Abstract

L'invention concerne une mini-scie circulaire électrique, comprenant un corps de scie et des lames (2) de scie ; le corps de scie comprend un boîtier (1) et une boîte d'engrenages (5) située à l'extrémité avant du boîtier (1), le boîtier (1) étant pourvu en son sein d'un moteur électrique, et les lames (2) de scie étant disposées en rotation sur la boîte d'engrenages (5), une extrémité de sortie du moteur électrique étant en liaison par transmission avec les lames (2) de scie au moyen d'un élément de transmission dans la boîte de d'engrenages (5), le corps de scie étant pourvu d'une poignée (3), et la poussée de la poignée (3) sur le corps de scie agissant sur le côté inférieur du corps de scie lorsque la poignée (3) amène la scie circulaire à couper un matériau. Ladite mini-scie circulaire électrique s'appuie sur une conception séparant un corps de scie comportant en son sein un moteur électrique de la poignée, et en cours d'utilisation, la poignée peut être directement saisie par la main, ce qui empêche la transmission directe à la main de la vibration du moteur électrique, et améliore le confort de préhension de la mini-scie circulaire électrique ; en outre, la poignée est située sur le côté inférieur du corps de scie, ce qui facilite, au moyen de la poignée, l'application d'une force de coupe de matériau sur la scie circulaire, et permet d'avoir une taille compacte.
