checkbox jquery using ajax to send data and save in php not inserting

I tried to serialize rather to push the elements value but still I get the array with inserting each value 9 times in database. please anyone to help me figure out my problem this is what I am trying to

The HTML:

    <form name="chkl" id="chkl" method="post">  
                
<input type="checkbox" class="get_value" name="chk1[ ]" value="<?php echo $rows['ID'];?>">&nbsp<?php echo $rows['DESCRIPTION'];?></input><br>

<input type="submit" name="Submit" id="chk1" value="Submit"> 

JS:

<script>
 $('#chk1').click(function(){  
$('input[type=checkbox]').each( function() {
          $.post('fee_checked_save.php', $( ".get_value" ).serialize(), function(data){
          if(data == 1){
             $('#result').html(data);  
          }
      });
});
});
</script>

PHP:

<?php  
    
  $checkbox1 = $_POST['chk1'];
    if(isset($_POST['chk1']))  
    {  
    for ($i=0; $i<count ($checkbox1);$i++) {  
    $query = "INSERT INTO fee_checked(FEE_ID) VALUES ('".$checkbox1[$i]. "')";  
   $result = mysqli_query($conn, $query);
    }  
    echo "Record is inserted";  
    }  
    ?>  

Any help would be greatly appreciated. Thanks ahead of time!
