Indentation mechanism of glue stapler

The invention relates to an indentation mechanism of a glue stapler. The indentation mechanism comprises a frame, and a upper pressing wheel shaft and a lower pressing wheel shaft arranged on the frame; the upper pressing wheel shaft is fixedly coated with an upper indentation wheel; the lower pressing wheel shaft is fixedly coated with a lower indentation wheel; and the upper pressing wheel shaft and the lower pressing wheel shaft are connected through a driving device. The indentation mechanism is reasonable in structural design and high in automation degree, realizes quick adjustment of indentation line positions through setting of a controller touch screen and adjustment of a servo motor, is simple in structure, stable in operation, fast and precise, and improves the book processing quality.
