Description

Technical Field

[0001] The present invention relates to the technical field of laser cleaning, and in particular to a laser cleaning optical path conversion device and method. Background Art

[0002] In conventional cleaning head optical path designs, the angles of incident and emitted light are fixed, and one of these angles is selected based on the application scenario. Due to the increasing application areas of laser cleaning, a single light output angle cannot meet the needs of various applications. For example, vertical light output is more convenient when cleaning floors, but when cleaning walls, especially at the junction of walls and floors, the vertical light output cleaning head structure will cause the optical fiber to bend, requiring parallel light output. The traditional solution is to use multiple sets of cleaning equipment, replacing them for different application scenarios, resulting in wasted equipment utilization, slow switching time, and reduced production efficiency.

[0003] The present application proposes a laser cleaning optical path conversion device, which can adjust the optical path structure to quickly convert the light output angle on the same set of cleaning heads, thereby improving production efficiency and avoiding equipment waste.

[0004] Utility model patent publication number CN 204178096 U discloses a reflective lens optical path conversion mechanism. The mechanism comprises a reflective lens holder, an infrared reflective lens, and a visible light reflective lens. The infrared and visible light reflective lenses are fixed to the reflective lens holder, with the principal optical axes of the infrared and visible light reflective lenses perpendicular to each other. A rotary handle is provided on the reflective lens holder, which rotates the holder 90 degrees back and forth to select either the infrared or visible light reflective lens to enter the optical path. The reflective lens holder is positioned by a positioning spring connected to a positioning plate. This utility model features a simple and compact structure, easy adjustment and conversion, and precise and reliable positioning.

[0005] Although the above technical solution has a similar structure to the present application, the purposes achieved by the two are different. The above prior art actually switches the lenses, while the present application achieves the conversion of the light path direction by adjusting the angle of the laser light path. Summary of the Invention

[0006] The present invention provides a laser cleaning optical path conversion device and method, which solves the problems mentioned in the above background technology.

[0007] The technical solution of the present invention is achieved as follows:

[0008] A laser cleaning optical path conversion device includes an L-shaped bracket, an optical path output tube arranged on the back of the L-shaped bracket, guide plates arranged on both sides of the L-shaped bracket, an optical path reflector located on the inner side of the L-shaped bracket and capable of flipping and moving on the guide plates, and a laser head capable of flipping and moving on the guide plates in response to the top of the optical path reflector;

[0009] A reflector moving part that flips in an arc shape along the inner side of the guide plate is provided on the outside of the optical path reflector, and a laser head moving part that flips in an arc shape along the inner side of the guide plate is provided on the outside of the laser head. The laser head moving part is connected to the reflector moving part by installing an elastic part so that it flips synchronously after being pulled.

[0010] Furthermore, the moving part of the reflector includes a hollow plate located at the bottom of the fixed cylinder and inside the L-shaped bracket, and a first connecting block installed on the front side of the bottom of the hollow plate; the moving part of the laser head includes a fixed cylinder mounted on the outside of the input end of the laser head, and a second connecting block installed on the front side of the fixed cylinder; the two ends of the elastic member are respectively hung on the first connecting block and the second connecting block.

[0011] Furthermore, a guide arm is fixed on each side of the fixed cylinder, and the first fixed bearing and the first movable bearing located in the guide plate are fixed at both ends of the outer side of the guide arm respectively. The guide plate is provided with a first adapter groove adapted to the first fixed bearing, and a laser head guide groove adapted to flip and slide with the second movable bearing.

[0012] Furthermore, the laser head guide groove is an arc-shaped groove, the laser head guide groove takes the first adapting groove as the center, and its flip angle is 90°.

[0013] Furthermore, the two sides of the hollow plate are respectively adapted to the second fixed bearing and the second movable bearing in the guide plate. The guide plate is provided with a second adaption groove adapted to the second fixed bearing and a reflector guide groove adapted to the flipping and sliding of the second movable bearing.

[0014] Furthermore, the reflector guide groove is an arc groove, with the second adapting groove as the center, and its flip angle is 45°

[0015] Furthermore, the optical path reflector before flipping is located at the vertical angle between the optical path output tube and the laser head; and the optical path reflector after flipping is located at the bottom of the overlapping parallel lines of the optical path output tube and the laser head.

