As further preferred version, also comprise: star tripod chassis; Said chassis comprises the center positioning hole 7 that is positioned at the central position; Be evenly distributed on around the positioning hole 7; And three link arms 72,73,74 that are connected with positioning hole 7; All there is a tripod locating slot 72,73,74 outer end of every link arm, and the Placement of link arm 72,73,74 and center positioning hole 7 is preferably hinged.
The present invention is with respect to the advantage of existing technology:
(1) design of " T " shape support makes that the horizontal reference point of instrument is very clear, and in engineering survey, as long as the cone centre and the ground measurement basic point of " T " shape support coincided, the horizontal reference point of instrument has just come out naturally.
(2) through rotation level adjuster adjusted bolt; With the terrestrial survey basic point is the summit, has realized the waving of support stick, and then can it have been adjusted to vertically; Because " T " shape support upper plane and support stick are vertical relations, and then have realized the leveling to upper plane; Regulate through regulating bolt, both convenient, precision is high again.
(3) in preferred version, increased star tripod chassis, three strong points of tripod can embed respectively in the locating slot of three link arms, can guarantee to realize fixing tripod on the higher ground of hardness; Simultaneously, star tripod center chassis positioning hole can allow the cone centre of " T " shape support to pass wherein, can guarantee to realize on the higher ground of hardness fixing to the cone centre of " T " shape support.
(4) be applied to the precision measuremnt field as the present invention, when for example carrying out trigonometric levelling, just will fill up traditional tripod design accuracy and stable aspect blank; Especially when this product and star tripod chassis are used; More can highlight its high superiority; Need not employ lot of manpower and material resources again and remove to make the concrete pile point; Cost is lower, flexible operation, precision high, good stability, for modernized precision measuremnt work provides superior condition easily.
