[0046] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the three-dimensional structure of the laser processing equipment in one embodiment of the present application; Figure 2 is a schematic diagram of a partial disassembly of Figure 1.

[0047] For ease of description, the front-to-back direction of the laser processing device 10 shown in FIG1 is defined as the Y-axis direction, the left-to-right direction is defined as the X-axis direction, and the height direction is defined as the Z-axis direction. The directional terms such as "top", "bottom", "left", and "right" mentioned in the embodiment of the present application when describing the laser processing device 10 are described based on the directional terms shown in FIG1 of the accompanying drawings of the specification, with the direction facing the positive Z-axis as "top", the direction facing the negative Z-axis as "bottom", the direction facing the negative Y-axis as "front", the direction facing the negative Y-axis as "back", the direction facing the negative X-axis as "left", and the direction facing the positive X-axis as "right". They do not constitute a limitation on the actual application scenario of the laser processing device 10.

[0048] The laser processing device 10 is a desktop laser processing device. It is understood that in other embodiments, the laser processing device 10 may also be an industrial laser processing device. The laser processing device 10 can engrave or cut a desired shape on a workpiece on a processing plane. The processing plane is a horizontal plane, i.e., a plane formed by the X-axis and Y-axis in a coordinate system with a horizontality of zero. The laser processing device 10 includes a laser emitting device 110 having an emitting end 11 for emitting laser light.

[0049] In some embodiments, as shown in Figures 1 and 2, the laser processing apparatus 10 further includes a visible light generator 13 and a fine-tuning mechanism 14. The visible light generator 13 is spaced apart from the output end 11 of the laser output device 110. The visible light generator 13 is connected to the fine-tuning mechanism 14. The fine-tuning mechanism 14 is capable of adjusting the light output angle of the visible light emitter 13.

[0050] In some embodiments, the visible light generator 13 , the fine-tuning mechanism 14 , and the laser emitting device 110 are connected in sequence, and the fine-tuning mechanism 14 is disposed between the visible light generator 13 and the laser emitting device 110 .

[0051] Thus, in the present application, the fine-tuning mechanism 14 can adjust the light emission direction of the visible light emitter 13 so that the light emission direction of the visible light beam emitted by the visible light generator 13 is parallel to the light emission direction of the processing laser beam emitted by the laser emitting device 110. Furthermore, a positioning spot is first struck on the surface of the workpiece to be processed by the visible light beam emitted by the visible light generator 13. The location of the positioning spot is the predetermined processing position. The operator can use the positioning spot to determine whether the predetermined processing position on the workpiece to be processed is accurately positioned. Then, the laser emitting device 110 is translated a predetermined distance to the actual processing position. The predetermined distance is the distance between the processing laser beam and the visible light beam. Since the light emission direction of the visible light beam of the visible light generator 13 is parallel to the light emission direction of the processing laser beam emitted by the laser emitting device 110, the predetermined processing position positioned by the visible light beam of the visible light generator 13 can accurately locate the actual processing position of the laser emitting device 110, thereby improving the positioning accuracy of the laser processing. Moreover, the predetermined processing position is positioned by the visible light beam emitted by the visible light generator 13, and the actual processing position of the processing laser beam can be made explicit through the predetermined processing position displayed by the visible light beam.

[0052] In some embodiments, as shown in FIG10 , the laser processing apparatus 10 further includes a track assembly 15 . A laser emitting device 110 is movably connected to the track assembly 15 to move and emit laser light to perform laser processing on a workpiece. The laser emitting device 110 includes a housing 111 , a support portion 12 connected to the housing 111 and extending from one side of the housing. A visible light generator 13 is mounted on the support portion 12 via a fine-tuning mechanism 14 . The emission port 11 is mounted on the support portion 12 via the housing 111 .

[0053] Therefore, the visible light generator 13 is mounted on the support portion 12 together with the laser emitting device 110 , and thus the visible light generator 13 moves along with the movement of the laser emitting device 110 .

[0054] 2 , the support portion 12 is horizontally disposed with its length along the X-axis and its width along the Y-axis. The visible light generator 13 is located on a side of the support portion 12 away from the emission end 11 .

