A laser module with trimming capacity has a base having an indented portion formed thereon so as to be non-annular in configuration. A lens is disposed inside the base. A laser diode is disposed inside the base and behind the lens. A printed circuit board electrically connects the laser diode. Alternatively, the base has a polygonal rotation portion, instead of the indented portion, disposed on an external surface thereof.

What is claimed is: 1. A laser module with adjustable laser beam, comprising: a hollow base having a front portion and a rear portion, and including an indented portion formed at said rear portion of said hollow base and having a non-annular configuration, said hollow base further having an internal surface and an external surface, an external threaded portion and an internal threaded portion being formed at said external and internal surfaces of said hollow base, respectively, at said front portion thereof; a front sleeve, said front sleeve including a threaded portion formed at an external surface thereof, said front sleeve being attached to said hollow base by rotative engagement between said internal threaded portion of said hollow base and said threaded portion of said first sleeve, respectively; a lens attached to said first sleeve and disposed inside the hollow base in proximity to said front portion thereof; a laser diode disposed inside the hollow base in proximity to said rear portion thereof; a printed circuit board electrically connected to the laser diode; a spring disposed within said hollow base between said lens and said laser diode; a lens holder having a threaded portion formed at an internal surface thereof, said lens holder being attached to said hollow base by rotative engagement between said external threaded portion of said hollow base and said threaded portion of said lens holder; and a prism disposed at said lens holder. 2. The laser module as claimed in claim 1, wherein the indented portion includes a recess formed on the hollow base. 3. The laser module as claimed in claim 1, wherein the indented portion includes a through hole formed in the hollow base. 4. The laser module as claimed in claim 1, wherein the lens holder is screwed to said front portion of the hollow base. 5. The laser module as claimed in claim 1, wherein the lens holder is tightly sleeved to said front portion of the hollow base. 6. The laser module as claimed in claim 1, wherein the printed circuit board is disposed outside the hollow base. 7. The laser module as claimed in claim 1, wherein the printed circuit board is disposed inside the hollow base. 8. The laser module as claimed in claim 1, wherein the hollow base includes a front base and a rear base. 9. A laser module with adjustable laser beam, comprising: a hollow base having a front portion and a rear portion, and including a polygonal rotation portion disposed on an external surface thereof, said polygonal rotation portion having a non-annular configuration, said hollow base further having an internal surface and an external surface, an external threaded portion and an internal threaded portion being formed at said external and internal surfaces of said hollow base, respectively, at said front portion thereof, a front sleeve, said front sleeve including a threaded portion formed at an external surface thereof, said front sleeve being attached to said hollow base by rotative engagement between said internal threaded portions of said hollow base and said threaded portion of said first sleeve, respectively; a lens attached to said first sleeve and disposed inside the hollow base; a laser diode disposed inside the hollow base in proximity to said rear portion thereof; a printed circuit board electrically connected to the laser diode; a spring disposed within said hollow base between said lens and said laser diode; and a lens holder having a threaded portion formed at an internal surface thereof, said lens holder being attached to said hollow base by rotative engagement between said external threaded portion of said hollow base and said threaded portion of said lens holder. 10. A laser module with adjustable laser beam, comprising: a hollow base having a front portion and a rear portion, and including a portion having a non-annular configuration and formed at said rear portion of said hollow base, said hollow base further having an internal surface and an external surface, an external threaded portion and an internal threaded portion being formed at said external and internal surfaces of said hollow base, respectively, at said front portion thereof; a front sleeve, said front sleeve including a threaded portion formed at an external surface thereof, said front sleeve being attached to said hollow base by rotative engagement between said internal threaded portion of said hollow base and said threaded portion of said first sleeve, respectively; a lens attached to said first sleeve and disposed inside the hollow base in proximity to said front portion thereof; a laser diode disposed inside the hollow base in proximity to said rear portion thereof; a printed circuit board electrically connected to the laser diode; a spring disposed within said hollow base between said lens and said laser diode; a lens holder having a threaded portion formed at an internal surface thereof, said lens holder being attached to said hollow base by rotative engagement between said external threaded portion of said hollow base and said threaded portion of said lens holder; and a prism disposed at said lens holder, wherein a relative disposition between said laser diode and said lens is adjusted by rotative motion of said front sleeve relative to said hollow base, and wherein a relative disposition between said laser diode and said prism is adjusted by rotative motion of said hollow base relative to said lens holder. 11. The laser module as claimed in claim 10, wherein said portion of non-annular configuration includes an indented portion. 12. The laser module as claimed in claim 10, wherein said portion of non-annular configuration includes a polygonal rotation portion.
