Embodiment Construction
[0020] Below, in conjunction with accompanying drawing and specific embodiment, the invention is described in further detail:
[0021] refer to Figure 1-3 As shown, the laser line throwing instrument in this embodiment includes a base 1 and a rotating base 21 rotatably connected to the base 1 , and the rotating base 21 is arranged parallel to the base 1 . Manually rotate the rotating seat 21 to realize the rough adjustment of the line-throwing position, and then use the screw nut knob 9 to realize the precise adjustment of the line-throwing position. The base 1 includes an adjustment component, which can adjust the angle between the base 1 and the horizontal plane to ensure that the base 1 is parallel to the horizontal plane or forms a certain angle in a certain direction. The casing (not shown) that is connected with the swivel base 21 is provided with a battery compartment 23, and a power supply such as a lithium battery can be placed in the battery compartment 23 to provi...
