Abstract:
A toggle lever clamping device comprising:a bearing head (15) terminally arranged on an actuator (2);a pivot unit (16) having a clamping arm (22), the pivot unit is pivotally mounted for movement (17) about a pivot axis between a release position and a clamping position;an actuating rod (12), plunging into the bearing head (15) of the actuator (2);an intermediate member (24) articulated at a first bearing point (25) with the actuating rod (12) and at a second bearing point (27) with the pivot unit, the second bearing point spaced a distance from the pivot axis (17) of the pivot unit;an abutment face (48) being provided on the bearing head (15) wherein the abutment face (48) is positioned in the path of motion of the pivot unit (16) and cooperates with the pivot unit (16) for presetting the clamping position; andwherein the actuator is extendable to a first position in which the clamping arm is moved to the clamping position, and the actuator is further extendable to a second position beyond the first position such that the clamping arm is securely retained in the clamping position.
