spanner is connected by gear, speed ratio is improved, accelerates speed.Structure is simple, if
Meter is novel, it can be achieved that Quick detachable nut, bolt, can be used for small space, the nut at slit, bolt installation.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all be fallen in the Claims scope of the utility model.