[0016] A laser cleaning optical path conversion method is provided, which uses the laser cleaning pipeline conversion device. The specific operation steps are as follows:

[0017] Before the optical path direction conversion operation, the laser head, the laser head moving part, the optical path reflector and the reflector moving part are all arranged horizontally, and the optical path output of the optical path output tube is horizontally irradiated on the laser head, realizing the horizontal optical path output of the laser head;

[0018] The input end of the laser head corresponds to the output end of the optical output tube, and the exterior of the laser head is supported by the laser head moving part. Specifically, the first connecting block on the laser head moving part contacts the inner surface of the L-shaped bracket. The balance of the laser head moving part is achieved by the first fixed bearing and the first movable bearing on both sides being respectively adapted to the first adapting groove of the guide plate and the laser head guide groove.

[0019] In addition, the optical path reflector is located at the bottom of the laser head moving part, and the exterior of the optical path reflector is supported by the reflector moving part. Specifically, the second connecting block on the reflector moving part contacts the inner plane of the L-shaped bracket, and the second fixed bearing and the second movable bearing on both sides of the reflector moving part are respectively adapted to the second adapting groove of the guide plate and the reflector guide groove to achieve;

[0020] S1: The user applies force to flip the laser head with his hand, and the flipping direction changes from horizontal to vertical. Since the fixed cylinder on the moving part of the laser head is sleeved on the outside of the input end of the laser head, the force of the laser head acts on the fixed cylinder, and the guide arms on both sides of the fixed cylinder are respectively provided with a first fixed bearing and a first movable bearing. The first fixed bearing serves as the center of the flipping circle of the laser head moving part and rotates in the first adapter groove of the guide plate, while the first movable bearing revolves around the center of the circle along the laser head guide groove of the guide plate. Therefore, the flipping movement of the laser head moving part takes the first fixed bearing as the center of the circle, and uses the first movable bearing to slide in an arc along the laser head guide groove;

[0021] S2: In the laser head moving part, an elastic member is hung on the second connecting block on the fixed cylinder, and the elastic member is hung away from the second connecting block and the first connecting block on the reflector moving part. When the laser head moving part flips, the elastic member moves synchronously, and then the elastic member drives the reflector moving part to rotate together;

[0022] S3: A second fixed bearing and a second movable bearing are provided on both sides of the reflector moving part. The second fixed bearing serves as the center of the circle for the reflector moving part to flip and rotates in the second adapter groove of the guide plate, while the second movable bearing revolves around the center of the circle along the reflector guide groove of the guide plate. The flipping movement of the reflector moving part takes the second fixed bearing as the center of the circle, and the second movable bearing slides in an arc along the reflector guide groove until it slides from the starting end to the end of the reflector guide groove.

[0023] S4: When the reflector moving part rotates 45°, the reflector guide groove will restrict its further rotation, but the laser head moving part can continue to rotate to 90° by virtue of the 90° setting of the laser head guide groove, until it flips from horizontal to vertical. At this time, the elastic member cooperates with the reflector moving part to stretch the elastic member, so that the laser head moving part is restricted to the 90° position and then fixed;

[0024] S5: The reflector moving part is in the 45° state, and the light output of the light output tube is irradiated on the light path reflector in the reflector moving part. The light path reflector refracts the light path toward the laser head, and then the horizontal light path is converted into a vertical light path.

[0025] The beneficial effects of the technical solution provided by this application are:

[0026] This laser cleaning optical path conversion device and method uses an optical path converter to convert the original horizontal light output path to a vertical one, addressing the light output requirements of different application scenarios. It enables rapid conversion of light output angles on the same cleaning head, improving production efficiency and avoiding equipment waste. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Reference Figure 1-5 A laser cleaning optical path conversion device includes an L-shaped bracket 10, an optical path output tube 20 provided on the back of the L-shaped bracket, guide plates 30 provided on both sides of the L-shaped bracket 10, an optical path reflector 40 located inside the L-shaped bracket 10 and capable of flipping on the guide plates 30, and a laser head 50 capable of flipping on the guide plates 30 corresponding to the top of the optical path reflector 40;

