Laser beam path of laser distance measure

A laser beam path device received in a laser distance measure, comprising:

• a box having a receiving unit located at a first end thereof, a first reflector received in the box and located at a second end of the box, the first reflector being inclined relative to a longitudinal axis of the box and having a hole defined centrally therethrough, the receiving unit adapted to control displacement of the laser distance measure;
• a driving unit connected to a top of the box and located above the first reflector, the driving unit having a second reflector which is located corresponding to the first reflector, an opening defined through the driving unit and located corresponding to the second reflector, the driving unit being rotatably relative to the box, and
• a laser unit connected to the box and emitting laser beams toward the first reflector, the laser beams passing through the hole of the first reflector and moving toward the second reflector which reflects the laser beams which then pass through the opening and toward an object to form an outgoing path, the laser beams being reflected by the object and reflected by the first reflector and toward to the receiving unit to form an incoming path, the receiving unit receiving the laser beams and adapted to control the displacement of the laser distance measure.
