The specific embodiment

Now cooperate the graphic following preferred embodiment of enumerating, in order to structure of the present utility model and effect are elaborated.

Please consult Fig. 1 to Fig. 2 earlier, be the spanner 10 of the utility model first preferred embodiment, include a lever 20, two and adjust screw 30, two driving ends 40, four shell fragments 50, two positioning components 60, and two ratchet groups 70.

Lever 20 is formed by bipole body 22 butt joints, makes the two ends of this bipole body 22 form a socket 24 respectively, and form the profile groove 26 of this two socket 24 of connection between this bipole body 22.In addition, the wherein madial wall of a body of rod 22 of lever 20 has two appearance holes 28.Grip lever 20 for the convenience of the users, can be at the outer peripheral face of lever 20 sheathed by the made grip of soft material (as plastics).

This two is adjusted screw 30 and passes profile groove 26 by the two opposite sides of lever 20 respectively and screw togather with this bipole body 22, in order to adjusting the spacing between this bipole body 22, that is adjusts the size of profile groove 26.

Please cooperate and consult Fig. 4, each driving end 40 is articulated in an end of lever 20 by a pivot 42, and respectively have two heads 44, this two head 44 can selectively be placed in the socket 24 of lever 20 by the pivot of each driving end 40, and having a shrinkage pool 46 and an installing hole 48 respectively, the aperture of each installing hole 48 is all inequality.

Each shell fragment 50 is sheathed on a wherein end of a pivot 42, and elastic top supports the wherein head 44 of a driving end 40, so that the suitable resistance head 44 to driving end 40 to be provided.

Each positioning component 60 has an elastic component 62 and positioning piece 64.Elastic component 62 is located in the appearance hole 28 of lever 20, and with keeper 64 towards driving end 40 ejections.When keeper 64 was sticked in the shrinkage pool 46 of driving end 40, driving end 40 just can't pivot and finish the location, as shown in Figure 4.

Each ratchet group 70 is a known structure, holds at this and does not give unnecessary details its detail structure.The size of each ratchet group 70 matches with the size of one of them installing hole 48 respectively and is removably installed in wherein in the installing hole 48, and each ratchet group 70 has a scalariform trepanning 72, as shown in Figure 3, the aperture of these scalariform trepannings 72 is all inequality, makes these ratchet groups 70 can cooperate the nut of eight kinds of different sizes to use.

Via said structure as can be known, please cooperate and consult Fig. 5, when using spanner 10 of the present utility model, the user can rotate a wherein driving end 40 according to the nut size of desire locking, and the ratchet group 70 that allows size match can reach the effect of locking with scalariform trepanning 72 with the nut interlock.In driving end 40 rotating process, the elastic top that can be subjected to shell fragment 50 is supported and is avoided any rotation, in case when driving end 40 turned to the location, keeper 64 just can be sticked in the shrinkage pool 46 of driving end 40 by the thrust of elastic component 62, to finish the location of driving end 40, as shown in Figure 4; In addition, the user also can see through an instrument (as screwdriver) this two adjustment screw 30 is unscrewed or screws, in order to adjust the size of profile groove 26, make this bipole body 22 of lever 20 can bestow the suitable pressure of driving end 40, cooperate the elastic force effect of shell fragment 50 simultaneously, allow the velocity of rotation of driving end 40 can not adjust to optimal state too fast or excessively slowly.

Please consult Fig. 6 again, the spanner 80 that is provided for the utility model second preferred embodiment, its primary structure and the foregoing description are roughly the same, its difference only is that lever 82 is not to be formed by the bipole body butt joint, and have two profile grooves 86, each profile groove 86 is communicated with a wherein socket 84, and adjusts by a size of adjusting 88 pairs of profile grooves 86 of screw respectively, to reach the purpose of this utility model.

The utility model is taken off disclosed composed component among the embodiment in preceding, only for illustrating, is not to be used for limiting scope of the present utility model, and substituting or variation of other equivalence element also should be claim scope of the present utility model and contain.
