切断した断面図に相当する。動作を略説すると次の通り
である。FIG. 6 corresponds to a cross-sectional view of the guide body (02) shown in FIG. 1 taken along the line r-t'. The operation is briefly explained as follows.
把手Ａ （８１）、把手Ｂ （６２）を押圧することに
より、支点（６７）を中心に、開き戸（６３）（６４）
が開き、囲繞部（６６）は開放され、端子部が囲繞され
る。By pressing handle A (81) and handle B (62), the hinged door (63) (64) is opened around the fulcrum (67).
is opened, the surrounding portion (66) is opened, and the terminal portion is surrounded.
把手Ａ （６１）、把手Ｂ （６２）の押圧を止めると
