Specific embodiment
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.It should be noted that, accompanying drawing of the present invention is all in the form of simplifying and all using non-essence
Accurate ratio, only in order to purpose that is convenient, lucidly aiding in illustrating the embodiment of the present invention.
As shown in Figure 1 to Figure 3, the present invention provides a kind of rotating extensible arm, comprising: interior bar 2, outer bar 1 and knob external member 3；
Wherein, described interior bar 2 and outer bar 1 are hollow type pipe and the cooperation of both gaps, and described interior bar 2 and outer bar 1 open up respectively
There is helicla flute 5, and two groups of helicla flutes 5 are symmetrical, described knob external member 3 is by the fixing described interior bar 2 of described helicla flute 5 and outer bar 1.
The present invention pass through arrange helicla flute 5, because described helicla flute 5 is symmetrical arranged, between inside and outside bar 2,1 be subject to multi-angle frictional force and
Shearing controls, more firm.And arbitrarily mobile between inside and outside bar 2,1, do not controlled by modulus, random length can be taken and appoint
Meaning angle, realize rod member level infinitely flexible and 360 degree rotate freely positioning.
Preferably, described spiral expanding bar also includes the fixing foot 6 positioned at interior bar 2 and outer bar 1 end, described fixation
Foot 6 is used for being connected with vertical rod 4, and then so that spiral expanding bar is fixed.
With reference to Fig. 3, described knob external member 3 includes ring for fixing 301 and the bolt assembly being located on described ring for fixing 301 to emphasis
302, described bolt assembly 302 gos deep in described helicla flute 5 after passing through described ring for fixing 301, affixed with described inside and outside bar 2,1.
Preferably, described interior bar 2 and outer bar 1, all using coating steel pipe, have the characteristics that intensity is high.Specifically, described
Interior bar 2 is adopted using the coating steel pipe of a diameter of 48mm, described ring for fixing 301 using the coating steel pipe of a diameter of 38mm, outer bar 1
