Abstract: A structurally improved flashlight includes a handle coupled to a main body at a bottom of the main body. The handle has a trigger assembled between a pair of housing parts. The trigger is formed with a zigzag room that is communicated with openings formed at two laterals of the trigger for accommodating a safety mechanism. A magnet provided at an upper surface of the trigger is to removably engage a reed switch installed on the flashlight main body. A spring is deposited between the trigger and the two housing parts, so as to enable the trigger to resiliently move to and fro. The trigger is for conveniently switching the flashlight among different illumination phases, such as light intensity, blinking and on/off status. The structurally improved flashlight is also designed to be held in a certain illumination phase temporarily, so as to prevent unintentional change of the set illumination phase.

Abstract: A flashlight charger includes a bottom plate provided with a pressing element and an electrically conducting part fixedly connected to a top plate that partially covers the pressing element and the electrically conducting part. A flashlight to be charged is aligned and connected with the flashlight charger and then pushed backward relative to the flashlight charger to allow the charging terminals at one end of the flashlight charger to make good electrical contact with the corresponding charging ends of the flashlight while the flashlight is securely fastened with the flashlight charger. When charging is completed, the flashlight can be removed from the flashlight charger rapidly and conveniently. The flashlight charger features good and stable electrical contact in use.

Abstract: A flashlight mount includes a clamp-type positioning element and an elongate clamping element pivotally connected to an upper section of the clamp-type positioning element. To fasten a flashlight to the mount, an engaging section on a lateral side of the flashlight is inserted into a C-shaped groove on a lateral side of a fastening extension of the elongate clamping element. Once the engaging section is inserted in the C-shaped groove to the greatest extent possible, a limiting recess at one end of the flashlight is engaged with a projection at the corresponding end of the fastening extension to fix the flashlight in position to the elongate clamping element. Then, an object to be clamped is inserted into an insertion space extending laterally into the clamp-type positioning element, before a lower screw rod is rotated upward to secure the clamp-type positioning element to the object in a clamping manner.

Abstract: Provided is an improved flashlight structure applicable to a flashlight for use at special sites. The flashlight structure includes a press switch whose protruding end is constantly received in a recessed area. Therefore, should the flashlight be dropped, with the press switch facing down, the press switch will not be pressed inward (and hence turned on or off) by accident. Also, the flashlight structure includes a partition plate for separating batteries in the flashlight and preventing the batteries from overheating due to close contact. A lighting unit connected to the open end of the flashlight structure is peripherally provided with ribs of different widths for engaging with the corresponding slots and thus positioning the lighting unit properly. An annular isolation portion in the middle section of the press switch is tightly engaged with the inner periphery of an end hole of the flashlight structure to prevent entry of external moisture.
