Attachment of equipment for transport

When the transport runs up to the object trigger, when you press a key in me, the script that comes to me is parental, the problem is that there is a space between them herehere is the script

Code (CSharp):

1. public class Trigger : MonoBehaviour {
2.      
3.  
4.       private void OnTriggerStay(Collider other)
5.       {
6.          
7.           if (other.CompareTag("Player"))
8.           {
9.               if (Input.GetKeyDown(KeyCode.E))
10.               {
11.                   transform.SetParent(other.transform);
12.                  
13.               }
14.           }
15.       }
16.  
17.  
18.       void FixedUpdate()
19.       {
20.           if (Input.GetKey(KeyCode.R)) {
21.               transform.parent = null;
22.           }
23.       }
24.   }

The question is, how is it possible that when you press a key, the script and the hardware will be placed in this way! Is it possible with the help of animation? Or is there another way!
