Abrégé

The present invention relates to a system for increasing the safety of a portable electrical tool (10), comprising: a generator (40) of a radioelectric signal, which generator is electrically coupled to said user (1) so as to inject into the body of the user (1) said radioelectric signal (s(t)), said radioelectric signal (s(t)) then being emitted by said user (1) in the form of an electromagnetic signal; and the portable electrical tool (10), which is arranged to be borne by a member of the user and comprises: a machining member (4); a holding member (2); an actuator connected to the machining member (4); an antenna fastened to the machining member (4) and/or the holding member (2) and arranged to receive a radioelectric signal corresponding to the electromagnetic signal emitted by the user (1). A computing module (30) determines a distance between the user and the machining member and/or holding member on the basis of the electromagnetic signal received by the antenna, and modifies accordingly the speed of the actuator.

A power hand tool comprising: - a mobile element and a fixed element - a rotary actuator - a rod (100) arranged to move the mobile element under the action of the rotary actuator - an asymmetric angled bearing (1) arranged between the rod (100) and the rotary actuator. The asymmetric angled bearing (1) allows the rod (100) to make a radial movement (Θ) at least equal to ± 0.5°, thus allowing a reduction in the power consumption, noise and heating of the power hand tool. The asymmetric angled bearing (1) comprises an opening intended to receive a connecting screw (200), and the rod (100) comprises an opening intended to receive this connecting screw (200). The connecting screw (200) is therefore intended to link the asymmetric angled bearing (1) and the rod (100).

The invention relates to a handheld power tool (1), including: a mobile element (100) and a stationary element (102); a rotatable actuator; a ball nut (200); a ball screw (202) having a first end (202a) connected to the mobile element (100); and a universal joint (10, 12, 14) arranged so as to be driven by the rotatable actuator and so as to rotate the ball nut (200) on said ball screw (202) in order to move the ball screw (202), and thus the mobile element (100), relative to the stationary element (102). The universal joint can be advantageously retained inside two concentric spherical bearings (50a, 60a, 70a, 80a), thus making it possible to take up the axial forces in two directions. It is thus possible to eliminate any radial force on the ball screw (202) and have angularly variably rotational output.

Abrégé

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.
