摘要： A power tool, a saw and a circular saw. The power tool may include a handle including a support portion movably supportable on the housing portion and extending substantially about the circumference of the housing portion. The support portion may include a secon end movable relative to a first end such that the support portion selectively applies a force to the housing portion. The saw may inclu a bevel angle detent mechanism in which one of the detent member and the recess is angularly adjustable relative to the associated one of the detent support and the recess support to adjust the predetermined bevel angle position. A bevel angle detent mechanism may include an engagement operating assembly operable between a detent engagement-enabled condition, in which the detent member is engageable in the recess, and a detent engagement-prevention condition, in which the detent member is prevented from engaging the recess.

摘要： PROBLEM TO BE SOLVED: To provide a cam-driven hammer mechanism for a power tool. SOLUTION: The cam-driven hammer mechanism 14 has a drive mechanism housing 46 connectable to the housing of a power tool, a first cam member 102, a second cam member 104, and a gear assembly 54 for connecting the first and second cam members on a driving basis to a driveshaft 42 so that they can rotate in opposite directions. The first and second cam members each have at least one cam surface 106, 122, which is oriented at a steep angle to the axis of the tool element and is complementary to and engageable with the other cam surface. The second cam member has an impact surface engaging the tool element to give it an impact. When the cam members are rotated in opposite directions, the cam surfaces engage each other and the second cam member is moved in one axial direction relative to the first cam member. As the counterrotating state of the cam members is continued, the cam surfaces disengage from each other and the second cam member is moved in the opposite axial direction relative to the first cam member to thus give an impact to the tool element.

摘要： A cam drive hammer mechanism (14). The drive mechanism includes a drive mechanism housing connectable to the housing (26) of the power tool, a first cam member (102), a second cam member (114) and a gear assembly (54) for drivingly connecting the first cam member and the second cam member to the drive shaft for counter-rotation. The first cam member and the second cam member each have at least one of cam surface (106-122), the cam surfaces being oriented at a steep angle with respect to the axis of the tool element, each of the cam surfaces being complementary and engageable with one another. The second cam member (114) includes an impacting surface for engaging the tool element to provide an impact. As the cam members counter-rotate, the cam surfaces engage so that the second cam member is axially moved in a direction relative to the first cam member. As the cam members continue to counter-rotate, the cam surfaces disengage so that the second cam member is axially moved in an opposite direction relative to the first cam member to provide an impact on the tool element. Preferably, each cam member includes less than five, and, most preferably, two cam surfaces, and the cam surfaces are oriented at between approximately 30 DEG and 60 DEG with respect to the axis of the tool element.
