Shelves lower surface is provided with T-shaped groove, and T-shaped groove groove top is provided with more than two location sphere shrinkage pools, and lower balance shelves upper end is set
Being equipped with T-shaped projection is used to coordinate T-shaped groove, and T-shaped convex center position, which is provided with blind hole, blind hole, is provided with stage clip and spheroid, ball
Body is located on stage clip, and in the T-shaped projection insertion of lower balance shelves in the T-shaped groove of balance shelves, spheroid upper end heads into T-shaped groove groove top
Location sphere shrinkage pool in so that above balance shelves, lower balance shelves formed close contacting fit slidable connection.If desired will
The dynamics of key is turned down, and upper balance shelves are adjusted to the direction for being oriented to shelves, if necessary to which the dynamics of key is tuned up, is only needed
The direction of upper balance shelves to key tail shelves is adjusted.So that its height adjustment for balancing shelves is simple to operate and high
Degree adjustment is accurately and reliably.
