At present, the traditional crutches in the market are used as crutches and can also be folded into stools, but have the defects of complex structure, high cost, unattractive appearance, large size and inconvenient and troublesome use. A pipe stick is invented for solving the problems. The invention aims at bringing the convenience for the life of elders and people in need. The pipe stick can be used as a crutch for elders and can be folded into a stool when the elders go out for playing or feel tired when taking a walk so that people can rest at any time and place. The traditional train has large bearing capacity and large passenger flow volume, and seated tickets are difficult to buy, the invention can solve the problem and has smaller occupation space; meanwhile, the pipe stick can be used as a shoulder pole for taking the baggage when people go out for doing work for others, and a ball compass at the stick head can be used for directing the way.
