Folder in one of them embodiment, where first separation unit between plane and the second connecting rod axial direction Angle is 145 °~155 °.
In one of them embodiment, the second separate section radian is 13 π/36~15 π/36, the third point Radian from portion is π/36~2 π/36.
In one of them embodiment, the radius of second separation unit is 0.5~1mm, the third separation unit Radius is 10~11mm.
In one of them embodiment, the separator body with a thickness of 0.07mm~0.09mm.
Compared with prior art, the invention has the advantages that
1, using technical solution of the present invention, the end of the room corner separator is in arcuation, can be with the natural space in room angle Radian fits, and can be precisely separated room angle;
2, using technical solution of the present invention, separator after goniosynechia at separation one, laterally along room angle radian to point Opening extreme direction sliding from device, i.e., the separable room angle for closing on adhesion, improves separative efficiency;
3, using the further technical solution of the present invention, the link rod part of handle portion meets the design of wrist mechanics, has higher Operational comfort.
