DETAILED DESCRIPTION

[0020] As Figure 1In the prior art, the connecting piece 2 of the existing large outdoor sunshade is locked and fixed by the elastic clamping bead 3 provided at the upper end of the support frame 1 and the clamping opening of the connecting piece 2. The upper end of the connecting piece 2 can be provided with a flared opening. When the connecting piece 2 is moved upward to the position of the elastic clamping bead 3, the connecting piece 2 is continuously moved upward to the position where the clamping opening is aligned with the elastic clamping bead 3. The compressed elastic clamping bead 3 is stretched and inserted into the clamping opening, thereby fixing the connecting piece 2 at the upper end of the support frame 1. The rod in the support 4 at the side of the connecting piece 2 is unfolded, and the unfolding of the sunshade is completed. When the sunshade needs to be folded, the user needs to press the elastic clamping bead 3 into the support frame 1 using a tool until the front end of the elastic clamping bead 3 is retracted into the inner end of the connecting piece 2, so that the connecting piece 2 can be unlocked and folded. Since the connecting piece 2 has a certain thickness, and when the sunshade is unfolded, the elastic force of the folded rod acts on the connecting piece 2, the connecting piece 2 clamped and fixed in the elastic clamping bead 3 has a downward retraction force. When the elastic clamping bead 3 is pressed, a larger force is needed to press the elastic clamping bead 3. The elastic clamping bead 3 cannot be directly pressed by fingers. The elastic clamping bead 3 cannot be pressed by fingers. Usually, a hard tool or a metal tool is needed to press the elastic clamping bead 3 to retract into the inner wall of the connecting piece 2, so that the sunshade can be folded.
