[0023] A pair of fixed connection blocks 3 and a pair of adjustable connection blocks 7 are respectively used to connect adjacent two enclosure baffles. When the adjustment assembly rotates relative to the sliding rod main body 2, it drives the pair of adjustable connection blocks 7 to rotate synchronously, so that the pair of adjustable connection blocks 7 rotate relative to the pair of fixed connection blocks 3, thereby realizing the adjustment of the connection angle of adjacent two enclosure baffles.

[0024] Please refer to Appendix Figure 1 and Appendix Figure 2 , The adjustment assembly described above includes a first sliding sleeve 4 and a second sliding sleeve 6; both the first sliding sleeve 4 and the second sliding sleeve 6 are movably sleeved on the sliding rod main body 2, and the top of the first sliding sleeve 4 is movably inserted into the bottom of the second sliding sleeve 6; a pair of adjustable connection blocks 7 are respectively fixedly arranged at the bottom of the first sliding sleeve 4 and the top of the second sliding sleeve 6, and the bottom of the first sliding sleeve 4 and the top of the second sliding sleeve 6 are respectively movably inserted into the pair of fixed connection blocks 3.

[0025] Preferably, the first sliding sleeve 4 and the second sliding sleeve 6 can adopt a cylindrical structure. The inner diameter of the first sliding sleeve 4 is slightly larger than the outer diameter of the second sliding sleeve 6, and the inner diameter of the second sliding sleeve 6 is slightly larger than the outer diameter of the sliding rod main body 2, so as to ensure the installation, lifting adjustment and rotation adjustment of the second sliding sleeve 6 on the sliding rod main body 2 and the insertion and relative lifting adjustment between the first sliding sleeve 4 and the second sliding sleeve 6.

[0026] A pair of adjusting connection blocks 7 are respectively fixed on the first sliding sleeve 4 and the second sliding sleeve 6 and move synchronously therewith, so as to realize the synchronous rotation adjustment of the enclosure baffle.

[0027] Please refer to the appendix Figure 3 , a plurality of adjusting positioning grooves 8 are formed at intervals along the circumference at the bottom of the first sliding sleeve 4, and the adjusting positioning grooves 8 penetrate downward through the bottom surface of the first sliding sleeve 4. The adjusting connection block 7 located at the bottom of the first sliding sleeve 4 is fixed in one of the adjusting positioning grooves 8, and the fixed connection block 3 located at the lower part of the sliding rod body 2 is movably inserted into another adjusting positioning groove 8.

[0028] The number of the adjusting positioning grooves 8 can be adaptively adjusted according to the size of the first sliding sleeve 4. The more the number of the adjusting positioning grooves 8, the higher the adjustable precision of the enclosure baffle.

[0029] Through the arrangement of the adjusting positioning grooves 8, the first sliding sleeve 4 is movably inserted into the fixed connection block 3 located at the lower part of the sliding rod body 2, so as to adjust the included angle between the fixed connection block 3 and the adjusting connection block 7 by using the rotation of the first sliding sleeve 4 relative to the sliding rod body 2, and further adjust the connection included angle between two adjacent enclosure baffles.

The adjusting connection block 7 located at the top of the second sliding sleeve 6 is fixed in one of the adjusting positioning grooves 8, and the fixed connection block 3 located at the upper part of the sliding rod body 2 is movably inserted into another adjusting positioning groove 8.

[0031] The number of the adjusting positioning grooves 8 can be adaptively adjusted according to the size of the second sliding sleeve 6. The more the number of the adjusting positioning grooves 8, the higher the adjustable precision of the enclosure baffle. The adjusting positioning grooves 8 on the second sliding sleeve 6 and the first sliding sleeve 4 should be vertically aligned one by one.

[0032] Through the arrangement of the adjusting positioning grooves 8, the second sliding sleeve 6 is movably inserted into the fixed connection block 3 located at the upper part of the sliding rod body 2, so as to adjust the included angle between the fixed connection block 3 and the adjusting connection block 7 by using the rotation of the second sliding sleeve 6 relative to the sliding rod body 2, and further adjust the connection included angle between two adjacent enclosure baffles.
