1. A rotatable counterweight assembly being mounted on a hose and comprising: a body including a first segment, a second segment, an outer fence formed between the first segment and the second segment; an open channel longitudinally extending along an X axis of the body and between the first segment and the second segment to define a first opening; a horizontal width of the channel along a Z axis of the body configured to place the hose in the channel, and a radial depth of the channel along a Y axis of the body configured to accommodate the hose in the channel; and an installing groove defined around the outer fence of the body and having two ends communicating with the first opening; a rotary loop rotatably fitted in the installing groove of the body and rotated toward an opening position and a retaining position, and the rotary loop including a second opening defined therein; wherein when the rotary loop is rotated toward the opening position, the second opening of the rotary loop faces to the first opening of the body and allows the hose passing through the second opening and the first opening; when the rotary loop is rotated toward the retaining position, it closes the first opening and retains the hose in the channel; wherein between the outer fence of the body and an inner fence of the rotary loop is defined a limiting structure for limiting a rotation of the rotary loop between the opening position and the retaining position and relative to the body.
