Abstract: A long-handled spray gun with a rotary head has a connector head, a rotary member, a fixed member, a connection, part, a long tubular rod, a block, a fixing bolt, a large and a small ring washers and a flexible locating member wherein the rotary member screw joined to the connector head at one side is pivotally engaged with the fixed member with the large and small ring washers adapted therein and the flexible locating member inserted into one of locating slots of the rotary member for proper location thereof, and the connection part is coupled with the fixed member and the long tubular rod at both ends respectively. The fixing bolt is adapted to pivotally engage the rotary member with the fixed member thereof and the block having a serrated polygonal flange disposed thereon is matched to a serrated polygonal fixing head of the fixed member, preventing the fixing bolt from coming off when the rotary member thereof are pivotally rotated. Via the rotary member, the connector head can be easily and quickly adjusted stepwise into a proper angle for use.

Abstract: A coupling head and connecting tube assembly structure comprises a coupling head having an external-threaded section to fit to a connecting tube wherein the coupling head has a hollow bore extending through the interior to which the connecting tube is joined therewith. Furthermore, the connecting tube has the internal surface synchronically pressed by multiple dotted-punching forces so that the internal surfaces of both connecting tube and coupling head synchronically depressed by the dotted-punching forces exerting thereon can form multiple positioning points that are reciprocally bound to each other so as to combine the coupling head and connecting tube into one unit, facilitating easy and speedy assembly thereby.

Abstract: A telescopic tube with water supply is equipped with a minor tube, a major tube that are connected to each other by a tubular coupling device which has a registration end and a connecting section, the former is engaged with one end of the minor tube and the latter is engaged with the top end of the major tube. A guard cap is secured to the top end of the major tube which serves to prevent the minor tube from easy disengagement from the major tube in case of excessive extension adjustment. The connecting section of the tubular coupling device has a cone shaped configuration with a spiral thread track defined thereon and terminates in a stop board. A pair of support halves having tapered inner surface are movably registered with the spiral thread track and are outwardly expanded or retracted as moving against the cone shaped connecting section so that the outer surface of the support halves can be urged against the inner side of the major tube to hold the same in place in length adjustment and vice versa for retraction of the telescopic tube. Thus the telescopic tube can be adjusted of its length and secured in place by simple rotation of the major tube and moving the minor tube to make the adjustment easy, speedy and precise.

Abstract translation: 具有供水的伸缩管配备有小管，主管通过具有配准端和连接部的管状联接装置彼此连接，前者与小管的一端接合，并且 后者与主管的顶端接合。 保护帽固定在主管的顶端，用于防止小管在过度延伸调整的情况下容易脱离主管。 管状联接装置的连接部分具有圆锥形构造，其中限定有螺旋形螺纹，并且终止于止动板。 具有锥形内表面的一对支撑半部可移动地与螺旋形螺纹轨迹对准，并且随着抵靠锥形连接部分移动而向外扩展或缩回，使得支撑半部的外表面可以被推靠在主体的内侧 管子在长度调节中保持相同的位置，反之亦然，用于缩回伸缩管。 因此，伸缩管可以通过主管的简单旋转并移动小管来调节其长度并固定在适当的位置，使得调节容易，快速和精确。
