Abstract: A sewing thread spool having thread locking and cutting functions is disclosed. The sewing thread spool comprises a winding core having an outer rim at one end and a bobbin at one end of the core, with a thread cutting plate arranged on an end plane of the bobbin. The bobbin comprises a thread-passing notch arranged at the end with the thread cutting plate. The thread cutting plate comprises a first and a second bayonet sockets separated from each other, the first bayonet socket cooperating with the thread-passing notch to produce a tension in a thread, and the second bayonet socket being used for cutting the thread and fixing the thread end. The thread spool is beneficial in that it cuts the thread and locks it to the spool.
