    摘要: An electric hammer comprising a hammer bit performing hammering work on a work, a drive motor, a hammering piece driven by the drive motor to apply a hammering force to the hammer bit, and a mechanism for damping vibration generated during hammering. The damping performance of the electric hammer is enhanced by causing the driving amount applied to the damping mechanism to vary between a first mode where the damping mechanism generates vibration of the hammer bit subjected to an external force from the work during the load driving time and thereby optimizes the damping and a second mode where the damping mechanism generates vibration corresponding to the vibration of the hammer bit not subjected to an external force from the work during the no-land driving time and optimizes damping.

    摘要: A powered hammer is described comprising a housing, a tool holder mounted on the housing, a percussion mechanism arranged within the housing which mechanism includes a ram reciprocating in a longitudinal direction and being adapted to apply impacts on a tool bit supported in the tool holder, a dampening mass which is slidably mounted in the longitudinal direction within the housing, wherein the dampening mass is biased towards a neutral position by a biasing element and wherein the dampening mass may be deflected from the neutral position against the biasing force of the biasing element. The dampening mass is formed of a ferromagnetic or paramagnetic material or comprises a permanent magnet and a solenoid is arranged within housing adjacent to the dampening mass such that the solenoid applies a force in the longitudinal direction on the dampening mass when being in the neutral position if a current is flowing through the solenoid.

    摘要: An impact tool for simultaneously providing a rotational force and an impact force to an object has an output shaft rotated by a motor, hammer for intermittently providing an impact force to the output shaft, hammer holder for movably holding the hammer, and an impact force generator for generating the impact force from an output of the motor. An air chamber is formed between the hammer and the hammer holder such that a volume of the air chamber is variable in response to a position of the hammer relative to the hammer holder. In addition, the hammer receives a bias force generated in a direction toward the output shaft by a biasing device. This bias force effectively increases the impact force in cooperation with an air pressure caused by a volume change of the air chamber.

    摘要: To reduce size increase, a power tool includes a motor, an output shaft located frontward from the motor, rotatable by the motor, and having an insertion hole extending rearward from a front end of the output shaft, a bearing supporting the output shaft in a rotatable manner, a locking member supported by the output shaft and movable to a locking position for locking a tip tool placed in the insertion hole and to an unlocking position for unlocking the tip tool, a bit sleeve surrounding the output shaft, and movable to a movement-restricting position for restricting radially outward movement of the locking member and to a movement-permitting position for permitting radially outward movement of the locking member, and an operable member operable to move the bit sleeve and at least partly overlapping the bearing in an axial direction.

    摘要: A universal center punch has a body with a passage therein, a punch rod extending along the passage, a first leg pivotally mounted adjacent one side of the body so as to extend outwardly of the body, and a second leg pivotally mounted adjacent an opposite side of the body so as to extend outwardly of the body. The first and second legs are linked together so such that a movement of one of the legs causes a corresponding movement of the other leg. Each of the legs has a magnet thereon. An inclinometer can be removably affixed to the body so as to measure an inclination of the punch rod.