[0055] In some specific embodiments, the laser emitting device 110 is arranged below the support portion 12, and the visible light generator 13 is arranged above the support portion 12. The orthographic projection of the laser emitting device 110 on the support portion 12 and the orthographic projection of the visible light generator 13 on the support portion 12 at least partially do not overlap. In this embodiment, the orthographic projection of the laser emitting device 110 on the support portion 12 and the orthographic projection of the visible light generator 13 on the support portion 12 do not overlap. In other embodiments, in this embodiment, the orthographic projection of the laser emitting device 110 on the support portion 12 and the orthographic projection of the visible light generator 13 on the support portion 12 may partially overlap. The support portion 12 is provided with a through hole 121 corresponding to the light emitting position of the visible light generator 13. The visible light beam emitted by the visible light generator 13 is emitted through the through hole 121 to mark a positioning spot on the surface of the workpiece to be processed.

[0056] Therefore, the visible light generator 13 is arranged above the support part 12, which can facilitate the operation of the fine-tuning mechanism 14. The support part 12 can support the visible light generator 13 and the fine-tuning mechanism 14 to prevent the visible light generator 13 from falling and being damaged due to accidents.

[0057] In some embodiments, the visible light generator 13 is a laser displacement sensor. It is understandable that in other embodiments, the visible light generator 13 is not limited to a laser displacement sensor, but may also be a point laser light source or other light sources that can propagate in the same direction, etc., which is not limited here. The laser generated by the visible light generator 13 may be, but is not limited to, red, and may also be green, blue, yellow and other visible light, which is not limited here. In addition, in some embodiments, when the visible light generator 13 is a laser displacement sensor, the laser displacement sensor can detect a first distance from the processing plane. When the workpiece to be processed is placed on the processing plane, the laser displacement sensor can detect a second distance from the surface of the workpiece to be processed. The difference between the first distance and the second distance can be used to obtain the material thickness of the workpiece to be processed, and further realize the laser focusing operation of the laser emitting device 110, thereby achieving precise focusing and laser processing.

[0058] In some embodiments, please refer to FIG. 3 and FIG. 4 , FIG. 3 is a schematic diagram of the three-dimensional structure of the visible light generator 13 and the fine-tuning mechanism 14 in an embodiment of the present application; FIG. 4 is a schematic diagram of the disassembly of FIG. 3 .

[0059] As shown in Figure 4, the visible light generator 13 includes a first side 131 and a third side 133 disposed opposite each other. In this embodiment, the first side 131 is the right side, and the third side 133 is the left side. It is understood that in other embodiments, the first side 131 is the left side, and the third side 133 is the right side. The visible light generator 13 also includes a second side 132 and a fourth side 134 disposed opposite each other. In this embodiment, the second side 132 is the rear side, and the fourth side 134 is the front side. It is understood that in other embodiments, the second side 132 is the front side, and the fourth side 134 is the rear side. The second side 132 connects the first side 131 and the third side 133 on the same side, and the fourth side 134 connects the first side 131 and the third side 133 on the other side. In some embodiments, the first side 131 and the third side 133 are parallel, and the second side 132 and the fourth side 134 are parallel. Therefore, the projection of the visible light generator 13 on the support portion 12 is a square. It is understood that in other embodiments, the first side 131 and the third side 133 may not be parallel. The second side 132 and the fourth side 134 may not be parallel. Therefore, the projection of the visible light generator 13 on the support portion 12 is a quadrilateral. In other embodiments, the visible light generator 13 is not limited to a square shape and may also be circular, elliptical, or other appropriate shapes, which are not limited here.

[0060] In some embodiments, referring again to Figures 3 and 4 , the fine-tuning mechanism 14 includes a first structural member 1411 and a second structural member 1421. The first structural member 1411 is connected to the visible light generator 13. The second structural member 1421 is connected to the laser emitting device 110. Specifically, in this embodiment, the second structural member 1421 is connected to the support portion 12 of the laser emitting device 110. The second structural member 1421 is rotatably connected to the first structural member 1411. The first structural member 1411 can rotate relative to the second structural member 1421 to adjust the light output direction of the visible light generator 13.

