An exemplary clamping apparatus includes a supporting body, a plurality of clamping units installed on the supporting body, a PWM controller, and a detection unit. Each clamping unit includes a magnet, a clamping pin, an electrical coil, and a coil core mechanically engaged with the clamping pin. The magnet is configured for holding the clamping pin at a target position. The PWM controller is configured for supplying a pulse signal to the respective electrical coil of each clamping unit and for thereby creating a magnetic force causing a corresponding coil core and a corresponding clamping pin to, synchronously, move. The detection unit is configured for detecting a back electromotive force representative of the arrival to the target position of a clamping pin and signaling the PWM controller to stop supplying the pulse signal. A clamping process utilizing the clamping apparatus is also provided.

A print head includes a nozzle plate, a fixing plate fixed to the nozzle plate, an oscillation sheet, and a security assembly. The fixing plate defines a receiving groove. The oscillation sheet is fixed between the fixing plate and the nozzle plate and covers the receiving groove. The security assembly includes a fixing component, an elastic component, a fixing element, an anti-detachable component, and a pointed tip extending from a distal end of the anti-detachable component. The security assembly is fixed to the fixing plate, the elastic component and the anti-detachable component are received in the receiving groove with the pointed tip pointed towards the oscillation sheet. A first end of the compressed elastic component resists against the fixing component and a second end of the elastic component resists the anti-detachable component.
