Attach to other coordinat SpringJoint2D from code. Here is code.

 using UnityEngine;
 using System.Collections;
 //var object1 = "Block(1)";
  
 public class NewBehaviourScript : MonoBehaviour 
 {
     private SpringJoint2D myLight;
     public Vector2 connectedAnchor;
     
     void Start ()
     {
         myLight = GetComponent<SpringJoint2D>();
         //var object1 = "Block(1)";
     }
     
     
     void Update ()
     {
         if(Input.GetKeyUp(KeyCode.Space))
         {
             //myLight.enabled = !myLight.enabled;
           connectedAnchor = new Vector2(4.8F,4.0F);
         }
     }
 }
