ABSTRACT:
A pull-type fastener setting tool is provided comprising a pistol-shaped housing having an abutment on a barrel portion for engagement with one part of a fastener and which also includes a hand-grip portion, a pulling device slidable in the housing and engageable with a pulling stem of the fastener, a rotatable handle mounted on the housing, and actuating means including a plate cam arranged to be rotated by means of the handle. The actuating means also includes a cam follower mounted on an arm pivoted on the pulling device, the arm being connected by a link which is pivoted at one end to the arm and at the other end to the housing at a remote part of the hand-grip portion. The cam follower is capable of reciprocating along an arc of large radius in response to turning of the handle without moving significantly out of alignment with the pulling device.
