Claim:
1. A clamping apparatus, comprising: a machine base defining a holding plate that is adapted to receive an electronic device thereon and that is formed with an opening; left and right clamping units installed on two opposite sides of said machine base and movable relative to each other and a tension spring interconnecting said clamping units under tension; a unidirectional restriction unit installed within said base, connected operably with said clamping units and restricting said clamping units from moving toward a center of said holding plate, said restriction unit having a portion extending through said opening so as to be exposed to an exterior of said holding plate such that an applied external pressure results in withdrawal of said portion into said opening and releases said clamping units from moving, thereby permitting said clamping units to move simultaneously toward the center of said holding plate so as to clamp the electronic device tightly due to tension action of said tension spring; and a manipulating unit disposed within said base, including a gear set operably connected to said clamping units for simultaneous movement, a movable pinion disposed movably within said base, non-meshed with said gear set in a normal condition and a push element having a transmission rack meshed with said movable pinion and an manipulating part exposed to an exterior of said base such that activation of said manipulating part results in movement of said pinion to mesh with said gear set, thereby causing simultaneous movement of said clamping units away from each other and releasing the electronic device from said clamping units.
