Abstract:
1. A hand tool for inserting a selected dripper element or connector into plastic piping having various outside diameter, said tool comprising: a tool body to which a handle is connected, said handle is capable of pivoting between an upward position and a downward position with respect to the body in response to a pressure exerted on the handle, a pushing element mounted within the tool body with possibility for reciprocate movement in response to the pivoting of the handle, said reciprocate movement is associated a couple of grips, capable to be pivotably displaced with respect to the tool body when said pushing element is forced by the handle to do reciprocate movement, said grips are pivotably displaceable from an open position, in which the plastic piping can be either placed between the grips or evacuated therefrom and a closed position, in which the fixation of said plastic piping in the ready position is effected, a first spring means, which is capable to resist the pressure exerted on the handle and to return the handle into the upward position when the exerted pressure is released from the handle, a second spring means, which is capable to keep the grips in the open position and to resist to their pivotable displacement into the closed position, a couple of levers co-operating with said grips, said levers are pivotably displaceable from an open position to a closed position, the arrangement being such that when the grips are in the closed position and the levers are in the open position it is possible to effect fixation of the plastic piping having a first outside diameter, and when the grips are in the closed position and the levers are in the closed position it is possible to effect fixation of the plastic piping having a second outside diameter.
