摘要:
Die Erfindung betrifft eine Schere, vorzugsweise elektrische Schere (1), mit einem feststehenden Messer (101) und einem um eine Drehachse (7) schwenkbar gelagerten beweglichen Messer (102), mit einem, vorzugsweise elektrischen, Antrieb (104), welcher eine Anlenkeinrichtung (105) antreibt, und wobei die Anlenkeinrichtung (105) mit dem beweglichen Messer (102) verbunden ist, wobei das bewegliche Messer (102) zumindest zwei Anlenkpunkte (201, 202) für eine gelenkige Verbindung mit der Anlenkeinrichtung (105) aufweist, und wobei die Anlenkeinrichtung (105) je nach Anlenkpunkt (201, 202), an welchem sie angreift, unterschiedliche Hebellängen (L1, L2) in Bezug auf die Drehachse (7) des beweglichen Messers (102) aufweist, und wobei die Anlenkeinrichtung (105) zwischen den beiden Anlenkpunkten (201, 202) umschaltbar ist.
摘要:
The invention relates to a hand-held motor-driven cutting tool. The tool comprises: a support (1) in which first and second jaws (2, 3) are mounted, one (2) of said jaws being pivotable about an axle (5) of the support body (1); actuation means (4) which are mechanically connected to the pivoting jaw (2); a trigger which is designed to activate the actuation means (4) in order to move the pivoting jaw (2); and first position detecting means comprising a detector (D1)able to continuously detect the positions adopted by the pivoting jaw (2). The invention also comprises second position detecting means which comprise a detector able to continuously detect the positions adopted by the trigger and an electronic system which establishes a univocal correspondence between each of the positions detected for the trigger and a corresponding position detected for the pivoting jaw (2).
摘要:
A device for mechanized pruning and the like, comprising a cutting unit (1) having a first blade (2) and a second blade (4) in rotation therebetween, suitably for continually carrying out successive cutting cycles; actuation means for actuating said cutting unit, comprising a motor (200); a feeler (7), hinged at said blades (2,4) so as to assume a position median to the space between said first and second blade (2,4), said feeler (7) being suitable for intercepting a body (80) to be cut off; and a lever (8), integral to said feeler (7) and hinged thereat, suitable for obtaining a consent to the starting of said motor (200); wherein said feeler (7), by intercepting said body (80) to be cut off, undergoes a displacement that induces a corresponding displacement of said lever (8), so that said lever contacts a first switch (50) of a circuit for powering said motor (200) determining its closing.
摘要:
The device is associated to a tool comprising a support (1), a motor, a cutting mouth (4) with at least a moving jaw (5) driven by that motor for carrying out a closing-opening motion with respect to the other jaw (6) and a handle (8) with an activation push button (9) for the motor for driving such motion and a safety control (10). Such device comprises a detector (12) provided with a field of action capable of detecting the presence of an object in the area of the cutting mouth (4) between the said two jaws (5, 6). When an object is detected by the detector (12), the later releases a signal which enables the motor to automatically carrying out the said closing-opening motion of the jaws (5, 6).
摘要:
A power tool comprises an elongate housing comprising a battery. The elongate housing has a first end and a second end. The first end has a first electrical interface for removably receiving a first tool accessory comprising a first electrical component capable of being powered by the battery. The second end has a second electrical interface for removably receiving a second tool accessory comprising a second electrical component capable of being powered by the battery.
摘要:
A foreign matter detecting mechanism of electric scissors detects pinching of a foreign matter in the electric scissors. The electric scissors have blade sections which are interlocked with a rotation of a motor. The mechanism includes a foreign matter detecting unit. The foreign matter detecting unit detects that the blade sections pinch the foreign matter. The foreign matter detecting unit detects the foreign matter based on torque information of the motor.
摘要:
A cutting tool has a cutting head, a motor and a transmission means drivable by the motor. The cutting head comprises first and second cutting members, wherein the first cutting member is pivotably moveable with respect to the second cutting member. At least the first cutting member is drivable by the transmission means between a first angular position with respect to the second cutting member and a second angular position with respect to the second cutting member, in which a space between the respective cutting blades is closed. The transmission means is a bevel gear on the output shaft of a gearbox which conveys drive power from the motor to the drive gear. The bevel gear directly engages a bevel wheel member connected to the first cutting member and which swivels with the first cutting member about the same swivel point. A controller comprises main, first and second switches which control the motor to move the first cutting member (movable blade). The main switch acts as a main power switch whereas the first ad second switches act as limit switches detecting movement of said movable blade at the limits of its intended motion. The controller exerts automatic control over movement of the first cutting member in response to inputs from the first and second limit switches.
