摘要： An arrangement for a power tool, the arrangement comprising a base structure; a drive member rotatable from a neutral position; a stopping device comprising a movable element and a limiting element; wherein the stopping device is arranged to adopt a first state where the stopping device allows rotation of the drive member in a first direction and generates a first counter torque; wherein the stopping device is arranged to adopt a second state where the stopping device allows rotation of the drive member in a second direction and provides a second counter torque; and wherein the stopping device is deflectable to switch from the first state to the second state by rotating the drive member in the second direction from the neutral position with a second switching torque overcoming the first counter torque.

摘要： A transducer for measuring the characteristics of a clamping instrument includes a stator which has an annular support adapted to form a substantially cylindrical longitudinal cavity adapted to receive a rotor which is also substantially shaped cylindrical adapted to rotate inside this cavity of the stator around its longitudinal axis, this rotor being provided at one end with a seat for insertion into it of the head of an instrument of tightening which determines such rotation around the axis, and a sensor arranged on its body capable of detecting specific parameters of the tightening of the instrument, and generating corresponding electrical signals. The transducer includes a magnetic coupling device adapted to transfer electrical energy from the stator to the rotor and an optical coupling device adapted to transfer the electrical signals generated by said sensor means from the rotor to the stator.

摘要： The present specification relates to a two-speed power transmission for a power tool comprising a planetary gear and a torque responsive gear shift mechanism for directing torque through the planetary gear in a high torque/low speed mode or past the planetary gear in a low torque/high speed mode, and comprising a driving member, a driven member, and a number of coupling elements arranged to intercouple in a first position the driving member and the driven member and in a second position the planetary gear and the driven member, the driving member comprising a number of recesses and axially acting first cam means for cooperation with the coupling elements in the first position forming part thereof. The present specification also relates to power tool comprising such a gear unit and a method for controlling such a power tool.

摘要： A method and a device for detecting the oil level in a hydraulic pulse unit at an impulse type power wrench, wherein the pulse unit comprises an oil filled pulse chamber, a motor driven inertia drive member, and a kinetic energy receiving member connected to an output shaft and intermittently coupled to the inertia drive member via an oil cushion to receive kinetic energy from the inertia drive member during repeated energy transfer phases. The rotation speed of the inertia drive member is measured both at the start of a pulse generating phase and at the end of that phase, wherein the two measured speeds are compared to each other, and when the speed at the end of the pulse generating phase exceeds the speed at the end of that phase by a certain percentage a faulty signal is emitted indicating a too low oil level in the pulse unit.

摘要： Provided is a cylinder connection assembly comprising a ventilation connection sleeve sleeved on a piston shaft of the cylinder, the ventilation connection sleeve fixedly provided in a cylinder barrel of the cylinder and separates an inner cavity of the cylinder barrel to form front and rear air chambers, a first ventilation hole communicating with the front air chamber and a second ventilation hole communicating with the rear air chamber are provided on the ventilation connection sleeve, so that when the compressed gas is filled into the front air chamber through the first ventilation hole, or the compressed gas is filled into the rear air chamber through the second ventilation hole, the piston assembly in the cylinder barrel can move axially. Through the ventilation connection sleeve provided in the cylinder barrel, the compressed gas can directly enter the front air chamber or the rear air chamber through the ventilation hole thereon.

摘要： A screw forwarding device for a screw feeder includes a base plate, a vibration mechanism including at least one spring and a vibration motor connected to the at least one spring, and a rail for receiving screws. The rail is connected to a first end of the at least one spring and the at least one spring is arranged at an oblique angle to the rail. The screw forwarding device further includes a fastening mechanism for rigidly connecting a second end of the at least one spring to the base plate, whereby a movement path of the vibration mechanism, during a use of the screw forwarding device, defines a plane of movement. The base plate is oriented substantially parallel to the plane of movement defined by the vibration mechanism.
