Description
Technical field
The utility model relates to a kind of spanner, and particularly two-way double offset ring spanner with ratchet is a kind of closed two-way double offset ring spanner with ratchet specifically.
Background technology
When pulling nut or bolt with existing double offset ring spanner, spanner can only turn an angle, and put the double offset ring spanner head again after nut (bolt) takes off angle of revolution, could continue to change an angle.Circulate so repeatedly up to nut (bolt) is tightened up or takes off.So use existing this double offset ring spanner, operating efficiency is not high.A kind of double offset ring spanner with ratchet is also arranged, and its excircle dimension is more much bigger than the excircle dimension of existing double offset ring spanner. and the axial length of sleeve also is three or four times of existing double offset ring spanner.Thereby the workable a lot of positions of existing double offset ring spanner, this double offset ring spanner with ratchet but can not be worked.
The utility model content
The purpose of this utility model is to propose a kind of closed two-way double offset ring spanner with ratchet, to solve the problems referred to above that present double offset ring spanner exists.
The utility model solves the problems of the technologies described above by the following technical programs:
Closed two-way double offset ring spanner with ratchet comprises wrench body, and wrench body comprises the driving end at two, handle; It is characterized in that at least one head also comprises:
One ratchet coupling box head has a through hole on the described driving end, be provided with a ratchet coupling box head in the described through hole; Described ratchet coupling box head comprises the coupling box and the ratchet of concentric;
One ratchet has a storage tank between described handle and driving end, be provided with a ratchet in the described storage tank; Described ratchet is provided with hole, also is provided with hole on the described wrench body, and bearing pin passes above-mentioned hole ratchet is installed on the wrench body; The one side of described ratchet is concavity, and the concave surface of described ratchet and described ratchet offset; The opposite of the concave surface of described ratchet is convex;
One ball; Described ball is embedded in the storage tank, and one of side of the exterior on the concave surface opposite of described ratchet offsets with described ball;
One elastic component, described elastic component is arranged in the storage tank, and the two ends of the flexible direction of described elastic component connect ball and storage tank cell wall respectively, and described ratchet and described ratchet offset under the effect of described elastic component;
One driving lever, described driving lever is fixedly installed on the ratchet, has a movement slots on the described wrench body, and one of described driving lever is goed deep in the described movement slots.
Use closed two-way double offset ring spanner with ratchet described in the utility model to screw or unscrew nut (or bolt), after turning an angle,, will not take off revolution from nut (or bolt) by driving end as long as directly revolution just can continue to screw or unclamp; Screw in the process, if want to unscrew nut (or bolt), as long as stir driving lever, will not take off from nut (or bolt) by spanner, anti-body puts and is rotated; Closed two-way double offset ring spanner with ratchet described in the utility model can be saved the working time, increases work efficiency, because volume is little, so the occasion that can be suitable for is many.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of an embodiment of closed two-way double offset ring spanner with ratchet described in the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1, closed two-way double offset ring spanner with ratchet comprises wrench body, and wrench body comprises the driving end 1 at two, handle 2; Wherein on the driving end 1 through hole 3 is arranged, be provided with a ratchet coupling box head 4 in the through hole 3; Ratchet coupling box head 4 mainly is made up of the coupling box 41 and the ratchet 42 of concentric, and ratchet 42 and coupling box 41 are structure as a whole.1 of handle 2 and driving end have a storage tank 11, and storage tank 11 is made up of big storage tank 111 and little storage tank 112.Be provided with a sour jujube 5 pawls in the big storage tank 111; Ratchet 5 is provided with hole 51, also is provided with the hole (not shown) on the wrench body, and bearing pin 6 passes above-mentioned hole ratchet 5 is installed on the wrench body; Ratchet 5 is concavity with the one side 52 that ratchet 42 offsets, and the opposite 53 of the concave surface 52 of described ratchet is convex;
Be inlaid with a ball 7 in the little storage tank 112, the projection on the concave surface opposite of ratchet 5 53 on one side side 531 or 532 and ball offset;
Also be provided with a spring 8 in little storage tank 112, the two ends of spring 8 flexible directions connect ball 7 and little storage tank cell wall respectively, and ball 7 ratchets 5 offset under the effect of described spring 8, and ratchet 5 offsets with described ratchet 42;
Fixedly not establishing the person on ratchet 5 has a driving lever 54, and described driving lever 54 is fixedly installed on the ratchet 5, has a movement slots 9 on the described wrench body, and one of described driving lever 54 is stretched in the described movement slots 9.9 position-limiting actions of movement slots.
Stir driving lever 54, when driving lever 54 was in the right-hand member of movement slots 9, the projection 53 of ratchet 5 was in the right of ball 7, and ratchet 5 right-hand members are inclined upwardly, and its concave surface 52 the right and ratchet 42 offset.At this moment, closed two-way double offset ring spanner with ratchet is enclosed within clockwise rotates spanner on nut or the bolt and can produce moment of torsion, then will occur idle running counterclockwise.Otherwise then rotate counterclockwise spanner and can produce moment of torsion, then will occur idle running clockwise.
Use closed two-way double offset ring spanner with ratchet described in the utility model to screw or unscrew nut (or bolt), after turning an angle, as long as directly revolution, just can continue to screw or unclamp, will not take off revolution from nut (or bolt) by driving end, save the time, improved operating efficiency.Screw in the process, if want to unscrew nut (or bolt), as long as stir driving lever 54, will not take off from nut (or bolt) by spanner, anti-body puts and is rotated.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
