An adapter is arranged to secure to a rotary device. The adapter includes a handle rotatable about an axis, and a coupler extending from and coaxial with the handle. The coupler is adapted to engage the rotary device via traction elements for simultaneously rotating the rotary device and the handle.

A handle configured to be attached to a pumice stone. The handle includes a gripping portion and a post extending from the gripping portion. The post is configured to support the pumice stone. The post includes a support member, a series of ribs spaced apart along a length of the support member, and a series of cavities defined between adjacent ribs. The cavities are configured to accommodate an adhesive for coupling the post of the handle to the pumice stone.

A cleaning tool for use in abrading a surface for cleaning the surface includes a resiliently deformable backing member insert, and a chain mail abrader enclosure comprising a chain mail body having a plurality of interlinked rings. The chain mail abrader enclosure is configured to allow for insertion and removal of the resiliently deformable backing member insert. The resiliently deformable backing member is disposable within the chain mail abrader enclosure such that the backing member is positioned against the chain mail body to allow the chain mail body to conform to contours of the surface during abrading.

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.

Provided is a tool that includes a handle assembly including a top portion and a bottom portion. The tool also includes a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, an inner edge, an outer edge, and a detent near the free end and the inner edge. The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

A drain cleaning apparatus includes a handle and a clog-catching member detachably connected to the handle. Wings, barbs or hooks project radially from the clog-catching member. The wings, barbs or hooks provide an angled projection that catches and holds a clump of debris in a drain pipe for pulling the clump out and unclogging the drain. Different end tools can be removably connected to a clog-catching member or to a smooth extension member to provide multifunctionality. The handle, clog-catching members, smooth extension members and tools can be connected together using a quick-connect connector, such as a snap fastener, a keyhole fastener or a side-release buckle, or a threaded connector. In addition to drain cleaning, the apparatus can be fitted with tools such as a magnet, grabber, light, camera and/or video for retrieval of objects and inspection of a space that is difficult to view directly.

The present invention provides a hand tool with reliable connections comprising: a working unit having a working end and a handle end opposite to the working end; a handle being mounted on the handle end of the working unit and having a working unit end and a knocking unit end; a knocking unit being mounted on the knocking unit end of the handle. The connecting part between the knocking unit and the handle end of the working unit is a contacting surface, the handle end or the contacting surface is configured as a deformable and non-rigid contact, realizing the reliable connection between the working unit and the knocking unit. The deformable and non-rigid contact is realized by the configuration of at least one of the contacting surface and the handle end being configured to be tooth-shaped, the tooth-shape can deform and form a gapless engagement with the contacting surface. This configuration lowers the precision requirements for the production of each part; saves the costs; achieves reliable connections among the working unit, knocking unit and the handle of the hand tool; and disperses the impact force that damages the handle.

A toothbrush with a front-push replaceable brush head includes a handle portion, a handle front section connected to the handle portion and having a supporting platform, a front-push mechanism including a pulling arm pivotally attached to the handle portion and push and locking plates stacked together penetrating the handle front section, the pulling arm driving the push and locking plates to move; a brush head replaceably installed on the supporting platform, the locking plate locked onto the brush head and handle front section; the pulling arm is pulled and rotated to move the locking and push plates toward the brush head and to release the locking plate, handle front section and brush head from locking while the push plate pushing the brush head away from the supporting platform. Therefore, the release of locking and disengagement of the brush head are achieved simultaneously to facilitate operations of the toothbrush.
