Specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail:
Embodiment 1, with reference to a kind of accompanying drawing 1-2 duplicate gears of the present utility model, including base 1, central shaft 4, upper teeth portion 2nd, lower teeth portion 3 and action bars 5, central shaft 4 pass through upper teeth portion 2, lower teeth portion 3 to be located at the lower section of upper teeth portion 2, the insertion of the one end of central shaft 4 Base 1, lower teeth portion 3 is movably set on central shaft 4, and the central axis segment between lower teeth portion 3 and base 1 is provided with one end and is against down The lower section of teeth portion 3, the other end is against the spring on base, is additionally provided with to operate what teeth portion 2 and lower teeth portion 3 were separate on base 1 Action bars 5.
A kind of duplicate gear, the lower surface of upper teeth portion 2 and the lower upper surface of teeth portion 3 are mutually twisted.
A kind of duplicate gear, the lower surface of upper teeth portion 2 is the first clamping boss and the lower upper surface of teeth portion 3 for the second clamping is convex Platform, the first clamping boss and the second clamping boss are mutually fitted together to.
A kind of duplicate gear, the hole that the confession central shaft of lower teeth portion 3 is passed through to having the lower edge covered on the axial wall of center, under Along being inserted into base, and and the central axis segment in base 1 on spring one end connection.
A kind of duplicate gear, action bars 5 includes pull bar, spring and pushing block 6, and pull bar one end passes through base, on base 1 The drag link end of side is provided with pushing block 6, and the side lower surface of pushing block 6 keeps being connected with lower teeth portion 3, between base 1 and pushing block 6 Pull bar section outside be provided with one end and prop up pushing block 6, the other end props up the spring of base 1.
A kind of duplicate gear, is additionally provided with the jack 7 being used to through fixing bolt on pull bar.
