The shaft body support 7 comprises a V-shaped fixing seat 71, two bearings 72 are rotatably arranged on the V-shaped fixing seat 71 in a left-right opposite manner, and the axis of the driving wheel 17 is on the symmetry plane of the two bearings 72. The two bearings 72 cooperate with the driving wheel 17 to form a three-point cooperation, so as to stably clamp the gear shaft 5. A plurality of mounting holes 61 are arranged on the support one 6 and the support two 9 in a spaced-apart manner. The shaft body support 7 and the fixing seat 10 are respectively arranged on the support one 6 and the support two 9 by means of bolts arranged in the mounting holes 61. The shaft body support 7 and the fixing seat 10 can be opposite to mounting holes 61 of different heights, respectively, so as to conveniently use the bolts to fasten and adjust the mounting height to adapt to the detection of gear shafts 5 of different lengths. The driving wheel 17 is rotatably arranged on the support plate 14. The driving pulley in the belt transmission mechanism 16 is arranged on the output shaft of the motor 15.

Then the air cylinder one 83 is elongated to drive the moving table 82 to move under the guidance of the straight-line guide rail one 81, so that the moving table 82 is attached to the curved side surface of the gear shaft 5. At this time, the laser straight-line displacement sensor 84 is above the gear arranged on the gear shaft 5. Then the motor 15 operates to drive the driving wheel 17 to rotate through the belt transmission mechanism 16. When the driving wheel 17 rotates, the gear shaft 5 rotates. At this time, the laser straight-line displacement sensor 84 detects the end surface of the shaft body support 7.
