[0034] The present utility model provides a laser spirit level as Figures 1 to 3 shown, which includes an equipment housing 1. A support mechanism is provided on the lower side of the equipment housing 1. The support mechanism includes a limit groove 11, a positioning hole 12, a fixed plate 13, a positioning seat 14, an adjusting block 15, a support plate 2, a limit rod 21, a positioning rod 22, a threaded rod 23, a side support plate 24 and an anti-slip pad 25. A laser 16 is fixedly connected to the left side of the equipment housing 1. A protective cover 4 is fixedly connected to the left side surface of the equipment housing 1 at a position outside the laser 16.

[0036] Meanwhile, when in use, the laser is emitted by the laser device 16, and the laser passes through the cross beam splitter 38 or the linear beam splitter 37 to adjust the shape of the laser, and then is emitted outward through the protective mirror 41. The protective cover 4 protects the laser device 16, the cross beam splitter 38 and the linear beam splitter 37, improving its use safety.

[0037] Refer to Figure 2 、 Figure 3 and Figure 5 As shown in, the fixing plate 13 is fixedly connected to the upper surface of the device housing 1, the positioning seat 14 is fixedly connected to the middle of the fixing plate 13, the lower end of the adjusting block 15 is rotatably connected to the positioning seat 14, the limiting groove 11 is opened at the middle position of the device housing 1, the limiting rod 21 is slidably connected to the limiting groove 11, the threaded rod 23 is threadedly connected to the inside of the limiting rod 21, the upper end of the threaded rod 23 is fixedly connected to the lower end of the adjusting block 15, the lower end of the limiting rod 21 is fixedly connected to the upper surface of the support plate 2, the positioning holes 12 are respectively opened at the positions on the left and right sides of the device housing 1, the positioning rods 22 are slidably connected to the positioning holes 12, the lower ends of the positioning rods 22 are fixedly connected to the upper surface of the support plate 2, and two groups of side support plates 24 are rotatably connected to the front and rear sides of the lower surface of the support plate 2, and anti-slip pads 25 are fixedly connected to the lower surfaces of the side support plates 24.

[0038] Specifically, during the installation of the laser level, the side support plates 24 on the front and rear sides are unfolded outward, cooperate with the support plate 2 to support the laser level, and at the same time, the anti-slip pads 25 effectively improve the stability of the device. When it is necessary to adjust the height of the laser level, rotate the adjusting block 15, and the adjusting block 15 drives the threaded rod 23 to rotate. With the cooperation of the positioning rod 22 and the positioning hole 12, the threaded rod 23 pushes the limiting rod 21 downward during rotation, thereby pushing the support plate 2 downward. At this time, the height of the laser level is adjusted.

[0039] Refer to Figure 2 、 Figure 3 and Figure 4, a positioning groove 3 is provided at the lower side of the left end of the device housing 1 below the laser 16.

[0040] In addition, during the adjustment of the one-way beam splitter 37 and the cross beam splitter 38, first pull the adjusting knob 35 to the left, and then drive the plug-in block 32 to slide to the left inside the positioning groove 3 through the sliding rod 33, so that it separates from the inside of the plug-in groove 31. Then rotate the adjusting knob 35. The adjusting knob 35 drives the sliding rod 33 to rotate, and the sliding rod 33 drives the adjusting plate 36 to rotate, thereby swapping the positions of the one-way beam splitter 37 and the cross beam splitter 38. Then, after releasing the adjusting knob 35, the support spring 34 pushes the plug-in block 32 to the right, and the plug-in block 32 is reinserted into the plug-in groove 31 to position the position of the plug-in block 32, thereby maintaining the stability of the sliding rod 33 and the adjusting plate 36.
