Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of multi-functional shifter lever spanner, comprise axis body 1, first gear 2, second gear 3, spring 4, handle 5, loop bar 6 and card wheel 12, the end of described axis body 1 is regular polygon.Described handle 5 is connected on described second gear 3, described second gear 3 is rotating to be enclosed within described axis body 1, on described axis body 1, the side of described second gear 3 is provided with the block 7 preventing described second gear 3 axially-movable, on described axis body 1, the other side of described second gear 3 is provided with the snap ring I 13 and external tooth that prevent the second gear 3 axially-movable, and the first gear 2 can not axially-movable under the effect of block 7 and snap ring I.Described first gear 2 is provided with the internal tooth matched with described axis body 1 external tooth, and described first gear 2 is enclosed within described axis body 1 by the described internal tooth of the first gear 2 and cooperatively interacting of the external tooth of described axis body 1.
Described loop bar 6 has one at least, and one end of described loop bar 6 is the working end 10 matched with screw, and described working end 10 is regular polygon, and other one end of described loop bar 6 is link 11, and described link 11 is regular polygon groove.The working end 11 of the end being enclosed within described axis body 1 that described link 11 is fixing or other described loop bar 6.
On described axis body 1, described first gear 2 has described spring 4 and described card wheel 12 away from the side cover of described second gear 3, described card wheel 12 is enclosed within described axis body 1 by the cooperatively interacting of external tooth of the internal tooth on it and described axis body 1, and described spring 4 to be between described first gear 2 and described card wheel 2 and to prop up described first gear 2, make the side tooth of the side tooth of described first gear 2 and described second gear 3 mutually meshing, the side tooth of described first gear 2 and the side tooth of described second gear 3 comprise the chamfered portion 8 that cooperatively interacts and face part 9 directly, on described axis body 1, described card wheel 12 is provided with away from the side of described spring 4 snap ring II 14 preventing the axially-movable of described card wheel 12.Card wheel 14 can not move under the effect of snap ring II 14 on axis body 1 direction, another one direction limit by spring 4.
Rotate forward handle 5, the first gear 2 can be driven to rotate by the second gear 3.Because the first gear 2 is meshing with axis body 1, first gear 2 rotates and axis body 2 can be driven to rotate, link 11 fixed cover of loop bar 6 is in the end of axis body 1, final loop bar 6 also rotates thereupon, the working end 10 of final loop bar 6 realizes loosening or screwing screw, and whole process spring 4 does not rotate.In above process, first can put the loop bar 6 of respective numbers according to the particular location of screw, loop bar 6 can directly put or take off, and saves the working time.Secondly, in the impact of the object or space that are limited to screw adjacency, when can not rotate forward handle 5 continuously, when handle 5 can not continue to rotate forward, rotate backward handle 5, the external tooth of the first gear 2 and the external tooth of the second gear 3 can skid along chamfered portion 8, therefore, handle 5 rotates the rotation that can not drive miscellaneous part, after handle 5 rotates backward certain angle, just can continue to rotate forward screw generation effect.And unlike existing spanner, need whole spanner to take down from screw, readjust position, just can work on after alignment screw again, a screw loosen or screw work, need repeated multiple timesly to carry out above-mentioned adjustment, serious affects operating efficiency.Screw or releasing screw, just can be realized by the different ends link 11 of loop bar 6 being enclosed within axis body 1, be tightening screw when the link 11 of loop bar 6 is enclosed within axis body 1 one end, the link 11 of loop bar 6 be enclosed within axis body 1 in addition one end time be releasing screw.
The present invention can make the spanner of respective model according to the model of different screw, for the dismounting of screw, particularly in flight-line maintenance field, can shorten screw disassembly and assembly time, provide operating efficiency greatly.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
