POWER TOOL

摘要

A power tool which has an anvil 20 that is rotated by a hammer 22 and is housed in a housing, and rotates an output shaft 18 is provided. The anvil 20 and the output shaft 18 are integrally formed into one unit, and a carrier 33 that is rotatable relative to the anvil 20 by a predetermined angle on the same axis is provided. On one portion of an outer circumferential surface of the anvil 20, a relief surface 20a is formed. Cut-out portions 33b are formed at positions opposed to each other of a carrier 33, and by allowing an engaging pin 37 to be interposed therein, a locking mechanism that limits the relative rotation between the anvil 20 and a lock ring 38 is prepared. When the tool main body is manually rotated while the hammer 22 is being stopped, the engaging pin 37 limits the relative rotation between the anvil 20 and the lock ring 38. The locked state between the anvil 20 and the lock ring 38 is released immediately when the rotation of the motor 4 is started.

1. A power tool comprising: a housing that houses a driving source;
a hammer that is driven in a rotation direction by the driving source; an anvil that is driven in the rotation direction when being engaged with the hammer; and a locking mechanism that switches modes as to whether or not to lock the rotation of the anvil relative to the housing, wherein a lock releasing member is rotatably provided to the anvil, and when the hammer is rotated, prior to the engagement of the hammer with the anvil, the hammer is engaged with the lock releasing member so as to release the locked state of the locking mechanism, and with the hammer being engaged with the anvil, the lock releasing member is rotatable between the hammer and the anvil.
