    摘要： A locking assembly (1) for blades for motorized scissors (2), of the type comprising a main body (3) which defines a grip and houses respective movement elements and an actuation motor, a fixed blade (4) which is integral with the body (3), and a moving blade (5) which is pivoted to the body (3) in substantial juxtaposition with the fixed blade (4) and is functionally associated with the movement elements. At the pivoting axis of the moving blade (5) to the main body (3) and to the fixed blade (4), it comprises: a pivot (7) provided with an externally threaded end portion (8) and with a threaded longitudinal internal channel (9), in which the internally and externally threaded hollow end portion (8) is slotted by a through transverse cut (10) arranged on a diametrical plane of the pivot (7); a tightening element (11) provided, in a through hole thereof, with a female thread with shape and dimensions complementary to those of the threaded end portion (8) for screwing thereon; a locking screw (12) matching the internal threading of the longitudinal channel (9) of the end portion (8) of the pivot (7) for screwing therein.

    摘要： The present disclosure discloses a signal generator based on inductance characteristics of an element, an electric shearing tool, and a shear opening degree control method for an electric shearing tool, and relates to the technical field of electric shearing tools. A changeable inductance value of an inductance type transducer is obtained through a change in a relative position between a triggering member and the inductance type transducer. The inductance value is increased or decreased linearly, so that a control processor can precisely obtain relative position information between the triggering member and the inductance type transducer according to linear changes of the inductance value, thereby obtaining position information of a blade travel control member. Each position point can be mapped to current positions of blades. Furthermore, since the inductance type transducer and the triggering member are used for control and detection, the following problem can be avoided during mounting: the production efficiency is affected because an S pole or an N pole of a magnet needs to be confirmed during mounting after the type of an existing linear Hall element is selected. The mounting convenience is better.

    摘要： Système de sécurité (1000) pour un outil électroportatif (10), comprenant :
    - l'outil électroportatif (10), comprenant :
    - un organe d'usinage (4) et un organe de support (2),
    - un pad (12) en matériau conducteur électrique, arrangé pour entourer au moins partiellement le corps (9) de l'outil (10) et pour être saisi par un premier membre de l'utilisateur,

    - un premier et un deuxième transformateur (T1, T2).
    Un circuit électrique (1) comprenant :
    - un enroulement secondaire (L2) du premier transformateur (T1),
    - un enroulement primaire (L3) du deuxième transformateur (T2),
    - une première borne (D1 ; D2) connectée au pad (12),
    - une deuxième borne (D2 ; D1) connectée à l'organe d'usinage (4) et/ou à l'organe de support (2)
    est arrangé pour être fermé lorsqu'un élément d'impédance raccorde la première borne avec la deuxième, en sorte qu'un courant induit (Id) circule dans le circuit. Un module de commande est arrangé pour générer une alarme et/ou pour modifier la vitesse d'un actionneur, sur la base d'un signal de mesure induit dans l'enroulement secondaire (L4) du deuxième transformateur (T2).
