Abstract

La direction dans laquelle les batteries rechargeables (80a, 80b) sont coulissées et montées par rapport aux première et seconde parties de montage pour batteries (60a, 60b) est définie selon une direction perpendiculaire par rapport à la direction d'extension de la forme de saisie d'une partie de manche verticale (35) et d'une partie de manche horizontale (36). En outre, deux parties de montage pour batteries, à savoir, la première et la seconde partie de montage pour batteries (60a, 60b) sont mises en oeuvre, de sorte que deux batteries rechargeables (80a, 80b) peuvent être montées. Ainsi, il est possible de satisfaire à une exigence de réglage de tension à puissance élevée ou de réglage de capacité d'alimentation électrique élevée quand une souffleuse (10) est utilisée.
