Device for moving and positioning micro-motor rotor piezoresistor

The utility model relates to a device for moving and positioning a micro-motor rotor piezoresistor. A feeding mechanism arranged on a rack transfers the piezoresistor to a feeding platform; the release mechanism arranged on the rack comprises a stop block and a second power cylinder; the feeding mechanism comprises a guide part, a guide sliding block, a clamping assembly and a first power cylinder, the clamping assembly is controlled by the first power cylinder along with the guide sliding block to slide along the guide part, the clamping assembly comprises a clamping arm and a clamp arm arranged on the sliding block, and a jacking spring is arranged between the clamping arm and the clamp arm. The clamping arms are hinged to the forceps arms through rotating shafts to be controlled to swing; the pulled end of the clamping arm touches the stop block to form the clamping jaw of the clamping arm to be opened to avoid the piezoresistor, the pressing spring presses the clamping arm to enable the clamping jaw to be
