Description




BACKGROUND OF THE INVENTION




The present invention relates to a detachable ring. More particularly, the present invention relates to a detachable ring which can be detached easily and quickly.




Referring to

FIGS. 1 and 2

, a conventional detachable ring has a main body


10


′, a safety collar


20


′ having an inner thread


21


′, and the main body


10


′ having a first end


101


′ having an outer thread


11


′ and a second end


102


′ having an outer thread


12


′. When the safety collar


20


′ engages with the first end


101


′ of the main body


10


′ and the second end


102


′ of the main body


10


′, the conventional detachable ring is closed. When the safety collar


20


′ disengages from the second end


102


′ of the main body


10


′, the conventional detachable ring is opened. If the first end


101


′ of the main body


10


′ does not match the second end


102


′ of the main body


10


′ precisely, the safety collar


20


′ cannot engage with both the first end


101


′ of the main body


10


′ and the second end


102


′ of the main body


10


′ at the same time. When the conventional detachable ring is opened, the safety collar


20


′ should disengages from both the second end


102


′ of the main body


10


′ and the first end


101


′ of the main body


10


′ slowly.
