Unable to place block "y" axis +1 in the "Right Click" json

Using the "Right Click" json I'm trying to make my custom tongs pick up an item and able to place the item picked up elsewhere. It's all working so far, but there is a minor inconvenience happening whenever I place the item(Block). Which ever block I place the item(Block) on whether specified or not specified, the block being targeted (being looked at) gets replaced by my placed block.

Is there a way to specify my block to just spawn "y" axis +1, so that it spawns on top of the block I'm looking at whenever I right click? I went through the wiki and tried many things, but nothing worked.

My only fix currently is an extensive one in which I would turn my "tongs2" into a block, then use the "placeEvents" json to changed the placed block into the block of my choice, according to the tag applied to the "tongs2" block.
