The upper protective surface is installed on the upper side of the mask body, and a lower protective surface is installed on the lower side of the mask body. The motor box is installed on the upper side of the goggle lens. One end of the handheld rod has a screw hole and is fixed to the lower side of the mask body by a fixing screw. A switch is installed on the handle at the end of the handheld rod. The forehead pad is installed on the inner side of the mask body and is located on the lower side of the upper protective surface. The chin pad is installed on the inner side of the mask body and is located on the upper side of the lower protective surface. The goggle lens is fixed to one end of the motor mounted on the arm of the bracket. This technical solution also has the aforementioned technical problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4A new type of welding protective lens includes a protective sheet 1 and a filter 2 disposed on one side of the protective sheet 1, and a fixing frame 3. The bottom of the protective sheet 1 and the filter 2 are fixedly connected to the insert block 4. The bottom of the insert block 4 is movably inserted into the fixing frame 3. The fixing frame 3 has an installation port 17. The installation port 17 is provided to allow screws to pass through, so as to facilitate the installation of the fixing frame 3 onto the welding protective mask.

[0020] Please see Figure 1-4 A pressure frame 5 is provided above the fixed frame 3. The top of the protective sheet 1 is in close contact with the inner wall of the pressure frame 5, and the top of the filter 2 is in close contact with the inner wall of the pressure frame 5. The tops of the protective sheet 1 and the filter 2 are both fixedly connected with protrusions 14. The protrusions 14 are movably inserted into the pressure frame 5. The protrusions 14 are provided to stabilize and limit the installation of the protective sheet 1 and the filter 2.

[0021] Please see Figure 1-4 The fixed frame 3 has a motion groove 6 on its side, and a motion block 7 is provided in the motion groove 6. A connecting rod 8 is fixedly connected to the top of the motion block 7, and the top of the connecting rod 8 is fixedly connected to the pressure frame 5.

[0022] Please see Figure 1-4 A spring 9 is fitted on the surface of the connecting rod 8. One end of the spring 9 is fixedly connected to the fixed frame 3, and the other end of the spring 9 is fixedly connected to the moving block 7.

[0023] Please see Figure 1-4 A track 10 is fixedly connected to the groove at the bottom of the moving block 7. A card plate 11 is slidably connected to the surface of the track 10. A card block 12 is fixedly connected to one side of the card plate 11. The card block 12 is movably inserted into the fixed frame 3. A pull ring 15 is fixedly connected to the side of the card plate 11. An extension rope 16 is fixedly bolted to the pull ring 15. The pull ring 15 and the extension rope 16 are provided to facilitate the operation of the dragon card plate 11 by the staff.
