[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Reference Figures 1-9 A handheld laser welding machine that prevents metal spatter includes a handheld laser welding machine body 1 and a mounting cylinder 2. The mounting cylinder 2 is installed on the outer side of the end of the handheld laser welding machine body 1. It also includes: a connecting ring 3, a support plate 4, two A-type protective covers 5, an angle adjustment part 6, and a depth adjustment unit 7.

[0037] The connecting ring 3 can slide on the outside of the mounting cylinder 2. The upper side of the support plate 4 is provided with mounting hole A. The connecting ring 3 is located inside mounting hole A. The lower side of the support plate 4 is equipped with a protective shell 8.

[0038] The depth adjustment unit 7 is located between the connecting ring 3 and the mounting cylinder 2. The depth adjustment unit 7 has four springs 71. The connecting ring 3 has four sliding grooves on its inner side. A guide shell 72 slides inside the sliding grooves. A driving block 73 slides inside the guide shell 72. The driving block 73 has a through hole on its upper side. A guide rod 74 slides inside the through hole. The driving block 73 has an A positioning groove on its outer side and a B positioning groove on its inner side. An A guide strip 79 slides inside the A positioning groove, and a B guide strip 710 slides inside the B positioning groove. The A guide strip 79 is fixedly connected to the inner side of the guide shell 72, and the B guide strip 710 is fixedly connected to the outer side of the mounting cylinder 2. The guide rod 74 is located inside the springs 71 and is fixedly connected to the inner side of the guide shell 72. The guide shell 72 has two guide grooves on its outer side. A C guide rod 710 slides inside the guide grooves. Connecting block 75 (C) is fixedly connected to connecting ring 3 and driving block 73.

The positioning blocks 77 are fixedly connected to the outer side of the mounting cylinder 2. When the positioning nuts 78 move to one side of the positioning blocks 77, they work with the sliding rods 76 to limit the connection ring 3, preventing the connection ring 3 from moving out of the mounting cylinder 2 and improving the stability of the device.

[0040] The support plate 4 has two B mounting holes on its upper side. The A protective cover 5 is installed inside the B mounting holes. The protective shell 8 has C mounting holes on both the front and rear sides. The B protective cover 9 is installed inside the C mounting holes. Both the A protective cover 5 and the B protective cover 9 are made of transparent material, allowing personnel to see the processing area and protecting their eyes, thus improving the safety of the equipment.

[0041] Angle adjustment unit 6 is located between connecting ring 3 and support plate 4. Angle adjustment unit 6 includes a rotating ring 61, which can rotate inside the A mounting hole. The rotating ring 61 has positioning rings 62 on both the upper and lower sides, and the positioning rings 62 are fixedly connected to the inside of the A mounting hole. The rotating ring 61 has an A support ring 63 inside, and two A connecting blocks 65 rotate on the outside of the A support ring 63. The A connecting blocks 65 are fixedly connected to the inside of the rotating ring 61. The connecting ring 3 has two B connecting blocks 66 rotate on the outside, and the B connecting blocks 66 are fixedly connected to the inside of the A support ring 63. The two A connecting blocks 65 and the two B connecting blocks 66 are placed in a cross shape on the horizontal plane.
