By installing the silent rod 4 capable of locking the winding and unwinding mechanism 21 in the tape core assembly 2, the silent rod 4 is connected to the winding and unwinding mechanism 21 through the locking portion 41 so that the winding and unwinding mechanism 21 is in a locked state. The winding and unwinding mechanism 21 cannot rotate to retract the film tape 6 in the locked state, and the entire component is in a relatively fixed state, so that the correction tape will not make noise when it is stored or carried, thereby achieving the purpose of silencing. On the other hand, mechanical locking is achieved by the silent rod 4, and the locking is more reliable and stable, which is conducive to extending the service life.

[0028] like Figure 2 , Figure 3 and Figure 7 As shown, a positioning portion 11 adapted to the silent rod 4 is provided in the shell 1.
