     As shown in  FIGS. 1A to 1C ,  FIG. 2A  and.  FIG. 2B , in a preferred embodiment of the present invention, the laser target pointer  1  comprises: a case  10 , a laser module  20 , a lighting module  30 , a magnetic switch with connecting cable  50 , a power module  60 , an operating module (unnumbered), and an adjustment mechanism  14 . 
     The case  10  comprises: a main body  11 , a lower cover  1 . 2  and a front cover  13 . The lower cover  12  is assembled and fixed under the main body  11 , while the front cover  13  is connected to a front side of the main body  11  in a detachable manner. The power module  60  comprises at least a battery and is received inside the main body  11 . The front cover  13  is locked to the front side of the main body  11  by a clipping mechanism  131 . When the clipping mechanism  131  is unlocked, the front cover  13  can be detached from the main body  11  in order to expose the at least one battery (power module  60 ) located in the main body  11  for battery replacement. The laser module  20  and the adjustment mechanism  14  are located in the lower cover  12 , and are electrically connected to the power module  60  through an top-pressing circuit board  40 . The top-pressing circuit board  40  is provided with various electronic components for controlling the laser target pointer  1 . The laser target pointer  1  further comprises an adjustable fixing rack  15  disposed on a top surface of the main body  11 . The fixing rack  15  is for mounting the laser target pointer  1  onto a carrier in a detachable manner. The carrier can be, but not limited to, a pistols, rifle, paintball gun, air gun or other carrier that can be connected by the fixing rack  15 . Since the front cover  13  is opened from the front side of the case  10  to replace the battery, even when the laser target pointer  1  of the present invention is mounted on a carrier (such like a pistol  91  shown in  FIG. 7A ), the front cover  13  can still be opened for replacing the battery without the need to remove the laser target pointer  1  from the carrier first, which is very convenient for battery replacement. 
     The lighting module  30  is located in the case  10  and comprises at least one light emitting element  31 ,  32 , and can emit illumination light forwardly out from the case  10 . The laser module  20  is located inside the lower cover  12  of the case  10  and comprises at least one laser unit  22 , and can emit laser beam forwardly out from the case  10 . The power module  60  is located within the main body  11  of the case  10  and is electrically connected to the lighting module  30  and the laser module  20  to provide electric power to the at least one light emitting element  31 ,  32  and the at least one laser unit  22 . The operating module is electrically connected to the power module  60 . The operating module comprises at least one button  61  which can be pressed by user in order to operate the power switch and other functions of the laser target pointer  1 . 
     As shown in  FIG. 3A  and  FIG. 3B , the adjustment mechanism  14  is connected with the laser module  20 , and can be used for adjusting the position of the laser aiming point of laser beam emitted by the at least one laser unit  22  of the laser module  20 . In this embodiment, the adjustment mechanism  14  comprises: a biaxial pivoting mechanism  24 , a first adjusting screw set and a second adjusting screw set. One side surface of the laser module  20  is pivotally coupled to the biaxial pivoting mechanism  24 , such that the laser module  20  can use the biaxial pivoting mechanism  24  as a pivot to perform biaxial pivoting movements according to a first axis and a second axis. The first adjusting screw set is disposed on the side surface of the laser module  20  in such a manner that, by rotating the first adjusting screw set, the side surface of the laser module  20  will be pushed by the first adjusting screw set to rotate around the first axis using the biaxial pivoting mechanism  24  as a pivot. In addition, the second adjusting screw set is disposed on a bottom surface of the laser module  20  in such a manner that, by rotating the second adjusting screw set, the bottom surface of the laser module  20  will be pushed by the second adjusting screw set to rotate around the second axis using the biaxial pivoting mechanism  24  as a pivot. Therefore, by rotating the first adjusting screw set and the second adjusting screw set, the laser module  20  can perform biaxial pivoting movements using the biaxial pivoting mechanism  24  as a pivot, so as to adjust the position of the laser aiming point of the laser beam emitted by the at least one laser unit  22 , and thus calibrate the aiming accuracy of the laser beam as well as the bullet flight path when the gun is shooting. 
