Disclosed herein is a sunshade clip attachable to spectacles, which can allow a fragrance to be continuously emitted from a perfume injected in the spectacles and the sunshade clip for a certain long time, thereby creating a pleasant atmosphere around a wearer of the spectacles. In such spectacles comprising a pair of lens frames for retaining prescription lenses, respectively, a nose frame connecting adjacent inner ends of both the lens frames, and temple arms extended rearward from opposite outer ends of both the lens frames for allowing the spectacles to be worn on the wearer's ears, a pair of attachment units are provided for detachably attaching the sunshade clip to the spectacles. The present invention enables the fragrance to be emitted from the respective components of the spectacles and/or the sunshade clip, and/or the attachment units.

The pivotable sunshade clip comprises a spectacles bridge and a sunshade bridge which are attached to frames of spectacles and the sunshade clip, respectively. Both the bridges are made of the same material as that the frames. The spectacles bridge is centrally provided with a stator having a pair of magnets inserted at front and upper sides thereof, respectively. The sunshade bridge centrally provided with a mover. The mover is adapted be pivoted upward or downward to be magnetically attached to one of the magnets inserted in the stator, thereby maintaining the sunshade clip in an opening or closing position relative to the spectacles. Such mover includes a center stator recess for receiving the stator, and pivot bridge portions located at both sides the stator recess, respectively. Each of the pivot bridge portions has a fitting groove for allowing the spectacles bridge to be fitted therein while forming a pivot center point. The mover also includes a magnet inserted in the stator recess and adapted to be magnetically attracted to one of the magnets of the stator.

A loosening-preventing device for pipe fitting. In the device, a casing includes a semispherical member equipped with an open surface, a female screw thread disposed at one end of the semispherical member, and a finishing member disposed at the other end of the semispherical member. A locking member has a male screw thread and a head at one end of the male screw thread, so as to connect to the female screw thread of the casing. The screw clamping of the casing and the locking member prevents the pipe fitting from rotating, thereby preventing the pipe fitting from being loosened.
