The third surface 113 is connected to the first surface 111 and the second surface 112, and is inclined in a direction approaching the fourth surface 114 in a direction approaching the second surface 112;

the fourth surface 114, which is disposed opposite to the third surface 113, is connected to the first surface 111 and the second surface 112, and is inclined in a direction approaching the third surface 113 in a direction approaching the second surface 112;

here the third surface 113 and the fourth surface 114 are symmetrically disposed with respect to a plane between the third surface 113 and the fourth surface 114, so that the first body 11 is perpendicular to the first surface 111 and the cross section of the third surface 113 is in an isosceles trapezoid shape, which is beneficial to the processing and stability of the product, and is beneficial to the installation of the product.

The first end 115 and the second end 116 are oppositely disposed, and the first end 115 includes:

a first transition surface 1151 connected to the second surface 112 and inclined in a direction toward the second end 116 in a direction toward the first surface 111;
