Separately have, also comprise two sliding bearings, be arranged at described body two respectively and install in through hole, described worm screw establishes screw thread side to be arranged in this two sliding bearing.
Again, rocking bar arrange the pullover one end of ratchet-type plum blossom be provided with a control described ratchet-type plum blossom pullover clockwise or the ratchet be rotated counterclockwise turn to button.
The beneficial effects of the utility model are:
Arrange two power transmission arms, end arranges roller and flywheel knife respectively, existing pipe cutter mono-axial is regulated opening degree to change both arms into and regulates opening degree;
The driving cog design of two power transmission arm ends coordinates worm screw, reaches the aperture of original pipe cutter with vertical vortex type open-close ways, and rotary worm drives the driving cog of power transmission arm end to rotate and realizes;
Power transmission arm shape is arc, and a relative middle side part indent, form indent arc, power transmission face is large, not easily slides;
Power transmission arm is established power transmission fulcrum, be convenient to the integral-rotation of vortex type pipe cutter, realize the fly-cutting to pipeline;
Sleeve and worm screw removably connect, rocking bar one end and sleeve connection ring cross link, directly can turn also can rotate around connecting ring and turn after 90 °, then turnbarrel, drives worm screw to rotate, the rocking bar other end is that the ratchet-type plum blossom of deflection 30 ° is pullover, 360 ° of rotations are convenient to when needing, thus the cutter hub of pipe cutter and rocking bar are divided into two, highly shortened radius of turn, comply with site environment needs, and particularly solve in fire-proof and explosion-proof region, the problem producing pyrophoric hanging tube road cutting tool can not be used, facilitate in territory, fire forbidden zone, the pipeline that manpower fly-cutting needs repairing, for removing a hidden danger, safety in production provides good means, take into account the function with other original instrument simultaneously, and the former pipe cutter long number of clamping force rocker ratio doubly, cutting force is had more to tube wall, there is the simple portable advantage of structure.
