  • Patent number: 11009315
    Abstract: A laser target pointer comprises a case, a lighting module, a laser module, an operating module, an adjustment mechanism and a magnetic switch. The adjustment mechanism is equipped with a biaxial pivoting mechanism to adjust the position of the laser aiming point of the laser module. The magnetic switch can be magnetically attracted and detachably connected with a contact block and electrically connected to the laser target pointer. The power of the laser target pointer can be conveniently turned on or off by operating the magnetic switch. The lighting module comprises a plurality of invisible light emitting diodes having different divergence angles in order to provide different irradiation distances. The operating module comprises a plurality of luminous patterns each corresponding to an operation function, such that the user can clearly and quickly identify which one of the operation functions is currently enabled.

  • Patent number: 10107592
    Abstract: A laser target pointer for engaging a gun includes a body, a locating plate, a positioning block, a first fitting element and an adjustable positioning assembly. By providing the adjustable positioning assembly, the laser target pointer can be clamped to a gun with an arbitrary body width. By adjusting a position of the positioning block with respect to the locating plate, the laser target pointer can be positioned to a gun with an arbitrary transverse positioning groove. Thus, the laser target pointer can be properly assembled to any gun body having specifications within a predetermined range, and the position of the laser target pointer can be adjusted on the gun body in the extension direction, such that a single laser target pointer can be applicable to various guns with different brands, types, series or specifications.

  • Publication number: 20150276352
    Abstract: The present invention provides an improved structure of laser sight, which comprises a sight body, a block, a displacement adjusting device, and a switch. The block can be disposed flexibly to locations on one side of the sight body for fitting different type of firearms. The displacement adjusting device can control the location of a laser module inside the laser sight for changing the location of light emission of the laser module and modifying the location of the laser module. The switch is used for controlling the laser module and improving the convenience in control. By using the structure described above, the laser sight will have better practicability and sighting performance.

  • Publication number: 20070176515
    Abstract: A piezoelectric linear motor apparatus and method is provided. The apparatus comprises a carriage configured to be actuated and a stator configured to actuate the carriage. The stator comprises a meander line structure and a gear teeth structure, coupled to the top of the meander line structure and a contact layer underneath the carriage. Furthermore, the meander line structure comprises a series of bimorph actuators laid linearly in the meander line structure. Each pair of neighboring bimorph actuators being linked with a corresponding connector on both sides of top and bottom. The meander line structure also comprises an odd series of connectors and an even series of connectors, interleaved with each individual connector, applied with phase-splitter's alternating current (AC) power to deform the bimorph actuators for generating traveling wave. The gear teeth structure is configured to transport traveling wave from the meander line structure to the carriage.
