Digital type sighting device firing angle setting device

The invention relates to a digital type sighting device firing angle setting device. A firing angle rotating screw shaft and a worm are integrally formed. The firing angle rotating screw shaft is connected with an internal tooth friction piece of a first power-off brake, and a first gear is installed on the firing angle rotating screw shaft. A spirit level is installed outside a worm gear. A second power-off brake is installed on the first gear. An internal tooth friction piece of the second power-off brake is connected with an intermediate gear shaft. A first angle sensor is installed on a fourth gear shaft, and the fourth gear shaft is connected with an internal tooth friction piece of a third power-off brake. The third power-off brake is installed on a fifth gear. A single-repairing rotating screw and a second angle sensor are installed on a sixth gear shaft. A firing angle setting switch is connected with a correction quantity setting switch, an indicator light, the first power-off brake, the second power
