[0035] In this embodiment, a rotation test device 40 is provided on the first rotating shaft 12 and the second rotating shaft 22, and each rotation test device 40 includes a detection disk 41 and a photoelectric sensor 42. The first rotating shaft 12 and the second rotating shaft 22 are respectively fixedly connected to a detection disk 41, and the detection disk 41 rotates with the first rotating shaft 12 and the second rotating shaft 22. The photoelectric sensor 42 includes a light source transmitting module and a light source receiving module, and the detection disk 41 is arranged between the light source transmitting module and the light source receiving module. A hollow portion 411 is formed on the detection disk 41, and when the hollow portion 411 rotates between the light source transmitting module and the light source receiving module, the light emitted by the light source transmitting module can pass through the hollow portion 411 to reach the light source receiving module. The light source receiving module sends a signal to the processing unit 50 according to whether the light is received, and the processing unit 50 can judge the rotation of the first rotating shaft 12 and the second rotating shaft 22 by judging the signal of the light source receiving module.

The power generated by the first motor 13 is transmitted to the first rotating shaft 12 through the lateral transmission mechanism 14, and then drives the endoscope to rotate the handwheel left and right through the first clamping part 11, so that the endoscope insertion part completes the left and right rotation. The power generated by the second motor 23 directly drives the endoscope to rotate the handwheel up and down through the second rotating shaft 22 and the second clamping part 21, so that the endoscope insertion part completes the up and down rotation. Therefore, the endoscope insertion part testing device provided by the present invention can simultaneously control the left and right rotating handwheel and the up and down rotating handwheel of the endoscope, so as to automatically realize the simultaneous rotation of the endoscope insertion part in multiple directions without mutual interference, reduce the work intensity, and reduce the cost.
[0040] Furthermore, by setting the rotation test device 40, the angle between the hollow portion 411 on the detection disk 41 and the initial position can be pre-adjusted to set the rotation angle of the first rotating shaft 12 and the second rotating shaft 22. When the first rotating shaft 12 and the second rotating shaft 22 rotate by a preset angle, the hollow portion 411 rotates between the photoelectric sensors 42, and the processing unit 50 controls the motor to stop or reverse according to the signal transmitted by the rotation test device 40 to perform a test of a specified number of times and a specified bending angle. That is, by setting the rotation test device 40, the rotation angle and the number of rotations can be set, and the endoscope insertion portion can be tested efficiently and uninterruptedly.
