[0002] The background technology of a handheld laser welding head with a safety device mainly involves the field of laser processing technology, especially the improvement and safety enhancement of laser welding equipment. With the development of the manufacturing industry, the requirements for welding technology are getting higher and higher, especially in terms of improving production efficiency, ensuring operational safety and environmental protection. Although traditional welding technology has been widely used in industrial production, it has problems such as low efficiency, great safety hazards and serious environmental pollution. Laser welding technology has gradually become an important development direction in the field of welding due to its advantages such as high precision, high efficiency and low deformation. According to the existing technology, the temperature of the end of the laser welding head is extremely high. If it is not stored properly after use at high temperature, it is very easy to bump against the ground, etc., causing damage and affecting subsequent use. Through technological innovation, the welding process is efficient, safe and environmentally friendly, providing a more ideal welding solution for the modern manufacturing industry.

[0003] Handheld laser welding heads are indispensable tools in modern industrial manufacturing. They provide high-precision and high-efficiency welding capabilities. However, since the optical and electronic components inside the laser welding head are relatively sensitive and fragile, they require regular maintenance and occasional replacement. Most existing laser welding head designs often do not fully consider the convenience of repair and replacement, resulting in increased maintenance costs and extended equipment downtime. Therefore, we propose a handheld laser welding head with a safety device to solve this problem. Utility Model Content
