Gas burner having synchronous ignition and gas supply functions

A gas burner having synchronous ignition and gas supply functions, comprising:

• a housing connected to a gas storing tank and a burning device, said gas storing tank having a gas outlet nozzle connected to a gas supply device to deliver fuel gas to said burning device, said housing having a top portion with a housing chamber containing a piezoelectric ignition device, one side being provided with a lock-shaped hole with a retaining device;
• a plurality of air vents formed in said housing for entry of air into said housing and through a clearance between said gas supply device and said burning device into said burning device along with the fuel gas;
• said piezoelectric ignition device having a push key;
• a lead wire of the piezoelectric ignition device extending to said burning device;
• said retaining device including a sliding piece and a driven piece butt joined on sides of said lock-shaped hole, with a press button having a button spring;
• a connecting groove at a rear end of said sliding piece connecting said gas outlet nozzle, a top portion thereof being provided with a transverse block that abuts against a push piece, a front end thereof being provided with a piece shaft connected with a shaft spring;
• and said driven piece having a piece hole corresponding to said press button, whereby when said press button is pushed, said piezoelectric ignition device is compressed so that said transverse block is pushed by said push piece to cause said sliding piece and said driven piece to be synchronously displaced and the shaft spring to retract, said press button entering a wider portion of said lock-shaped hole via a narrower portion, said button spring stretching to cause said press button to be retained in said lock-shaped hole and extend from said piece hole, a gas nozzle being pulled out by said connecting groove for supply of fuel gas via said gas supply device to said burning device, sparks generated by said lead wire igniting the fuel gas mixture.
