Flexible contact device of alloy analyzer

The invention discloses a flexible contact device of an alloy analyzer. The flexible contact device comprises a support, the alloy analyzer and an extrusion protection device, wherein the alloy analyzer and the extrusion protection device are fixed on the support; the extrusion protection device comprises a telescopic part and a mounting seat; the telescopic part is fixed to the support through the mounting seat; the front end of the telescopic part is connected with the alloy analyzer; the telescopic part is in signal correlation with a controller; and after the alloy analyzer is in contact with a to-be-detected sample to be extruded, the telescopic part is contracted so as to prevent the alloy analyzer from being extruded and damaged. In the structure, when a robot drives the alloy analyzer to approach an optimal analysis point, if the contact extrusion phenomenon occurs, the telescopic part is contracted so as to prevent the alloy analyzer from being damaged. The flexible contact device has the advantages