[0036] The above technical solution achieves rapid conversion of light output angles through the optical path conversion device, thereby improving production efficiency and avoiding equipment waste. The L-shaped bracket 10 provides structural support and fixation, ensuring the stability of the entire optical path conversion device. The optical path output tube 20, located on the back of the L-shaped bracket 10, guides the output of the laser cleaning optical path. Guide plates 30, located on either side of the L-shaped bracket 10, guide the flipping motion of the optical path reflector 40 and the laser head 50 and ensure the accuracy of their motion trajectory. The optical path reflector 40 is located inside the guide plate 30 and flips on the guide plate 30. It selects the direction of light reflection by flipping. The laser head 50 corresponds to the optical path reflector 40, is connected to the optical path reflector 40 at its top, and flips on the guide plate 30. The position of the laser head 50 is consistent with that of the optical path reflector 40 to ensure the continuity of the optical path. Using the same cleaning device for laser cleaning in multiple application scenarios avoids low equipment utilization and resource waste.

[0037] The optical path reflector 40 is provided with a reflector moving part 60 on the outside that flips in an arc along the inner side of the guide plate 30. The laser head 50 is provided with a laser head moving part 70 on the outside that flips in an arc along the inner side of the guide plate 30. The laser head moving part 70 is connected to the reflector moving part 60 by installing an elastic part 80 so that it flips synchronously after being pulled.

[0038] The above technical solution disposes a reflector moving part 60 and a laser head moving part 70 outside the optical path reflector 40 and the laser head 50, and connects them by installing an elastic member 80 to enable synchronous flipping. This design can solve the problem of synchronous movement of the optical path reflector 40 and the laser head 50 during the laser cleaning optical path conversion process. The reflector moving part 60 and the laser head moving part 70 respectively perform arc-shaped flipping motion along the inner side of the guide plate 30. To achieve this synchronous flipping, the laser head moving part 70 is connected to the reflector moving part 60 by installing an elastic member 80. When the operator controls the laser head moving part 70 to flip, the elastic member 80 pulls the reflector moving part 60, causing it to flip synchronously. Through this design, the angles of the laser head 50 and the optical path reflector 40 can be changed synchronously, ensuring the accuracy and stability of the light output angle. Due to the action of the elastic member 80, the reflector moving part 60 and the laser head moving part 70 can be pulled and flipped synchronously, ensuring that the angle changes between the two remain consistent. In this way, when performing optical path conversion, the change of the laser light output angle can be accurately controlled, thereby improving the cleaning effect and working stability.

[0039] In a further embodiment, the reflector moving portion 60 includes a hollow plate 61 located at the bottom of a fixed cylinder 71 and inside the L-shaped bracket 10, and a first connecting block 62 mounted on the front side of the bottom of the hollow plate 61. The laser head moving portion 70 includes a fixed cylinder 71 mounted outside the input end of the laser head 50, and a second connecting block 72 mounted on the front side of the fixed cylinder 71. The ends of the elastic member 80 are respectively suspended on the first connecting block 62 and the second connecting block 72. The above technical solution specifically discloses the components of the elastic member 80 that are connected to the two moving portions, namely the first connecting block 62 and the second connecting block 72. Its main purpose is to provide a certain connection between the elastic member 80 and the two moving portions, thereby facilitating the movement of the laser head moving portion 70 and utilizing the elastic member 80 to pull the reflector moving portion 60 for synchronous movement.

[0040] The elastic member 80 in the above solution can specifically be a spring, an elastic belt or an elastic rope, which is deformed and stretched under the movement of the laser head moving part 70, and the two moving parts are limited by the tension.

[0041] In some embodiments, the fixed cylinder 71 is secured to either side with a guide arm 73. A first fixed bearing 74 and a first movable bearing 75, located in the guide plate 30, are secured to the outer ends of the guide arms 73. The guide plate 30 defines a first adapting slot 31 for the first fixed bearing 74 and a laser head guide slot 32 for the second movable bearing 75 to rotate and slide. The guide arms 73 on the outer sides of the fixed cylinder 71 provide a connection between the first fixed bearing 74 and the first movable bearing 75. The first fixed bearing 74 fits into the first adapting slot 31 of the guide plate 30, providing axial positioning and support for the fixed cylinder 71. The first movable bearing 75 is movable relative to the first fixed bearing 74, allowing a certain degree of free sliding and tilting movement within the fixed cylinder 71. This structural arrangement enables the fixed cylinder 71 to slide axially and rotate with the support of the guide arms 73. The first fixed bearing 74 provides initial support and positioning, while the first movable bearing 75 and the laser head guide slot 32 enable the laser head to rotate and slide in specific directions to achieve various angles.

