A tool assembly includes a handle and a connection end which is connected to the handle by way of blow molding or ultra-sonic fusion. The connection end can be made by plastic injection molding. The handle can be made by way of blow molding. The connection end has a slot defined axially therein. A blade includes a body and a toothed portion. The toothed portion of the blade is connected to the slot of the connection end. The toothed portion is inserted into the slot of the connection end when the connection end is molded by way of blow molding so that the toothed portion of the blade is connected to the slot of the connection end. The toothed portion has multiple teeth and each tooth includes an inclined edge tapered toward the downward toward the connection end.

A reconfigurable modular brush has a brush head including brush-head upper and lower surfaces extending longitudinally along a brush-head axis between brush-head first and second ends. Laterally opposed brush-head first and second sides extend between the brush-head upper and lower surfaces and longitudinally between the brush-head first and second ends. A bristle array is defined by a plurality of bristles protruding from the brush-head lower surface. A brush handle includes a grip portion and a brush-head mount, the brush handle having a lengthwise extent disposed generally along a handle axis between handle proximate and distal ends. The brush head and brush-head mount are cooperatively configured such that the handle can selectively capture and retain the brush head. Moreover, the longitudinal orientation in which the brush head is captured and retained by the brush handle is selectively reversible.

A versatile flexible cleaning apparatus including a removable and reusable pad and a core having a central spine. The pad has an opening for insertion or removal of the core. A spacer provides support for the central spine. A connector is a two-part device attachable to a tool, such as the flexible cleaning apparatus, for the addition of a selected handle. A swivel having a locking feature is also attached to the connector. The connector allows for the tool to be quickly and easily converted from a handheld dusting apparatus to a floor mop.

A combination screwdriver tool includes a tool connector, a main unit connected with the tool connector, and a rear cover connected with the main unit. The main unit includes multiple connecting sections located between the tool connector and the rear cover. The connecting sections and the rear cover receive a plurality of screwdriver tips. Thus, the combination screwdriver tool stores and provides multiple screwdriver tips of different shapes, sizes, and specifications. In addition, the number of the connecting sections is adjusted freely.

Provided is a connection structure of an operation rod in which a connection object such as a tip tool can be easily attached to and detached from the operation rod in a relatively short time without causing a fixed state. The main body is inserted into the cylindrical operation rod on the tip side. An engagement pair is formed of an engagement part with a notch provided to the main body on a tip side and an engagement part with an engagement pin provided to a tip tool. An inner slider on which a recessed groove is formed in a circumferential direction is relatively slidably disposed to the main body on an inner diameter side. An outer slider is relatively slidably disposed to the main body on an outer diameter side, wherein an opposing recess which can oppose to the recessed grove is formed on the outer slider.

A hand tool includes a handle which is a hollow handle with a space defined therein. A connection portion has a slit defined in the first end thereof. The connection portion has two ribs extending inward from an inside of the second end thereof. The handle has a tubular portion extending from one end thereof. A protrusion extends outward from outside of the tubular portion. The tubular portion is inserted into the second end of the connection portion, and the ribs are engaged with the protrusion. A blade has a body and a toothed portion. The toothed portion is inserted into the slit of the connection portion. A cooling material is located in the space of the handle. The connection portion of the handle is connected to the toothed portion of the blade. The cooling material performs as a weight in the handle.
