In the utility model, described beam switching device is lens or catoptron.Adopt lens or catoptron all can realize the purpose of this utility model.
In the utility model, be provided with a planet gearing in the described kinematic train.Utilize this planetary driving device, can make the gyration of scanner revolving shaft be stabilized in two kinds of duties that reach less than 8 rev/mins greater than 300 rev/mins.When the scanner revolving shaft with greater than 300 rev/mins speed operation the time, it can form a continuous laser scanning line on object; When the scanner revolving shaft with less than 8 rev/mins speed operation the time, it can form the bright laser short-term that moves at a slow speed on object.
In the utility model, described control circuit board is provided with the remote-receiver that can carry out open and close and the control of revolving shaft rotating speed to Geoplane.Utilize this remote-receiver, can carry out the rotating speed control of open and close and revolving shaft at a distance to scanner, therefore at the scanner revolving shaft with less than 8 rev/mins rotary speed working the time, it can make the bright laser short-term of doing to move at a slow speed on object rest on selected arbitrarily position.
In the utility model, the bottom of described housing is connected with a platform, and described platform is provided with level and determines device.Utilize level to determine device can determine whether platform is in the correct working position of setting, thereby make the scanner revolving shaft can scan the horizontal laser light line of an annular.
In the utility model, the bottom of described platform is provided with level adjustment system.Utilize this level adjustment system can regulate the angle of inclination on platform and ground, thereby make the utility model when the bigger occasion of the terrain slope gradient is used, also can make platform be in correct working position, make the scanner revolving shaft can scan the horizontal laser light line of an annular.
