ABSTRACT:
A hand rivet squeezer with adjustable handles includes a riveting head body, and C-shaped anvil yoke and stationary and lever swing-arm handles attached to the body. A mechanical linkage inside the body converts pivoting forces applied to the lever swing-arm into axial forces applied to a plunger pushing it from inside the body into the C-shaped yoke. The preferred mechanical linkage is a rack-and-pinion type design or alternatively a cam between the lever swing arm and the plunger. The handles are adjustable such that their angle relative the rivet head body can be varied depending on the access available around a solid rivet to be installed. The handles are engaged or locked to the body but may be unlocked or slidably disengaged and pivoted up to 90 degrees relative the body.
