Connecting pieces 19 are symmetrically fixed to the side walls of the two upright poles 1, and connecting holes 20 are opened through the connecting pieces 19 to facilitate the combination of several partitions into a whole.

[0028] The adjusting rod 3 has telescopic grooves 4 at its left and right ends respectively. The end of the telescopic rod 2 is movably inserted into the telescopic groove 4. The adjusting rod 3 facilitates the connection of the two uprights 1 together. A rubber sleeve 18 is movably fitted at the connection between the telescopic rod 2 and the adjusting rod 3, and the limiting ring 8 is located inside the rubber sleeve 18 to protect the gap between the telescopic rod 2 and the adjusting rod 3 and prevent dust from entering the telescopic groove 4 and affecting the performance of the bidirectional lead screw 5.

[0029] The bidirectional lead screw 5 is fixedly installed inside the adjusting rod 3, and the threads at the left and right ends of the bidirectional lead screw 5 are reversed. The two ends of the bidirectional lead screw 5 are respectively threaded into the telescopic rod 2, and the position of the telescopic rod 2 in the telescopic groove 4 is controlled by the bidirectional lead screw 5.

[0030] The movable ring 6 consists of two rings, which are symmetrically and movably mounted on the adjusting rod 3. Connecting rods 7 are symmetrically fixed on the upper and lower sides of the movable ring 6, and the connecting rods 7 are connected to the corresponding upright rod 1. The movable ring 6 and the connecting rods 7 provide support, which helps to improve the stability between the corresponding adjusting rod 3 and the upright rod 1. Several protrusions 17 are symmetrically fixed at equal angles on the outer wall of the adjusting rod 3, and the protrusions 17 are set to abut against the movable ring 6. The protrusions 17 facilitate the operator to rotate the adjusting rod 3.

[0031] Limiting ring 8, there are two limiting rings 8, which are fixedly set at the left and right ends of the adjusting rod 3 respectively, and the movable ring 6 is set to abut against the limiting ring 8 to restrict the position of the movable ring 6 and prevent the movable ring 6 from disengaging from the adjusting rod 3;

[0032] The middle part of the adjusting rod 3 is provided with a support assembly 9, which includes:

[0033] The support ring 10 is movably sleeved on the middle of the adjusting rod 3, and the upper and lower sides of the support ring 10 are respectively symmetrically fixed with support rods 11.

The ends of the two support rods 11 are respectively fixed with retaining rings 16, and the retaining rings 16 are engaged with the corresponding support blocks 13 to restrict the position of the support blocks 13 and prevent the support blocks 13 from falling off the support rods 11.

Then, the support screw 14 passes through the support block 13 and is threaded into the support hole 12 to fix the support block 13 on the support rod 11, thereby fixing the distance between the two uprights 1.
