The locking post 3 is matched with the locking hole 22, and the locking post 3 is movably connected in the locking hole 22. In this embodiment, the cavity of the locking hole 22 is frustum-shaped, and the contour of the locking column 3 is frustum-shaped. After the locking column 3 is attached to the locking hole 22, the locking column 3 and the locking hole 22 are locked. The taper of the frustum shape is set in the range of 1:15 to 1:6, which can realize the locking of the locking column 3 and the locking hole 22. Preferably, the taper of the frustum shape is set to be 1:8, the locking effect between the locking column 3 and the locking hole 22 is the best, and the locking column 3 and the locking hole 22 do not generate circumferential displacement.

The power rod 2 is rotated in the opposite direction along the support sleeve 1 and disengaged from the second locking disc 62.
The operation process of the rotating shaft locking mechanism of the embodiment is as follows:
when the handle 7 is rotated in the forward direction, the power rod 2 rotates in the threaded hole 11 of the support sleeve 1, and the power rod 2 moves relative to the support sleeve 1 towards the rotating shaft 5. The first locking disk 61 at the tail end of the power rod 2 is contacted with the second locking disk 62 at the tail end of the rotating shaft 5, and the first locking disk 61 and the second locking disk 62 are locked. Meanwhile, the locking column 3 is attached to the locking hole 22, and the locking column 3 is locked with the locking hole 22. At this time, effective locking of the rotating shaft 5 is achieved.
When the handle 7 is rotated reversely, the power rod 2 rotates in the threaded hole 11 of the support sleeve 1, and the power rod 2 moves relative to the support sleeve 1 in a direction away from the rotating shaft 5. The first locking disk 61 at the end of the power lever 2 is disengaged from the second locking disk 62 at the end of the spindle 5. Meanwhile, after the locking post 3 is slightly separated from the locking hole 22, the tension spring pulls the locking post 3 towards the tension spring assembly hole 23, so that the locking post 3 is completely separated from the locking hole 22. At this time, unlocking of the rotating shaft 5 is achieved.
As shown in fig. 10, with reference to fig. 1 to 9, the present embodiment further provides a motor maintenance workbench, which includes an operation platform 91, a support base 8 and the rotating shaft locking mechanism of the present embodiment. The operation platform 91 is connected with the rotating shaft 5 through a connecting piece 92, and the rotating shaft 5 is rotatably connected with the supporting seat 8. After the operating platform 91 is adjusted to a set angle relative to the supporting seat 8, the rotating shaft 5 can be effectively locked by positively rotating the handle 7 through the rotating shaft locking mechanism in the embodiment, so that the operating platform 91 and the supporting seat 8 keep the set angle; if the angle between the operating platform 91 and the supporting seat 8 needs to be adjusted again, unlocking can be achieved by reversely rotating the handle 7.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
