[0002] Prayer beads, also known as rosaries, are traditionally used to count the number of beads turned on a bracelet by silently counting them. However, people often forget the number they have counted while counting, which can create a psychological burden. With the advancement of technology, electronic counters for prayer beads have emerged. However, traditional electronic counters use screws to fasten the front and back shells. When the counter's battery runs out, a screwdriver is needed to remove the screws to replace the battery. Often, when the battery is dead, there is no screwdriver available, which causes great inconvenience for replacing the battery and affects the user experience of the electronic counter.

[0003] Therefore, how to provide a ring-type counter that improves the convenience of counter battery replacement has become an urgent technical problem to be solved. Summary of the Invention
