The utility model provides a paraffin removal device for oil well, include: haulage rope, guider, support frame, locking device and a hoist section of thick bamboo, support frame bottom rotate with the operation car to be connected, guider sets up on the top of support frame, and guider is used for leading to the haulage rope, rotate when predetermineeing the position for the operation car when the support frame, locking device is tight with support frame and operation lock. When carrying out the wax removal, the rotation support frame makes guider be in and is the position of predetermineeingthe contained angle between the horizontal plane that makes haulage rope and hoist section of thick bamboo axis place to through locking device locking support frame, prevent that the support frame from rotating for the operation car, relieve locking device to the locking of support frame after the wax removal, so it is rotatory to the neutral position who does not occupy operation car space withthe support frame, avoided support frame and guider to occupy the space on the operation car, the operation car can transport other article, and then has improved the utilization ratio of operation car.