[0061] Thus, the rotational movement of the first structural member 1411 relative to the second structural member 1421 is used to adjust the light output direction of the visible light generator 13, so that the light output direction of the visible light beam emitted by the visible light generator 13 is parallel to the light output direction of the processing laser beam emitted by the laser output device 110.

[0062] In some embodiments, the first structural member 1411 is fixed to one side of the visible light generator 13 in a first direction. In this embodiment, the first direction is the X-axis. It is understood that in other embodiments, the first direction may also be the Y-axis. The second structural member 1421 is located on the side of the first structural member 1411 away from the visible light generator 13.

[0063] Therefore, the rotational movement of the first structural member 1411 relative to the second structural member 1421 is used to adjust the rotation angle of the visible light generator 13 in the first direction.

[0064] In some embodiments, a first shaft 1412 is rotatably connected between the first structural member 1411 and the second structural member 1421 .

[0065] In some specific embodiments, a first axis 1412 is provided on the first structural member 1411. A first hole 1422 is provided on the second structural member 1421. The first hole 1422 is sleeved on the first axis 1412. The rotational movement of the first structural member 1411 relative to the second structural member 1421 about the first axis 1412 is used to adjust the rotation angle of the visible light generator 13 in the first direction.

[0066] It is understood that in other embodiments, the first shaft 1412 can be provided on the second structural member 1421, and correspondingly, the first hole 1422 is provided on the first structural member 1411. In other embodiments, the second structural member 1421 and the first structural member 1411 can also be rotatably connected in other ways, which are not limited here.

[0067] In some embodiments, the fine-tuning mechanism 14 also includes a first adjusting portion 1414 and at least two first adjusting members 143. The first adjusting portion 1414 is connected to the first structural member 1411. At least two first adjusting members 143 are arranged at intervals. One end of the first adjusting member 143 is connected to the first adjusting portion 1414, and the other end is abutted against the second structural member 1421. The first adjusting member 143 can adjust the distance between the first adjusting portion 1414 and the second structural member 1421 to adjust the rotation angle of the first structural member 1411 relative to the second structural member 1421.

[0068] In some specific embodiments, the first adjustment portion 1414 extends from the first structural member 1411 toward the side close to the second structural member 1421, and the first adjustment portion 1414 is provided with at least two first adjustment holes 1415; at least two first adjustment members 143 are respectively passed through the at least two first adjustment holes 1415 and respectively abut against the second structural member 1421.

[0069] Thus, the first adjustment portion 1414 extends from the first structural member 1411 at any position on the side close to the second structural member 1421. Therefore, the distance between the first adjustment portion 1414 and the second structural member 1421 can be adjusted by at least two first adjustment members 143 arranged at intervals to adjust the rotation angle of the first structural member 1411 relative to the second structural member 1421 and thus adjust the light output direction of the colored light generator 13.

[0070] In some specific embodiments, the fine-tuning mechanism 14 includes a first fixing plate 141, which includes a first structural member 1411 and a first adjustment portion 1414. The first adjustment portion 1414 is fixed to the top of the first structural member 1411 and protrudes toward the side away from the visible light generator 13. In this embodiment, the first structural member 1411 is parallel to the first side surface 131, the first adjustment portion 1414 is perpendicular to the first structural member 1411, and the length of the first adjustment portion 1414 extends along the Y-axis, forming an L-shaped structure between the first adjustment portion 1414 and the first structural member 1411. It is understood that in other embodiments, the first adjustment portion 1414 may intersect with the first structural member 1411 but not be perpendicular. At least two first adjustment members 143 are respectively disposed through the at least two first adjustment holes 1415 and respectively abut against the first top surface 1423 of the second structural member 1421. Referring also to Figure 5 , when the position of the second structural member 1421 remains unchanged, the length by which the at least two first adjustment members 143 extend downward from the at least two first adjustment holes 1415 determines the inclination of the first adjustment portion 1414 relative to the first top surface 1423 of the second structural member 1421. Therefore, the rotation angle of the visible light generator 13 in the first direction is determined by the length by which the at least two first adjustment members 143 extend downward from the at least two first adjustment holes 1415. Because the first top surface 1423 of the second structural member 1421 lacks threaded holes corresponding to the first adjustment members 143, increasing the length by which the first adjustment members 143 extend downward from the first adjustment holes 1415 raises the position of the first adjustment portion 1414 adjacent to the first adjustment member 143. Conversely, decreasing the length by which the first adjustment member 143 extends downward from the first adjustment hole 1415 lowers the position of the first adjustment portion 1414 adjacent to the first adjustment member 143.

