Wireline Bull Nose, consists of a cylinder, a spring, a pressure cap, a spring seat and a guide head. The upper end of the cylinder is connected with a cable instrument, with a spring installed inside, and the lower end is connected with a spring seat. Before connecting the spring seat, install the guide head and pressure cap. The front end of the guide head is designed in a conical shape, which is beneficial to downhole operation. When encountering resistance in downhole, the vibration of the cable instrument is slowed down by the spring.
