Abstract: The utility model relates to a kind of laser straight liner, including a foundation and a base, wherein said foundation is provided with batteries and said base is provided with at least one laser projection module. Said base and said foundation are connected in the way that is 360 degrees rotatable. One side of said foundation that faces said base is provided with the anode and cathode conduction rings that can connect batteries, and one side of said base that faces said foundation is provided with two contact pieces that can connect various laser projection modules and also can touch the anode and cathode conduction rings, thus realizing the conduction-wire-free connection between said laser projection modules and said batteries. This utility model makes said laser projection modules freely rotatable on said foundation, and thus the rotated angle during marking can be accurately controlled, ingenious and reasonable in design and convenient in operation.

Abstract: A laser marking device including an oscillating mechanism that enables the laser beams emitted from the device to be emitted in either a constant state or in a pulsed state to enhance the visibility of the laser beam in various lighting conditions. The oscillating mechanism modulates the power supplied by the power source into either a constant state or a pulsed state in order to send the power in that state to the laser generator, which consequently emits a laser beam in either a constant or pulsed state. In bright light conditions in which the beam is not readily visible, the beam can be emitted in a pulsed state to be sensed by a separate detector capable of detecting the pulsed beam from the device. The detector provides an indication to the operator of the position of the beam relative to the detector such that the operator can readily determine the location of the beam.
