Specific embodiment

The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model Protection scope, the pause mark in the utility model indicates the relationship of sum.

As shown in Figure 1-Figure 3, a kind of macro holder, the cloud including long straight provided by the utility model embodiment Platform track 1, and be mounted on holder track can be along the holder slide 2 of the length direction linear slide of holder track；

The holder slide 2 is equipped with the slide locking bolt 23 for being locked in holder slide on holder track, and Camera for assembling camera connects bolt 8, and dismountable Quick-mounting board 9 for assembling camera；Holder slide 2 by Two sliding blocks 21,22 form, which fills the span of a man's arms holder track 1, and adjusts bolt by an orbit gap (not shown) is fixed to each other, and two sliding blocks 21,22 can adjust the rotation of bolt with orbit gap, along holder track 1 width direction separates, closes up；Pass through adjustable two sliding blocks 21,22 of rotation track gap adjustment bolt and holder track 1 Between gap so that holder slide can smoothly be slided in holder track, while being avoided that holder slide in holder rail again Play in the width direction in road；

The holder track 1 is equipped with rotatable screw rod 3, and the screw rod 3 is parallel with the length direction of holder track 1, One end of screw rod 3 is coaxially fixed with turntable 4, and screw rod 3 is equipped with the drive block 7 being threadedly engaged with it；

It is printed with the circular scale 41 enclosed around disk axes one on the turntable 4, is fixed with graduated scale on holder track 1 Know part 5, the rotation scale marker line 51 for indicating turntable current scale is printed on scale marker part 5, turntable 4 is equipped with one Rotatable rocking handle 6, the rocking handle and turntable bias are laid；

The drive block 7 is fixed to each other with holder slide 2 by a screw rod gap adjustment bolt 71, screw rod gap adjustment Bolt 71 is equipped with elastomeric element 72, which is laid between drive block 7 and holder slide 2, and the elastic portion Part is respectively held against drive block and holder slide；By rotary screw rod gap adjustment bolt 71, adjustable drive block and holder are sliding Gap between seat compensates the gap using the elasticity of elastomeric element, and holder slide and circular scale are realized Zero position；

In the utility model embodiment, the turntable 4 is a circular disk body, and circular scale 41 is printed on the periphery of turntable On, in the utility model other embodiments, circular scale can also be printed in the disk of turntable, in this case, turntable can also To be designed to the other shapes such as polygon.

In the utility model embodiment, the elastomeric element 72 on the driving gap adjustment bolt is elastic using having Gasket, in the utility model other embodiments, which can also be using other flexible components such as spring.

In the utility model embodiment, it is printed on the holder track 1 for indicating holder slide in holder track The scale of present position, the bottom of holder track 1 offer the screw hole for connecting camera shooting tripod.

As shown in figure 4, the screw rod 3 is mounted on holder track 1 by screw rod bearing 31 in the utility model embodiment On, the turntable 4 adjusts bolt 42 by a turntable clearance and is fixed on screw rod end, and turntable 4 and one of silk The way of contact of rod bearing 31 is face contact, and the rotational stability of turntable can be improved by the way of face contact, pass through rotation Turntable clearance adjusts bolt, the contact elasticity of adjustable turntable and screw rod bearing, so that turntable can be rotated smoothly, together When be avoided that radial-play again.

The utility model embodiment needs the occasion of accurate mobile camera especially suitable for macroshot etc., by cloud when use Platform track is mounted on camera shooting tripod by the screw hole of bottom, and camera can connect bolt by camera or Quick-mounting board is mounted on On holder slide；Turntable will drive screw rod when rotating and rotate together, and the rotation of screw rod then can drive drive block along holder track Length direction it is mobile, finally drive holder slide to move with camera along the length direction of holder track by drive block.

When controlling camera movement, the rocking handle driving turntable for first passing through eccentric laying is quickly rotated, so that holder slide exists Quick sliding is to position (whether reach estimate position can identify by the scale on holder track) estimated on holder track, Then turntable slow rotation is controlled, and accurately controls the moving distance of holder slide by the circular scale on turntable, is passed through The turnning circle of screw rod can be scaled the moving distance of holder slide, holder slide by rotation scale marker line and circular scale After reaching exact position, holder slide is locked using slide locking bolt, camera can be positioned.
