[0005] The template connecting assembly includes two screws and four nuts. The main structure has through holes. After the screws pass through the through holes, they are fixed by nuts located on the upper and lower sides of the through holes. The tilt angle of the inclined template can be adjusted by adjusting the height of the two screws. The bottom of the screws is provided with a connector that connects to the back rib of the template.
