Abstract: A pipe cutter includes two bodies connected to each other to form a first room. Each body includes a passage. One of the two bodies has a second room. A torsion spring is located in the first room and includes a mounting member and a radial opening. A blade unit includes a pin, a blade, a movable member, a spring and an action member. When activating the action member to drive the movable member to compress the spring, the third contact portion and the second engaging portion of the movable member are disengaged from the groove and the first engaging portion of the pin, and the pin is not restricted and can be removed from the passage. The blade is not restricted by the pin and replaceable.

Abstract: A pipe cutter includes a body and a cutting wheel unit. The body includes a slot, a transverse slot and a recessed area. The cutting wheel unit includes a shaft, a cutting wheel, a movable member and a resilient member. The shaft is pivotably connected to the transverse slot and includes a flange and an engaging groove. The cutting wheel is received in the slot and is pivotably connected to the shaft. The movable member is movably received in the recessed area and has an engaging portion which is engaged with the engaging groove of the shaft. The resilient member is biased between the recessed area and the movable member so that the shaft is restricted from being disengaging from the transverse slot by the movable member.