[0042] In one embodiment, the laser head guide groove 32 is an arc-shaped groove, and the laser head guide groove 32 takes the first adapter groove 31 as the center, and its flip angle is 90°. Since the laser head guide groove 32 is an arc-shaped groove, its shape and arc length determine the motion range of the laser head. When the laser head slides along the groove, it can flip within this 90° range. Such a design can ensure that the laser head can cover a wider area during the cleaning process and achieve a more comprehensive cleaning effect. Through the arc-shaped design of the laser head guide groove 32 and the cooperation with the first adapter groove 31, the laser head can be stably flipped and slid within a range of 90°. Such a structural design has high precision and stability, effectively improving the efficiency and accuracy of the cleaning process.

[0043] In a further embodiment, the hollow plate 61 is adapted on either side to fit a second fixed bearing 63 and a second movable bearing 64 in the guide plate 30, respectively. The guide plate 30 is provided with a second adapting groove 33 adapted to fit the second fixed bearing 63, as well as a reflector guide groove 34 that cooperates with the second movable bearing 64 for tilting and sliding. The second fixed bearing 63, by fitting into the second adapting groove 33, provides a fixed position and axial support for the reflector moving portion 60. The second movable bearing 64, also located in the guide plate 30, is movable relative to the second fixed bearing 63, allowing a certain degree of free sliding and tilting movement on one side of the hollow plate 61. The second adapting groove 33 is a groove in the guide plate 30 specifically designed to fit the second fixed bearing 63 and provide positioning and support. The reflector guide groove 34 is a groove that cooperates with the second movable bearing 64 and guides the reflector. The design of the reflector guide groove 34 enables the reflector to tilt and slide during the cleaning process. With the above structural arrangement, one side of the hollow plate 61 can slide axially and tilt with the support of the guide plate 30. The second fixed bearing 63 provides initial support and positioning, while the second movable bearing 64 and the reflector guide groove 34 enable the reflector to flip and slide in a specific direction.

[0044] In some embodiments, the reflector guide groove 34 is an arc-shaped groove, and the reflector guide groove 34 takes the second adapter groove 33 as the center, and its flip angle is 45°. Since the reflector guide groove 34 is an arc-shaped groove, its shape and arc length determine the motion range of the reflector. When the reflector slides along the groove, it can flip within this 45° range. Such a design can ensure that the reflector can cover a wider angle range during the cleaning process and achieve a more comprehensive cleaning effect. Through the arc-shaped design of the reflector guide groove 34 and the cooperation with the second adapter groove 33, the reflector can be stably flipped and slid within a 45° range. Such a structural design has high precision and stability, effectively improving the efficiency and accuracy of the cleaning process.

[0045] In one embodiment, the light path reflector 40 before flipping is located at the vertical angle between the light path output tube 20 and the laser head 50; after flipping, the light path reflector 40 is located at the bottom of the overlapping parallel lines of the light path output tube 20 and the laser head 50. In the above technical solution, the light path reflector 40 before flipping is located at the vertical angle between the light path output tube 20 and the laser head 50. This means that the light path reflector 40 is used to change the propagation direction of light so that the light is transmitted from the light path output tube 20 to the laser head 50 and forms a vertical angle with the two. After flipping, the light path reflector 40 is located at the bottom of the overlapping parallel lines of the light path output tube 20 and the laser head 50. This shows that the position after flipping has changed relative to that before flipping, and it is aligned with the bottom of the overlapping parallel lines formed by the light path output tube 20 and the laser head 50.

