A tripod constructed as shown in is commonly used. The tripod is composed of a leg 21 on which a surveying instrument (not shown) is placed and three legs 22. In the hole 21a provided at the center of the leg head 21, a constant center 23 having an external thread corresponding to the screw provided at the upper part of the bottom plate of the surveying instrument is supported so as to be movable horizontally. There is.

It includes a middle rod 27 to be fitted and a clamp 28 attached to the lower end of the side rod 24. According to this, the leg 2 can be moved by relatively sliding the grounded middle rod 27 and the side rod 24.
2 expands and contracts as a whole, and by tightening the clamp 28, the both-side bar 24 and the middle bar 27 are fixed, and the surveying instrument can be set to an appropriate height.

シットを載置し、定心かん２３を締める。First, a tripod is arranged substantially on the side point, the three legs 22 are expanded and contracted to adjust the leg head 21 to an appropriate height, and each clamp 28 is tightened. At this time, the leg 21 is set to be visually horizontal. Then, the transit is placed on the leg 21 and the constant-center can 23 is tightened.

That is, the constant center is slightly loosened, and the transit is moved while collimating the centripetal telescope to align the side point and the base point. Once aligned, tighten the centering pin 23 to ensure that the transit is secured to the tripod.

First, the leg 22 is expanded and contracted while observing a preliminary leveler such as a circular water pipe so that the transit is substantially horizontal. When the leveling work by extending and contracting the legs is completed, next adjust the leveling screw accurately while looking at the vertical and horizontal water tubes (bubble tubes) as the main level. The base point and the measurement point may deviate due to this horizontal adjustment work, but this is adjusted by the horizontal movement mechanism of the transit.

を要するといった不都合があった。However, in the horizontal adjustment work by expanding and contracting the legs, it is necessary to repeat the expansion and contraction of the legs 22, the fixing of the clamps 28, and the confirmation of the leveler while making adjustments. In the conventional type tripod, the work of loosening the clamp 28 and extending and contracting the leg 22 is very unstable and difficult to work, so that it requires skill and work time.

があった。Further, if there is a large horizontal deviation during the horizontal adjustment work due to such troublesome expansion and contraction of the legs, after the horizontal adjustment by the leveling screw, the horizontal movement mechanism is used to set the base point and the measuring point. When correcting the deviation, there is a limit in the moving range, and in some cases it becomes impossible to correct, and there is the inconvenience that the work must be restarted from the beginning.

る。In a tripod having such an extension / contraction adjusting device 1, in order to perform horizontal adjustment by extending / contracting the legs, first, the holding bolt 5 of the extension / contraction adjusting device 1 is tightened, and then the clamp 28 is loosened. Then, the crank handle 2 is rotated while looking at the spare leveler such as the circular bubble tube of the surveying instrument placed on the leg 21. For example, when the crank handle 2 is rotated counterclockwise, the shaft 3 moves downward with respect to the expansion and contraction adjusting device 1, that is, the center rod 2 whose lower end is grounded.
7 and the shaft 3 whose lower end is supported by the end face cover 19 attached to its upper end, the expansion and contraction adjusting device 1 and the side rod 24 fixed thereto are lifted, and the legs 22 are extended as a whole. On the contrary, when the handle is rotated clockwise, the expansion and contraction adjusting device 1 is lowered and the leg 22 is shortened. In this way, the two legs 22 to which the expansion and contraction adjusting device 1 is attached are alternately expanded and contracted to perform horizontal adjustment. When the adjustment is completed, the clamp 28 is tightened and the leveling screw is used for horizontal adjustment.
The other operations are the same as those of the conventional type and will not be described.

The plate member 20 may be bolted to the upper end of the center rod 27. By doing so, the rattling of the center rod 27 can be prevented and the telescopic adjustment device 1 can be operated smoothly during the telescopic work of the legs.
