As shown in figure 26, in being in when carrying, assembling is considered, support of the present invention is split point with threaded connection place, splits into following components:
First component B: be made up of with the first link 11 being connected clip assembly 10 and cardan universal joint component 2 clip assembly 10 for clamping mobile phone or card type digital camera.
Second portion C: be made up of with the The Cloud Terrace link 11 ' for being connected The Cloud Terrace 10 ' and cardan universal joint component 2 The Cloud Terrace 10 ' for connecting digital camera or vidicon camera, the fixing-assembly of this structure is identical with The Cloud Terrace with the link that common tripod uses, be suitable for fixed card formula digital camera, slr camera and vidicon camera etc. have the digital product of standard thread interface, because the existing mobile phone overwhelming majority does not possess standard thread interface, therefore fixing mobile phone is not suitable for, components A and part B are two kinds of forms of fixed structure, it functionally supplements mutually, user can select according to fixed product type, all shootings on market can be met, the demand of photography series products.
Part III D: form primarily of the first pin pipe in cardan universal joint component 2 and balance weight assembly 3.
Part IV E, pulls down the Handleset 22 in cardan universal joint component 2 and forms parts separately.
Part V F: the entirety that crus secunda pipe 31 and supporting component 32 are connected to form.
Part VI G: balancing weight 4.
The compound mode of its parts of support of the present invention has multiple, can meet the multiple shoot function requirements such as hand-held shooting, auto heterodyne, establishing shot, provide several conventional compound mode below.
(1), the first function is hand-held shooting, and this function has again three kinds of compound modes:
(1), the first compound mode as shown in figure 16, be made up of first component B, Part III D, Part IV E, Part V F, supporting component 32 is hidden in crus secunda pipe 31, is suitable for supporting mobile phone, the less photography and vedio recording product of card type digital camera class weight.If Part III D and Part V F concentric, in the process of shooting, the vertical section that Part III D and Part V F is formed can produce swing, the effect of impact shooting, by Part III D and Part V F after the first hinge 301, second hinge bending, form the hand-held shooting of " it " font structure, just can reduce swing, improve the quality of shooting.
(2), the second compound mode as shown in figure 17, be made up of second portion C, Part III D, Part IV E, Part V F, Part VI G, supporting component 32 is hidden in crus secunda pipe 31, is suitable for supporting slr camera, the photography and vedio recording series products that vidicon camera class weight is larger.
(3), the third compound mode as shown in figure 21, support taken by the short and small type be made up of first component B or second portion C and Part IV E, and this support does not have stabilization function, be suitable for general mobile phone or card type digital camera shooting.
(2), the second function is establishing shot, and this function has again two kinds of compound modes:
(1), the first compound mode is as Figure 18, shown in Figure 19, by second portion C, Part III D, Part IV E, Part V F, Part VI G is formed, supporting component 32 takes out in crus secunda pipe 31, oppositely be screwed in the lower end of crus secunda pipe 31, three supporting foots 321 form supporting structure, in Figure 19, the pin pipe of the first pin pipe assembly 30 extends, form higher height, in Figure 18, the pin pipe of the first pin pipe assembly 30 extend keep and, be suitable for supporting slr camera, the high-angle shot of the photography and vedio recording series products that vidicon camera class weight is larger, if need supporting mobile phone, the less photography and vedio recording product of card type digital camera class weight, second portion C is replaced with first component B by this on above-mentioned basis, as shown in figure 12.
(2), the second compound mode as shown in figure 23, by second portion C, Part V F, Part VI G is formed, supporting component 32 takes out in crus secunda pipe 31, oppositely be screwed in the lower end of crus secunda pipe 31, three supporting foots 321 form supporting structure, the height of this support is lower than the first above-mentioned compound mode, be suitable for supporting slr camera, the middle angle shot of the photography and vedio recording series products that vidicon camera class weight is larger, if need supporting mobile phone, the less photography and vedio recording product of card type digital camera class weight, second portion C is replaced with first component B by this on above-mentioned basis.
(3) low shooting function, the compound mode of this structure as shown in figure 22, be made up of second portion C and supporting component 32, the height of this compound mode is minimum, be suitable for the low angle shooting supporting slr camera, photography and vedio recording series products that vidicon camera class weight is larger, if need the less photography and vedio recording product of supporting mobile phone, card type digital camera class weight, second portion C is replaced with first component B.
(4) Self-timer, the compound mode of this structure as shown in figure 20, be made up of first portion B and Part III D, first pin pipe assembly 30 can reach longer length after extending, and lightweight, be suitable for the auto heterodyne supporting mobile phone, the less photography and vedio recording product of card type digital camera class weight.
Certainly, more than only give several conventional compound mode, parts of the present invention also have the combination of other form, as long as the equalization done according to protection scope of the present invention is modified and change, within the scope all belonging to the invention protection.
