Cautious holding mobile phone is in horizontality, and in an unguarded moment, as long as mobile phone is slightly tilted a bit to one side, the body of rod will horse
Upper rotation, mobile phone is followed with regard to knockdown, uses extremely inconvenience, can not take some photos with angle of inclination；
2nd, the second generation has the circular telescopic lever of single groove（As shown in Figure 2）, although the second generation increased than the first generation
Single groove, the large rotation of the body of rod being prevented effectively from, but, the body of rod is only fluted on one side, and the body of rod still can be certain
In the range of twist, still to keep the balance of mobile phone just to take photo as possible when using, use still inconvenient；
3rd, the third generation has the telescopic lever of dual-cavity（As shown in Figure 3）, the telescopic lever of dual-cavity effectively improves bar
The problem of body twisting, property easy to use is greatly improved.With the extensive application of double flute telescopic lever, the third generation stretches
The weak point of pull bar is also day by day revealed, and its deficiency is mainly manifested in following two aspects：One be it is anti-shake, resistance to tension not
Foot, the body of rod elongate after if subjected to after a certain degree of horizontal force, the tight ness rating of the body of rod can be deteriorated, if during stretching with
The too quickly body of rod that will result in of power is separated and makes product rejection；Two is that anti-torsion ability is not enough, remains to make the body of rod when firmly twisting
In interior wrench deformation in a big way and cannot restore.
Utility model content

Section, the inner diameter values of indent flat segments are little compared with the inner diameter values of outer tube and inner diameter values of indent flat segments compared with positive stop spring plate external diameter value
Little, the bottom of inner tube offers spacing hole, and the bottom of positive stop spring plate is provided with the spacing preiection towards projecting inward extension, spacing
Projection is intercalated in the spacing hole of inner tube.
Wherein, each hollow tube is aluminium alloy body.
The beneficial effects of the utility model are：A kind of telescopic lever knot for being applied to self-shooting bar described in the utility model
Structure, it includes at least two hollow tubes being set with successively from the inside to the outside, each hollow tube be respectively provided with two just to arrangement and
The flange for radially protruding respectively, each flange shaping extruded with corresponding hollow tube is into a single integrated structure；In two neighboring
Positive stop spring plate is installed between blank pipe body, two neighboring hollow tube is followed successively by inner tube, outer tube, and it is straight that outer tube upper end arranges indent
Section, indent flat segments inner diameter values are little compared with outer tube diameter value, positive stop spring plate external diameter value, the spacing hole and positive stop spring plate of inner tube bottom
The spacing preiection of bottom is engaged.By said structure design, the utility model have novel in structural design and it is anti-shake, tension
Stretch, antitorque dynamic stable performance, the advantage of long service life.