[0071] Therefore, the rotation angle of the first fixing plate 141 relative to the second structural member 1421 in the first direction can be adjusted by respectively extending the at least two first adjusting members 143 downward by the lengths of the at least two first adjusting holes 1415 .

[0072] In other embodiments, the first adjustment portion 1414 is connected to the second structural member 1421, and at least two first adjustment members 143 are arranged at intervals. One end of the first adjustment member 143 is connected to the first adjustment portion 1414, and the other end abuts against the first structural member 1411. The first adjustment member 143 can adjust the distance between the first adjustment portion 1414 and the first structural member 1411 to adjust the rotation angle of the first structural member 1411 relative to the second structural member 1421.

[0073] In other specific embodiments, the first adjustment portion 1414 extends from the second structural member 1421 toward the side close to the first structural member 1411, and the first adjustment portion 1414 is provided with at least two first adjustment holes 1415; at least two first adjustment members 143 are respectively passed through the at least two first adjustment holes 1415 and respectively supported against the first structural member 1411.

[0074] Thus, the first adjustment portion 1414 extends from the second structural member 1421 toward any position on the side close to the first structural member 1411. Therefore, the distance between the first adjustment portion 1414 and the first structural member 1411 can be adjusted by at least two first adjustment members 143 arranged at intervals to adjust the rotation angle of the first structural member 1411 relative to the second structural member 1421, thereby adjusting the light output direction of the colored light generator 13.

[0075] In some embodiments, referring to FIG5 , the fine-tuning mechanism 14 further includes a long bolt 140. The long bolt 140 extends through the visible light generator 13 along a first direction and is connected to the first structural member 1411 of the first fixing plate 141. It is understood that in other embodiments, the visible light generator 13 may be connected to the first structural member 1411 of the first fixing plate 141 in other ways, which are not limited herein.

[0076] In some embodiments, referring again to FIG4 , the fine-tuning mechanism 14 further includes a first stopper 148. The first stopper 148 is connected between the first structural member 1411 and the second structural member 1421 to prevent the first structural member 1411 and the second structural member 1421 from separating.

[0077] In some specific embodiments, the first shaft 1412 is passed through the first hole 1422, and a first connecting hole 1413 is provided on the free end of the first shaft 1412 passing through the first hole 1422; one end of the first limiting member 148 is threadedly connected to the first connecting hole 1413, and the outer diameter of the other end of the first limiting member 148 is larger than the inner diameter of the first hole 1422.

[0078] Thus, one end of the first limiting member 148 is threadedly connected to the first connecting hole 1413, and the outer diameter of the head of the first limiting member 148 is larger than the inner diameter of the first hole 1422, thereby limiting the relative movement of the first structural member 1411 and the second structural member 1421, so that the first structural member 1411 will not separate from the second structural member 1421.

[0079] In some embodiments, referring again to FIG. 4 , the fine-tuning mechanism 14 further includes a first locking member 146. A first locking hole 1417 is defined in the first structural member 1411. A first movable hole 1427 is also defined in the second structural member 1421. One end of the first locking member 146 abuts against the second structural member 1421, while the other end passes through the first movable hole 1427 and connects to the first locking hole 1417. When the first locking member 146 is released from the first structural member 1411 or the second structural member 1421, the first locking member 146 can move within the first movable hole 1427.

[0080] Therefore, when the rotation angle of the first structural member 1411 relative to the second structural member 1421 in the first direction is determined, the first locking member 146 is passed through the first movable hole 1427 and is threadedly connected to the first locking hole 1417 for locking.

[0081] In some embodiments, the first movable hole 1427 is an arc-shaped hole with the center of the first hole 1422 (the first axis 1412 ) as the center and the distance between the first hole 1422 and the first movable hole 1427 as the radius.

