Spiral water injection device

The invention provides a spiral water injection device. The spiral water injection device comprises a fixed seat, a rotating shaft pipe, a motor, a carrier frame, a transmission gear set, a nut sliding block and a water injection hose, the rotating shaft tube is pivoted on the fixed seat. The motor is fixedly arranged on the fixing base and meshed with the outer wall of the rotating shaft pipe to be linked with the rotating shaft pipe. The carrier is connected with the rotating shaft tube and rotates in linkage with the rotating shaft tube, and a first guide structure is arranged on the carrier. The reciprocating screw is pivoted to the carrier, the reciprocating screw is perpendicular to the rotating shaft tube and parallel to the first guide structure, and the central axis of the reciprocating screw does not intersect with the central axis of the rotating shaft tube. The transmission gear set is connected between the rotating shaft pipe and the reciprocating screw so that the rotating shaft pipe can be in l
