The invention discloses a lifting cable branch box with an adjustable angle. The lifting cable branch box includes a main body. The main body includes a branch box body and a base. The branch box bodyis located above the base. Stopping structure are fixedly installed on the four sides of the upper end of the main body. The upper end of the branch box body is provided with four groups of collars.Four groups of connection blocks are fixedly installed on the upper end of the main body. The lower ends of the four groups of connection blocks are provided with buffer structures. The stopping structure are located on the upper end of the branch box body. Two groups of angle measurement structures are arranged at the center of a waterproof partition. The stopping structures are evenly distributed on the four walls of the main body. The lifting cable branch box with an adjustable angle and a use method thereof can realize the real-time measurement of a tilt angle, reduce the workload and themeasurement cost, can adjust the angle of the branch box toimprove the measurement accuracy, have a buffer effect on the oscillating branch box body while adjusting the height and angle, and have a good prospect.
