The angle and length can be adjusted according to the children of different ages to facilitate drinking water and moving hands, and the water cup can be placed to prevent the water in the water cup from becoming cold and undrinkable in winter. The arm can be fixedly supported in different positions and different environments to avoid the hand from having no support point and causing the hand to move randomly and cause the needle to move, and the flow rate can be adjusted according to different liquids. Therefore, a utility model is proposed to solve the above problems. Utility Model Content
