How to display plugin at the bottom of the add/edit post in admin area?

I have created one plugin which i want to display at the bottom of the add/edit post in the admin section.

I have used action as,

add_action(‘edit_page_form’,’my_function’);

but this displays the plugin in add/edit page also.which is not required for my plugin.
I only want to display the plugin box on the post page in admin area.

I have found

add_action(‘edit_category_form’,’my_function’)

add_action(‘edit_tag_form’,’my_function’)

add_action(‘dbx_post_advanced ‘,’my_function’)

but i have not found any action for post page to display the plugin only on the post page.
Any help for this?
