[0034] As an example of the utility model, the inner part of the cylinder 3 is rotatably provided with a rotating rod 2, the upper end of the rotating rod 2 is fixedly provided with a knob 1, the lower end of the rotating rod 2 is fixedly provided with a screw rod 9, and the surface of the screw rod 9 is threadedly connected with an internally threaded sliding rod 10. The gearbox shell is placed at the detection position, so that the positioning hole to be detected is aligned with the lower end of the cylinder 3. The depth and position of the positioning hole need to be completely corresponding to the lower end of the cylinder 3.

[0035] By rotating the knob 1, the rotating rod 2 is driven to rotate.
