Through adopting above-mentioned technical scheme, when alternate adapter sleeve or connector on the bag body, through exerting effort to the pulling-on piece, can make things convenient for the interlude of adapter sleeve or connector.

Furthermore, a protective edge is arranged on the edge of the rope outlet.

Through adopting above-mentioned technical scheme, the setting of safe edge can avoid going out the rope mouth and cause the destruction under the friction of annular rope circle.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the elastic lug on the connector is clamped with the connecting sleeve and assisted by the through hole on the folding flanging, so that the purpose of conveniently replacing the annular rope ring is achieved;

(2) the spring pin is further matched with the plug hole, so that the installation of the connector and the connecting sleeve can be enhanced;

(3) through setting up the trompil, can exert the effort through the trompil on through-hole to adapter sleeve and connector to make things convenient for adapter sleeve or connector to alternate between folding turn-ups and the bag body.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

The utility model provides a stretching strap formula plastic bag, as shown in figure 1, 2, including the bag body 1, fix at the bag mouth department of the bag body 1 and the folding turn-ups 2 of lower limb and bag body 1 fixed connection, install annular rope circle 3 in folding turn-ups 2 and the intermediate layer position of the 1 upper end of the bag body, two play rope mouths 4 have been seted up with the intermediate layer position of the 1 upper end of the bag body to folding turn-ups 2, annular rope circle 3 forms the closed loop through the connector 5 of fixing on it with adapter sleeve 6, it has the elastic convex block 7 with 6 looks joints of adapter sleeve to extend on the connector 5, folding turn-ups 2 are arranged along its length direction and are established and have been seted up a plurality of through-holes 8.

Furthermore, the through hole 8 is oval, so that the edge line of the through hole 8 can be prevented from having stress-concentrated corners, and the damage to the through hole 8 is small.

It should be noted that, in order to further strengthen the firmness of the edge of the through hole 8, the edge of the through hole 8 in the present embodiment is fixed with the convex ring 9.
