[0026] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific implementation modes.
[0027] Embodiment 1
[0028] As Figures 1-5 shown, this embodiment includes a fixed seat 102 and a laser head 104. The fixed seat 102 is provided with a mounting hole 106 of a cylindrical structure. The laser head 104 is of a cylindrical structure, and one end thereof is used to emit a laser beam. The laser head 104 is installed in the mounting hole 106 and there is an active gap between the laser head 104 and the mounting hole 106.
[0029] In this embodiment, three mounting holes 106 are arranged on the fixed seat 102. The three mounting holes 106 form a "pin" - shaped structure. The axes of two of the mounting holes 106 are on the same straight line, and the axis of the other mounting hole 106 is perpendicular to this straight line and is located between the above - mentioned two mounting holes 106. Each mounting hole 106 is provided with a laser head 104. Its function is to be able to emit straight laser beams in three mutually perpendicular directions.
[0030] In this embodiment, a concentric annular boss 108 is provided on the outer cylindrical wall of the laser head 104. The circumferential surface of the boss 108 contacts the bottom inner wall of the mounting hole 106. The fixed seat 102 is provided with a first adjustment hole 110. The first adjustment hole 110 is communicated with the mounting hole 106 and penetrates upward through the upper surface of the fixed seat 102. The first imaginary axis of the first adjustment hole 110 eccentrically passes through the boss 108. A first adjustment rod 111 that can move along its axis and can at least partially extend downward out of the first adjustment hole 110 is further provided in the first adjustment hole 110.
[0031] In this embodiment, the fixing base 102 is provided with a second adjustment hole 112, which communicates with the mounting hole 106 and extends upward to the upper surface of the fixing base 102. A protruding structure 114 is provided at the bottom center of the inner wall of the mounting hole 106, and the protruding structure 114 contacts the outer wall of the laser head 104. A second adjustment rod 113 is also provided in the second adjustment hole 112, which can move along its axial direction and extend downward at least partially out of the second adjustment hole 112. After the second adjustment rod 113 contacts the laser head 104, it continues to move downward, which can push the laser head 104 to rotate along a second imaginary axis. The second imaginary axis passes radially through the center of the laser head 104 and the protruding structure 114. A planar recess 120 is also provided on the boss 108. When the first adjustment rod 111 contacts the boss 108, its free end abuts against the planar recess 120. In addition, in the embodiment, the bottom of the fixing base 102 is provided with a third adjustment hole 116 that penetrates its lower surface and communicates with the mounting hole 106. The protruding structure 114 is a rod-shaped structure of a third adjustment rod 118 that is installed in the third adjustment hole 116 and can move along the axial direction of the third adjustment hole 116. The top of the third adjustment rod 118 can at least partially extend into the mounting hole 106.
[0032] In this embodiment, the rotation of the laser head 104 around the axis is achieved by the first adjusting rod 111. Specifically, the first adjusting rod 111 on one side is rotated to move along its axis. The free end of the first adjusting rod 111 abuts against the planar recess 120 of the boss 108 and pushes the laser head 104 to rotate around the axis, thereby achieving the rotation of the laser head 104. Of course, the first adjusting rod 111 on the other side can also be adjusted, and its rotation direction is exactly the opposite.
[0033] The left and right swing of the laser head 104 is achieved by the second adjusting rod 113. Specifically, rotating one side of the second adjusting rod 113 causes it to move along its axial direction. The free end of the second adjusting rod 113 abuts against the laser head 104. As it continues to move, the force of the second adjusting rod 113 causes the laser head 104 to rotate around the protruding structure 114 at the bottom of the inner wall of the mounting hole 106. The rotating shaft passes radially through the center of the laser head 104 and the protruding structure 114, thereby causing the laser head 104 to swing upward.
[0034] In this embodiment, two first adjustment holes 110 are provided and symmetrically arranged along an imaginary plane passing through the axis of the laser head 104. The shortest line connecting the two first adjustment holes 110 is perpendicular to the imaginary plane, and a first adjustment rod 111 is provided in each first adjustment hole 110. Two second adjustment holes 112 are also provided and symmetrically arranged along an imaginary plane. The shortest line connecting the two second adjustment holes 112 is perpendicular to the imaginary plane, and a second adjustment rod 113 is provided in each second adjustment hole 112.
[0035] There are two first adjusting rods 111 and two second adjusting rods 113 respectively, which can realize the rotation or swing of the laser head 104 in two directions of clockwise and counterclockwise.
[0036] In this embodiment, the first adjusting hole 110, the second adjusting hole 112, and the third adjusting hole 116 are provided with internal threads, and the first adjusting rod 111, the second adjusting rod 113, and the third adjusting rod 118 are provided with external threads that are respectively in threaded fit with the first adjusting hole 110, the second adjusting hole 112, and the third adjusting hole 116. By using the threaded connection method, it can ensure the movement stroke determined by the first adjusting rod 111, the second adjusting rod 113, and the third adjusting rod 118, and can also ensure the fixation after adjustment.
[0037] Embodiment Two
[0038] This embodiment is different from Embodiment One in that the convex structure 114 is a convex block structure fixed at the bottom of the inner wall of the mounting hole 106.
[0039] Embodiment Three
[0040] In this embodiment, three mounting holes 106 are arranged on the fixed seat 102, and the three mounting holes 106 form a "pin" - shaped structure. The axes of two of the mounting holes 106 are on the same straight line, and the axis of the other mounting hole 106 is perpendicular to it and is located between the above - mentioned two mounting holes 106. Each mounting hole 106 is provided with a laser head 104. In this embodiment, by setting three laser heads 104, and the laser heads 104 emit three light rays in a "pin" - shaped manner, it meets the daily marking needs.
