WORKTABLE SLIDING BLOCK POSITIONING MECHANISM

摘要

A worktable sliding block positioning mechanism includes abuse member pivotally connected to a sliding block, a first clamping block affixed to the base member and defining a first clamping end that is disposed at one side relative to the worktable, a second clamping block pivotally connected to the base member and defining a second clamping end that is disposed at an opposite side relative to the worktable and opposite to the first clamping end, and a drive wheel pivotally connected to the base member and rotatable by an external force and defining a press portion that is pressed on the second clamping block to move the second clamping end toward the first clamping end of the first clamping block upon a rotary motion of the drive wheel. Thus, the worktable sliding block positioning mechanism avoids deformation or displacement of the sliding block during its positioning.

1. A worktable sliding block positioning mechanism pivotally coupled to a sliding block that is movable along a fixed sliding rail of a worktable, the worktable sliding block positioning mechanism comprising:
a base member pivotally connected to said sliding block; a first clamping block affixed to said base member, said first clamping block defining a first clamping end disposed at one side relative to said worktable; a second clamping block pivotally connected to said base member, said second clamping block defining a second clamping end disposed at an opposite side relative to said worktable and opposite to said first clamping end; and a drive wheel pivotally connected to said base member and rotatable by an external force, said drive wheel defining a press portion pressable on said second clamping block to move said second clamping end toward said first clamping end of said first clamping block upon a rotary motion of said drive wheel.