     As shown in  FIG. 3C , in this embodiment, the biaxial pivoting mechanism  24  comprises: a fixed axis  241   a  and a sleeve axis  242   b . The fixed axis  241   a  extends along a first direction and is fixed in the lower cover  12  of the case  10 . The sleeve axis  242   b  has a through hole extending in the first direction and a shaft portion extending in a second direction, wherein the second direction is perpendicular to the first direction. The through hole of the sleeve axis  242   b  is sleeved on the fixed axis  241   a  in a pivotable manner, so that the sleeve axis  242   b  can perform the pivoting movement around the first axis about the fixed axis  241   a.  The side surface of the laser module  20  is pivotally coupled to the shaft portion of the sleeve axis  242   b,  so that the laser module  20  can perform the pivoting movement around the second axis about the shaft portion of the sleeve axis  242   b.  In this embodiment, a shaft hole is provided on the side surface of the laser module  20 . The shaft portion of the sleeve axis  242   b  passes through the shaft hole from inside to outside so that the shaft portion and the through hole are exposed outside the side surface of the laser module  20 , such that the fixed axis  241   a  penetrates into the through hole of the sleeve axis  242   b  along the first direction, in addition, it also allows the laser module  20  to pivot around the second axis by using the shaft portion of the sleeve axis  242   b  as the pivot. 
     As shown in  FIG. 3A  and  FIG. 3B , the first adjusting screw set comprises a first screw  141   a,  a first pushing block  142   a  and a first fixing ring  143   a.  By rotating the first screw  141   a,  the first pushing block  142   a  can be driven to push the side surface of the laser module  20  in order to cause the laser module  20  together with the sleeve axis  242   b  to pivot around the first axis by using the fixed axis  241   a  as the pivot. The first screw  141   a  has an internal thread which is screwed with the outer thread of the first pushing block  142   a,  therefore, when the first pushing block  142   a  cannot be rotated due to restriction of the flat bottom groove  211 , and there is an external force tending to rotate the first screw  141   a,  the rotational movement of the first screw  141   a  will drive the first pushing block  142   a  to move linearly along the axial direction of its thread. The first fixing ring  143   a  is used to position the first screw  141   a  on the first screw hole  123  on the side surface of the laser module  20 , such that, when the first screw  141   a  is rotated by an external force, the first screw  141   a  will be positioned and restricted by the first fixing ring  143   a  and can only perform a simple rotary motion without displacement forward and backward along its axial direction. The second adjusting screw set comprises a second screw  141   b,  a second pushing block  142   b  and a second fixing ring  143   b.  By rotating the second screw  141   b,  the second pushing block  142   b  can be driven to push the bottom surface of the laser module  20  in order to cause the laser module  20  to pivot around the second axis by using the shaft portion of the sleeve axis  242   b  as the pivot. The second screw  141   b  has an internal thread which is screwed with the outer thread of the second pushing block  142   b,  therefore, when the second pushing block  142   b  cannot be rotated due to restriction of another flat bottom groove (not shown in figures), and there is an external force tending to rotate the second screw  141   b,  the rotational movement of the second screw  141   b  will drive the second pushing block  142   b  to move linearly along the axial direction of its thread. The second fixing ring  143   b  is used to position the second screw  141   b  on the second screw hole (not shown in figures) on the bottom surface of the laser module  20 , such that, when the second screw  141   b  is rotated by an external force, the second screw  141   b  will be positioned and restricted by the second fixing ring  143   b  and can only perform a simple rotary motion without displacement forward and backward along its axial direction. The adjustment mechanism  14  further comprises at least one position retaining element  25   a,    25   b,  which respectively abuts between the other side surface and the top surface of the laser module  20  and the case  10 . In this embodiment, the position retaining elements  25   a ,  25   b  are conical coil springs, which can provide elastic pushing forces to the other side surface and the top surface of the laser module  20 ; that is, the position retaining elements  25   a,    25   b  can provide elastic pushing forces to the laser module  20 , so that the first pushing block  142   a  and the second pushing block  142   b  can keep pressing against the laser module  20 , such that, when the first screw  141   a  and the second screw  141   b  stop rotating by external forces, the position of the laser module  20  can be maintained by the elastic pushing forces of the position retaining elements  25   a,    25   b.  Furthermore, a flat bottom groove  211  extending along the first direction is formed on the side surface of the laser module  20 , in addition, the first pushing block  142   a  has a square shape with a width substantially matching the width of the flat bottom groove  211 . The first pushing block  142   a  is located in the flat bottom groove  211  and abuts against the flat bottom groove  211 ; such that, when the first screw  141   a  is rotated by an external force, the first pushing block  142   a  cannot be rotated due to the flat bottom groove  211 . Therefore, the rotational movement of the first screw  141   a  can be converted into a linear displacement of the first pushing block  142   a  along the axial direction of its thread, so as to achieve the purpose of pushing the laser module  20  to adjust the position of its laser aiming point. Similarly, the bottom surface of the laser module  20  also has a flat bottom groove (not shown in figures) extending in the second direction to restrict the second pushing block  142   b  from rotating. It can be understood from the above descriptions that, the biaxial pivoting mechanism  24  of the invention not only has the advantages of simple structure and easy assembly, but also is very simple in adjusting the position of the laser aiming point of the laser beam emitted by the laser module  20 ; it does have improved the shortcomings of the prior art laser modules whose position adjustment mechanism is complicated in structure and difficult in assembly. 
