Abstract
(EN)
A power tool comprises a head shell (11) and a machine shell (12). A motor and a driving mechanism are provided inside the machine shell (12). An output shaft (14) extends from the head shell (11). By the driving of the motor and the torque transmission of the driving mechanism, the output shaft (14) performs a rotationally oscillating movement about its axis (L). Wherein, an elastic element is provided between the head shell (11) and the output shaft (14). The elastic element can effectively absorb the vibration occurred on the output shaft (14) and the vibration transferred to the output shaft (14) by the non-symmetrical balance attachments, thus weakening the vibration transferred to the head shell (11) by the output shaft (14), greatly improving the vibration problem occurred in the process of the use of a user, and improving the operating comforts.

Un outil motorisé comprend une conque de tête (11) et une coque de machine (12). Un moteur et un mécanisme d'entraînement sont disposés à l'intérieur de la coque de machine (12). Un arbre de sortie (14) s'étend depuis la coque de tête (11). Grâce à l'entraînement du moteur et à la transmission de couple du mécanisme d'entraînement, l'arbre de sortie (14) effectue un déplacement oscillant rotatif autour de son axe (L). Un élément élastique est disposé entre la coque de tête (11) et l'arbre de sortie (14). L'élément élastique peut efficacement absorber la vibration produite sur l'arbre de sortie (14) et la vibration transférée vers l'arbre de sortie (14) par des accessoires d'équilibre non symétriques, affaiblissant ainsi la vibration transférée à la coque de tête (11) par l'arbre de sortie(14), améliorant considérablement le problème de vibration survenant dans le processus de l'utilisation d'un utilisateur, et améliorant le confort de fonctionnement.
