The folding bracket is very popular with people because of being foldable, reducing the volume and being convenient to carry, and is widely applied to outdoor sun-shading devices, drying devices, folding traffic isolation frames, display devices and the like as the bracket. Particularly, in recent years, with the continuous improvement of living standard of people, more and more people like going out for camping on holidays. When camping, people like building a sun-shading device to avoid sunshine and get a better rest. Common sunshade devices, such as awning, folding tent, camping tent, etc., generally include a sunshade cloth and a support, and the sunshade cloth is connected to the support to play the role of sunshade and wind shielding. However, the outdoor solar protection devices of prior art has following not enough in the in-service use, particularly speaking, for the canopy, need rely on two or many spinal branch vaulting poles to support, peg graft through grafting structure between the bracing piece, need fix the four corners of canopy through the ground nail in addition, this just leads to the canopy fixed point to take up an area of great, and can only fix on ground softer if lawn or sandy soil ground to the place requirement is higher, and the buildding of canopy is comparatively troublesome, need many people to cooperate jointly, it is comparatively inconvenient to operate. The folding awning is provided with four telescopic stand columns, the folding frames are connected between the tops of adjacent stand columns, the support of the folding awning can stand by itself after being unfolded, but when the support is folded by one person, the folding frames around the top of the support of the folding awning interfere with each other, the folding operation is inconvenient, two persons are generally required to cooperate to fold the four telescopic stand columns together, and the folding process is inconvenient and laborious; moreover, this folding sunshade all needs the folding leg to install between the adjacent stand top because of its structural constraint, consequently is comparatively heavy, portable not convenient to carry, and materials are more, the cost is on the high side, can not satisfy the personal or domestic sunshade demand comparatively lighter. Like a camping tent, the tent has a small volume when being folded, but when the tent is unfolded during use, a user needs to support the tent by building a large rigid structure bracket, and the process of building the bracket is very troublesome; and after using, the user need tear the support open again and connect into a branch pole, therefore the operation is wasted time and energy, and user experience is relatively poor. For another example, a small tent is often found in daily life, and the small tent generally adopts a flexible frame structure, and a cloth is wrapped on the outer circumference of the flexible frame structure, so as to form a small tent. However, such a small tent has relatively poor stability and self-standing property. During the use process, a large amount of nailing ropes are needed for fixing, but the small tent cannot be fixed on the hardened ground.

The side stay bars 106 of the two groups of support frames 1 can ensure that the sunshade cloth arranged at the top of the support frames extends all the way to be arranged on the side stay bars 106, thereby increasing the sunshade area and improving the connection firmness of the sunshade cloth. And one end of the upper side top rod 107 is hinged with the second hinge point 105 of the support frame 1, so that the side stay 106 can synchronously rotate to fold or unfold in the process of the movement of the second hinge point 105, and the support frame 1 can be synchronously folded or unfolded. Other technical solutions of this embodiment are the same as those of the first embodiment, so repeated descriptions are not provided in this embodiment.

Example five:

see fig. 9 and 10; in the embodiment, the support frames 1 are also arranged in two groups, and the projections of the first hinge point 104 and the second hinge point 105 of each group of support frames 1 in the vertical direction are overlapped; each group of the support frames 1 further comprises a third support rod 108 and a pull rod 109 which are arranged on the outer side of the support frame 1, the upper end of the third support rod 108 is hinged with the first hinge point 104 of the support frame 1, the lower end of the third support rod 108 is on the same horizontal plane with the lower end of the first support rod 100 or the second support rod 101, one end of the pull rod 109 is hinged with the second hinge point 105 of the support frame 1, and the other end of the pull rod 109 is hinged with the third support rod 108; and a locking mechanism 3 which can keep the position of the second hinge point 105 fixed when the support frame 1 is in the unfolding state is connected between the first hinge point 104 and the second hinge point 105 of each group of support frame 1, or a locking mechanism 3 which keeps fixed when the telescopic structure 2 is in the unfolding state is connected on the telescopic structure 2. Therefore, each support frame 1 consists of three support rods, and the three support rods form a stable triangular support, so that the standing stability and the wind resistance of the portable folding support are improved; furthermore, the third rod 108 is hinged to the second hinge point 105 of the support frame 1 through a pull rod 109, so that the first rod 100, the second rod 101 and the third rod 108 can be folded or unfolded synchronously. This locking mechanism 3's setting makes the support remain stable when portable folding support expandes, avoids unexpected touching and automatic folding, and the security is good. Other technical solutions of this embodiment are the same as those of the first embodiment, so repeated descriptions are not provided in this embodiment.