[0082] In some embodiments, the number of the first locking member 146, the first movable hole 1427, and the first locking hole 1417 is 2, respectively. In other embodiments, the number of the first locking member 146, the first movable hole 1427, and the first locking hole 1417 is 1, respectively. In still other embodiments, there is one first movable hole 1427, and the number of the first locking member 146 and the number of the first locking hole 1417 are both plural. The multiple first locking members 146 are respectively located at different positions on the same first movable hole 1427. In still other embodiments, the number of the first locking member 146, the first movable hole 1427, and the first locking hole 1417 are both plural, and the radii of different first movable holes 1427 can be the same or different. The number of the first locking member 146 and the first locking hole 1417 corresponding to each first movable hole 1427 can be one or more, which is not limited here.

[0083] In some embodiments, the fine-tuning mechanism 14 further includes a third structural member 1424 and a fourth structural member 1441 rotatably connected to the third structural member 1424. The third structural member 1424 is connected to the second structural member 1421 and is located on one side of the visible light generator 13 in the second direction. The fourth structural member 1441 is connected to the support portion 12. The second direction intersects or is perpendicular to the first direction. In this embodiment, the second direction is the Y-axis direction. In other embodiments, the second direction may be the X-axis direction.

[0084] In other embodiments, the third structural member 1424 may be directly connected to the visible light generator 13 .

[0085] Therefore, the rotational movement of the third structural member 1424 relative to the fourth structural member 1441 is used to adjust the rotation angle of the visible light generator 13 in the second direction.

[0086] In some specific embodiments, the third structural member 1424 is disposed corresponding to the second side surface 132 of the visible light generator 13. The fourth structural member 1441 is disposed corresponding to the second side surface 132 of the visible light generator 13. The bottom end of the fourth structural member 1441 is fixed to the support portion 12.

[0087] In this embodiment, third structural member 1424 is located between second side surface 132 of visible light generator 13 and fourth structural member 1441, and is disposed parallel to each other. In other embodiments, third structural member 1424 may be located on a side of fourth structural member 1441 away from second side surface 132 of visible light generator 13, and may be disposed parallel to each other, without limitation herein.

[0088] In some embodiments, a second shaft 1442 is rotatably connected between the third structural member 1424 and the fourth structural member 1441 .

[0089] Referring to Figure 4 , in some specific embodiments, the fourth structural member 1441 is provided with a second shaft 1442. The second shaft 1442 is arranged along the second direction. Also referring to Figure 7 , the third structural member 1424 is provided with a second hole 1425. The central axes of the second shaft 1442 and the second hole 1425 are both parallel to the second direction. The second hole 1425 is sleeved onto the second shaft 1442. In other embodiments, the second hole 1425 may be provided on the fourth structural member 1441, and the second shaft 1442 may be provided on the third structural member 1424.

[0090] Therefore, when the third structural member 1424 rotates around the second axis 1442 relative to the fourth structural member 1441, it can drive the visible light generator 13 to rotate relative to the second axis 1442, and the rotation angle of the visible light generator 13 in the second direction can be adjusted, thereby adjusting the light output direction of the visible light generator 13.

[0091] In some embodiments, the first axis 1412 is perpendicular to the second axis 1442 .

[0092] In some embodiments, the fine-tuning mechanism 14 includes an adapter plate 142, which includes a third structural member 1424 and a second structural member 1421. The third structural member 1424 is connected to the second structural member 1421. The third structural member 1424 and the second structural member 1421 intersect to form an L shape.

[0093] Thus, the motion linkage between the third structural member 1424 and the second structural member 1421 can be increased, thereby improving the adjustment accuracy.

[0094] In some embodiments, please refer to Figures 4, 6 and 7, the fine-tuning mechanism 14 also includes a second adjusting portion 1443 and at least two second adjusting members 145, the second adjusting portion 1443 is connected to the fourth structural member 1441, and at least two adjusting members 145 are arranged at intervals, one end of the second adjusting member 145 is connected to the second adjusting portion 1443, and the other end is abutted against the third structural member 1424, and the second adjusting member 145 adjusts the distance between the second adjusting portion 1443 and the third structural member 1424 to adjust the rotation angle of the third structural member 1424 relative to the fourth structural member 1441 around the second direction.

