Detailed description of the invention

In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model it is described further and illustrates。

The concrete structure of this utility model embodiment is as shown in Figures 1 to 7。

As depicted in figs. 1 and 2, foldable structure includes the union joint 24 of the expansion link movable end for fixing connection self-shooting bar。

As depicted in figs. 1 and 2, clamping device 10 includes substrate 14, is fixed on lower plate 12 and the upper clip arm 13 of substrate 14 bottom。Upper clip arm 13 is located at the top of substrate 14。Upper clip arm 13 and lower plate 12 are for clamping the both sides of the portable capture apparatus such as mobile phone or panel computer。Upper clip arm 13 can move relative to substrate 14 so that the spacing scalable between upper clip arm 13 and lower plate 12, to adapt to the portable capture apparatus of different in width。Wherein, upper clip arm 13 can move relative to substrate 14, and lower plate 12 and substrate 14 are relatively fixed。Upper clip arm 13 can belong to prior art relative to the concrete structure that substrate 14 moves, and repeats no more herein。

Self-shooting bar can realize controlling capture apparatus by line traffic control, so will necessarily with line and connecting plug, so that connecting plug will not arbitrarily rock, the lower middle position at substrate 14 is provided with the slot 141 for holding connecting plug, as depicted in figs. 1 and 2。

As depicted in figs. 1 and 2, upper clip arm 13 is provided with two parts of symmetry, forms the holding tank 130 for holding expansion link when folding between two parts。

As depicted in figs. 1 and 2, union joint 24 includes body 240 and two symmetrically arranged hangers 241。Being fixed with bearing pin 25 on union joint 24, bearing pin 25 runs through two hangers 241。Lower plate 12 bottom surface is provided with mean for the connection cylinder 11 that bearing pin 25 is through。Being provided with the passage 243 for passing through for lower plate 12 when clamping device 10 overturns around bearing pin 25 between bearing pin 25 and union joint 24 body 240 of union joint 24, passage 243 is defined by two hangers 241, bearing pin 25 and union joint 24 body 240。When clamping device 10 is folding until when clamping device 10 is completely folding (holding tank 130 of upper clip arm 13 is enclosed within expansion link 30 as shown in Figure 7), lower plate 12 is placed in passage 243, therefore can considerably reduce folding volume along Fig. 1 direction E。

The axial-rotation degree of freedom of bearing pin 25 is zero。As depicted in figs. 1 and 2, termination 251 cross section of bearing pin 25 is regular pentagon, and hangers 241 is provided with the regular pentagon through hole 242 for being inserted in bearing pin 25 regular pentagon termination 251。After the through hole 242 of hangers 241 is inserted in bearing pin 25 termination 251, bearing pin 25 just cannot rotate relative to hangers 241。Certainly, in other embodiments, regular pentagon all can be made in two terminations of bearing pin。

As shown in Figure 3 and Figure 4, the fold mechanism 20 of the present embodiment also includes threaded post 21 and the thread barrel 22 with internal thread hole。

As shown in Figures 3 to 6, threaded post 21 front end is with external screw thread, and threaded post 21 rear end is inserted in bearing pin 25, and threaded post 21 can around bearing pin 25 central axis。The external screw thread that thread barrel 22 internal thread hole is with threaded post 21 matches, and namely the external screw thread of threaded post 21 is threaded with the internal thread hole of thread barrel 22, and therefore threaded post 21 can be threaded in or out the internal thread hole of thread barrel 22。

As shown in Figures 4 to 6, the outer end of thread barrel 22 is fixed with handle 23, it is possible to improve experience when threading cylinder 22 or internal thread broaching cylinder 22, it is also possible to improve appearance。

As shown in Figure 3 and Figure 4, clamping device 10 end is provided with mean for the connection cylinder 11 that bearing pin 25 is through。Connect cylinder 11 and be divided axially into two parts of formed objects along bearing pin 25, leave between two parts that run through for threaded post 21, allow threaded post 21 around the gap 12 of bearing pin 25 middle shaft rotation。

Locking and releasing process:

1), when clamping device 10 being locked, by twist grip 23, thread barrel 22 (Fig. 3 direction A) clockwise is screwed in, be threaded to the nozzle of thread barrel 22 be connected cylinder 11 outer wall and mutually support and thread barrel 22 can not screw in till；Now, thread barrel 22 produces thrust (Fig. 6 direction C) to connecting cylinder 11, and fixed bearing pin 25 is produced pulling force (Fig. 6 direction D) by threaded post 21, connect and can produce mutual thrust between cylinder 11 inwall and bearing pin 25 outer wall, cause needing overcoming the bigger frictional force between the two can turning and clamping device 10, therefore clamping device 10 is locked, it is impossible to upset。

2) when clamping device 10 being unlocked, by twist grip 23, thread barrel 22 (Fig. 3 direction B) counterclockwise is screwed out, the thrust connected between cylinder 11 inwall and bearing pin 25 outer wall tapers into, frictional force between the two also can taper into, time frictional force vanishing, clamping device 10 just unlocks completely, unfettered, it is possible to overturn around bearing pin 25 easily。

As it is shown in fig. 7, the self-shooting bar of the present embodiment includes the fold mechanism 20 of clamping device 10, expansion link 30 and the present embodiment, the holding tank 130 of upper clip arm 13 is enclosed within expansion link 30, and lower plate 12 is placed in passage。

Set forth above only further illustrate technology contents of the present utility model with embodiment; so that reader is easier to understand; but not representing embodiment of the present utility model and be only limitted to this, any technology done according to this utility model extends or recreation, all by protection of the present utility model。
