This creation is a kind of bristle fixed structure for having angle of related what, is mainly that the body of rod is deliberately bent to an angle or arcuation, so that body of rod clip is fixed on and be not easy to loosen in positioning region, brush uses upper safety between You Xiao Ti Noboru tooth. It is mainly to be made of bristle, the body of rod, positioning region and lever, the front end of the position what body of rod is provided with bristle, it is brushed between the more general tooth of the length of the positioning region short, and in order to enable the body of rod to be tightly disposed in positioning region, deliberately the body of rod in bristle Hou side is suitably located to bend a clip section, enable the body of rod and positioning region it is firm engage, not easy glide, the body of rod can be fixed in positioning region really, avoid the body of rod using when loosen and safety between clip what slot, in Ke Ti Noboru bristle use.本創作係有關於一種具角度之刷毛固定結構，其主要係將桿體刻意彎折一角度或弧狀，使桿體能卡掣固定在定位部內不易鬆脫，有效提昇牙間刷使用上的安全。其主要係由刷毛、桿體、定位部及握柄所組成，位於桿體之前端設置有刷毛，該定位部的長度較一般牙間刷短，而為了使桿體能緊密設置在定位部內，刻意在刷毛後方之桿體適當處彎折一卡掣段，使桿體能與定位部穩固嚙合、不易滑移，能確實將桿體固定在定位部內，避免桿體使用時鬆脫而卡夾於齒縫間，可提昇刷毛使用上的安全性。
