The elastic pad gradually inclines towards the inner direction of the groove from the two ends to the center of the groove in the long axis direction; and the included angle between the surface of the elastic pad and the long axis of the groove is 15-30 degrees. Therefore, the linear change of the distance between the two elastic pads is ensured, and the resistance force of the back edge is stably increased along with the continuous increase of the insertion depth of the back edge.
The elastic pad is made of rubber or silica gel materials. The rubber can provide excellent elasticity. The silica gel is characterized by relatively hard materials, so that the back edge can quickly reach the position where the back edge cannot be inserted continuously after being inserted.
The connecting piece is in a long strip shape or a right angle shape. The rectangular connecting piece is used for conventional straight line splicing, and when the splicing position is positioned at the corner of the template, the right-angle connecting piece can be used, so that two adjacent back edges which are perpendicular to each other can be connected through the connecting piece.
Further, when the connecting piece is in a right angle shape, the position with the minimum distance between the two elastic pads is positioned at the corner of the connecting piece; the strip-shaped hole is divided into two sections and is respectively positioned at two sides of the right angle of the connecting piece.
