[0046] During the measurement process, the light intensity is self-adaptively adjusted: the light sensor 27 in the installation groove 26 collects the external light intensity data in real time and transmits the signal to the control panel 14; the control panel 14 drives the gear of the aperture blade 25 of the main laser light point device 22 to rotate according to the light data, and adjusts the aperture opening degree; in strong light environment, the aperture is reduced to enhance the concentration of the main laser light, and to avoid the influence of the scattered light on the point accuracy; in weak light environment, the aperture is enlarged to widen the laser irradiation range, and to ensure that the measurement point is clear and identifiable.

[0047] In addition, the storage box 42 on the installation support 41 can adjust the internal space through the sliding partition plate 45, adapt to the storage of different specifications of measurement accessories, the rubber pad 46 increases the friction force between the partition plate 45 and the guide rail 44, prevents the sliding of the partition plate 45 during the storage of the accessories, and improves the convenience of the device.
