A quick-release screwdriver structure includes a tool holder and a tool head embedded in a head portion of the tool holder. A fixing seat is sleeved outside the tool head; an inner wall of the fixing seat is provided with a notch, and a bottom surface of the notch is an inclined surface; a steel ball connected to a release ring is installed in the notch, and the steel ball contacts the tool head; and a movement of the release ring will drive the steel ball to move along a longitudinal direction of the bottom surface of the notch so as to lock or release the tool head. A new locking assembly is designed to act on a surface of the tool head so as to achieve locking and disassembly of the tool head.

A wrench extension apparatus is an apparatus that serves to extend the moment arm of a wrench to increase the leverage on a mechanical fastener, so that the mechanical fastener is fastened or loosened easily without much effort from the user. The apparatus may include a breaker bar, at least one proximal protrusion, and at least one distal protrusion. The breaker bar increases the moment arm of a wrench to increase the torque being applied to the mechanical fastener. The breaker bar is also designed to be comfortably gripped without hurting the user's hand. The at least one proximal protrusion and the at least one distal protrusion enable the breaker bar to be engaged with the desired wrench. Further, the at least one proximal protrusion and the at least one distal protrusion enable the breaker bar to be used with wrenches of different sizes without the need to switch wrenches.

A pool cleaning system is provided. The system includes a pool pole. The system also includes an angled attachment device configured to connect to an end of the pool pole. The system additionally includes specialty tools structured to connect to an end of the angled attachment device. The angled attachment device is structured to connect to pool poles and to specialty devices in such a way to provide a plurality of angles to allow cleaning of pool surfaces and pool surface areas in an effective, efficient, and ergonomically friendly fashion for pool cleaning personnel. The pool cleaning system is arranged to change the angles at which the surfaces are being cleaned without having to change out components.

A mop tool is provided. The mop tool includes: an elongated stick; a cleaning head which includes a head body that has a coupling portion rotatably coupled to one end of the stick, and a gap portion that extends from the coupling portion of the head body toward at least one side of the head body; and a rotation control element which is installed on the stick so as to be movable along the stick. The rotation control element includes a locking member which is releasably coupled to at least a part of the head body which adjoins the gap portion, and restricts a relative rotation between the cleaning head and the stick.
