Fluid food detection device convenient for sampling

The utility model discloses a fluid food detection device convenient for sampling, which comprises a fixed side plate fixing frame and a fixed side plate, when the fluid food detection device is used, the device is firstly moved to the side of fluid food needing to be sampled through a movable handle and a rotating wheel and then is fixed through a locking mechanism, and then a motor is started; the motor drives the threaded rod to rotate, the threaded rod drives the sliding block to move downwards along the sliding block sliding groove, the sliding block drives the sampling box fixing plate to move downwards, the sampling box fixing plate drives the sampling box to move downwards till the sampling box descends to a proper position and is completely immersed in the fluid food, then the motor is turned off, and then the electric push rod is started. The electric push rod can drive the movable piston pull rod fixing plate to move backwards along the movable piston pull rod fixing plate sliding groove, the movab
