Oil extraction device with anti-blocking function

The invention discloses an oil extraction device with an anti-blocking function. The oil extraction device with the anti-blocking function comprises an extraction device body. An oil outlet pipe is fixedly connected to the upper end of the extraction device body, and an oil inlet pipe is fixedly connected to the lower end of the extraction device body. High-pressure pumps are installed on the oil outlet pipe and the oil inlet pipe correspondingly. An oil pipe is arranged in the position, corresponding to an orifice of the oil outlet pipe, of an inner cavity of the extraction device body. Fixing rods are fixedly installed on the left side and the right side of the oil pipe. Threaded pipes are connected to the fixing rods in a sleeving mode through sliding wheels. The threaded pipes are connected with forward-reserve rotation motors in a threaded mode, and the forward-reserve rotation motors are installed on the outer wall of the extraction device body. According to the structure of the oil extraction device, p
