Deflection instrument for transmission shaft assembly part detection

The utility model discloses a deflection instrument for transmission shaft assembly part detection, which comprises a machine body, a moving mechanism is mounted on one side of the machine body, a second electric telescopic rod is mounted on the moving mechanism, a deflection mechanism is fixed at the tail end of a piston rod of the second electric telescopic rod, and a mounting box is fixed on the deflection mechanism. An abutting assembly is slidably mounted at the bottom in the mounting box, a reset mechanism is arranged on the abutting assembly and connected with the mounting box, a spur rack is connected to the upper end of the abutting assembly, and a second gear and a first gear are rotationally connected into the mounting box. According to the utility model, the abutting assembly can be well made to abut against the transmission shaft assembly, movement relative to the transmission shaft assembly is facilitated, accurate detection of multiple positions of the transmission shaft assembly is facilitated
