The tool comprises of a set of different-sized easily interchangeable cylindrical blades made of steel, preferably hardened and provided with a sharpened around cutting edge, and a variety of recesses that can accommodate different sized fittings for the intent of inserting them into the piping, and a small cutting blade for cutting the irrigation piping of up to 20 mm to the required length, and a special hollow for holding start connectors during the insertion operation.
Claims10
A multifunctional handheld tool suitable for performing independently several functions, like punching holes in a plastic pipe, inserting a fitting into a hole made in the pipe, or cutting the pipe to required length, said tool comprising
- a body having a hollow main portion and a front portion, said front portion being fitted with an opening in which a replaceable tubular cutting blade is rigidly securable so as to be vis-a-vis the pipe and to punch thereof upon applying pressure on the body;
- said front portion being fitted with at least one additional opening in which a replaceable fitting is deployable so as to be vis-a-vis the pipe for insertion in the hole made in the pipe upon applying pressure to the body;
- said main portion is further provided with a cutting element, which is rigidly secured in the interior of the main portion;
- a handle, which comprises an upper portion located within the main portion of the body and a lower portion, connected to the main portion of the body, said handle is pivotable between a closed and an opened position, wherein when the handle is brought in the opened position the upper portion is distant from the cutting element and the lower portion is distant from the body and when the handle is brought in the closed position the upper portion approaches the cutting element and the lower portion approaches the body, the arrangement being such that when the handle is brought in the opened position a pipe can be placed between the cutting element and the upper portion of the handle and when the handle is brought in the closed position the upper portion urges the tube to approach the cutting element and be cut thereby.
