HANDHELD POWER TOOL

摘要

The invention relates to a handheld power tool having a linear actuator (10) and a movable member (25), e.g. a blade, wherein the movable member (25) is directly connected to the actuator via a connecting rod (70), which pushes the movable member during a work stroke and pulls the movable member to a starting position during a return stroke. One end of the connected rod (70) is connected, via a concentric dual ball-and-socket joint, to the actuator as well as to a guide ring (80) that slides inside the cylindrical body (38) of the tool. Due to the arrangement of the invention, lateral and bending forces are taken up and transmitted to the body of the tool by the guide ring (80) without affecting the actuator. The ring (80) defines a sealed space that houses the actuator (10). An axial cavity of the connecting rod (70) partially houses the actuator (10) in the retracted position, thus reducing the length of the tool.

主权项

1. A handheld electric tool comprising an actuator acting by means of a connecting rod on a movable element configured to perform, under the action of the actuator, a work stroke in a first direction and a return stroke in a second direction, opposite the first direction,
in which the actuator is used to provide a work force during the work stroke and a return force substantially smaller than the work force during the return stroke, and in which the work force is transmitted by pushing the movable element, wherein the actuator is connected to the connecting rod via a first linkage of ball joint type and to a guide element via a second linkage of ball joint type, which is concentric with said first linkage.
