Transform translate not working properly in Canvas

     private void OnTriggerEnter2D(Collider2D collision)
     {
         collision.gameObject.transform.SetParent(transform);
         collision.GetComponent<DragHandler>().enabled = false;
         collision.gameObject.transform.Translate(transform.position); 
     }

I want to set collided object's position to base object's position. But collided object's position not set properly in canvas.
