When the pin 52 is locked with the stopper Ge, the bottle 511 is removed from the lock spring (54) and becomes as shown now. In addition, bottle 6I) and lock winter bushing L54) k;
When the rotating shaft (L) rotates in the opposite direction and the lamp wick (6) descends, it fully engages.

In addition, in this embodiment, when the lamp wick (6) is lowered, the switch force and Muro 2 are reversed, and when the lowering is completed, the 6 pieces (524
) comes into contact with the stopper (50), but since the strip <60 is made of rubber or the like, the amount of descent of the wick (6) is reduced.

Furthermore, in this embodiment, since a forced wick lowering knob/trowel is provided on the rotating shaft (II), tar etc. may adhere to the wick (6), and the wick lowering spring (27) may not be able to handle the wick with just the stored force. (
If the lamp wick (6) is not completely lowered, the lamp wick (6) can be lowered completely by operating the knob 6. ,
