Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that functional, methodological, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

As shown in fig. 1-3, the invention provides a measuring instrument for civil engineering, which comprises a supporting base 1, wherein in order to facilitate the supporting and carrying of the invention, a supporting rod 3 is fixedly installed at the bottom of the supporting base 1, a rubber pad 4 is riveted at the bottom of the supporting rod 3, a through hole 2 is formed in the central position of the outer side wall of the supporting base 1, vertical rods 5 are fixedly installed at the left and right ends of the top of the supporting base 1, a rotating rod 6 is movably connected between the two vertical rods 5, a driven gear 13 is sleeved at one end of the outer wall of the rotating rod 6, a spool 7 is sleeved at the central position of the outer wall of the rotating rod 6, a vertical line 9 is wound on the outer wall of the spool 7, in order to prevent the vertical line 9 from winding out of the spool 7 in the measuring and using processes, a limiting plate 8 is fixedly connected to, the bottom spiro union of briquetting 15 has conical block 16, fixed mounting has motor 10 on the one end lateral wall of arbitrary montant 5, and motor 10 electricity connects external power source, the output fixed mounting of motor 10 has lead screw 11, lead screw 11's outer wall has cup jointed driving gear 12, and driving gear 12 is connected with driven gear 13 meshing, support about 1 top of base both ends fixed mounting have splint 14, and two splint 14 are located two montant 5 inboards, splint 14 is U type splint, every the sunken department level of splint 14's inside wall is pegged graft and is had bull stick 17, every bull stick 17's outer wall has cup jointed pulley 18, and the pulley 18 and the 15 inseparable laminating of briquetting of both sides, and pulley 18 is used for controlling the direction of conical block 16 whereabouts, is used for further perpendicular whereabouts of assurance conical block 16.