[0046] This configuration allows the optical path reflector 40 to flip and transmit light from the optical output tube 20 to the laser head 50. Before flipping, the optical path reflector 40 is located at a perpendicular angle between the optical output tube 20 and the laser head 50, ensuring that light properly enters the laser head 50. After flipping, the optical path reflector 40 is located at the bottom of the overlapping parallel lines, and the light path from the optical output tube 20 is projected directly into the laser head 50, maintaining the continuity and accuracy of light transmission. This optical path configuration helps ensure the correct steering and transmission of light within the system, allowing optical devices to operate as expected and provide the required functionality and performance.

[0047] A laser cleaning optical path conversion method is provided, which uses the laser cleaning pipeline conversion device. The specific operation steps are as follows:

[0048] Before the optical path direction conversion operation, the laser head 50, the laser head moving part 70, the optical path reflector 40 and the reflector moving part 60 are all arranged horizontally, and the optical path output of the optical path output tube 20 is horizontally irradiated on the laser head 50, realizing the horizontal optical path output of the laser head 50;

[0049] The input end of the laser head 50 corresponds to the output end of the optical output tube 20. The laser head 50 is externally supported by a laser head moving portion 70. Specifically, the first connecting block 62 on the laser head moving portion 70 contacts the inner surface of the L-shaped bracket 10. The balance of the laser head moving portion 70 is achieved by the first fixed bearing 74 and the first movable bearing 75 on both sides being respectively adapted to the first adapting groove 31 and the laser head guide groove 32 of the guide plate 30.

[0050] In addition, the optical path reflector 40 is located at the bottom of the laser head moving part 70, and the exterior of the optical path reflector 40 is supported by the reflector moving part 60. Specifically, the second connecting block 72 on the reflector moving part 60 contacts the inner surface of the L-shaped bracket 10, and the second fixed bearing 63 and the second movable bearing 64 on both sides of the reflector moving part 60 are respectively adapted to the second adapting groove 33 and the reflector guide groove 34 of the guide plate 30 to achieve;

[0051] S1: The user applies force to flip the laser head 50 with his hand, and the flipping direction changes from horizontal to vertical. Since the fixed cylinder 71 on the laser head moving part 70 is sleeved on the outside of the input end of the laser head 50, the force of the laser head 50 acts on the fixed cylinder 71, and the guide arms 73 on both sides of the fixed cylinder 71 are respectively provided with a first fixed bearing 74 and a first movable bearing 75. The first fixed bearing 74 serves as the center of the flipping circle of the laser head moving part 70 and rotates in the first adapter groove 31 of the guide plate 30, while the first movable bearing 75 revolves around the center of the circle along the laser head guide groove 32 of the guide plate 30. Therefore, the flipping movement of the laser head moving part 70 takes the first fixed bearing 74 as the center of the circle, and utilizes the first movable bearing 75 to slide in an arc along the laser head guide groove 32;

[0052] S2: In the laser head moving part 70, an elastic member 80 is hung on the second connecting block 72 on the fixed cylinder 71, and the elastic member 80 is hung away from the second connecting block 72 and the first connecting block 62 on the reflector moving part 60. When the laser head moving part 70 is flipped, the elastic member 80 moves synchronously, and then the elastic member 80 drives the reflector moving part 60 to rotate together;

[0053] S3: A second fixed bearing 63 and a second movable bearing 64 are provided on both sides of the reflector moving portion 60. The second fixed bearing 63 serves as the center of the circle for the reflector moving portion 60 to rotate in the second adapting groove 33 of the guide plate 30, while the second movable bearing 64 revolves around the center of the circle along the reflector guide groove 34 of the guide plate 30. The reflector moving portion 60 rotates with the second fixed bearing 63 as the center of the circle, and slides in an arc along the reflector guide groove 34 using the second movable bearing 64 until it slides from the starting end to the end of the reflector guide groove 34.

[0054] S4: When the reflector moving part 60 rotates 45°, the reflector guide groove 34 will restrict its further rotation. However, the laser head moving part 70 can continue to rotate to 90° by virtue of the 90° setting of the laser head guide groove 32, until it flips from the horizontal to the vertical. At this time, the elastic member 80 cooperates with the reflector moving part 60 to stretch the elastic member 80, so that the laser head moving part 70 is restricted to the 90° position and then fixed.

[0055] S5: The reflector moving part 60 is in a 45° state, and the light output of the light output tube 20 is irradiated on the light path reflector 40 in the reflector moving part 60. The light path reflector 40 refracts the light path toward the laser head 50, thereby converting the horizontal light output path into a vertical light output path.

