disc 20 is provided at a center thereof with apositioning protrusion 21 and a throughhole 22 for receiving thepipe 151 of thegas cylinder 15. - The
switch 30 is defined with a locatinghole 31 for reception of thepositioning protrusion 21 of the adjustingdisc 20. Aleaf 32 is provided on theswitch 30, and at a portion of theswitch 30 connecting to theleaf 32 is defined with aprotrusive wall 33. - The
puller 40 is ‘V’ shaped, at a side of afirst end 41 of which is formed with aprotrusion 42, and on a surface of thefirst end 41 is defined ahole 43 for reception of thepipe 151 of thegas cylinder 15. - The
protrusion 42 of thepuller 40 is used to abut against theprotrusive wall 33 of theswitch 30. At both sides of a folding portion of thepuller 40 is defined with aleg 44 which is to be disposed between thereceiving groove 116 of thefemale cover 11 and thereceiving groove 121 of themale cover 12. Asecond end 45 of thepuller 40 insert in thereceiving space 13 formed by the female and the male covers 11,12. - The
spark lever 50 has ahandle portion 51, at both sides of thehandle portion 51 are defined with slidinggroove 52 which serves to engage with the slidingrail 115 of thefemale cover 11 and the slidingrail 124 of themale cover 12. Aduct 53 is formed at a side of thespark lever 50 for reception of the press-button 161 of theelectronic lighter 16, and at an outer side of theduct 53 anabutting portion 54 and astopping piece 55 are defined, thestopping piece 55 is to be abutted by thesecond end 45 of thepuller 40. - The safety lever 60, at a side of an end of which is provided with a
hooking block 61 that abuts against the outer surface of the throughhole 111. Thesafety lever 60 is slidably received in thethrough hole 111 of thefemale cover 11, and part of thesafety lever 60 serves to abut against theprotrusion 112 of thefemale cover 11. At a side of thesafety lever 60 is provided with astopping block 62 that is used to abut against theabutting portion 54 of thespark lever 50 from the bellow. At an end of thesafety lever 60 is defined with a receivinggroove 63 which corresponds to theflute 125 of themale cover 12. Thesafety lever 60 is further formed with arecess 64. - Two
elastic elements 70, one of which is received between thereceiving groove 63 of thesafety lever 60 and theflute 125 of themale cover 12, such that thesafety lever 60 can be pushed back to its original position by theelastic element 70 after being pressed by the user. Anotherelastic element 70 has an end fixed in therecess 64 of thesafety lever 60 and has another end abutting against the surface of thethrough hole 111 of thefemale cover 11, so as to enable a side surface of thesafety lever 60 withhooking block 61 to closely abut against thethrough hole 111. - Referring to
FIG. 5 , wherein thestopping block 62 of thesafety lever 60 abuts against the lower portion of thespark lever 50, such that thespark lever 50 cannot be pressed down before pressing thesafety lever 60, so as to form a safety protection of passive mode. On the other hand, the user can press thesafety lever 60 first so as to make theabutting portion 54 of thespark lever 50 avoid thestopping block 62 of thesafety lever 60. With the help of theelastic element 70 defined in thereceiving groove 63 of thesafety rod 60 and in theflute 125 of themale cover 12, thesafety lever 60 is able to return to its original position after being pressed by the user. - Referring further to
FIGS. 5 and 6 , thespark lever 50 cannot be pressed down before pressing thesafety lever 60 since thestopping block 62 of thesafety lever 60 abuts against the lower portion of thespark lever 50. Thereby the stoppingpiece 55 of thespark lever 50 is unable to press down thesecond end 45 of thepuller 40, and thefirst end 41 of thepuller 40 is unable to stand up. Such that thehole 43 of thepuller 40 cannot enable thepipe 151 to release gas out of thegas cylinder 15, and thus theprotrusive wall 34 of theswitch 30 cannot be switched over cause it is pushed by theprotrusion 42 of thepuller 40. Therefore, theswitch 30 will not be switched over and no gas will be released out of thegas cylinder 15 in case that the user inadvertently touches theswitch 30. - Referring to
FIGS. 7-9 , to operate the gas gun, initially the user needs to push thesafety lever 60 towards thespark lever 50 so as to separate the hookingblock 61 from the outer surface of the throughhole 111 of themale cover 11, then keep pressing on thesafety lever 60 and simultaneously presses thehandle portion 51 of thespark lever 50, so as to make the abuttingportion 54 of thespark lever 50 avoid the stoppingblock 62 of thesafety lever 60. In this case, the stoppingpiece 55 of thespark lever 50 presses down thesecond end 45 of thepuller 40 and makes thefirst end 41 of thepuller 40 stand up, such that thehole 43 of thepuller 40 can enable thepipe 151 of thegas cylinder 15 to release gas and enable theinjection head 14 to light the gas. At this moment, the gas will be turned off if the user releases thespark lever 50 to make thepuller 40 return to its original position. Or if want to keep lighting the gas, the user can press thespark lever 50 first and turn theswitch 30, such that theprotrusive wall 34 of theswitch 30 is caused to keep rotating counterclockwise until it abuts against the lower portion of thefirst end 41 of thepuller 40. In this way, thepipe 151 of thegas cylinder 15 is pulled constantly in thehole 43 of thepuller 40, so as to release the gas constantly. - While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