     As shown in  FIG. 4  in companion with  FIG. 2A , in this embodiment, the magnetic switch with connecting cable  50  of the laser target pointer  1  is magnetically and detachably connected to a contact block  124  provided on a rear side of the lower cover  12  of the case  10  and is further electrically connected to the top-pressing circuit board  40 . The magnetic switch with connecting cable  50  comprises: a magnetic attraction head  51 , an operation box  52  and a connecting cable  53  extending and connecting between the magnetic attraction head  51  and the operating box  52 . The contact block  124  is located in the lower cover  12  and comprises: a hollow outer ring sleeve  512  fixed in the contact block  124 , a ring magnet  513  fixed in the outer ring sleeve  512 , a spacer  514  having a small hole in the center, and a conductive post  515  inserted into the small hole of the spacer  514  and having a front end of the conductive post  515  to protrude out of the spacer  514 . The spacer  514  has a non-conductive inner ring portion  5141  adjacent to the small hole, and an electrically and magnetically conductive metal outer ring portion  5142  surrounding the inner ring portion  5141 . The outer ring portion  5142  of the spacer  514  is attracted by the magnetic force of the ring magnet  513  and contacts the ring magnet  513  in order to provide an electric conducting function. An operation button  521  is provided on a top surface of the operation box  52 ; in addition, a Velcro tape  522  (which can be one of a hook surface or a loop surface) is provided on a bottom surface of the operation box  52 . The magnetic attraction head  51  has a container structure furnished with electrically and magnetically conductive components therein. When the magnetic attraction head  51  of the magnetic switch with connecting cable  50  is magnetically attracted by the ring magnet  513  and combined with the contact block  124 , a control signal can be generated and transmitted to the top-pressing circuit board  40  by pressing the button  521  on the operation box  52 , in order to perform the operation of turning on or off the power supply of the laser target pointer  1  or activating a function selected in advance. The power or function switch for controlling the laser target pointer  1  can be extended away from the body of the laser target pointer  1  and closer to the user&#39;s hand by the connecting cable  53  and the operation box  52  of the magnetic switch with connecting cable  50 , which allows the user to conveniently press the button  521  on the operation box  52  to operate and activate the power or other pre-selected function of the laser target pointer  1 . In other words, according to the user&#39;s own operating habits, the carrier (for example, the rifle  92  shown in  FIG. 7B ) can be selectively pre-bundled with another Velcro tape at a position close to the hand grip (or at a position convenient for the user to operate); and then, the body of the laser target pointer  1  can be assembled at the front end of the rifle  92  near the barrel, while the operation box  52  of the magnetic switch with connecting cable  50  can be bonded to the “another Velcro tape” pre-bundled close to the hand grip of the carrier by using the Velcro tape  522  provided on the bottom surface of the operation box  52 . And then, the magnetic attraction head  5 , 1  of the magnetic switch with connecting cable  50  can be magnetically attached to the contact block  124  of the laser target pointer  1 . In this way, the user can easily and conveniently press the button  521  on the operation box  52  with a finger (such as a thumb) without moving his/her palm originally held on the hand grip of the carrier, so as to operate and activate the power or other pre-selected function of the laser target pointer  1 . It can be understood from the above description that, in the laser target pointer  1  of the present invention, the operation box  52  of the magnetic switch with connecting cable  50  can be attached on various locations of the carrier (any location convenient for the user to operate) by placing; such that, the power or pre-selected function of the laser target pointer  1  can be conveniently turned on and off by operating the button  521  on the operation box  52 , and thus has improved the shortcomings of the inconvenient operations of the function buttons and/or power switches of the laser target pointer of the prior art. 