[0056] Through this method, the horizontal optical path output of the laser head can be converted into a vertical optical path output, achieving a change in the direction of the optical path. This method uses a simple mechanical structure such as a fixed cylinder, a guide arm, and a connecting block to enable the laser head moving part and the reflector moving part to flip while ensuring the reliability and stability of the structure. Through the design of fixed bearings and movable bearings, precise motion control of the laser head moving part and the reflector moving part can be achieved, as well as arc-shaped sliding along the guide plate, thereby ensuring precise focusing and adjustment of the optical path. During the flipping process, the optical path reflector is used to refract the horizontally irradiated light path toward the laser head, achieving the conversion of the horizontal light output path to the vertical light output path, ensuring accurate and efficient cleaning results.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

Specifically, the first connecting block (62) on the laser head moving part (70) contacts the inner surface of the L-shaped bracket (10), and the balance of the laser head moving part (70) is achieved by the first fixed bearing (74) and the first movable bearing (75) on both sides being respectively adapted to the first adapting groove (31) of the guide plate (30) and the laser head guide groove (32); In addition, the optical path reflector (40) is located at the bottom of the laser head moving part (70), and the outside of the optical path reflector (40) is supported by the reflector moving part (60). Specifically, the second connecting block (72) on the reflector moving part (60) contacts the inner plane of the L-shaped bracket (10), and the second fixed bearing (63) and the second movable bearing (64) on both sides of the reflector moving part (60) are respectively adapted to the second adapting groove (33) and the reflector guide groove (34) of the guide plate (30) to achieve; S1: The user applies force to the laser head (50) with his hand to flip it from the horizontal direction to the vertical direction. Since the fixed cylinder (71) on the laser head moving part (70) is sleeved on the outside of the input end of the laser head (50), the force of the laser head (50) acts on the fixed cylinder (71), and the guide arms (73) on both sides of the fixed cylinder (71) are respectively provided with a first fixed bearing (74) and a first movable bearing (75), wherein the first fixed bearing (74) is used as the center of the flipping circle of the laser head moving part (70) to rotate in the first adapter groove (31) of the guide plate (30), and the first movable bearing (75) revolves around the center of the circle along the laser head guide groove (32) of the guide plate (30). Then, the flipping movement of the laser head moving part (70) takes the first fixed bearing (74) as the center of the circle, and uses the first movable bearing (75) to slide in an arc along the laser head guide groove (32); S2: In the laser head moving part (70), the second connecting block (72) on the fixed cylinder (71) is hung with an elastic member (80), and the elastic member (80) is hung away from the second connecting block (72) and the first connecting block (62) on the reflector moving part (60). When the laser head moving part (70) is in a flipping motion, the elastic member (80) moves synchronously, and then the elastic member (80) drives the reflector moving part (60) to rotate together; S3: A second fixed bearing (63) and a second movable bearing (64) are provided on both sides of the reflector moving part (60), the second fixed bearing (63) is used as the center of the circle of the flipping of the reflector moving part (60) to rotate in the second adapter groove (33) of the guide plate (30), and the second movable bearing (64) revolves around the center of the circle along the reflector guide groove (34) of the guide plate (30), so that the flipping movement of the reflector moving part (60) takes the second fixed bearing (63) as the center of the circle and uses the second movable bearing (64) to slide in an arc along the reflector guide groove (34) until it slides from the starting end to the end of the reflector guide groove (34); S4: When the reflector moving part (60) rotates 45°, the reflector guide groove (34) will restrict it from continuing to rotate, but the laser head moving part (70) can continue to rotate to 90° by utilizing the 90° setting of the laser head guide groove (32) until it flips from the horizontal direction to the vertical direction. At this time, the elastic member (80) cooperates with the reflector moving part (60) to stretch the elastic member (80), so that the laser head moving part (70) is restricted to the 90° position and then fixed; S5: The reflector moving part (60) is in a 45° state, and the light path output of the light path output tube (20) is irradiated on the light path reflector (40) in the reflector moving part (60). The light path reflector (40) refracts the light path toward the laser head (50), thereby converting the horizontal light path into a vertical light path.
