The invention relates to a slidable hoisting clamp for a water pipe of a water dispenser. The slidable hoisting clamp is characterized in that the top ends of two pipe hoops provided with concave-convex shoulders are provided with a hoisting head provided with a sliding hole; and the tails parts of the two pipe hoops are separately provided with a convex head and a concave head provided with locking teeth. The slidable hoisting clamp for the water pipe of the water dispenser can be correspondingly matched with an improved product for assembly and application; design requirement is met; the aimthat the product is environment-friendly and energy-saving, lower in cost and safe is realized; assembly is simple and rapid; corrosion-resistance is high; and the service life is long.
