Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.

Referring to Fig. 1 to Fig. 4, efficient fastener provided by the utility model comprising the first card end 100, first connection Hold the 200, second card end 300, second connection end 400, third card end 500 and two symmetrical elastic arms 600.

It is equipped with connection through-hole 110 in the upper surface at the first card end 100, connection through-hole 110 can be used for matching with joint outer part Connection is closed, connection through-hole 110 can also be used in the elastic property for improving the first card end 100, limit convenient for the first card end 100.

In addition, two sides are respectively equipped with several symmetrical reinforcing props 120 in connection through-hole 110, reinforcing prop 120 is to use In the support strength for improving the first card end 100.

In addition, the reinforcing prop 120 of two sides, which can contact with each other, to be supported when the first 100 extrusion of card end, thus Further increase support strength.

The top of first connecting pin 200 is connect with the lower surface at the first card end 100, and bottom end connects the second card end 300.

First connecting pin 200 is bar shape, be for the bayonet corresponding matching on automotive upholstery or exterior trimming parts, the One connecting pin 200 can assign in card inlet, and the first card end 100 at 200 both ends of the first connecting pin and the second card end 300 can be to vapour Interior gadget or exterior trimming parts are limited, to realize the fixation of automotive upholstery or exterior trimming parts.

The top of second connection end 400 connects the second card end 300, and bottom end connects third card end 500.
