Near described the handle the wideest rear end (wide) to 22mm, and just in time before N shape junction surface, taper to narrow 8 (width is approximately 9mm).Narrow of described handle forms the second deflection band.

The shape approximation of the head of this device is an isosceles triangle, but has curved edge and bight.Locating with the junction surface of handle, about 15mm is wide for head, and at leading edge 13 places, width is approximately 45mm.

Deflection band 5 in head is by mainly being that elastomeric zone provides.The head general curved of this regional cross device, and this head part is divided into the front and rear part.On the lower surface of head, the elastomer zone forms thin layer 14, and the center that this thin layer 14 extends across rear portion 3 arrives the junction surface.

Above-mentioned two flexible bands form with the length approximate vertical of handle and with the deflection axis of fin almost parallel.

Thin elastomer layer arrives the downside of the front portion 4 of head continuously, and described two elastomer fins cross out from this downside.

Head 2 has the curved side 12 around its lower surface.These curved side play the effect of barrier, below remaining on the composition that will remove, and prevent that composition from contacting user's hand.

In use, the user keeps described device by handle, normally it is grasped in palm or the finger, perhaps uses grasping groove 10 to keep this device by finger and thumb.When being desirably in the position (as the leg rear) that is difficult to touch when using this device, can adopt back one mode.No matter adopt which kind of mode to keep this device, fin all is placed on the skin, and pulls back this device on skin; That is, head is positioned at after the handle.Power is passed to the front portion 4 of head, particularly head from handle by deflection band and junction surface 6.Described two heads 3 and 4 can center on the relative to each other hinged rotation of deflection band 5, thereby in use, they no longer form continuous surface.When observing from the side, part 3 and 4 forms obtuse angle (referring to Fig. 5) together.

Alternatively, the user can be at place, the side at N shape junction surface 6 or the rear portion by head this device is remained between thumb and the forefinger, thereby walk around deflection band 8.This can allow closely moving of control device, and/or more firmly exerts pressure to skin.

In use, described device is progressive around the deflection by narrow 8 deflection band that limits; The stable power that increases makes deflection stably increase.Originally the deflection that anterior and head centers on deflection band 5 be progressive.Heretofore, the remote edge of fin has become major part or the only part that fin contacts with skin.Yet under the effect of critical force, mobile status is swung or be turned in the front portion suddenly, and remainder from the head extends upward, as shown in Figure 5.The rear wall of fin is major part or the only part that fin contacts with skin now.Roughly suppressed further deflection.On the contrary, the further deflection by fin has adapted to applying more basically.

Thereby the first embodiment of the present invention has built-in release mechanism, and this release mechanism makes and causes the danger of damage to minimize owing to apply excessive power to skin; When critical force, anterior " upset " to its raised position, thus the contacting of change skin and fin.

This device has enough elasticity, thereby it can return to its original shape when not re-using.

Second embodiment shown in Fig. 6 also has handle 41 and head 42, and this head is divided into front portion 46 and rear portion 60 by deflection band 52.Even when not having operative installations, the front portion 46 of head also tilts with respect to rear portion 60.This front portion is the bluff body of substantially elliptical.It has the flat bottom surface that carries four straight, parallel fins 48.This front portion is connected to the rear portion by the wedge-shaped part of being made by elastomeric material 52, and this wedge-shaped part is represented the first deflection band 52 of this device.Forming section 58 is arranged on handle, and this forming section is designed to finger or above thumb cosily is resisted against.In cephalic position, the dead astern of forming section 58, be formed with the plastic areas that profile is alphabetical N.The right side flap of this occiput 60 extends to elastomer wedge-shaped part 52 always.In the space or recess that limit by alphabetical N forming section, has the wedge-shaped part of making by elastomeric material 62,64.Thereby this device has two bending points, and one is N shape zone, and another is an elastomer wedge-shaped part 52.
