[embodiment]

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

With reference to Fig. 1-2, holder adjusting device 1000 provided by the invention comprises base 100, be installed in trimming assembly 200 on the base 100, be installed in the rough adjustment feature 300 on the trimming assembly 200 and said trimming assembly 200 and rough adjustment feature 300 held straight tube The Cloud Terrace 400 within it.

Said base 100 comprises substrate 102, is contained in the backing plate 104 in the substrate 102 and is arranged on the liner plate 106 on the backing plate 104.Said base 100 is installed in the bottom of straight tube The Cloud Terrace 400, so that said trimming assembly 200 and rough adjustment feature 300 are fixed in the straight tube The Cloud Terrace 400.

With reference to figure 1-5, said rough adjustment feature 300 comprises notched plate 303 on the liner plate 106 that is arranged on base 100, be arranged on coulisse 302 on the notched plate 303, be arranged on ball plate 304 on the coulisse 302, be arranged on ball seat 306 on the ball plate 304, be contained in the spherical rocking bar 308 in the ball seat 306 and be set in the conical ring 301 at said spherical rocking bar 308 tops.

The central authorities of notched plate 303 form groove 3022, and a breach 3024 is then offered at the edge.

Coulisse 302 is placed on the notched plate 303, and chute plate hole 3024 is offered at the center of coulisse 302, forms a plurality of such as four chutes 3022 on the circumferential end surfaces of coulisse 302.The slope is formed on the bottom of each chute 3022.In addition, form lug 3026 on the circumferential surface of coulisse 302, be fixed with coarse adjustment handle 305 on it, be used for causing coulisse 302 rotations through stirring handle 305.

The ball 3042 that the outstanding down quantity in the bottom of ball plate 304 and said chute 3022 are identical.When ball plate 304 being placed on 302 last time of coulisse, said ball 3042 is contained in respectively in the middle of the corresponding chute 3022, and can in chute 3022, slide.

The bottom of said ball seat 306 has opening 3062.Fig. 5 has showed the structure of the rough adjustment feature 300 after the assembling.

The principle of work of rough adjustment feature 300 is described below.Promote or pulling coarse adjustment handle 305, the coulisse 302 that then is fixedly connected with handle 305 will rotate.Be formed on the coulisse 302 and the bottom is chute 3022 rotation of ramp structure; Because its bottom is a ramp structure; Therefore cause the ball 3042 on the ball plate 304 vertically to move up, so just cause ball plate 304 vertically to move upward, cause ball seat 306 vertically to move up then along with ramp structure; Because conical ring 301 is fixed in the straight tube The Cloud Terrace 400; And the liner plate 106 of notched plate 303 and the base 100 that is fixed on The Cloud Terrace 400 bottoms against, therefore impel spherical rocking bar 308 to be compressed between conical ring 301 and the ball seat 306, thereby realized fixing fast spherical rocking bar 308; Because camera (figure does not show) is fixed on the spherical rocking bar 308, has therefore just realized fixing fast the camera attitude.

The structure of trimming assembly 200 is described below.As Fig. 1,2 and Fig. 6-8 shown in, trimming assembly 200 comprises fine setting coulisse 204, is arranged on ball loading plate 206 and the stripper plate 208 of fine setting on the coulisse 204.

Form fine setting chute 2042 on the circumferential end surfaces of said fine setting coulisse 204, the bottom of chute 2042 is a ramped shaped.Outwards outstanding lug 2048 is equipped with trimming handle 201 on the circumferential surface of fine setting coulisse 204 on it.Shown in fine setting coulisse 204 is contained in the groove 3022 of notched plate 303, and lug 2048 is limited in the breach 3024 of notched plate 303 (with reference to figure 3).

The outstanding downwards ball 2062 in said ball loading plate 206 bottoms, said ball 2062 is contained in the fine setting chute 2042.

The top of said stripper plate 208 has intrados 2082.

Above-mentioned ball loading plate 206 is set in the ball plate 304 of rough adjustment feature 300; Said stripper plate 208 passes the chute plate hole 3024 of said coulisse 302 and the opening 3062 of ball seat 306 bottoms, and finally make its intrados 2082 and said spherical rocking bar 308 against.

Promote or pulling trimming handle 201, the fine setting coulisse 204 that then is fixedly connected with handle 201 will rotate.Be formed on the fine setting coulisse 204 and the bottom is fine setting chute 2042 rotation of ramp structure; Because its bottom is a ramp structure; Therefore cause the ball 2062 on the ball loading plate 206 vertically to move up along with ramp structure; So just cause ball loading plate 206 vertically to move upward, cause stripper plate 208 vertically to move up then, because conical ring 301 is fixed in the straight tube The Cloud Terrace 400; And fine setting coulisse 204 is resisted against on the notched plate 303 of rough adjustment feature 300; And the liner plate 106 of notched plate 303 and the base 100 that is fixed on The Cloud Terrace 400 bottoms against, therefore impel spherical rocking bar 308 to be compressed between conical ring 301 and the stripper plate 208, thereby realized fixing fast spherical rocking bar 308.Similarly, because camera (figure does not show) is fixed on the spherical rocking bar 308, therefore just realized fixing fast to the camera attitude.

Above-mentioned rough adjustment feature 300 is used to carry out coarse adjustment fast significantly, and trimming assembly 200 then is used for finely tuning by a small margin, thereby can fix the spherical rocking bar 308 on the The Cloud Terrace 400 easily.
