Installation tool for irrigation emitter barbs |
摘要 |
A tool installs barb emitters in irrigation tubing. The tool has a cradle which receives irrigation tubing and a punch mounted opposite the cradle. The punch has a first cylinder and a second cylinder telescopically received within the first cylinder. The first cylinder has a cap at the upper end and an annular ring extending inwardly from to partially occlude the lower end. The second cylinder includes a second cap at the upper end which slidably engages the first cylinder and is resiliently urged by a spring against the annular ring. The cap has a punch holder extending downwardly therefrom. A needle has a sharp tip extending downwardly from the punch holder through the second cap to a point within the second cylinder when the spring is fully extended and beyond the second cylinder when the spring is fully compressed. |
