Abstract
The utility model relates to a ratchet ring spanner, the technical key points are that the utility model is provided with a ratchet mechanism, wherein the ratchet and a quincuncial socket are integrated into a body. A containing groove is arranged between a handle and a spanner head, the containing groove is provided with a pawl, a roller, and a flexible element; a surface of the pawl shows concave shape, the concave side of the pawl is contacted with the ratchet; the opposite side of the concave side of the pawl shows convex shape, two sides of the pawl also shows convex shape; through the flexible element the roller is contacted with the side of two convex sides of the pawl, the concave side of the pawl is contacted with the ratchet. When the open type dual direction ratchet ring spanner of the utility model is used to screw or relax the female screw, the spanner can be only turnover directly after being rotating a certain angle, the spanner can be continually screwed or relaxed without taking down the spanner from the female screw to turn around, thereby saving time and increasing the work efficiency. In the screwing process, the female screw is relaxed only by turning the convex part of two sides of the pawl, without taking down the spanner from the female screw, the spanner is turnover to sheathe the female screw to be rotated.
Description
Technical field
The utility model relates to a kind of spanner, and particularly a kind of double offset ring spanner with ratchet is specifically related to the two-way double offset ring spanner with ratchet of a kind of open type.
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 the two-way double offset ring spanner with ratchet of a kind of open type, and the two-way double offset ring spanner with ratchet of described open type has two-way rotating function, and volume is little, 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.
The two-way double offset ring spanner with ratchet of open type 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; Described ratchet both sides also are convex, and described storage tank two walls are provided with opening, and the projection of described ratchet both sides is passed described opening and stretched out wrench body.
One ball; Described ball is embedded in the described storage tank, and one of side of the exterior on described ratchet concave surface opposite offsets with described ball;
One elastic component, 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.
Use the two-way double offset ring spanner with ratchet of open type 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 the projection of ratchet both sides, will not take off from nut (or bolt) by spanner, anti-body puts and is rotated.The utility model has been saved the time, has improved operating efficiency.The two-way double offset ring spanner with ratchet volume of open type described in the utility model is little, can be suitable in a lot of occasions.
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 the two-way double offset ring spanner with ratchet of open type 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.The two-way double offset ring spanner with ratchet of open type comprises wrench body, and wrench body comprises the driving end 1 at two, handle 2; On every driving end, all be provided with through hole 3, be provided with ratchet coupling box 4 in the through hole 3.Ratchet coupling box 4 mainly is made up of coupling box 41 and ratchet 42, coupling box 41 and ratchet 42 concentrics, and ratchet 42 and coupling box 41 are structure as a whole.
Be provided with a storage tank 11 at handle 2 and 1 of driving end, storage tank 11 is made up of big storage tank 111 and little storage tank 112.Ratchet 5 is arranged 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.Spring 8 is arranged in the little storage tank 112, and ball 7 is embedded in the little storage tank 112, and ball 7 is installed between ratchet 5 and the spring 7.
The one side 52 that ratchet 5 and ratchet 42 offset is concavity, and the opposite 53 of concave surface 52 is convex; The two sides 54,55 of ratchet 5 also are convex.Big 111 liang of walls of storage tank are provided with opening 91,92, and the projection 54,55 of ratchet both sides is passed opening 91,92 and stretched out wrench body.Under the effect of spring 8, the side 531 or the side 532 on projection 53 both sides of ball and ratchet 5 offset, and the concave surface 52 and the described ratchet 42 of described ratchet 5 offset.
Stir the projection 54,55 of ratchet 5 both sides, when the right with ratchet 5 concave surfaces 52 of ratchet 42 offsets, ball 7 offsets with the side, the left side 532 of ratchet 5 projectioies 53, at this moment, the single head double offset ring spanner with ratchet is enclosed within on nut or the bolt, rotates counterclockwise spanner and dally, then produce moment of torsion clockwise.Otherwise then idle running clockwise produces moment of torsion counterclockwise.
