The supporting shell is a shell made of thin plates and consists of two parts, and is in a ladder shape with a small upper part and a large lower part. The upper two small covers respectively correspond to each row of two corresponding connecting holes 701 on the assembled template 400, and the small covers cover the connecting claw in a clearance way and serve as supporting pieces of the connecting claw, so that the connecting claw can slide in the supporting shell or rotate around a pin shaft as required. The lower part is a large cover shell for supporting the connecting claw, so that the connecting claw can be supported by a guiding or rotating shaft sliding in the inner part, and simultaneously, the connecting claw also plays a role of plugging two corresponding connecting holes 701 on the assembled template 400.
