[0027] To prevent space constraints during the repair and replacement of internal components of the laser body 1, a damping spring rod 18 is provided on the bottom surface of the mounting base 12, with the bottom end of the damping spring rod 18 abutting against the inner bottom surface of the laser body 1. A control main board 13 is screwed to the top surface of the mounting base 12, and a main board cover plate 16 is slidably connected to the surface of the mounting base 12. Cover plate grooves 17 are formed on both sides of the mounting base 12. The front cross-section of the main board cover plate 16 is U-shaped, and the end of the main board cover plate 16 is slidably located inside the cover plate groove 17. The mounting base 12 serves as a medium for connecting the control main board 13 and the damping spring rod 18, preventing damage caused by direct connection between the damping spring rod 18 and the control main board 13. The main board cover plate 16 is connected to the control main board 13 through the cover plate groove 17. To protect the optical module component 14 on the surface of the control motherboard 13 and prevent it from being directly contacted and worn by the damping spring rod 18 due to the rebound of the damping spring rod 18, a cover plate limiting block 4 is provided on the bottom surface of the sealing cover plate 3.

The length of the motherboard cover plate 16 is the same as the length of the mounting substrate 12. When the sealing cover plate 3 slides into contact with the surface of the laser body 1, the bottom cover plate limiting block 4 abuts against the top surface of the motherboard cover plate 16, causing the motherboard cover plate 16 to be pressed down. At this time, the damping spring rod 18 is slowly contracted under pressure, so that after the sealing cover plate 3 is connected, the damping spring rod 18 is in its shortest contracted state. Figure 3 As shown, the guide groove 5 has a T-shaped cross-section. Therefore, even if the laser body 1 is subjected to vibration, the control main board 13 will not shake due to the limitation of the shortest contraction of the damping spring rod 18 and the limitation of the guide groove 5, and will remain stable. After the sealing cover plate 3 is removed, the damping spring rod 18 fully recovers its original length, driving the mounting base plate 12 and its entire top connecting structure to slowly approach the top of the laser body 1. When the damping spring rod 18 recovers to its initial original length, the bottom surface of the mounting base plate 12 is exactly coplanar with the top surface of the laser body 1. Figure 4 As shown, at this time, the motherboard cover 16 is slid open along the cover slide groove 17, and the optical module component 14 on the surface of the control motherboard 13 can be inspected. At this time, since the control motherboard 13 pops out, it will not be obstructed by space during inspection and replacement, which facilitates the inspection and quick replacement of parts.

[0028] In the use of connecting the laser main body 1 with the external connection line 9, both ends of the laser main body 1 are provided with a connection interface 8, and the surface of the control mainboard 13 is provided with an optical module element 14. A flexible transmission pipeline 15 is arranged between the optical module element 14 and the connection interface 8. A part of the length of the flexible transmission pipeline 15 is reserved to keep the connection when the control mainboard 13 moves with the spring rod, to adapt the distance. The external surface of the connection interface 8 is threadedly connected with a threaded positioning cap 11. The end of the connection interface 8 is clamped with a line connector 10. The external surface of the line connector 10 is provided with threads connected with the threaded positioning cap 11. The end of the line connector 10 is connected with the end of the connection line 9. The end of the laser main body 1 is provided with the connection interface 8 to connect the connection line 9. After the connection line 9 is inserted into the connection interface 8 through the line connector 10 at the end, the threaded positioning cap 11 on the surface of the connection interface 8 is rotated to externally position the connection position of the connection interface 8 and the line connector, to increase the stability of the connection of the line connector 10, and effectively prevent the connection from falling off. Specific embodiment two:

[0030] Reference Figures 1-6 According to the content in the above specific embodiments, the following content is further disclosed:

[0031] The whole signal access and transmission process of the laser main body 1 is as follows:

[0032] External signal access: external optical signals or electrical signals first enter the laser main body 1 through the connection line 9. These connection lines 9 are usually optical fibers or coaxial cables, etc., depending on the signal type and transmission requirements;

[0033] Line connector 10 and connection interface 8 docking: the end of the connection line 9 is the line connector 10, which is designed to be accurately clamped into the connection interface 8 at both ends of the laser main body 1. This clamping design ensures stable transmission of signals and reduces signal loss;

[0034] The role of the flexible transmission pipeline 15: after the line connector 10 is docked with the connection interface 8, the signal enters the inside of the laser main body 1 through the flexible transmission pipeline 15 inside the connection interface 8. The flexible transmission pipeline 15 plays a key role here, which not only protects the integrity and stability of the signal during transmission, but also adapts to the complex spatial layout inside the laser main body 1, to ensure that the signal can smoothly reach the optical module element 14 on the control mainboard 13;

[0035] Signal conversion and transmission: on the control mainboard 13, the optical module element 14 is responsible for converting the received optical signals or electrical signals for subsequent processing. The converted signals are further processed and transmitted through the circuit on the control mainboard 13;

[0036] Internal processing and output: After processing by the control motherboard 13, the signal is used to adjust the output characteristics of the laser, such as wavelength, power, etc. Finally, the adjusted optical signal is output to the outside through the emission device inside the laser main body 1. Specific embodiment three:

[0038] Referring to Figures 1-6 , according to the content in the above specific embodiments, the following is further disclosed:

[0039] In actual use, the flexible transmission pipe 15 further includes the following:

[0040] The flexible transmission pipe 15 is designed as a tubular structure that can be flexibly bent and stretched inside the laser main body 1 to adapt to the compact and complex spatial layout inside the laser main body 1. It is usually composed of multiple layers of materials, including an inner layer of optical fiber or conductive material, a middle layer of protective layer, and an outer layer of wear-resistant layer;

[0041] The optical fiber part is used to transmit optical signals, ensuring signal integrity and low loss. For electrical signal transmission, conductive materials such as copper wire or silver-plated wire can be used;

[0042] The protective layer is used to protect the optical fiber or conductive material from mechanical damage and chemical corrosion, while providing certain insulation performance;

[0043] The wear-resistant layer is used to enhance the wear resistance of the pipe and prolong its service life.

[0044] For optical signal transmission, the optical fiber part in the flexible transmission pipe 15 usually uses high-purity silica as the core material, and is coated with a low-refractive-index cladding material such as fluoride glass, plastic, etc. to form total reflection conditions, ensuring that the optical signal does not leak when transmitted inside the optical fiber.

[0045] Conductive material: For electrical signal transmission, conductive materials such as copper, silver, or copper-silver alloy are widely used due to their good electrical conductivity and stability. These materials can effectively reduce signal attenuation and distortion during transmission;

[0046] Protective layer and wear-resistant layer material: The protective layer and wear-resistant layer are usually made of high-temperature-resistant, corrosion-resistant, and wear-resistant polymer materials such as polytetrafluoroethylene PTFE and polyimide PI to ensure that the flexible transmission pipe 15 can maintain stable performance in harsh working environments.
