Gas combustor and safety switch thereof

A gas combustor, including:

• a housing used for enclosing a storage cylinder and a fuel gas controlling device disposed on a top end of said storage cylinder, a rear opening allowing a press button of an igniting device to protrude and a clamp slot allowing a safety switch to protrude are adjacently arranged on an upper portion defined on a back surface of said housing, and a front opening allowing a combusting device to be disposed is arranged on an upper portion defined at a front end of said housing;
• said fuel gas controlling device has a gas discharging press plate allowing said press button to be abutted and pivoted in said housing, a piezoelectric device is disposed in said press button, said piezoelectric device has an electric conducting wire extended to a flame nozzle of said combusting device and spaced from said flame nozzle with a gap;
• wherein said safety switch has a fastening unit and a locking unit abutted against a locking bolt formed on a bottom surface of said press button;
• said fastening unit has an accommodation chamber allowing said locking unit to be accommodated, and a swing arm having a latching hook is longitudinally disposed in front of said accommodation chamber with an interval;
• said locking unit has a main body accommodated in said accommodation chamber, a longitudinal spring is disposed between said main body and said accommodation chamber, and said main body has a push button protruded from a penetrated slot longitudinally formed on a rear wall of said accommodation chamber, and a locking hook protruded towards said latching hook;
• when said push button is not downwardly pushed, said locking hook is adjacently connected to said latching hook, and said locking bolt is abutted against said locking unit, thereby forming a non-pressing and locked status;
• when said push button is longitudinally and downwardly pushed, said longitudinal spring is compressed, and said locking hook at a top end of said main body is downwardly displaced along said latching hook for forming a mutual abutting status, so that said locking bolt is no longer abutted by said locking unit, thereby forming a pressing and unlocked status, said press button is able to be pressed for compressing said piezoelectric device, said gas discharging press plate is pressed and said swing arm is forwardly inclined so as to be deformed and moved toward a vertical column of the fastening unit, said locking hook is released from said latching hook, so that said locking unit is able to be upwardly displaced due to an energy releasing status provided by said longitudinal spring for enabling a top surface of said locking unit to be in contact with said locking bolt;
• wherein the fastening unit having the accommodation chamber, the vertical column, and the swing arm;
• the accommodation chamber, the vertical column, and the swing arm being integrally formed as a single piece;
• and the swing arm being located between the accommodation chamber and the vertical column.
