Be provided with regulating wheel between the said blade shaft and second bearing pin.

Said second bearing pin is provided with through hole, and said connecting rod runs through said through hole, and the corresponding second bearing pin position of said connecting rod is provided with positioning sleeve, and the two ends of the corresponding positioning sleeve of said connecting rod are respectively equipped with nut, and said nut is threaded with connecting rod.

Said spacing push rod is provided with second nut of threaded engagement with it, frame be welded with one with the transition piece of push rod threaded engagement, when second nut is screwed and transition piece offset.

The rear of said frame is provided with the plate that connects material.

The utility model has the advantages that: the matching relationship that 1, utilizes pedal, connecting rod and U-shaped knife rest; Realize pressing down and resetting of U-shaped knife rest; The motion of U-shaped knife rest drives blade pipe fitting is cut, and the rotation of blade drives pipe fitting simultaneously and cooperates rotation with spring bearing, pipe fitting cutting one-time-reach-place; Efficient is high, and is time saving and energy saving; 2, avoided the injury of blade to the operator, safety in utilization is good; 3, second nut on the spacing push rod of adjusting can be controlled depth of cut; But 4, be provided with the location-plate that horizontal sliding is regulated, the requirement of being convenient to cut the different length pipe fitting; 5, the nut on the adjusting connecting rod can be regulated the stroke size that the U-shaped knife rest presses down and resets, and satisfies the process requirements of different tube diameters.
