Pipe cutter

A pipe cutter comprising:

• a body having a passage and a transverse slot defined in a first end thereof, the transverse slot communicating with the passage, an axial slot defined axially in a second end of the body and located corresponding to the passage, a transverse hole defined through a wall of the slot, a rail connected between the first and second ends of the body, a recessed area defined in a side of the first end of the body and communicating with the transverse hole, a locking hole defined in an inner bottom of the recessed area, a cap reception recess defined in an opening of the recessed area;
• a cutting wheel unit having a shaft, a cutting wheel, a movable member, a resilient member, a cap and a pin, the shaft pivotably extending through the transverse hole and having a flange formed on a first end thereof, an engaging groove defined in a second end of the shaft, the cutting wheel located in the axial slot and having an axial protrusion through which the shaft extends, the axial protrusion located between the engaging groove and the flange, the movable member movably received in the recessed area, the movable member having an engaging portion defined in a first end thereof, and a receiving portion defined in a second end thereof, an inner surface of the engaging portion engaged with the engaging groove, a lever extending laterally from a second end thereof, the lever extending beyond the body, the resilient member received in the receiving portion and being biased between an inner end of the recessed area and the movable member so that the movable is restricted from being disengaging from the transverse hole, when the lever is pulled to move the movable member to compress the resilient member, the inner surface of the engaging portion is disengaged from the engaging groove, the cap engaged with the cap reception recess and having a notch with which the shaft is engaged, the cap having a recess and an aperture, the lever extending through the recess, the aperture located corresponding to the locking hole, the pin extending through the aperture and connected to the locking hole to fix the cap to the cap reception recess;
• a slidable unit having two seats, two axles, two rollers and a locking member, each seat having a sliding slot, two pivotal portions and a connection portion, the rail slidably engaged with the sliding slots, each axle extending through an axial hole of each of the rollers, two ends of each of the axles pivotably connected to the two respective pivotal portions of the two seats such that the two rollers are located corresponding to the cutting wheel, the locking member extending through the two respective connection portions of the two seats to fix the two seats;
• a threaded rod unit having a threaded rod, a knob and a connector, the knob connected to a first end of the threaded rod which has threads defined in a shank thereof, the shank is rotatably and movable extending through the passage when rotating the knob;
• a control unit having a controller, a button and a bolt, the controller located on one side of the threaded rod and received in the transverse slot, the controller having a toothed portion which is engaged with the threads of the shank of the threaded rod, an axis of the toothed portion being parallel to an axis of the threaded rod, the controller being restricted from disengaging from the transverse slot by the threaded rod, the controller having a protrusion, the protrusion and the toothed portion located on the same side of the controller, the protrusion having a threaded hole, the button connected to the controller and located in the transverse slot, the button partially extending beyond the body, the button contacting the protrusion, the bolt extending through the button and threadedly connected to the threaded hole of the controller to connect the controller to the button, and
• a resilient member received in the transverse slot and biased between an inside of the transverse slot and the controller to engage the toothed portion with the shank, when the button is pushed, the controller moves inward and compresses the resilient member to disengage the toothed portion from the shank.
