For base 1 is fixed more stable, all be equipped with the curb plate on four sides of base. Two supports 2 are vertically arranged above the base 1, and the two supports 2 are arranged oppositely. Referring to the attached

drawings

1 and 2 in the specification, a cross rod 3 is arranged at the top of a support 2, two rubber band fixing sleeves 4 are arranged on the cross rod 3, and the rubber band fixing sleeves 4 are used for fixing the end parts of rubber bands. The rubber band fixing sleeve 4 is sleeved on the cross rod 3 and is reinforced by screws, and the rubber band fixing sleeve 4 can move along the cross rod 3, so that the width between two rubber bands is adjusted. The support 2 is formed by splicing n splicing tubes 21, n is an integer and is larger than or equal to 1, and the height of the support 2 can be adjusted according to requirements. The insertion pipe comprises an upper insertion pipe and a lower insertion pipe. The specific structure of the upper plug-in pipe is shown in fig. 5 in the specification, a clamping sleeve 213 is arranged at the top of the upper plug-in pipe, the clamping sleeve 213 is fixed at the top of the plug-in pipe, and the clamping sleeve 213 is sleeved on the cross rod 3 and is fastened by screws. This structure makes things convenient for the equipment and the dismantlement of support and horizontal pole, is convenient for store. For the fixed stability, horizontal pole 3 chooses square pole for use, and clamping sleeve 213 is square cover too. The bottom of the upper inserting pipe can be directly connected with the base 1 through threads. The specific structure of the lower insertion pipe is shown in the attached figure 6 of the specification, and the head end and the tail end of the lower insertion pipe which are connected with each other are connected through threads.

For this embodiment, two sets of rubber band supporting frames are arranged oppositely, two opposite rubber band fixing sleeves 4 are used for fixing two ends of a rubber band respectively, and the two rubber bands are stretched and stretched to be straight and arranged in parallel. The height of the rubber band can be adjusted by increasing the number of the lower insertion pipes, and the distance between the two rubber bands can be adjusted by the distance between the two rubber band fixing sleeves 4.

The length and the tensioning degree of the rubber band can be adjusted according to the specific embodiment, and the specific structure of the rubber band fixing sleeve 4 is shown in the attached figure 3 in the specification. The rubber band fixing sleeve 4 comprises a cross bar fixing sleeve 41 and a rubber band winding shaft 42. The rubber band winding shaft 42 is positioned in the winding cavity 43, and the winding cavity 43 is positioned at the rear part of the cross bar fixing sleeve 41.
