The invention discloses a vibrating piezoelectric spray head system. The vibrating piezoelectric spray head system comprises a liquid storage cavity. A liquid supply connector is arranged above the liquid storage cavity. A liquid outlet is formed in the bottom of the liquid storage cavity. A piezoelectric ceramic vibrating mechanism used for vibrating so as to spray fluid is arranged at the bottom of the liquid storage cavity. The piezoelectric ceramic vibrating mechanism comprises an annular piezoelectric ceramic vibrating piece and a metal piece, wherein the annular piezoelectric ceramic vibrating piece and the metal piece are bonded together, convex conical holes communicating with the liquid outlet are formed in the annular piezoelectric ceramic vibrating piece and the metal piece, and a vibrating signal of the piezoelectric ceramic vibrating mechanism is guided in through an electrode on one side of the annular piezoelectric ceramic vibrating piece and an electrode on one side of the metal piece. Compared with the prior art, the vibrating piezoelectric spray head system is large in vibrating amplitude, and the problems that an existing printer spray head is prone to being blocked due to the fact that the fluid viscosity is large and is scrapped when severely blocked can be effectively solved.

Manual three-jaw chuck with three-jaw micro-movement locking devices
The invention provides a manual three-jaw chuck with three-jaw micro-movement locking devices. The manual three-jaw chuck comprises a chuck body. Three movable jaws are uniformly arranged on the uppercircumference of the chuck body. A jaw driving mechanism for driving the three movable jaws to move is arranged in the chuck body. The jaw driving mechanism comprises a butterfly bevel gear arrangedin the chuck body to drive the movable jaws to move and three bevel pinions, wherein the three bevel pinions are uniformly supported in the chuck body in the circumferential direction and engaged withthe butterfly bevel gear to drive the butterfly bevel gear to rotate. The three-jaw micro-movement locking devices are uniformly arranged on the circumference of the upper end surface of the chuck body. The three-jaw micro-movement locking devices correspond to the three bevel pinions and lock the rotation of the bevel pinions to limit the micro-movement of the three movable jaws relative to thecenter of the chuck. The manual three-jaw chuck solves the problems that the three movable jaws move outwards relative to the center of the chuck due to various factors, and the clamping force is continuously reduced, so that the workpiece clamping is not tight and the three jaws withdraw, and the problems of scrapping and flying out of the chuck caused by the untight workpiece clamping are avoided.
