This creation, which includes at least, an ontology,In-between place is formed with the through hole of closed,And what extends to form one towards outside protrusion through hole peripheral and collects shape extension,And what through hole periphery side is formed with several spleniums,To cause faeces bag sack edge compression zone pinching to position Hou,And the other parts of faeces bag is enable to store in accommodating what extension; FurthermoreThe appropriate place of ontology is respectively formed with fixation hole and lower through-hole,And the fixation hole and lower through-hole system position what through hole it is not ipsilateral,With cause fixing piece group and a left side,Group is set at what fixation hole and lower through-hole right leg binding belt respectively; Also,Fixing piece group include one with solid standard shaft frame piece,And it can be nested with the external member at the above-mentioned standard shaft of blocking what,Wherein,The frame piece can be divided into base portion and standard shaft,And base portion middle has extended to form standard shaft outward,The standard shaft is equipped with concave ring,The concave ring is connected to cone cell fastening part,So that standard shaft is passing through Hou in the axis hole to the axle sleeve of external member,At the vertical core that can enable the axle sleeve of the fastening part blocking what external member of standard shaft,And make on the sandwiched what ontology of axle sleeve of the base portion and external member of frame piece; In addition,The ora terminalis of Beam End band is formed with hollow form circle portion,The system, circle portion can group set in what fixing piece group,And Beam End band then may pass through regulating part,And by regulating part by Beam End band be distinguished into one by Beam End band middle section to closed formed between regulating part space region,And another circle portion by regulating part to Beam End band and group
