摘要： A power tool including a sliding member slidably received in the power tool and a pair of lock plates, each of the pair of lock plates including an opening, and the lock plates being configured such that the sliding member slides within the opening. First ends of each of the lock plates are pivotably attached to a support at a first side of the sliding member, and second ends of each of the lock plates being biased toward one another at an opposite side of the sliding member. A first contact portion of the lock plate contacts a first surface of the sliding member at the first side of the sliding member, and a second contact portion of the lock plate contacts a second surface of the sliding member at the opposite side of the sliding member, wherein the sliding member is secured with respect to the support.

摘要： The present invention relates to a reciprocating saw tool (10) having a motor drive (17) with a reciprocating driver (21) for a tool (15) and having a mass equilibrating body (22). In addition, a device (20) is provided, which serves to convert a rotary movement of the motor drive (17) into a reciprocating movement of the reciprocating driver (21) along a first movement axis (41) and an opposite reciprocating movement of the mass equilibrating body (22) along a second movement axis (42). For improving the sawing performance, the mass equilibrating body (22) is guided at an angle α to the reciprocating driver (21) so that its movement axis (42) is constantly at an angle to the movement axis (41) of the reciprocating driver (21).

摘要： A hand-held saw with a rigid saw frame is disclosed. The rigid frame of the hand-held saw allows a saw blade to remain highly tensioned during the cutting process. The rigid saw frame has a “C-shape,” is unbent, and contains openings that make up a truss-like structure, which distributes an external force that is focused on one portion of the saw frame across other portions of the saw frame.
