Hook-shaped device for tightening or loosening of eye-head screw, comprising sleeves to be used as handles

摘要

Screws with an eye-head are frequently used for tightening a pipe clamp. A first version of the device is designed as a shaft with a hook (1) at one end and a transversal handle (2) at the opposite end. A sleeve (3) loosely enveloping the shaft (1) can be held with one hand while the other turns the handle (2). In a second version the shaft (1) is bent twice (2) and two sleeves (3) can be used when operating the device. The shaft (1) is bent three times (2) and also used with two sleeves (3) in a third version.
