Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.It should be noted that attached drawing of the present invention is all made of simplified form and uses non-essence
Quasi- ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the 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, the interior bar 2 and outer bar 1 are hollow type round tube and the two clearance fit, are opened up respectively in the interior bar 2 and outer bar 1
There is helicla flute 5, and two groups of helicla flutes 5 are symmetrical, the knob external member 3 passes through the fixed interior bar 2 of the helicla flute 5 and outer bar 1.
The present invention is by setting helicla flute 5, since the helicla flute 5 is symmetrical arranged, between inside and outside bar 2,1 by multi-angle frictional force and
Shearing control, it is more firm.And arbitrarily moved between inside and outside bar 2,1, it is not controlled by modulus, random length can be taken and appointed
Meaning angle realizes that rod piece is horizontal unlimited flexible and 360 degree rotate freely positioning.
Preferably, the spiral expanding bar further includes the fixed feet 6 positioned at 1 end of interior bar 2 and outer bar, the fixation
Foot 6 fixes spiral expanding bar for connecting with upright bar 4.
Emphasis includes retainer plate 301 and the bolt assembly being located on the retainer plate 301 referring to Fig. 3, the knob external member 3
302, the bolt assembly 302 gos deep into the helicla flute 5 after passing through the retainer plate 301, affixed with the inside and outside bar 2,1.
Preferably, the interior bar 2 and outer bar 1 are all made of coating steel pipe, have the characteristics that intensity is high.Specifically, described
Interior bar 2 uses diameter to use diameter to use for the coating steel pipe of 48mm, the retainer plate 301 for the coating steel pipe of 38mm, outer bar 1
