1. A handheld work apparatus comprising:
a motor;
a battery for supplying the motor with energy;
a transmission shaft;
a tool;
a guide tube having a front longitudinal end and a rear longitudinal end;
a housing;
a first anti-vibration element;
said motor being configured to drive said tool via said transmission shaft;
said transmission shaft being received in said guide tube;
said motor being disposed in said housing;
said tool being disposed on said front longitudinal end of said guide tube;
said housing being disposed on said rear longitudinal end of said guide tube;
said housing at least partially encompassing the guide tube;
said guide tube projecting from said housing;
said guide tube at an entry point extending into said housing in a longitudinal direction;
said first anti-vibration element being disposed such that said first anti-vibration element acts in a vibration-decoupling manner between said housing and said guide tube;
said first anti-vibration element being disposed on a side of said motor facing said tool;
a second anti-vibration element connecting said motor to said housing in an at least indirectly vibration-decoupled manner;
said battery being connected to the housing in such a manner that the battery, conjointly with the housing, via said second anti-vibration element is vibration-decoupled from the motor; and,
wherein said second anti-vibration element is disposed at an element spacing, measured in the longitudinal direction, from said first anti-vibration element; said first anti-vibration element in relation to the battery has a battery spacing measured in the longitudinal direction; and, said element spacing is at least 50% of said battery spacing.
