The head-rising mechanism has a supporting plate fixed to the main body, a head-rising bolt, a button element and a connecting shank.

The button is connected to the plate by sliding along an axis direction and leans against the head-rising bolt and can be reposited automatically. The shank is fixed to the head and has lower end surface equipped with a work state recess, a head-rising recess and a middle portion that is set between the work recess and the head-rising recess and can freely pass through the notch when the button is pressed.
