162


of the electric arc generator


16


, one electrode of the electric arc generator


16


is connected to the lighting section, and the other electrode of the electric arc generator


16


is connected to the tube


12


.




Referring to

FIG. 2

, an arresting section


2


is appropriately situated between the press section


19


and the gas receptacle


14


; the arresting section


2


has a body


20


that is pivotably situated in the casing section


10


, an actuating rod


22


aligned with the body


20


is disposed along the outer side of the casing section


10


, one end of the actuating rod


22


is inserted through the casing section


10


and conjoined to the body


20


, an elastic component


202


is installed at one side of the body


20


, and one end of the elastic component


202


is mounted inside the casing section


10


; when the actuating rod


22


is released, the rebound force of the elastic component


202


causes the actuating rod


22


to return to its original position; a connecting rod


24


is movably conjoined to one end of the body


20


near the press section


19


, a second elastic component


242


is installed on the connecting rod


24


and utilized when the connecting rod


24


is depressed, the second elastic component


242


restoring the connecting rod


24


back to its original position.




When the actuating rod


22


of the arresting section


2


is deployed, the connecting rod


24


is moved to the upper edge of the gas receptacle


14


and when the press section


19


is depressed, the connecting rod


24


impels the push plate


146


and causes gas contained in the gas receptacle


14


to flow through the soft tubing


44


to the lighting section, while the press section


19


is moved against the starting section


162


, causing the electric arc generator


16


to discharge a spark that ignites the gas at the lighting section to complete the lighting operation; when the unmoved actuating rod


22


is again deployed by the press section


19


, it is capable of causing the electric arc generator


16


to discharge a spark, but is incapable of inducing gas to flow from the gas receptacle


14


into the soft tubing


144


and thus the ignition process at the lighting section cannot be complete, though safety is ensured.




However, the inventor of the invention herein discovered that the lighter


1


is not easy to operate during actual usage due to the actuating rod


22


which cannot move the connecting rod


24


to the upper edge of the gas receptacle


14


such that when the press section


19


is depressed, only a spark is discharged by the electric arc generator


16


and the ignition process cannot be completed, resulting in numerous inconveniences and difficulties. As such, since the lighter


1


is ensured to be safe but is not convenient to utilize, effectively overcoming the drawbacks would certainly be welcomed by consumers.




SUMMARY OF THE INVENTION




Although the conventional lighter is of ensured safety but has the drawback of inconvenient utilization, the inventor of the invention conducted extensive research and testing, culminating in the successful design and development of the lighter structure of the invention herein which is comprised of a casing having a lighting section at one end; a push button at the other side; a safety lock section situated at the end of the casing opposite from the push button and another safety lock section situated at the end of the casing opposite from the movement area of the push button; a movable section disposed between the push button and the casing, with the movable section and the push button capable of moving together such that the push button slides on the movable section; and an elastic component situated on the outer lateral surface of the movable section opposite from the safety lock section, with the other end of the elastic component connected to the push button; depressing the push button causes the push button to slide along the movable section and when the safety lock section separates from the other safety lock section, the push button can be depressed such that the push button impels the movable section towards the electric arc generator and the pull plate, causing the pull plate and the electric arc generator to operate simultaneously and the gas in the gas receptacle to flow through the guide tube to the lighting section, while the electric arc generator discharges a spark that ignites the gas at the lighting section; therefore, the user only needs one hand to hold the lighter and use a single finger to actuate the safety lock section to efficiently perform the lighting operation and, furthermore, in a manner that is convenient and ensured to be safe.
