23rd, the 3rd elastic protrusion 24 is connected by cutting turnover or integral molded plastic with substrate 21.First elastic protrusion 22 and
Two elastic protrusions 23 are arranged on the median plane specular of the first elastic plate 211 and the second elastic plate 212；First described in a pair
Elastic protrusion 22 is located at the end both sides of first elastic plate 211 respectively, and a pair of second elastic protrusions 23 are located at described respectively
The end both sides of second elastic plate 212；And the dorsad elastic ground of bent plate 213 and the arrangement at an acute angle of the first elastic plate 211；3rd elasticity
Projection 24 is towards the elastic ground of bent plate 213 and the first elastic plate 211 or the arrangement at an acute angle of the second elastic plate 212；
First slot 14, in first cell wall 11, for being engaged with first elastic protrusion 22；
Second slot 15, in second cell wall 12, for being engaged with second elastic protrusion 23.
Before ornamental strip 3 is loaded into open slot 10, first multiple fasteners 20 are caught in open slot 10, elastic bent plate 213
With guide effect, fastener 20 is smoothly guided into inside open slot 10, the groove width of open slot 10 is less than the first bullet under nature
Property the elastic plate 212 of plate 211 and second between minimum spacing, the first elastic plate 211 and the second elastic plate 212 are extruded and respectively
The cell wall 12 of screen cloth 2 and second is touched, the related elastic protrusion 23 of first elastic protrusion 22 and second is crushed and squeezed into, finally, the
One elastic protrusion 22 and the second elastic protrusion 23 are caught in the first slot 14 and the second slot 15 simultaneously respectively.First elasticity is prominent
Play 22 engagings with the first slot 14 to squeeze into part screen cloth 2 in first slot 14, further increase the tensioning of screen cloth 2
Degree, improves the support strength of screen cloth 2, in order to accommodate the elastic protrusion 22 of screen cloth 2 and first, the groove of the first slot 14 simultaneously
Wide and groove depth is all higher than the groove width and groove depth of the second slot 15；After fastener 20 is buckled into open slot 10, the first slot 14
The end for being more than the first elastic protrusion 22 and the second elastic protrusion 23 with the spacing of notch to the bottom land 13 of the second slot 15 is arrived
The maximum spacing of elastic bent plate 213, it is ensured that fastener 20 is pressed into place by enough spaces.
Further, in installed decorating strip 3, ornamental strip 3 extrudes one or more 3rd elastic protrusions 24, makes the 3rd bullet
Property projection 24 produce elastic deformation, ornamental strip 3 is slipped between the 3rd elastic protrusion 24 and elastic bent plate 213, the 3rd elastic protrusion
24 recover deformation, ornamental strip 3 are constrained in fastener 20, it is ensured that the degree of firmly installing of ornamental strip.Meanwhile, the first elastic protrusion 22
With the modulus of elasticity of the second elastic protrusion 23, the modulus of elasticity of the 3rd elastic protrusion 24, the first elastic plate 211 and the second elastic plate
212 modulus of elasticity, the modulus of elasticity of elastic bent plate 213 successively decrease successively, along with the second slot 15 is between bottom land 13
Second cell wall 12 is provided with annular knurl, it is ensured that ornamental strip is while being squeezed into fastener 20, the first elastic protrusion 22 and the second bullet
Property projection 23 will not skid off respective slot, skid off and engage with the second elastic protrusion 23 even if there is the first elastic protrusion 22
Groove, fastener 20 is pressed against the situation of bottom land 13, as long as outwards drawing ornamental strip 3, the 3rd larger elastic protrusion 24 of modulus of elasticity
Also less first elastic plate 211 of modulus of elasticity, the second elastic plate 212, the elastic resistance of elastic bent plate 213 and annular knurl can be overcome
Frictional force, fastener is retracted again, the first elastic protrusion 22 and the second elastic protrusion 23 are caught in respective slot again.
First elastic protrusion 22, the second elastic protrusion 23, the 3rd elastic protrusion 24 are that root is wider, the narrowed taper in top
Arrangement.Bonding strength enough between each elastic protrusion and substrate 21 is ensure that, fastener 20 is reduced again in each slot
Unnecessary resistance to sliding, make multiple fasteners 20 can uniform layout in open slot 10；And ornamental strip 3 is reduced in fastener
Rotary resistance in 20, helping to twist when ornamental strip 3 is caught in fastener 20 can also be corrected, it is ensured that decoration
The overall neat degree of installation of bar 3, smoothly completes the installation of ornamental strip 3.
Embodiment two：
As shown in fig. 6, fastener 20 include substrate 21, the substrate 21 include the first elastic plate 211, the second elastic plate 212,
Connect the elastic bent plate 213 of the elastic plate 212 of the first elastic plate 211 and second；The fastener 20 also includes one or more
Externally protrude out in the first elastic protrusion 22 of the outer surface of the first elastic plate 211, one or more externally protrude out in second elastic plate
Second elastic protrusion 23 of 212 outer surfaces.Difference with the fastener in embodiment one is：Fastener in embodiment two is not provided with
3rd elastic protrusion, the end of the first elastic plate 211 and the second elastic plate 212 is bent in opposite directions into arc-shaped, and ornamental strip 3 squeezes
The gap of one elastic plate 211 and the end of the second elastic plate 212 two enters in fastener 20, forms the elasticity of similar 3rd elastic protrusion
Lattice keep off effect, are more easy to be integrally formed.