     As shown in  FIG. 1A ,  FIG. 1C ,  FIG. 2A , and in companion with  FIG. 3A , in this embodiment of the laser target pointer  1  of the present invention, the laser units  22  of the laser module  20  includes a visible-light laser diode  221  and an invisible-light laser diode  222  used for emitting visible laser beam and invisible laser beam respectively, in which, the laser beams are emitted out of the case  10  through the small holes  121  on the front side of the lower cover  12 . The rear ends of the visible-light laser diode  221  and the invisible-light laser diode  222  respectively have a plurality of conductive pins  2211 ,  2221  which are soldered to a connecting circuit board  23  located on the rear side of the laser module  20 , and then electrically connected to the top-pressing circuit board  40  via the connecting circuit board  23 . When the user wishes to see the aiming point marked by the laser beam emitted by the laser module  20  with naked eyes, the user can select and enable the visible-light laser diode  221  to emit visible laser beam. When the user is wearing night vision goggles and hopes that the laser beam and its aiming point emitted by the laser module  20  can only be seen through the night vision goggles and cannot be seen by naked eyes, then the function of invisible-light laser diode  222  can be selected and turned on in order to emit invisible laser beam (for example, but not limited to: infrared laser beam). 
     The at least one light emitting element  31 ,  32  of the lighting module  30  includes a visible light emitting diode (light emitting element  31 ) and a plurality of invisible light emitting diodes (light emitting elements  32 ). The visible light emitting diode (light emitting element  31 ) is located on the front cover  13  and is used to emit visible illumination light of greater power. The plurality of invisible light emitting diodes (light emitting elements  32 ) are respectively located on the lower cover  12  and the front cover  13  and are used to emit invisible illumination light. When the user wishes to see the objects illuminated by the illumination light emitted by the lighting module  30  with his/her naked eyes, he/she can select and turn on the function of visible light illumination emitted by the visible light emitting diode (light emitting element  31 ). When the user is wearing night vision goggles and hopes that the objects illuminated by the lighting module  30  can only be seen through the night vision goggles and cannot be seen by naked eyes, then the function of invisible light emitting diodes (light emitting elements  32 ) can be selected and turned on in order to emit invisible illumination light (for example, but not limited to: infrared illumination light). It is well known in the art that, when the angle of divergence of the illuminating light is greater, then the range of illumination that can be clearly illuminated will be wider, but the distance of clear illumination will be shorter. Vice versa, when the angle of divergence of the illuminating light is smaller, then the range of illumination that can be clearly illuminated will be narrower, but the distance of clear illumination will be longer. Because in the conventional technology of laser target pointer, one or several invisible light emitting diodes (light-emitting elements) having the same divergence angle are used to provide invisible illumination light, such that the conventional laser target pointer can only choose between a wide range of short-distance illumination capability or a long-distance but narrow-range illumination capability; it is impossible for the conventional laser target pointer to provide both the wide range illumination and the long-distance illumination capabilities. In contrast, in the present invention, the divergence angles of the invisible illumination light emitted by the plurality of invisible light emitting diodes (light emitting elements  32 ) are different. Therefore, it can meet the lighting requirements of different illumination distances and divergent angles, so as to achieve the advantages of both wide-range and long-distance illumination capabilities. As shown in  FIG. 5 , the divergence angles of the invisible illumination light emitted by the four invisible light emitting diodes (light emitting elements  32 ) in the lighting module  30  of the laser target pointer  1  of the present creation are different from each other, for example, but not limited to: 7-8 degrees, 15 degrees, 30 degrees, and 60 degrees. The effective illumination range and distance of the invisible illumination light emitted by each invisible light emitting diode (light emitting element  32 ) are represented by the illumination ranges  3201 ,  3202 ,  3203 , and  3204 , respectively. That is, two of the invisible light emitting diodes (light emitting elements  32 ) with light divergence angles of 7 to 8 degrees and 15 degrees are for providing invisible illumination light at longer distances and narrower ranges; in the meantime, the other two invisible light emitting diodes (light emitting elements  32 ) with light divergence angles of 30 degrees and 60 degrees are used to provide invisible illumination light at shorter distances but wider ranges. It can be seen from  FIG. 5  that, the laser target pointer of the present invention provides a plurality of invisible light emitting diodes; the divergence angles of the invisible illumination light emitted by the invisible light emitting diodes are different from each other, so as to meet the lighting requirements of different irradiation distances and ranges, and thus has improved the shortcomings of the restricted illumination distance or range of the laser target pointer of the prior art. 
