The invention discloses a multifunctional quick assembly mounting hole for swing tools, comprising an assembly bottom plate, a bending transition segment, and a tool head connecting plate, wherein the bending transition segment is arranged between the assembly bottom plate and the tool head connecting plate; the bending transition segment is arranged obliquely, and the bending transition segment is in arc transition between the assembly bottom plate and the tool head connecting plate; the assembly bottom plate is provided with a first assembly positioning boss and a second quick assembly positioning boss. The invention relates to the technical field of electric tools, in particular to a multifunctional quick assembly mounting hole for swing tools with high practicability, simple structure, convenient carrying, quick assembly, wide application range, which is suitable for multiple machine connection modes.

The present embodiment discloses a hand-held tool and a clamping device thereof. The clamping device of a hand-held tool includes: a mounting base; a clamping unit configured to fasten a working tool in an axial direction; and an operation assembly, including an operating member and a driving member, where the operating member is capable of performing compound motion relative to the mounting base, and the operating member is operable to drive the driving member to selectively mate with and disengage from the clamping unit. In this way, the hand-held tool of the present embodiment has the clamping device. By way of compound motion, not only comfort of operation can be achieved, but also parts can be saved, thereby making the structure simpler and more reliable.

The present disclosure relates to a saw, comprising a drive, a first blade configured to oscillate about an axis perpendicular to a plane defined by a surface of the first blade, a second blade configured to oscillate about an axis perpendicular to the plane in a direction opposite to that of the first blade, and wherein gearing is provided between the drive and the first and second blades to reduce the speed transmitted from the drive to the blades. A saw blade, a connection mechanism for connecting a blade to a saw and associated methods are also provided.

Apparatus comprising: a rotatable drive shaft (12): one or more members (16a-d) mounted for oscillators, pivoting motion: motion conversion means (17, 28a-d, 16a-d) for convening rotational motion of the drive shaft to the oscillatory, pivoting motion of the one or more members: means coupling the or each member and one or more saw blades (14a-f) so that the oscillatory motion of the one or more member causes oscillatory cutting action of the or each blade. There is also provided a saw blade, and a method of attaching a saw blade.

A power tool system includes a portable power tool having a housing, a motor with an output shaft in the housing, a tool holder secured on the output, and a data reader. The system also includes a power tool accessory configured to be retained by the tool holder that has a data storage device having data stored thereon. The data reader is configured to access the data stored on the data storage device when the power tool accessory is retained by the tool holder.

An oscillating blade for cutting or shaping sheet materials such as drywall, with a blade, a sharing portion, a depth gauge for determining depth of cut, a caliper portion for premarking sheet materials for a standard dimension cut, and a reverse direction blade.

An accessory for an oscillating power tool includes an attachment portion configured to be coupled to an oscillating power tool and a working portion coupled to the attachment portion and extending generally along a longitudinal axis. The working portion has a generally planar wedge shape bounded at least partially by a rear non-cutting end with a first width, a front cutting edge opposite the rear edge with a second width that is greater than the first width, a first side cutting edge extending from a first end of the rear end to a first end of the front cutting edge at a first angle to the longitudinal axis, and a second side cutting edge opposite the first side cutting edge and extending from a second end of the rear end to a second end of the front cutting edge at a second angle to the longitudinal axis.

A power tool attachment saw according to the invention is provide and includes a body plate, a connector section and a plurality of cutting walls. The body plate is a planar body and the connector section positioned on one side of the planar body and adapted for attachment to an oscillating power tool. The plurality of cutting walls are positioned orthogonal to and extend from exterior edges of the planar body to form a material receiving space. The plurality of cutting walls provide a uniform cutting edge about the material receiving space.

A cutting assembly for cutting with at least two saw blades simultaneously, includes a motion conversion means comprises: a first part and a plurality of second parts, for example a first bevel gear (30) and a plurality of second bevel gears (32). The first part is arranged for rotation about a central axis thereof and coupled to a drive means (12) for causing the rotation. The first and second parts are arranged such that the rotation of the first part in a direction of rotation causes rotation in a corresponding direction of rotation of each second part about a respective axis extending away from the central axis of the first part. The cutting assembly also includes, for each second part, a coupling means for coupling the second part to a respective cutting blade (100a-f) and including a further motion conversion means, such that the rotation of the second part causes cutting motion of the cutting blade.
