is supported in lockpin hole and path have a common boundary, big footpath on the lock pin, in work on footpath and the size of path and lockpin hole and the front apron position of arc gap on round edge edge keeping necessarily concerning, the big footpath diameter of lock pin is bigger than the diameter of the arc gap on front apron work round edge edge, its the middle footpath diameter than this arc gap again is slightly little, the a certain arc gap position of working round on lockpin hole and front apron is to timing, lock pin is under the promotion of locking spring, making wherein, the bottom of footpath section enters in the hole, big footpath of lockpin hole through the arc gap on the front apron, and top is stayed in the arc gap on the front apron, at this moment lock pin is with the locking position of regulating wheel on the circumferencial direction of work circle, make regulating wheel can not be relatively before, backboard rotates, when lock pin is extracted from lockpin hole, make wherein the footpath section abdicate the arc gap of front apron fully, and when making the path section relative with the front apron arc gap, the circle-arc tooth on the front apron can not stop regulating wheel with respect to preceding, backboard rotates.
