The invention provides a fishing socket for a fixed valve ball of a tubing pump and a using method of the fishing socket. The fishing socket is suitable for fishing the fixed valve ball when a fixed valve cover of the underground tubing pump of a producing well in the petroleum industry breaks and the valve ball falls into the well and enters oil jacket annulus to become a double-fish-top falling object, so that a form of the underground failing object is enabled to be simplified, and fishing of a falling string is facilitated. The fishing socket comprises an upper joint and a fishing socket body connected with the upper joint, and a valve ball capturing mechanism is fixed in the fishing socket body through a guide rail pin and can slide in the fishing socket body; a guiding shoe is arranged at the lower part of the fishing socket body, a valve is mounted on the inner walls of the two sides of a valve ball guiding track of the guiding shoe, and a ball window of the valve ball capturing mechanism is opposite to the valve. The fishing socket enters the well with the downhole string and performs fishing after circulating well washing. With the adoption of the fishing socket and the using method thereof, the success rate of working can be increased, the well occupation time of the working is shortened, and the production cost is remarkably reduced.