[0095] In some specific embodiments, the second adjustment portion 1443 extends from the fourth structural member 1441 toward the side close to the third structural member 1424, and the second adjustment portion 1443 is provided with at least two second adjustment holes 1444; at least two second adjustment members 145 are respectively passed through the at least two second adjustment holes 1444 and respectively supported against the third structural member 1424.

[0096] Thus, the second adjustment portion 1443 extends from the fourth structural member 1441 toward any position on the side close to the third structural member 1424. Therefore, the distance between the second adjustment portion 1443 and the third structural member 1424 can be adjusted by at least two spaced-apart second adjustment members 145 to adjust the rotation angle of the third structural member 1424 relative to the fourth structural member 1441, thereby adjusting the light emission direction of the colored light generator 13.

[0097] In some specific embodiments, the second adjustment portion 1443 is fixed to the top of the fourth structural member 1441 and protrudes toward the side close to the third structural member 1424. An inverted L-shaped structure is formed between the second adjustment portion 1443 and the fourth structural member 1441. In this embodiment, the fourth structural member 1441 is parallel to the second side surface 132. The second adjustment portion 1443 is perpendicular to the fourth structural member 1441, and the length direction of the second adjustment portion 1443 extends along the X-axis direction. Please refer to Figures 8 and 9. At least two second adjustment members 145 are respectively inserted into the at least two second adjustment holes 1444 and respectively abut against the second top surface 14250 of the third structural member 1424. When the position of the adapter plate 142 does not change, the length of the at least two second adjustment members 145 extending downward from the at least two second adjustment holes 1444 determines the inclination of the second adjustment portion 1443 relative to the second top surface 14250 of the third structural member 1424. Therefore, the rotation angle of the visible light generator 13 in the second direction is determined by the length of the at least two second adjustment members 145 extending downward from the at least two second adjustment holes 1444. Because the second top surface 14250 of the third structural member 1424 lacks threaded holes corresponding to the second adjustment members 145, as the length of the second adjustment member 145 extending downward from the second adjustment hole 1444 increases, the position of the second adjustment portion 1443 adjacent to the second adjustment member 145 is raised. Conversely, as the length of the second adjustment member 145 extending downward from the second adjustment hole 1444 decreases, the position of the second adjustment portion 1443 adjacent to the second adjustment member 145 is lowered.

[0098] Therefore, the rotation angle of the third structure member 1424 relative to the fourth structure member 1441 in the second direction can be adjusted by respectively extending the length of the at least two second adjustment members 145 downwardly through the at least two second adjustment holes 1444 .

[0099] In other embodiments, the second adjustment portion 1443 is connected to the third structural member 1424, and at least two second adjustment members 145 are arranged at intervals. One end of the second adjustment member 145 is connected to the second adjustment portion 1443, and the other end is abutted against the fourth structural member 1441. At least two second adjustment members 145 adjust the distance between the second adjustment portion 1443 and the fourth structural member 1441 to adjust the rotation angle of the third structural member 1424 relative to the fourth structural member 1441 around the second direction.

[0100] In other specific embodiments, the second adjustment portion 1443 extends from the third structural member 1424 toward the side close to the fourth structural member 1441, and the second adjustment portion 1443 is provided with at least two second adjustment holes 1444; at least two second adjustment members 145 are respectively passed through the at least two second adjustment holes 1444 and respectively supported against the fourth structural member 1441.

[0101] Thus, the second adjustment portion 1443 extends from the third structural member 1424 at any position on the side close to the fourth structural member 1441. Therefore, the distance between the second adjustment portion 1443 and the fourth structural member 1441 can be adjusted by at least two spaced-apart second adjustment members 145 to adjust the rotation angle of the third structural member 1424 relative to the fourth structural member 1441 and thereby adjust the light emission direction of the colored light generator 13.

[0102] In some embodiments, the fine-tuning mechanism 14 further includes a second fixing plate 144 , and the second fixing plate 144 includes a fourth structural member 1441 and a second adjusting portion 1443 .

