How to rotate sword while still looking at mouse?

Question

I want to rotate the sword while sword is still pointing at mouse. I don't know what to use, since animations don't really work for me, and so does transform.Rotate(). This is my script:

 [SerializeField] Camera cam;
 Vector2 swordPos;
 Vector2 mousePos;

 void FixedUpdate()
 {
     mousePos = cam.ScreenToWorldPoint(Input.mousePosition);
     swordPos = new Vector2 (transform.position.x, transform.position.y);
     Vector2 lookDir = mousePos - swordPos;
     float angle = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg - 90f;
     transform.rotation = Quaternion.Euler(0, 0, angle);
 }

I also want to use: if( Input.GetButton("Fire1") )

 using UnityEngine;
 public class SwordAnimator : MonoBehaviour
 {
     [SerializeField] Camera _camera = null;
     [SerializeField] Transform _sword = null;
     [SerializeField] Vector3 _rotationPerSecond = new Vector3( 0 , 200 , 0 );
     Vector3 _dir;
     void Start ()
     {
         _dir = _sword.up;// initial dir
     }
     void Update ()
     {
         if( Input.GetButton("Fire1") )
         {
             _dir = _camera.ScreenToWorldPoint( Input.mousePosition ) - _sword.position;
         }
         float lookAtAngle = Mathf.Atan2( _dir.y , _dir.x ) * Mathf.Rad2Deg -90f;
         _sword.rotation = Quaternion.Euler(0,0,lookAtAngle) * Quaternion.Euler(_rotationPerSecond*Time.time);
     }
 }
