• a locking pin bracket including a top surface, at least two second lock pin holes being disposed side by side with each other in the top surface;
• a lock mounting bracket disposed vertically below the locking pin bracket and to be attached to the rotating disc, at least two third lock pin holes being disposed side by side with each other in the lock mounting bracket, the at least two third lock pin holes of the lock mounting bracket being aligned one by one with the at least two second lock pin holes in the top surface of the locking pin bracket;
• and
• at least two lock pins that are disposed vertically in parallel and side by side with each other and moveably configured to pass through the at least two second lock pin holes in the locking pin bracket and to pass through the at least two third lock pin holes aligned in the lock mounting bracket with the at least two second lock pin holes in the top surface of the locking pin bracket,
• wherein for each lock pin amongst the at least two lock pins, a first end of the lock pin is configured to pass through a corresponding first lock pin hole amongst the at least one first lock pin hole and is configured to be inserted into the lockhole, to implement locking.
