A quick release mechanism includes a male member including a locking pin, a female member including a cavity for receiving the male member, a locking joint on the female member including a longitudinal bore for receiving the male member, a longitudinal slit for receiving the locking pin, and a locking recess for capturing the locking pin, a spring within the cavity for securing the locking pin within the locking recess, and a bearing enabling rotation of the male member within the cavity. The male member engages the female member by guiding the locking pin into the slit and compressing the spring until the locking pin is released from the slit into the cavity. The locking pin is then able to shift into the locking recess by rotating the male member. The spring exerts a force onto the male member to maintain the locking pin within the locking recess.

A safety hammer is provided that may be designed to prevent injuries caused by flying nails when users accidentally fail to strike nails on their heads. The present invention may provide for a wooden handle with finger grooves. The wooden handle may be reinforced with a steel rod to add strength and attach the handle to the tempered steel head. Close to the end used for striking nails, the present invention may provide for a pin configured to attach the metal shield to the end used for striking nails. The track in the shield may fit over the pin to ensure the pin is positioned correctly around the face of the present invention's hammer face. In some embodiments, the shield may be secured by magnets, which may be embedded around the present invention's hammer head. The present invention may also provide for a fulcrum point that may be oriented above the nail removal portion of the present invention.

A temporary or permanent attachment device to a broom, mop, or other such cleaning device, or other stick/rod, which needs to be propped upright temporarily when not in use or permanently during storage. The attachment provides the ability for the stick to stand freely, independent of leaning against a wall, furniture, door or other to prevent the stick from falling to the ground or against other objects, or people or pets or anything else on its way down. The attachment collapses against the stick. It is basically a case, springs, tines and release levers which are releasably attached to the extended handle of the tool.

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.

A hand tool with a replaceable workpiece head includes a handle and a workpiece head. A rear end of the workpiece head is provided with an insertion block. A front end surface of the handle is provided with an insertion hole. The insertion block of the workpiece head is inserted into the insertion hole. A side wall of the handle is provided with a receiving slot which is communicated with the insertion hole. A rear end of the insertion block is provided with a locking part. The receiving slot is provided with a movable locking member and a pushing mechanism. The pushing mechanism is capable of pushing the movable locking member such that the movable locking member and the locking part are engaged with each other.

The disclosed cleaning tool comprises a handle, a cleaning head, a valve, and a locking mechanism. The handle comprises a fluid chamber and a discharge aperture, and the handle has a working end and a holding end. The cleaning head is secured to the working end of the handle and adjacent the discharge aperture. The valve separates the fluid chamber from a discharge aperture and is actuatable between a first open position and a second closed position. In the first open position the fluid chamber is in fluid communication with the discharge aperture. The locking mechanism locks the valve in the open position or the closed position.
