Embodiment

Below in conjunction with the accompanying drawing in the present embodiment, carry out specifically, clearly and completely describing to the technological scheme in embodiment.

Shown in Fig. 1-11, a kind of multi-functional mini bracket, the base 12 comprising the support arm 11 for setting up the equipment such as camera or astronomical telescope and be hinged with support arm 11, support arm 11 can carry out coarse adjustment rotation relative to base 12, base 12 is provided with intermeshing worm gear 14 with the hinged place of support arm 11, worm screw 15, with the link 16 be provided with for intermittent connecting support arm 11 and worm gear 14 of base 12 hinged place on support arm 11, when link 16 connecting support arm 11 and worm gear 14, support arm 11 can at worm gear 14, carry out fine setting relative to base 12 under the drive of worm screw 15 to rotate.

When the non-connecting support arm 11 of link 16 and worm gear 14, be only flexibly connected between support arm 11 and base 12, rotating support arm 11, thus regulate the angle between support arm 11 and base 12, so, the object of coarse adjustment angle rapidly can be realized; When link 16 connecting support arm 11 and worm gear 14, be also connected by worm gear 14, worm screw 15 between support arm 11 with base 12, rotary worm 15, worm gear 14 rotates thereupon, thus drives support arm 11 to rotate, and then realizes the fine setting of angle between support arm 11 and base 12.The rotation angle of support arm and base usually at 0 degree of-90 degree, but is not limited to 0 degree of-90 degree.

When support arm 11 rotates to time arbitrarily angled, this bracket can use as the camera carriage of specialty and carry out the photography of general specialty, such as wide viewing angle photo, distant view photograph, lapse photography etc., this bracket also can use as the equatorial telescope of a single shaft, make support arm 11 to rotate with geosychronous speed, thus celestial body is followed the tracks of, and carry out the shooting of astronomical photo, when support arm 11 and base 12 one-tenth 90 degree, this bracket can use as theodolite bracket, realizes the automatic star-seeking to celestial body and following function.

Shown in Fig. 3,6 and 7, concrete, worm screw 15 is inserted in the mounting hole matched with it on base 12 vertically, worm gear 14 is sheathed in the installation shaft on base 12, and worm gear 14 and worm screw 15 engage each other, meanwhile, a round sides and the support arm 11 of worm gear 14 fit.

See Fig. 6, 7, shown in 10 and 11, link 16 comprises the bayonet lock 162 that disk handle 161 and two are fixedly arranged on disk handle 161 side symmetrically, disk handle 161 is provided with annular knurl, bayonet lock 162 is divided into two sections, comprise the first portion be connected with disk handle 161 side and the second portion be connected with described first portion, wherein, the diameter of first portion is greater than the diameter of second portion, support arm 11 offers two bayonet lock hole slots 111 with the hinged place of base 12, wherein, bayonet lock hole slot 111 comprises the first cell body matched with the first portion of bayonet lock 162 and the second cell body matched with the second portion of bayonet lock 162 (size of the first cell body is greater than the size of the second cell body), and the first cell body is connected with the second cell body, two bayonet locks 162 are inserted in corresponding bayonet lock hole slot 111 respectively, one side of worm gear 14 offers a plurality of attachment hole 141 matched with the second portion of bayonet lock 162.

Shown in Fig. 1,6 and 11, support arm 11 and base 12 are hinged by relative and first rotating shaft 13 of establishing and the second rotating shaft 17, preferably, the side of disk handle 161 is screwed with the axle head of the first rotating shaft 13 and is connected (not shown), and the central axis of the central axis of disk handle 161 and the first rotating shaft 13 on the same line.

Shown in Fig. 6 and 7, one end of worm screw 15 is provided with the rotating handles 151 for regulating worm screw 15 to rotate, and the head of rotating handles 151 is provided with knurling structure, can rotary worm 15 easily by rotating handles 151.Support arm 11 is provided with the chute 112 for setting up the equipment such as camera or astronomical telescope, those shootings or scope by being inserted in from the card article arranged with it in the chute 112 on support arm 11, also can being threaded connection and being fixed on support arm 11.

When carrying out finely tuning the angle between support arm 11 and base 12, pressing link 16 makes it the progresses inside to support arm 11, now, the first portion of bayonet lock 162 is arranged in the first cell body of bayonet lock hole slot 111, and the second portion of bayonet lock 162 injects in the attachment hole 141 on worm gear 14, so, achieve being fixedly connected with between support arm 11 with worm gear 14, rotary worm 15, worm gear 14 again, thus support arm 11 can be driven to rotate, and realize the fine adjustment of angle; When the angle between coarse adjustment support arm 11 and base 12 need be carried out, extract the movement outside that link 16 makes it to support arm 11, now, the second portion of bayonet lock 162 departs from the attachment hole 141 on worm gear 14, the first portion of bayonet lock 162 falls into the second cell body of bayonet lock hole slot 111, thus the connection between support arm 11 and worm gear 14 is disconnected, now, rotating shaft is the unique connecting body between support arm 11 and base 12, then hand rotation support arm 11 can realize the coarse adjustment of angle.

Above-mentioned embodiment; be only and technical conceive of the present invention and structure characteristic are described; object is to allow the stakeholder being familiar with technique implement according to this; but above said content does not limit the scope of the invention; every any equivalence done according to Spirit Essence of the present invention changes or modifies, and all should fall within protection scope of the present invention.
