Regulation, realizes that the expansion link of step-less adjustment is also main based on threaded adjusting.The bad adaptability of the expansion link of threaded adjusting, be
This, the purpose of this utility model is to provide a kind of new technical scheme to solve existing technical problem.
The content of the invention
Specific technical scheme is as follows：
A kind of stepless adjustable and retractable lever apparatus, including outer bar 1, interior bar 2, location-plate 3.Outer bar 1 is enclosed on the outside of interior bar 2,
Location-plate is stuck in the notch of outer bar 1 and the formation of interior bar 2, is realized freely stretching in the range of certain length and is locked.
The beneficial effects of the utility model are：
（1）Without being the step-less adjustment that length of telescopic bar can be achieved by screw thread pair.
（2）It is simple in construction, it is easy to adjust quick.

Position plate.
Embodiment
Below in conjunction with the accompanying drawings, by embodiment, the utility model is further described.
Referring to Fig. 1, Fig. 2 and Fig. 3.Outer bar 1 is enclosed on outside interior bar 2, and the internal diameter of outer tube 1 is equal with the external diameter of interior bar 2, is all R.
Two bars relative can be slided.The location-plate of X-type is adjusted according to the relative position of outer bar 1 and interior bar 2, reaches the locked rod member phase of positioning
The purpose mutually moved.Fig. 1 and Fig. 2 represent adjusting rod maximum tension state and adjusting rod maximum collapse state respectively.
Referring to Fig. 4, a trapezoidal notch is respectively opened in the bottom front and rear sides of outer bar 1.Ensure axis of the notch in outer bar 1 of both sides
Direction is in reverse symmetrical.The short side of trapezoidal notch is L1, and long side is L2.
Referring to Fig. 5, Ge Kai mono- is away from shape notch about 2 for interior bar, and both sides of two notches respectively positioned at interior bar are symmetrical, simultaneously
The bottom surface of notch is less than the top surface of lower notch in guarantee, and this distance is L3.
Referring to Fig. 6, location-plate 3 is X-type, symmetrical up and down on center, and middle minimum width value is L1, distance center
Distance is at R（In figure shown in setting-out）Width is L2, and thickness is slightly less than L3.
Reference picture 3,, can be in rod member because the notch of two rod members is overlapping when outer bar 1 and interior bar 2 are set in together
There are two notches in both sides；Outer bar 1 can be respectively cut in the top of rectangular channel under the following of upper rectangular channel of interior bar 2, opposite side
Both sides trapezoidal notch.Fig. 3 is the trapezoidal microcephaly of cutting and cuts trapezoidal major part；Move up, cut trapezoidal as interior bar 2 is relative
Microcephaly, which can slowly become, cuts trapezoidal major part, and the trapezoidal microcephaly of cutting can be slowly become by cutting trapezoidal major part.X-type is positioned
It is symmetrical above and below that plate 3 is designed, and minimum place is equal with trapezoidal short side, is highly a width of L2 at R at distance minimum, and purpose is exactly,
After location-plate loads when the notch that outer bar 1 and interior bar 2 are overlapped to form, when side width is equal with cutting base, opposite side
Just one is surely consistent with the cutting top margin width of opposite side；Simultaneously because rod member must cause in the event of relatively moving
The change of both sides cutting edge width, and the location-plate adjusted can prevent this change.It is locked and positioning rod member so as to reach
Purpose., can running fix plate and outer bar 1 at the same time when needing to adjust rod length（Or move simultaneously
Location-plate and interior bar 2）, the flexible of rod member is realized by adjusting interior outer bar and left and right adjusting location-plate up and down.The thickness of location-plate 3
Be designed to be slightly less than L3, be in order to leave gap, will not be stuck so as to when needing to adjust rod length, easily
In operation.
