A hand power tool includes a tool receiver configured to receive a tool. The tool has an outer polygonal coupling and the tool receiver has an inner receiver including, at least portionally, a rotary driver profile. The tool receiver is provided on an associated tool housing, in which there is a drum-type tool change magazine having at least one tool chamber configured to store the tool. The tool chamber is configured to be aligned so as to be flush with the tool receiver to enable the tool to slide from the tool chamber into the inner receiver or from the inner receiver into the tool chamber. An alignment element is configured to align the outer polygonal coupling as the tool slides from the tool chamber into the inner receiver to enable the outer polygonal coupling to slide into the rotary driver profile.

A dust collector for use with a power tool comprises a housing, a telescoping suction pipe coupled to the housing, a suction fan positioned in the housing and operable to generate a vacuum in the suction pipe, a dust container coupled to the housing and positioned upstream of the fan, a filter at least partially arranged in the dust container, and a filter cleaning mechanism. The filter cleaning mechanism includes an anvil, a striker moveable between a first striker position, in which the striker is spaced from the anvil, and a second striker position, in which the striker is in contact with the anvil. The filter cleaning mechanism further includes an actuator moveable between a first actuator position and a second actuator position, in which the actuator is moved closer to the anvil than in the first position, and a first spring biasing the striker toward the anvil.

An installation tool for fastening a top plate to a roof support member and other structural connections is adapted to drive threaded fasteners at a pre-established angle. The tool preferably includes a rotary driver assembly and a telescopic tube assembly. A guide head assembly is mounted adjacent the outer end of the telescopic tube assembly. Locating or reference structures function to properly precisely set the drive angle of the fastener. Various indicators mounted to the guide head indicate the flush position of a locating surface or reference structure. The flush indicators may employ a projection, a flag, an LED or an audio module.

A tip tool holder includes a nail portion to be inserted in an attachment hole formed in a power tool, an accommodation portion capable of accommodating a tip tool, and an opening opposite to the nail portion. The accommodation portion accommodates the tip tool such that an axis of the tip tool is substantially perpendicular to a direction in which the nail portion and the opening face each other. The tip tool holder includes a first arm and a second arm opposite to each other. The opening is included in the first arm while the nail portion is provided to the second arm.

A component for a bit driving tool is taught having a mid-chamber telescopically received in an outer chamber, a bit storage chamber formed in the mid-chamber and surrounding and rotatable about a central bore, a central rod axially movable through the central bore when the mid-chamber is telescopically retracted into the outer chamber and a flexible arm comprising a magnetic end, movable into and out of axial alignment with the central bore. Telescopic extension of the mid-chamber out of the outer chamber positions the magnetic end of the flexible arm to magnetically connect with a rear end of a bit stored in the bit storage chamber and telescopic retraction of the component moves the flexible arm and the magnetically connected bit radially into the central bore and wherein further telescope retraction of the component pushes the bit axially through and out of the component. A locking tip for use with a bit driving unit is also taught.

A smart power hub having a number of electrical connections for power electric power tools. The smart power hub comprises a controller, a processor, and a number of sensors operable to measure operational behavior of the electrical connections or connected electric power tools. The processor may utilize data from the sensors to generate control commands for the controller to control the current output of the number of electrical connections. Additional functions of the processor may provide smart feature operation to connected tools.

A power tool includes a housing, a motor disposed in the housing, an output spindle extending outward from the housing and configured to be rotationally driven by the motor, a keyed chuck coupled to the output spindle for rotation with the output spindle, and a chuck key holder configured to releasably retain a chuck key with a first shaft with a key disposed thereon for operating the chuck, and a second shaft coupled to the first end portion of the first shaft generally perpendicular to the first shaft, the second shaft including a lever portion. The chuck key holder includes a first recess configured to receive the first shaft and a second recess with a sheath configured to receive the second shaft with the lever portion exposed from the sheath.

An electrical equipment system includes electrical equipment, a battery pack with a wireless communication function which is mounted to the electrical equipment, and a portable terminal wirelessly communicable with the battery pack. The electrical equipment includes a drive part, a control part which controls the drive part, an operation part which instructs start and stop of the drive part, and a storage part which stores operation parameters for driving the drive part. Various operation parameters, such as an operation amount of the operation part for starting the drive part of the electrical equipment, are configured to be changeable by a management application installed in the portable terminal.

A rotary tool assembly including a rotary tool having a body with a working end and a rear end, a motor disposed within the body, and a drive shaft rotatably driven by the motor. A base includes a battery receptacle configured to receive a battery pack. A power cord extends between the base and the rotary tool to transfer electric power from the base to the rotary tool to selectively power the motor.

A wallet includes a first metal shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; a second metal shell coupled to the first shell with a storage compartment therebetween; and securing a soft material to the first and second metal shells, wherein the soft material comprises compartment to store cards or money therein.
