navigation using hector_slam odometry and amcl not working

edit

hi ,

i'm trying to get odometry from hector_slam by using hokuyo laser because the odometry that i'm getting from wheel encoder is not so good , so i configured the hector_slam and i'm getting a good odometry data , these odometry data are used by amcl to get localization but the problem is that when i'm trying to navigate i'm getting a wrong localization
here is an exemple of what i'm getting , what do you think it's causing troubles ?

when the robot turn i'm getting this :

and here is the launch file i used to get the navigation :

  <launch>
  <!--laser stuff-->
  <node name="hokuyo" pkg="hokuyo_node" type="hokuyo_node" >   
  <remap from="/scan" to="/scan" />
  <param name="scan" value="scan" />
  <param name="frame_id" value="base_laser"/>
  </node> 

  <arg name="odom_frame_id"   default="odom"/>

here is the launch file i used to get odometry from hector :

</node>
</launch>

@pengjiawei here is the node that provide tf between odom and base_link :

#!/usr/bin/env python
import rospy, tf, tf2_ros, geometry_msgs.msg, nav_msgs.msg

def callback(data, args):
  bc = tf2_ros.TransformBroadcaster()
  t = geometry_msgs.msg.TransformStamped()

  t.header.stamp = rospy ...
