When the jaw gripper 602 is pulled, the bite gap between the jaw gripper 602 and the jaw support 601 increases. Refer to the instruction manual for details. Figure 3 As shown;

[0030] When the gripper 602 is pressed, the occlusal gap between the gripper 602 and the tooth base 601 decreases. Refer to the instruction manual for details. Figure 4 As shown.

[0031] In summary, this invention changes the bite gap of the entire biting assembly 6 by applying damped pressure or pulling and rotating the gripper 602. In practical use, it provides dynamic adjustment of the bite gap, offering free rotation and opening / closing adjustment capabilities. The bite gap can be dynamically adjusted according to different paper thicknesses, making it suitable for use with paper of varying thicknesses.
