The tool has a motor-driven active head (1) moved by an electrical gear motor and installed at an upper end of a support sleeve (2) of the head. An auxiliary sleeve (4) is fixed on the support sleeve, placed below the head and placed at a distance from the head by forming an acute angle (alpha) with the support sleeve, in a proximal portion of the auxiliary sleeve. The auxiliary sleeve is shaped such that a free end of the auxiliary sleeve has a handle (5) provided at the level of a control handle (3) at a bottom part of the support sleeve, where the control handle controls the gear motor. The active head is selected from electrical pruners or chainsaw.従来のポータブル電動工具とは異なり、作業者の両手をポールの上に交互に置く必要がなく、より速く目的の枝の場所にアクティブヘッドを正確に誘導することができるポータブル電動工具を提供する。
