the supporting rod assembly 3 is provided with a plurality of groups, the groups of supporting rod assemblies 3 are arranged on the elastic tarpaulin 2 at intervals, each supporting rod assembly 3 comprises a first supporting rod 31, a second supporting rod 32 and an elastic part 33, the first supporting rod 31 and the second supporting rod 32 are all fixed on the elastic tarpaulin 2, the first end of the first supporting rod 31 and the first end of the second supporting rod 32 are located in the guide sleeve 11, the second end of the first supporting rod 31 is provided with a guide groove 311, the elastic part 33 is installed in the guide groove 311, the second end of the second supporting rod 32 is inserted into the guide groove 311, the second end of the second supporting rod 32 is abutted against the elastic part 33, and under the action of the elastic part 33, the first end of the first supporting rod 31 and the first end of the second supporting rod 32 are abutted against the bracket 1; specifically, the second end of the second support bar 32 is not fixed to the elastic tarpaulin 2;
the two pull ropes 4 are arranged, and the first ends of the two pull ropes 4 are connected to the first support rod 31 and the second support rod 32 which are close to the second end of the elastic tarpaulin 2; specifically, the pull rope 4 is a steel wire pull rope;
and the driving mechanism 5 is fixed on the bracket 1, and the driving mechanism 5 is connected with the pull rope 4 and is used for driving the pull rope 4 to pull the first supporting rod 31 or the second supporting rod 32.
Thus, the driving mechanism 5 drives the pulling rope 4 to pull, the pulling of the pulling rope 4 drives the first supporting rod 31 and the second supporting rod 32 to slide, and the elastic tarpaulin 2 is stretched; similarly, when the driving mechanism 5 releases the pulling rope 4, the elastic tarpaulin 2 retracts under the self elastic action, and the elastic tarpaulin 2 is contracted. Wherein, no matter the elastic tarpaulin 2 is in the process of stretching or shrinking, the second ends of the first and second support rods 31 and 32 are abutted against the guide sleeve 11 due to the function of the elastic member 33, when the width of the bracket 1 is increased, the second supporting rod 32 and the first supporting rod 31 slide under the action of the elastic element 33, when the width of the stent 1 becomes smaller, the second supporting rod 32 slides with the first supporting rod 31, the elastic member 33 is compressed, meanwhile, in the process of sliding the first support bar 31 and the second support bar 32, the elastic tarpaulin 2 is also stretched or contracted, so that the stretching of the canopy can be conveniently controlled according to the use requirement, meanwhile, in the process of stretching and retracting the elastic tarpaulin 2, the supporting rod component 3 can automatically change the length of the supporting rod component according to the width change of the bracket 1, so that the bracket 1 can be designed to be variable in width according to the modeling requirement.
