摘要： An electric cutting device includes: a pair of cutting blades for clamping and cutting an object; an electric motor; and a drive mechanism for operating the cutting blades. The drive mechanism includes a movement member movable in a predetermined direction by a driving force of the electric motor and converts movement of the movement member into an opening and closing operation of the cutting blades. The drive mechanism is configured to: when the movement member moves in the predetermined direction, cause the pair of cutting blades to move in a direction closer to each other; and after the pair of cutting blades come closest to each other, when the movement member further moves in the predetermined direction, cause the pair of cutting blades to move in a direction away from each other.

摘要： An electric cutting device includes: a pair of cutting blades clamping and cutting an object; an electric motor generating a driving force for operating the cutting blades; a control unit controlling the electric motor; an operation unit switched between an ON state and an OFF state by a user operation; and a determination unit. After the operation unit enters into the ON state and the pair of cutting blades start operating in a closing direction, the control unit is configured to: open the pair of cutting blades when the cutting of the object is completed while the operation unit is kept in the ON state; and stop closing the pair of cutting blades when the operation unit changes from the ON state to the OFF state at a timing before the cutting of the object is completed.

摘要： Un ensemble qui comporte :
- un outil électroportatif (100) comportant un moyen d'entrainement configuré pour déplacer deux lames ou deux mâchoires entre une position ouverte et une position fermée,
- un accessoire portable (200) destiné à être porté par l'utilisateur sur un membre distinct du bras de l'utilisateur portant l'outil,
- un moyen d'estimation d'une valeur représentative de la distance (D1) séparant l'accessoire portable et l'outil électroportatif, et en ce que les lames ou mâchoires sont déplacées ou maintenues en position ouverte à moins que chacune des conditions suivantes soient satisfaites :
- la valeur représentative de la distance (D1) séparant l'accessoire portable et l'outil électroportatif est inférieure à un seuil prédéterminé, dit seuil d'activation,
- la valeur représentative de la distance (D1) séparant l'accessoire portable et l'outil électroportatif est supérieure à un seuil prédéterminé, dit seuil de sécurité.-

摘要： A power-assisted cutting tool (100) includes a first cutting element (110) and a second cutting element (130) and a drive unit (170). The drive unit (170) selectively provides a supplemental motor (150) force to assist a movement of at least one of the first cutting element (110) and the second cutting element (130) to perform the cutting action. Moreover, a user interface (140) measures a hand force applied by a user, and generate a signal indicative of the measured hand force. And, the power-assisted cutting tool (100) includes a controller (190) communicably coupled to the user interface (140) and the drive unit (170), where the controller (190) receives actuates the drive unit (170). The power-assisted cutting tool (100) is characterized in that the controller (190) actuates the drive unit (170) such that a magnitude of the supplemental motor (150) force is at least one of a continuous variable or a discreet variable.

摘要： The present disclosure relates to the technical field of electric scissors, and in particular relates to a bidirectional driving mechanism for electric scissors blades and an electric scissors. The bidirectional driving mechanism for electric scissors blade includes a fixed seat, a driving gear, a rotating shaft member, an upper blade group and a lower blade. The driving gear and the rotating shaft member are arranged on the fixed seat, the lower blade and the upper blade group rotate around the rotating shaft member, an outer rack is arranged at a rear part of the lower blade, a front part of the upper blade group is an upper blade, a rear part of the upper blade group is a meshing block, and an inner rack is arranged at a rear part of the meshing block; and the inner rack and the outer rack are respectively meshed with both sides of the driving gear. When driving, the driving gear, the upper blade and the lower blade all rotate in a circumferential direction in the same plane, and the situation that the upper blade and the lower blade open outwards since the circumferential rotation of the gear and the circumferential rotation of the upper blade and the lower blade are perpendicular to each other is avoided, thereby improving the stability of the bidirectional driving mechanism of electric scissors blades, and making the bidirectional driving mechanism of electric scissors blades more durable.

摘要： The invention relates to a portable electric pruning shears (100) comprising:
- a longitudinal body (102) intended to be held by one hand of a user, called the holding hand,
- a cutting tool (110) arranged at a distal end (108) of said body (102),
- an electric motor (112) for operating said cutting tool (110), and
- a security system provided to protect said user;
wherein said security system comprises:
- an emitter (118) for emitting at least one electromagnetic wave and a receiver (124) for receiving at least one electromagnetic wave emitted by said emitter (118), one of which is embedded by said portable electric pruning shears (100) and the other one of which is intended to be worn by the other hand of the user, called the free hand (122), and
- a control unit (126) for acting on the operating of the cutting tool (110) as a function of the wave(s) received by said receiver (124). -
