The invention discloses a manual chain-type pipe cutter. The manual chain-type pipe cutter is composed of a hollow rod body, a cutting mechanism, a locking connection mechanism and a driving force-applying mechanism. The cutting mechanism comprises a cutting wheel and a tool apron, the cutting wheel is arranged on a support at the bottom of the tool apron in a pivoted mode through a first pivotedrod, and the tool apron is connected to the lower end of the rod body; the locking connection mechanism comprises two idler wheels, two second pivoted rods, a sliding seat and chains; the two idler wheels are arranged on the sliding seat through the second pivoted rods correspondingly, and the two sides of the sliding seat are connected with the chains correspondingly; the driving force-applying mechanism comprises a spring, a moving seat and a chain hook, the moving seat is arranged in the rod body and can conduct linear lifting displacement along the inner wall of the rod body, two sliding grooves are formed in the rod body in the axial direction, the chain hook is arranged in a connecting hole of the moving seat in a penetrating mode, and the two ends of the chain hook extend out of therod body from the interiors of the sliding grooves; and the spring is arranged in the rod body, one end of the spring is connected with the bottom of the moving seat in an abutting-contact mode, andthe other end of the spring is connected with the tool apron at the lower end of the rod body in an abutting-contact mode. Construction is safe, and manpower, material resources and the time are saved.
