Abstract: An angle adjustable pistol-type watering nozzle includes a handle, a nozzle head, a control member and a valve. The nozzle head is pivotable relative to the handle by two respective pivotal portions of the nozzle head and the handle. The valve is located in the pivotal portions and is driven by the control member to align the inlet or the seal member of the valve with the passage of the handle to control the watering feature of the watering nozzle. The watering nozzle is functioned normally to eject water from the nozzle head at any angle that the nozzle head is pivoted relative to the handle.

Abstract: An oscillating sprinkler includes a hollow tube having a groove defined axially therein so as to receive a nozzle unit therein. The nozzle unit has flexible nozzles which extend through holes in the inner bottom of the groove. The hollow tube has first paths and second paths defined radially in the outside thereof. The distance between any two adjacent first paths is smaller than the distance between any two of the adjacent second paths. A resilient wire is formed with continuous S-shaped portions, and each S-shaped portion has two adjustment slots opening toward opposite directions. The nozzles are movable in the adjustment slots. The hollow tube is received between a top member and a bottom member. The resilient wire is moved with the movement of the top member. The nozzles are pulled and pushed by the S-shaped portions to have different patterns of sprinkling.

Abstract: A sprinkler includes a base, a positioning collar connected to the base, a gear box connected to the positioning collar and a sprinkling member which is co-rotated with the gear box, and a bypass tube connected between the positioning collar and the sprinkling member. The positioning collar is connected with a hose for introducing water to drive the gear box and the sprinkling member. A portion of the water from the hose enters the bypass tube and is introduced into the other end of the sprinkling tube. The water is introduced into the sprinkling tube from two positions to increase the volume of the water ejected from the sprinkling tube so as to cover a larger area.

Abstract: A sprinkler includes a hollow shaft to which a positioning part, a gear casing, a pipe are respectively connected to the hollow shaft. The positioning part and the pipe are respectively connected to a first end support and a second end support of a base. The positioning part has multiple grooves defined in a tubular portion thereof. A hollow positioning rod has a ratchet portion which is resiliently formed thereto. The hollow positioning rod is rotatably mounted to the hollow shaft and the ratchet portion is engaged with the grooves of the positioning part. The hollow positioning rod has a toothed portion which is engaged with an output gear of the gear casing. The gear casing is driven by a hydraulic power so as to swing the pipe periodically. The resilient ratchet portion allows the gear casing and the pipe to swing easily, and no metal spring is required.
