Cordless Clamping Handle Tubing Cutter Tool

A tubing cutter tool for cutting tubing comprising;

• a. a gear drive mechanism having an input gear rotatably coupled to the output shaft of a rotary motor and at least one output gear rotatably coupled to a cutting mechanism, said gear drive mechanism having a forward extending base plate in which is disposed a rearward extending slot for receiving a length of tubing to be cut,
• b. a cutting mechanism having a generally circular-shaped cutting head, said cutting head having extending into an outer circumferential wall surface thereof a radially disposed slot alignable with said slot in said base plate of said gear drive mechanism for receiving a length of tubing to be cut, said cutting head having at least one cutting blade movable into said slot and bear against an outer circumferential wall surface of a length of tubing within said slot and traverse a circular path on said tube surface as said cutting head is rotated to thus make a circumferential severing cut in said tubing,
• c. a clamping handle extending from said gear drive mechanism, said handle having a clamping mechanism for exerting a clamping force on a length of tubing to thereby maintain said length of tubing in a fixed position within said slot of said cutting head while said cutting head rotates to make a severing cut in said length of tubing,
• d. an electric motor mounted fixedly to said handle and having an output shaft coupled to said input gear of said gear drive mechanism,
• e. a battery compartment fastened to said handle for holding a battery,
• f. electrical conductors which connect power terminals of said battery compartment to said drive motor, and
• g. an on/off switch connected in series with at least one of said conductors and said drive motor.

In a tubing cutter tool including a cutting mechanism provided with an opening fro receiving a length of tubing to be cut, the improvement comprising;

• a clamping handle extending from said cutting mechanism, said handle having a clamping mechanism for exerting a clamping force on a length of tubing to thereby maintain said length of tubing in a fixed position within an opening in said cutting mechanism while said cutting mechanism rotates to make a severing cut in said length of tubing, said clamping handle comprising;
• a. a first, fixed longitudinally elongated, generally semi-cylindrically-shaped rear handle shell which is fixedly mountable to a cutting mechanism of a tubing cutter having an opening for receiving a length of tubing, said fixed rear handle shell having a longitudinal axis coaxially alignable with said cutting mechanism opening,
• b. a second, longitudinally elongated generally semi-cylindrically-shaped pivotable front handle shell pivotably mounted with respect to said fixed rear handle shell and pivotable towards said rear handle shell to form between opposed longitudinally disposed faces of said front and rear handle shells an elongated generally cylindrically-shaped cavity for receiving a length of tubing to be cut, and
• c. at least one releasable clamping fastener for releasably holding said front and rear handle shells in compressive contact with a length of tubing received between said handle shells.
