Abstract:
An adjusting device for adjusting a projecting direction of a view, comprising:a body case formed by an upper cover and a lower cover; a reflector being pivotally installed in the body case; the body case is formed with an incident hole, a first viewing hole and a second viewing hole; the incident hole serving for receiving an outer view a user can see the received view from the first viewing hole and the second viewing hole; a viewing direction of the first viewing hole being identical to the incident direction of the outer view; a viewing direction of the second viewing hole being perpendicular to the incident direction of the outer view; one lateral side of the reflector having a surface which has a guide groove along the edge thereof; and an adjusting button being located on the upper cover; a rotary flange being installed on the adjusting button; a rotary arm being adhered on the adjusting button; one end of the rotary arm being fixed to a center of the adjusting button, and another end thereof being installed with a guide block; the guide block being pivotally installed to the guide groove and being movable in the guide groove; whereby when a user desires to see an outer view; by applying a force to the rotary flange to drive the rotary arm; the guide block will move in the guide groove and then drive the reflector to rotate to a predetermined angle; on the contrary, when the user desires to see outer view from the first viewing hole; the user only needs to restore the adjusting button to the original position so that the reflector will not block the incident direction of the light of the view; wherein said adjusting device further comprises a lens installed on the second viewing hole; a handle being a hollow case with an objective lens set therein; one end of the handle being connected to the first objective hole and another end thereof serves for being viewed by the user; a telescopic rod having one end being connected to an incident hole and another end thereof being connected to a projecting of the second adjusting device for adjusting the respective position of the two adjusting devices; the second adjusting device includes the following components; a second body case being formed by a second upper cover and a second lower cover; a second reflector being pivotally installed in the second body case; the second body case being formed with an projecting hole, a first objective hole and a second objective hole for receiving outer view; the viewing direction of the first objective hole is identical to the projecting direction of the view projecting to the projecting hole; an objective lens being placed in the hole; a receiving direction of the second objective hole being perpendicular to a projecting direction of the projecting hole; and a lens being placed in the hole; the second reflector being placed in and pivotally connected to the second body case; an edge of one surface of the second reflector having a second guide groove; and a second adjusting button being located on the upper cover; a rotary flange being installed on the adjusting button; thereby the user rotating the adjusting button; a rotary arm being adhered on the adjusting button; one end of the rotary arm being fixed to a center of the adjusting button, and another end thereof is installed with a guide block; the guide block being pivotally installed to the guide groove and being movable in the guide groove; whereby when a user desires to see an outer view projecting to the second objective hole; by applying a force to the second rotary flange to drive the second rotary arm; the second guide block will move in the second guide groove and then drive the second reflector to rotate to a second predetermined angle; on the contrary, when the user desires to see outer view from the first viewing hole; the user only needs to restore the adjusting button to an original position so that the second reflector will not block the incident direction of the light of the view; thus a device having a function of a telescope and a periscope is achieved.
