Torque output mechanism of electric spanner with fixed torque

The invention discloses a torque output mechanism of an electric spanner with fixed torque. Through the technical scheme of the invention, the torque output mechanism comprises a reverse force arm and a sleeve, wherein the reverse force arm is butted joint with a speed change mechanism through a clamping groove; one end of the sleeve is also butted joint with a planet carrier of the speed change mechanism through the clamping groove; a bearing is fixed between the reverse form arm and the sleeve; and a guide sleeve having slide fit with the sleeve is fixed on the reverse force arm. The torque output mechanism has the following beneficial effects: a connection mode between the torque output mechanism and the speed change mechanism is changed, the parts such as an output shaft, a front cover and the like are removed, and the composition of the mechanism is simplified; the improved output mechanism as a whole body is integrally butted joint with the speed change mechanism, so that the process is simplified, the
