Is provided.

As shown in FIGS. 3 and 4, a rectangular level part 12 provided near the upper end of the level rod 10 is leveled by one positioning elastic piece 15 and one fixing plate 16. The positioning elastic piece 15 is placed in a recess 17 provided at the center, the positioning elastic piece 15 is placed at the bottom of the recess 17, the level component 12 is placed on the positioning elastic piece 15, and a window hole 18 is further provided at the center. The fixing plate 16 has a bottom portion in contact with the upper surface of the level component 12, and a window 18 is provided at a position corresponding to the level component 12. When an error occurs after attaching to the level component 12 or after using for a certain period of time, only two screws 19 are loosened or tightened to adjust the elastic support state of the level component 12 by the positioning elastic piece 15 to level the level component 12. Can be achieved. After the horizontal component 12 is adjusted horizontally, the two screws 19 may be fixed with a screw fixing adhesive or a flash adhesive.

The laser device 11 includes one laser head 20, one battery box 21 and one fixing plate 22, and the light beam projected by the laser head 20 is point-like or vertical or horizontal linear. The laser device 11 is classified into two different standards, a point laser device and a horizontal or vertical linear laser device, and the laser head 20 is a circular laser head at both ends of the level rod 10. The laser head 20 is mounted in the fixing hole 23 (see FIGS. 5 and 6), and the front and rear and upper and lower sides of the laser head 20 are fixed in the laser head fixing hole 23 by screws 24, and the tightening of these screws 24 is adjusted. The direction of the optical axis of the laser head 20 can be adjusted, thereby reducing errors to a minimum. An electric circuit board (not shown in the figure) is provided inside the laser head 20, and the laser head 20 is connected to the battery box 21 through a conductor 25, and a switch 26 is provided on the battery box 21. The battery box 21 is fixed in a battery box fixing hole 27 near both ends of the level rod 10, and the fixing plate 22 includes a plurality of screws 28. The projection hole 29 is fixed to both ends of the level rod 10 at positions opposite to the laser head 20 of the fixing plate 22, and the projection hole 29 projects light emitted from the laser head 20 to the outside. Used for

FIG. 7 is a view showing a use state of the present invention. The level of the present invention can be used by installing it on the rotating sheet 31 of the tripod 30. According to the present invention, horizontal and other angles can be measured by the level components 12, 13, and 14 on the level, and a point or vertical or horizontal line can be measured by a point or line laser device installed at both ends. The marking can be projected, so the present invention can be used for surveying horizontal, head or vertical lines at building construction sites, and can provide the effect of quick surveying, which is convenient.
