The invention discloses a blowout preventer bolt disassembling tool with a high-torque and low-torque switching function. The tool comprises a counter-acting force arm, a sleeve assembly, a sleeve fine-adjusting mechanism, a torque measurement mechanism, a quick low-torque mechanism, a slow-speed high-torque mechanism, a speed switching mechanism and a casing, wherein the quick low-torque mechanism and the slow-speed high-torque mechanism are both connected with the speed switching mechanism; the quick low-torque mechanism is connected with the sleeve assembly through the torque measurement mechanism, so that torque of the quick low-torque mechanism and the slow-speed high-torque mechanism can be transmitted to the sleeve assembly; the sleeve fine-adjusting mechanism is connected with the sleeve assembly, so that the angle of the sleeve assembly can be adjusted; a groove equal to a hexagonal bolt in size is formed in the front part of the sleeve assembly, and a to-be-disassembled hexagonal bolt can be sleeved
