The spiral springs located at the periphery are fixed together with the upper rectangular frame strip and the lower rectangular frame strip through clamping nails, respectively. A mute contact layer for reducing friction is arranged between the lower rectangular frame strip, the upper rectangular frame strip and the clamping nails.

[0006] The mute contact layer is a PVC pipe or a polyformal pipe wrapped outside the lower rectangular frame strip and the lower rectangular frame strip.

[0007] The upper rectangular frame strip and the lower rectangular frame strip are provided with a plurality of circular clamping grooves at equal distances, and the mute contact layer is a polyformal strip inlaid in the circular clamping grooves.

[0008] The utility model has the advantages that:

[0009] By wrapping a PVC pipe, a polyformal pipe or arranging a polyformal strip outside the upper rectangular frame strip and the lower rectangular frame strip, the friction between the clamping nails and the upper rectangular frame strip and the lower rectangular frame strip is reduced, and noise caused by metal friction is prevented.
