Description
Technical field
The utility model relates to a kind of cutter, especially relates to a kind of fast advance and retreat metal tube cutter.
Background technology
The metal tube cutter is a kind of for the hand cutting tool that cuts off metal pipe material, has convenient and in the advantage of carrying.The metal tube cutter comprises main body and movable carriage, movable carriage is slidingly mounted on the main body, the half-nut wedge is installed in the movable carriage, one screw mandrel is installed in the installing hole of main body and movable carriage jointly, screw mandrel and half-nut wedge are by being threaded, the outer peripheral face of screw mandrel of the prior art is the full thread structure, when the half-nut wedge is subjected to the screw mandrel pulling force, pulling force is more big, it is also just more big to produce laterally thrust, cause the installing hole inner surface to produce vestige and damage because of the screw thread friction, thereby influenced the function of fast advance and retreat.
The utility model content
Technical problem to be solved in the utility model is: a kind of fast advance and retreat metal tube cutter is provided, has not only realized the fast advance and retreat blade, and can protect the inner surface of screw mandrel installing hole, improved flexibility and the service life of metal tube cutter fast advance and retreat.
For solving the problems of the technologies described above, the technical solution of the utility model is: fast advance and retreat metal tube cutter, comprise main body, be slidingly fitted with movable carriage on the described main body, be rotatablely equipped with two rollers that be arranged in parallel by a roller shaft respectively on the described main body, be rotatablely equipped with blade by blade shaft on the described movable carriage, the half-nut wedge is installed in the described movable carriage, one screw mandrel is installed in the installing hole of described main body and movable carriage jointly, one end of described screw mandrel is provided with knob, described screw mandrel and described half-nut wedge are by being threaded, described half-nut wedge is slidingly mounted in the described movable carriage, be provided with back-moving spring between described half-nut wedge and the movable carriage, the outer peripheral face at described screw mandrel two ends is the shiny surface suitable with the inner surface of the installing hole of described main body and movable carriage.
Preferably, described half-nut wedge is provided with half-nut wedge guide rail, is provided with the half-nut wedge gathering sill that cooperates with described half-nut wedge guide rail in the described movable carriage.
Adopted technique scheme; the beneficial effects of the utility model are: because the half-nut wedge is slidingly mounted in the movable carriage; be provided with back-moving spring between half-nut wedge and the movable carriage; the outer peripheral face at screw mandrel two ends is the shiny surface suitable with the installing hole inner surface of main body and movable carriage; when screw mandrel rotates; the shiny surface of screw mandrel contacts with the inner surface large tracts of land of installing hole; avoided the installing hole inner surface to be worn; therefore; the utility model has not only been realized the fast advance and retreat blade; and can protect the inner surface of screw mandrel installing hole, flexibility and the service life of having improved metal tube cutter fast advance and retreat.
