Positioning question

I have head (camera)
and holster (white block) (child of camera object)

I need to keep holster (white block) always under the head with small shift left side.

holster script:

```
void LateUpdate() {
    Vector3 parentPosition = transform.parent.transform.position;
    
    parentPosition.z += -0.5f;
    parentPosition.x += -1.00f;

    Quaternion currentRotation = transform.rotation;
    transform.rotation = Quaternion.Euler(0, currentRotation.eulerAngles.y, 0);
    transform.position = new Vector3(transform.position.x, 0.7f, transform.position.z);
}


it's working fine. keeps vertival rotation of my head 

BUT if camera looks down - holster(white block) move back.. (how to avoid this)??
