Integrated sample needle loading and stirring system

The invention discloses an integrated sample needle loading and stirring system which comprises a fixing seat (10), a stirring motor (1), a driving wheel (2), an eccentric wheel (4) and a sample needle (5), wherein the stirring motor (1) is fixed on the fixing seat (10); the eccentric wheel (4) is arranged on the fixing seat (10) through a first bearing (11); the sample needle (5) is arranged in an eccentric hole of the eccentric wheel (4) through a second bearing (6); the stirring motor (1) drives the eccentric wheel (4) to rotate through the driving wheel (2). The integrated sample needle loading and stirring system is simple and ingenious in structure and has the functions of sample loading, stirring and collision avoidance, and by using the system, equipment can be obviously simplified, and the working efficiency is improved.
