Abstract: A joint includes a cylinder, a C-clip and a ring. The cylinder includes a thread and a nozzle. The nozzle includes a neck and a head. The head includes a rear face and a front face. The C-clip includes a front end and placed on a first section of an expansible hose. Thus, a second section of the expansible hose is placed between the front end of the C-clip and the rear face of the head. Moreover, a fold between the first and second sections of the expansible hose is stuck between the nozzle and the C-clip. The ring includes a thread and a frusto-conical face. The thread of the ring is engaged with the thread of the cylinder. The frusto-conical face of the ring is located near the frusto-conical external face of the neck to force the C-clip to press the first section of the expansible hose on the neck.

Abstract: An axially expansible pipe assembly includes at least one internal pipe and an external pipe. The internal pipe is axially and radially expansible. The external pipe is only axially expansible. The axially expansible external pipe is used to wrap the internal pipe and confine radial expansion of the axially and radially expansible internal pipe in a predetermined range.

Abstract: A joint includes a cylinder, a C-clip and a ring. The cylinder includes a thread and a nozzle. The nozzle includes a neck and a head. The head includes a rear face and a front face. The C-clip includes a front end and placed on a first section of an expansible host. Thus, a second section of the expansible host is placed between the front end of the C-clip and the rear face of the head. Moreover, a fold between the first and second sections of the expansible host is stuck between the nozzle and the C-clip. The ring includes a thread and a frusto-conical face. The thread of the ring is engaged with the thread of the cylinder. The frusto-conical face of the ring contacts the frusto-conical external face of the neck to force the C-clip to press the first section of the expansible host on the neck.

Abstract: A gardening hose reel includes a main frame, having a reel notch, which is provided for roll-up of the gardening hose. The water inlet terminal of the gardening hose is pulled outward from the central outlet of the reel notch and affixed to the faucets and the water outlet terminal goes through the through notch on the other end of the main frame. The features of the present invention include a rotary connector, which is installed on the water outlet terminal of the gardening hose at the reel notch outlet segment; when the water outlet terminal of the gardening hose is pulled outward, the water inlet terminal turns with the rotary connector to inhibit linkage with the water inlet terminal of the gardening hose so as to prevent the gardening hose from spiral and twisted shape.

Abstract: A hose winder includes a frame, and a hose guiding device which is prefabricated and disposed in a chamber of the frame. The hose guiding device includes a first roller mounted on a first shaft, and a second roller mounted on a second shaft. The first shaft is slidably disposed in a first inclined track. The second shaft is slidably disposed in a second inclined track. The distance between two corresponding points of the two inclined tracks is variable, thereby enabling hoses of various specifications to be reeled out and reeled in between the first roller and the second roller.

Abstract: A water sprinkler includes a main body, a primary nozzle, and an auxiliary nozzle. The main body is provided with a water admitting pipe in communication with the primary nozzle by which a portion of the incoming water is distributed to the areas farther from the sprinkler. The auxiliary nozzle is rotatably mounted on the top end of the main body and is provided with an inclined edge forming adjustably a gap in conjunction with an inclined guide edge of a water chamber of the main body. The rest of the incoming water is guided into the water chamber from which the water is distributed via the gap to the areas closer to the sprinkler.

Abstract: A pistol nozzle is constructed to include a body, a cap covered on the body, a spray-pattern disc and a spray-pattern dial fastened together and coupled to the cap, and a control ring for rotating the spray-pattern disc and the spray-pattern dial to control the spray pattern of water, the spray-pattern dial having a smoothly arched water hole disposed in communication with one water outlet of the spray-pattern disc for output of water from the body to produce a wide spray pattern of water.

Abstract: A pistol nozzle of lawn sprinkler including a handle, a barrel, and a water control device. The handle is provided with a water admitting channel, whereas the barrel is provided with a water discharging channel. The water control device is disposed at the juncture of the water admitting channel and the water discharging channel. The water control device includes a valve rod which is provided with a piston to control the discharge of water by the barrel.

Abstract: A water pipe joint includes a main body, a control sleeve, and an elastic element. The main body is provided with a plurality of expansion holes and receiving slots. The elastic element is disposed in a receiving gap of the main body. The control sleeve is provided with a plurality of retaining blocks and resilient pieces. The control sleeve is joined with the main body such that the retaining blocks of the control sleeve are slidably received in the receiving slots of the main body, and such that the retaining blocks of the control sleeve are acted on by the elastic element and the resilient piece to extend out of the expansion holes of the main body, so as to be detachably engaged with a water discharging connector.
