The region 22 has a plurality of reinforcing structures 23 in the shape of horizontal grooves. One side adjacent to the end edge 21 is orthogonally formed with a conical positioning insert 24 at the upper and lower positions, and an elastic hook 30 is formed on the other side of the area 22 . Two elastic pieces 31 , the two elastic pieces 31 extend along the horizontal direction of the area 22 , each of the elastic pieces 31 includes a positioning portion 32 and a connecting portion 33 , the positioning portion 32 is fixed to the area 22 , the two The connecting portion 33 is jointly connected to a hook 34 , and the hook 34 is also suspended on the area 22 and faces between the two positioning inserts 24 .

The elastic piece 31 is a transverse S-shaped, the connecting portion 33 is defined as a first curved segment 311, and the connecting portion 32 is defined as a second curved segment 312, the radius of curvature of the first curved segment 311 is smaller than the The radius of curvature of the second curved section 312 . The positioning portion 32 includes a support base 321 and a resistance base 322, the support base 321 is connected to the end of the second bending section 312, and the resistance base 322 is parallel to the horizontal direction and supports against the second bending section 322. Outside of curved section 312 . The connecting portion 33 is cylindrical, which can increase its structural strength and avoid breaking therefrom. The hook 34 includes a first guide surface 341 and a second guide surface 342. The length of the first guide surface 341 is greater than that of the second guide surface 342. The second guide surface 342 faces the area 22. The surface 341 faces away from the region 22 , and the first guide surface 341 and the second guide surface 342 intersect at an obtuse angle. The second guide surface 342 is a toothed surface.

As shown in FIG. 6 and FIG. 7 , the panel 1 is combined with the equipment column 40 , and the equipment column 40 is preset with a plurality of positioning holes 41 . The user inserts the index fingers of both hands into the finger attachment space 15 , that is, the index finger and thumb can hold the finger attachment portion 14 . Position the panel 1 relative to the front of the equipment column 40, after the positioning plugs 24 at both ends correspond to the selected positioning holes 41 respectively, push the panel 1 towards the direction of the equipment column 40, and the edge 42 of the equipment column 40 pushes against the hook. The first guide surface 341 of the buckle 34, the hook 34 presses the elastic sheet 31 backward by the pushing force, and after the first guide surface 341 passes the edge 42 of the equipment column 40, the elastic sheet 31 slightly rebounds, so that the The two guide surfaces 342 resist the edge 42 of the device column 40 .
