Title
(EN) HANDHELD ELECTRIC POWER TOOL
(FR) OUTIL ÉLECTRIQUE PORTATIF
Abstract
(EN)
According to a first aspect of the invention a handheld electric power tool comprising a drive train assembly (100) arranged along a longitudinal axis of the tool, a housing (10) adapted to receive the drive train assembly and a retaining ring (20) is provided. Wherein the housing comprises a first portion (11) and a second portion (12) adapted to form the housing (10) including a conical outer surface portion (10a) having a substantially circular cross section, and wherein the retaining ring comprises an inner surface (21 comprising a conical inner surface portion (21a) adapted to cooperate with the conical outer surface portion (11a) such that a force is exerted on the first and second housing portions by means of the ring as the conical inner surface (21a) and the conical outer surface (10a) are axially displaced with respect to one another, thereby urging the first and second housing portion together.

Un premier aspect de l'invention concerne un outil électrique portatif comprend un ensemble train d'entraînement (100) agencé le long d'un axe longitudinal de l'outil, un boîtier (10) conçu pour recevoir l'ensemble train d'entraînement et un anneau de retenue (20). Le boîtier comprend une première portion (11) et une seconde portion (12) conçues pour former le boîtier (10) comprenant une portion de surface externe conique (10a) ayant une section transversale sensiblement circulaire et l'anneau de retenue comprenant une surface interne (21) ayant une portion de surface interne conique (21a) conçue pour coopérer avec la portion de surface externe conique (11a), de sorte qu'une force soit exercée sur les première et seconde portions de boîtier au moyen de l'anneau tandis que la surface interne conique (21a) et la surface externe conique (10a) sont déplacées axialement l'une par rapport à l'autre, poussant ainsi les première et seconde portions de boîtier ensemble.
