Principle of the utility model: The utility model bends the two ends of the metal clip to form a contact piece, the inclination of the contact piece is basically consistent with the inclination of the vertical plate, so that the contact piece can be tightly attached to the inner side of the vertical plate, and the V-shaped part provides supporting force to the clamping foot through the contact piece; the limiting hole is arranged on the contact piece, and when the contact piece is tightly attached to the vertical plate, the limiting hole can completely cover the limiting protrusion, and the contact piece is not easy to separate from the limiting protrusion, so the matching reliability between the metal clip and the clamping foot is higher.

[0005] As an improvement, the top of the limiting protrusion is provided with an arc surface, and the bottom of the limiting protrusion is provided with a flat surface.

[0006] As an improvement, the holder is provided with limit plates on both sides of the metal clip.

[0007] As an improvement, the inner side surface of the vertical plate is provided with side baffles on both sides of the contact piece.

[0008] As an improvement, the clamping base includes a support base and a back plate arranged on one side of the support base, the support base includes a support plate, inclined plates arranged at both ends of the support plate and a fixed plate connected to one end of the inclined plate, and the clamping foot is fixed on the support plate.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The limiting hole is arranged on the contact piece. When the contact piece is close to the vertical plate, the limiting hole can completely cover the limiting protrusion, and the contact piece is not easy to separate from the limiting protrusion, so the matching reliability between the metal clip and the clip foot is higher.
