above is the urdf of model. here no matter how much i change the position of the link blade, it's position don't changes from one position. image description

what should i do? i have placed its position in blender correctly. i'm using gazebo 9. when i place its position as 0 0 0 its position comes correctely but the joint position is at 0 0 0. so the problem is when ever i change the position of the joint the position of the blade link also chagnes. in rviz the model with joint position 0 0 0:
