When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Example one

In the embodiment, referring to fig. 1, the argon arc welding gun head of the present invention includes a gun handle 10, a gun head main body 20, and an eye protection device; the gun handle 10 is arranged on one side of the gun head main body 20; the eye protection device is rotatably arranged on the gun head main body 20; the eye protection device comprises a clamping ring 30, a connecting rod 40, a lens shell 50 and an eye protection lens 60 clamped in the lens shell 50; the clamping ring 30 is rotatably arranged on the gun head main body 20, one end of the connecting rod 40 is connected with the mirror shell 50, and the other end of the connecting rod is welded and fixed with the clamping ring 30. The argon arc welding gun head is directly provided with the eye protection device, so that an eye protection helmet is not needed to be worn, the welding is convenient and rapid, and the operation is more convenient.
