<p>A head-rising mechanism (100) is provided. The head-rising mechanism (100) is set between a main body (200) and a head (300) that is rotated around and connected with the main body (200). The head (300) has a work state and a head-rising state with respect to the main body (200). The head-rising mechanism (100) comprises a supporting plate (110) that is fixed to the main body (200), a head-rising bolt (120), a button element (131) and a connecting shank (140). The head-rising bolt (120) is connected with the supporting plate (110) by sliding along axis direction and equipped with a control surface that slops along axis direction and a givingway notch (122). The button element (131) is connected with the supporting plate (110) by sliding along axis direction and is leaned against the head-rising bolt (120) and can be reposited automatically. The connecting shank (140) is fixed to the head (300) and at its lower end surface equipped with a work recess (147) corresponding to the work state, a head-rising recess (145) corresponding to the head-rising state and a middle portion (146) that is set between the work recess (147) and the head-rising recess (145) and can freely pass through the giving way notch (122) when the button element (131) is pressed. The work recess (147) or the head-rising recess (145) is leaned against the control surface selectively.</p> |
