[0025] It also contains:

[0026] Insertion rods 3, there are several insertion rods 3, which are respectively fixedly arranged at the right ends of several left cross bars 2, and the insertion rods 3 are movably inserted into the slots 10 opened on the right cross bar 2, and the slots 10 are fixedly provided with springs 4, and the left end of the springs 4 is fixedly connected to the insertion rods 3;

[0027] A fixed plate 5, wherein the fixed plates 5 are several in number and are respectively fixedly sleeved on several plug rods 3, and the left side wall of the fixed plate 5 is fixedly connected to the left cross bar 2 by bolts, and several threaded rods 6 are screwed on the fixed plate 5 by bearings, and a limit control mechanism 7 cooperating with the threaded rods 6 is provided on the fixed plate 5;

[0028] The movable bars 8 are in plurality and are respectively sleeved on the plurality of threaded rods 6 by screw thread connection, and the movable bars 8 are movably inserted into the strip groove 11 provided on the right side cross bar 2;

[0029] The limit control mechanism 7 comprises:

[0030] A rotating ring 7-1, wherein the rotating ring 7-1 is sleeved on the fixed plate 5 through a bearing, and an inner gear ring 7-2 is fixedly arranged on the inner ring wall of the rotating ring 7-1;

[0031] Pulleys 7-3, there are several pulleys 7-3, which are respectively fixedly sleeved on several threaded rods 6, and the pulleys 7-3 are located at the inner side of the fixed disk 5, and the several pulleys 7-3 are connected by sleeved belts;

[0033] When using the utility model, the supporting column 1 is fixed on the ground, and then the cross bars 2 on the left and right sides are moved toward the middle synchronously to shorten the distance between the cross bars 2 on the left and right sides, and the spring 4 is compressed. Then, one end of the cross bar 2 on one side is inserted into the mounting groove 9 on the supporting column 1 on one side, and one end of the cross bar 2 on the other side is aligned with the mounting groove 9 on the supporting column 1 on the other side, and then the cross bar 2 is slowly loosened. At this time, the spring 4 stretches to push the cross bars 2 on the left and right sides respectively, so that one end of the cross bar 2 on the other side is inserted into the mounting groove 9 on the supporting column 1 on the other side, and as the distance between the supporting columns 1 on both sides is different, the degree of extension of the spring 4 will also be different, so as to achieve the distance between the cross bars 2 on both sides.
