Constant-temperature mixing instrument positioning mechanism

The utility model discloses a constant-temperature mixing instrument positioning mechanism which comprises a shell, a mounting frame is arranged at the top of the shell, and a temperature guide plate is arranged at the top of the mounting frame; the motor mounting plate is mounted on the bottom surface of the shell, a motor is fixedly mounted on the motor mounting plate, a motor ring is mounted outside the motor, and a suction piece is mounted on the motor ring; and the electromagnet mounting base is mounted on the motor mounting plate and located on one side of the motor and the motor ring, a connecting frame is mounted on the electromagnet mounting base, and an electromagnet assembly is mounted on the connecting frame. The positioning mechanism of the constant-temperature blending instrument realizes accurate resetting through electromagnetic interaction, and the repeatability of an experiment is enhanced. The integrated heating and oscillation design improves the operation efficiency and simplifies the ste
