When the connecting sleeve rotates, the positioning ring and the annular groove can prevent the pressure plate from rotating, so that the pressure plate is positioned by the housing of the gyroscope sensor.

[0025] In this embodiment, the inner diameter of the through hole is smaller than the width of the bottom plate on the gyro sensor 2 , so that the bottom plate on the gyro sensor cannot pass through the through hole, thereby preventing it from escaping from the through hole.