[0103] In some embodiments, the fine-tuning mechanism 14 further includes a second limiting member 147 , which is connected between the third structural member 1424 and the fourth structural member 1441 to limit the third structural member 1424 and the fourth structural member 1441 from being separated.

[0104] In some specific embodiments, a second shaft 1442 is provided on one of the third structural member 1424 and the fourth structural member 1441, and a second hole 1425 is provided on the other one. The second shaft 1442 is passed through the second hole 1425, and a second connecting hole is correspondingly provided on the end of the second shaft 1442 that passes through the second hole 1425; one end of the second limiting member 147 is threadedly connected to the second connecting hole, and the outer diameter of the other end of the second limiting member 147 is larger than the inner diameter of the second hole 1425.

[0105] Thus, when the third structural member 1424 rotates to a desired angle relative to the fourth structural member 1441 around the second axis 1442, the second limiting member 147 is inserted into the second hole 1425 from the side of the second hole 1425 away from the fourth structural member 1441, and is threadedly connected to the second connecting hole of the second axis 1442. Moreover, the head of the second limiting member 147 abuts against the surface of the third structural member 1424 away from the fourth structural member 1441, thereby achieving preliminary locking of the relative positions of the third structural member 1424 and the fourth structural member 1441. It can be understood that when the second hole 1425 is arranged on the fourth structural member 1441 and the second shaft 1442 is arranged on the third structural member 1424, the second limiting member 147 is inserted into the second hole 1425 from the side of the second hole 1425 away from the third structural member 1424, and is threadedly connected to the second connecting hole of the second shaft 1442. Moreover, the head of the second limiting member 147 abuts against the surface of the fourth structural member 1441 away from the third structural member 1424, thereby achieving preliminary locking of the relative positions of the third structural member 1424 and the fourth structural member 1441.

[0106] In some embodiments, referring again to FIG. 4 , the fine-tuning mechanism 14 further includes a second locking member 149 . A second locking hole 1449 is provided on the third structural member 1424 . A second movable hole 1448 is also provided on the fourth structural member 1441 . One end of the second locking member 149 abuts against the fourth structural member 1441 , while the other end passes through the second movable hole 1448 and connects to the second locking hole 1449 . When the second locking member 149 is released from the third structural member 1424 or the fourth structural member 1441 , the second locking member 149 can move within the second movable hole 1448 .

[0107] In some embodiments, the second movable hole 1448 is an arc-shaped hole with the center of the second shaft 1442 as the center and the distance between the second shaft 1442 and the second movable hole 1448 as the radius.

[0108] Therefore, when the rotation angle of the second fixing plate 144 relative to the adapter plate 142 in the Y-axis direction is determined, the second locking member 149 is passed through a predetermined position of the second movable hole 1448 and threadedly connected in the second locking hole 1449 for locking.

[0109] In some embodiments, the number of the second locking member 149, the number of the second movable hole 1448, and the number of the second locking hole 1449 are each two. In other embodiments, the number of the second locking member 149, the number of the second movable hole 1448, and the number of the second locking hole 1449 are each one. In other embodiments, there is one second movable hole 1448, and there are multiple second locking members 149 and multiple second locking holes 1449; the multiple second locking members 149 are respectively located at different positions on the same second movable hole 1448. In still other embodiments, there are multiple second locking members 149, the number of the second movable hole 1448, and the number of the second locking members 149 and the second locking holes 1449 are respectively multiple, and the radii of different second movable holes 1448 can be the same or different. Each second movable hole 1448 can correspond to one or more second locking members 149 and second locking holes 1449, which are not limited here.

[0110] In some embodiments, as shown in FIG7 , the second fixing plate 144 further includes a bottom plate 1447. The bottom plate 1447, the fourth structural member 1441, and the second adjustment portion 1443 form a U-shaped structure. Referring to FIG2 , a slot 122 is provided on the sidewall of the support portion 12. The bottom plate 1447 is inserted into the slot 122. The adapter plate 142 is rotatably connected to the second fixing plate 144.

[0111] Therefore, the second fixing plate 144 can be stably fixed on the supporting portion 12 .
