A foldable extension pipe is provided which consists of upper and lower pipe sections which are folded and unfolded. The operation input from the upper side is transmitted towards the lower side by means of the transmission rods of the upper and lower pipe sections being magnetic-coupled by first and second magnetic couplings. The measuring wheel unit and the spraying wheel unit having the foldable extension pipe are carried or stored with ease, and when a user inputs an operation via the upper portion of the extension pipe, particularly the operation input portion such as an operation lever at the grip portion of the upper portion, the operation output portion manipulates the reset switch of the counter, manipulates the nozzle section of the spray can for spraying paint, or brakes the rotary wheel.
