Abstract
The utility model relates to a wrench with double jaws which is used for fastening a fastener. Each wrench head of a traditional wrench is provided with only one jaw, and an angle between a handle and the wrench head is not adjustable. The novel wrench is characterized in that each wrench head is provided with two different sizes of jaws, and the definite angle is adjusted by the wrench head around the handle; the wrench can also be provided with a ratchet mechanism to adapt to different working conditions. Compared with the traditional complete set of wrench, the wrench can be used as two traditional wrenches. The utility model has the advantages of small volume, light weight, and low cost.
Description
The utility model is to pull mouth spanner about a kind of bilayer, is used for the fastening of fastenings.
No matter traditional spanner is slow-witted spanner, plum blossom spanner or Socket type driving end of wrenches, and each stature only contains one pulls mouth.Such as fork spanner, it is made up of two spanners that vary in size of handle and two ends thereof, promptly one can only pull two nuts that vary in size to fork spanner.
The purpose of this utility model is the spanner that will provide a kind of bilayer to pull mouthful, for example one can pull four nuts that vary in size to fork spanner.
The utility model is achieved in that it comprises the spanner of handle and handle end, and improvements are that each spanner is provided with two of varying in size and pulls mouth.Described spanner can be slow-witted spanner, plum blossom spanner and Socket type driving end of wrenches.Described spanner can be connected on the handle with bearing pin, so that can rotate by thorny handle, perhaps directly is fixed on the handle.Between plum blossom spanner or Socket type driving end of wrenches and handle ratchet mechanism can be set.
The utility model has the advantages that: a spanner can replace two spanners of conventional spanner, thus dwindled tool set volume, weight reduction, reduce production costs.

Fig. 6 is the slow-witted spanner of the utility model, the combination wrenches form that the plum blossom spanner is formed.
Fig. 7 is the combination wrenches form that the slow-witted spanner of the utility model, Socket type driving end of wrenches are formed.
Fig. 8 is the form that ratchet mechanism is set between plum blossom spanner of the present utility model or Socket type driving end of wrenches and handle.
For ease of further understanding the utility model, below contrast figure be described in more detail.
Embodiment 1(sees Fig. 1, Fig. 2, Fig. 3) this is that slow-witted spanner (7) adopts double-deck form of pulling mouth.As seen pull mouthful (1) among Fig. 3 less than pulling mouthful (2), promptly can pull two nuts that vary in size.In addition, handle (3) is to wipe mutually for fear of the hand and the plane of operation with the gradient that the plane (5) at nut (4) place forms.
Embodiment 2(sees Fig. 4, Fig. 5) this is that double offset ring spanner adopts double-deck form of pulling mouth.As seen pull mouthful (12) among the figure greater than pulling mouthful (11), wherein plum blossom spanner (6) is connected on the handle (3) with bearing pin (10), so that can turn an angle by thorny handle, operates under different operating modes thereby adapt to.
Embodiment 3(sees Fig. 6), this pulls the plum blossom spanner (6) of mouth and the combination wrenches that the double-deck slow-witted spanner (7) of pulling mouth is formed by bilayer.
Embodiment 4(sees Fig. 7).This pulls the Socket type driving end of wrenches (8) of mouth and the combination wrenches that the double-deck slow-witted spanner (7) of pulling mouth is formed by bilayer.Wherein collet head is fixed together with handle (3).And slow-witted spanner (7) can turn an angle by thorny handle.
Certainly, other composition form can also be arranged.For example the handle two ends are Socket type driving end of wrenches that two bilayers that vary in size are pulled mouth.Perhaps, spanner can rotate by thorny handle, also can be fixed on the handle.
Embodiment 5(sees Fig. 8) this is the form that ratchet mechanism (9) are set between the plum blossom spanner pulled mouthful of bilayer or Socket type driving end of wrenches and handle.Can certainly adopt the ratchet mechanism of other type.Here no longer be described herein.
