Under normal working conditions, the sleeve 4 and the rotating shaft 2 maintain close contact to ensure the stable rotation of the connecting block 1. However, when inspection or maintenance is required, the transmission structure 5 is required to push the two sleeves 4 toward each other to disengage them from the rotating shaft 2. When the sleeve 4 needs to be disengaged from the rotating shaft 2, the two-way screw can be rotated. Rod 9, since the screw sleeve 10 and the screw are threadedly connected, rotating the screw will cause the screw sleeve 10 to move on the screw, and this movement will drive the slide rod 11 to slide inside the fork 7, thereby pushing the fork 7 to rotate around the pin shaft. The rotation of the fork 7 pushes the sleeve 4 toward each other through the transmission rod 8, and finally causes the sleeve 4 to break contact with the rotating shaft 2. An extension ring 13 is also fixedly connected to the inner side of the sleeve 4, and the inner side of the extension ring 13 is in contact with the surface of the connecting block 1. This design can increase the contact area between the sleeve 4 and the connecting block 1, improve the stability of the connection, and can achieve the effect of squeezing and positioning the adjusted connecting block 1 when the sleeve 4 moves inward.

[0042] To sum up: this mechanical rotating device that is easy to maintain, through the combination of the connecting block 1, the rotating shaft 2, the base 3 and the sleeve 4, realizes a mechanical structure that can rotate and is easy to maintain. The connecting block 1 rotates in the sleeve 4 through the rotating shaft 2, so that the entire device has the function of rotation. At the same time, the transmission structure 5 inside the base 3 can push the sleeve 4 to move, so that it is out of contact with the wheel, which provides convenience for maintenance.