     As shown in  FIG. 6A  and  FIG. 6B , in this embodiment of the laser target pointer  1  of the present invention, the operating module is electrically connected to the top-pressing circuit board  40  and includes: a plurality of buttons  61  and a plurality of patterns  70  which can be switched between a luminous status and a darkness status. Each of the patterns  70  corresponds to at least one operation function. By pressing one or more buttons  61 , one or some of the patterns  70  will be switched to the luminous status for emitting light of a predetermined color in order to identify which operation function or functions of the laser target pointer  1  are currently enabled. Wherein, at least some of the patterns  70  can emit at least two different colors of light, so that a single pattern  70  can be used to identify at least two different operation functions. In this embodiment, the plurality of buttons  61  are provided on the lower cover  12 . The plurality of patterns  70  are arranged on a back cover of the main body  11  and comprise: an illumination pattern  71 , a lasing pattern  72 , a power-on pattern  73  (FIRE), and an invisible light pattern  74  (ILLU). In which, when the visible light operation is selected, the bright white light of the illumination pattern  71  indicates that a visible light illumination function of the lighting module  30  is selected. The green light of the laser pattern  72  indicates that a visible laser function of the laser module  20  is selected. Both the visible light illumination function and the visible light laser function can be selected independently, or both can be selected at the same time. When performing invisible light operation selections, the red light of the invisible light pattern  74  indicates that an invisible light illumination function of the lighting module  30  is selected. The orange light of the laser pattern  72  indicates that an invisible laser function of the laser module  20  is selected. Both the invisible light illumination function and the invisible light laser function can be selected independently, or both can be selected at the same time. The visible light illumination function and the invisible light illumination function cannot be selected at the same time; in addition, the visible laser function and the invisible laser function cannot be selected at the same time. When the power-on pattern  73  lights up in blue, it means that the selected function(s) is/are being activated. In this embodiment, the operation of pressing the button  521  on the operation box  52  of the magnetic switch with connecting cable  50  is used to control (turn on or off) the blue light of the power-on pattern  73 , that is, to control whether the selected function is activated or not. Wherein, two sets of the patterns  70  are respectively provided on the left half and the right half of the back cover, in addition, two sets of buttons  61  are respectively provided on the left half and the right half of the lower cover  12 . In this way, different users with a left-handed gun and a right-handed gun can conveniently operate the buttons  61  and view the plurality of patterns  70 , which does improve the shortcoming of the poor visibility of the function menu of the laser target pointer of the prior art. 
       FIGS. 7A and 7B  are schematic drawings respectively showing the laser target pointer of the present invention being equipped on a pistol and a rifle. It can be seen from  FIG. 7A  that, when the laser target pointer  1  of the present invention is assembled on a pistol  91  or other short gun, the back cover part of the main body  11  of the laser target pointer  1  will be very close to the trigger of the pistol. For conventional laser target pointers in the arts, the back cover of the laser target pointer is used to be opened for replacing the battery; therefore, conventional laser target pointers cannot replace the battery when they are installed on the pistol. Instead, the conventional laser target pointers must be removed from the pistol before the battery can be replaced, which is very inconvenient. In contrast, since the laser target pointer  1  of the present invention is to replace the battery by opening the front cover  13  from the front side of the case  10 , therefore, even if the laser target pointer  1  of the present invention is mounted on the pistol  91  as shown in  FIG. 7A , the battery (power module  60 ) can still be replaced by directly opening the front cover  13  without the need to remove the laser target pointer  1  first, and thus is very convenient. Moreover, it can be seen from  FIG. 7B  that, when the laser target pointer  1  of the present invention is assembled on a rifle  92  or other long guns, the location of the laser target pointer  1  will be far away from another location where the user generally holds the rifle/gun (such as the grip), and thus is inconvenient for the user to directly operate the buttons  61  furnished on the case  10  of the laser target pointer  1 . In contrast, since the laser target pointer  1  of the present invention includes a novel magnetic switch with connecting cable  50  whose operation box  52  can be placed at any desirable position of the carrier (rifle  92 ), for example, but not limited to, the grip or any other user-friendly position as shown in  FIG. 7B , the user can press the button  521  on the operation box  52  to switch on or off the power of the laser target pointer or other pre-selected functions without releasing his/her hand from the grip of the carrier (rifle  92 ), which does improve the shortcoming of the inconvenient operation of the function buttons and switches of the laser target pointer of the prior art. 
     While the present invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be without departing from the spirit and scope of the present invention.
