ABSTRACT:
A clamp apparatus to hold an object to a worktable includes a guiding pole mounted to the worktable, a pressing member connected to the guiding pole, a supporting pin extending from the pressing member towards the worktable, and a resilient member connected between the guiding pole and the worktable. the pressing member is rotatable related to the worktable between a first position and a second position. The pressing member forces the object against the worktable and the supporting pin passes through the worktable in response to restoring of the resilient member when the pressing member is moved to the first position. The supporting pin abuts against the worktable to keep a disengagement of the pressing member from the object overcoming restoring of the resilient member when the pressing member is moved to the second position.
