Chain deflection preventing mechanism

The utility model discloses an anti-deflection mechanism for a chain. Mounting base, a driving motor is fixedly mounted on the mounting base; a rotating shaft of the driving motor is vertically upward; a mounting plate is fixedly connected to one side of a rotating shaft at the top of a shell of the driving motor; a fixing seat is fixedly mounted on one side of the mounting plate, a rotating shaftof the driving motor penetrates through the fixing seat and is fixedly connected with a chain wheel, a chain is arranged on the edge of the chain wheel, supporting blocks are fixedly connected to thetwo sides of the fixing seat, a horizontally-arranged U-shaped deviation rectifying plate is fixedly connected to the tops of the supporting blocks, and the width of the U-shaped deviation rectifyingplate is smaller than the inner diameter of the chain wheel. The deviation rectifying device is novel in structure, the U-shaped deviation rectifying plate is adopted, the chain runs more stably whenentering and exiting the ch
