Abstract: An anti-squirt ring acts as a handle guard for a palm operated garden hose nozzle lever. The guard is a circular ring, which obliquely surrounds the trigger lever of the garden hose nozzle. If the garden hose nozzle is accidentally dropped, the annular guard ring. The guard provides clearance if the trigger lever and nozzle are dropped. Therefore, the trigger lever will not forcefully contact the ground and be accidentally engaged, suddenly and erratically. The guard prevents unwanted spraying water from the nozzle in unwanted directions, such as at the user or at objects which should not get wet. The wire is configured in an annular ring and is either manufactured with the garden hose nozzle, or is attached by clamps, cable ties or hook and loop type fasteners.

The two dividing holes respectively communicate with the central outlet section and the circumferential outlet section. A water generator is disposed between one dividing hole and the central outlet section. When a user turns the cap body, the water dividing disc is driven, whereby the flowing path of the water can be changed to discharge the water in different patterns.

Abstract: A hand-held tool for a diver has a hollow tube to vent pressurized gas from an interconnected source through an opening in the tube. The vented pressurized gas aerates material of a seabed, and an anchoring system disposed adjacent to the tube is effortlessly inserted in the aerated material by a single diver. The hand-held tool permits an improved method of inserting the anchoring system as compared to the time consuming, strenuous, and noisy hammering procedure that usually requires more than one diver to successfully embed an anchor in the seabed. Different sources of pressurized gas for aerating the material may include a portable gas cylinder, diver's air tank, or hose from a remote source, such as a compressor. Quick-change connectors can be used to quickly and easily connect and disconnect components to supply more gas or add different components that will help insert different anchoring systems.
