This design makes the first clamping part 102 and the second clamping part 201 smooth when sliding, reduces wear, and facilitates the connection between the first clamping part 102 and the second clamping part 201, thereby improving the stability of locking. When the second clamping part 201 rotates to the sliding channel 103, its outer edge abuts against the inner wall of the sliding channel 103, which ensures the guiding property of the second clamping part 201 when sliding, prevents shaking, improves the accuracy of sliding and the stability of control, and reduces noise and unnecessary friction. In summary, the adjustable bolt optimizes the stability and accuracy of adjustment through the precise interaction between the arc-shaped clamping part design and the sliding channel 103 of the second clamping part 201, thereby improving the overall service life and the smoothness of operation.

[0039] Furthermore, the second body 2 has a guide plane 203 , and after the second clamping portion 201 rotates to the sliding channel 103 , the outer edge of the first clamping portion 102 slides and abuts against the guide plane 203 .

[0040] In this embodiment, the second body 2 is designed with a guide plane 203. This structure increases the guiding property when the second body 2 slides relative to the first body 1, making the process of adjusting the length more stable and smooth. When the second clamping part 201 rotates to the sliding channel 103, the outer edge of the first clamping part 102 is in close contact with the guide plane 203 of the second body 2. This design ensures the precise alignment of the clamping part during the sliding process, avoids unnecessary offset, improves the accuracy and stability of the adjustment, makes the operation smoother, reduces the friction between the first clamping part 102 and the second clamping part 201, and prolongs the service life. In summary, the adjustable bolt is designed with the guide plane 203 of the second body 2, which optimizes the accuracy and stability of the clamping part when sliding, improves the accuracy of the adjustment, and improves the practicality of the adjustable bolt.

The locking bolt 4 is a newly introduced key component, which penetrates the threaded through hole 302 at the end of the third body 3 and is threadedly connected with the threaded hole 204 at the end of the second body 2. When the length of the adjustable bolt is adjusted by the first body 1 and the second body 2, the third body 3 is installed. After the third body 3 is installed, the locking bolt is tightened to firmly lock the position of the second body 2 and the third body 3 to prevent any unexpected rotation or sliding, thereby ensuring the absolute fixation of the adjustment position. In summary, the adjustable bolt provides a reliable locking mechanism for the fixation after adjustment through the design of the locking bolt 4, ensures the stability of the adjustment position, avoids loosening or disintegration of the adjustable bolt during use, and improves the stability of the adjustable bolt.

[0043] Furthermore, the length of the insertion portion 301 is longer than the length of the second body 2 .

[0044] In this embodiment, the length of the insertion portion 301 is designed to be longer than the length of the second body 2. Such a size design is intended to provide additional stability and adjustment range. The extended insertion portion 301 ensures that after the relative positions of the first clamping portion 102 and the second clamping portion 201 are locked, when the insertion portion 301 is inserted into the sliding channel 103, the insertion portion 301 can ensure that the first body 1 and the second body 2 cannot rotate relative to each other, and can maintain the stability of the structure even under large adjustments, thereby improving the overall stability. In summary, the adjustable bolt strengthens the stability and adjustment depth control during the adjustment process through the lengthened design of the insertion portion 301, adapts to a wider range of adjustment and locking requirements, and reflects the flexibility of the design and practical considerations.

[0045] Furthermore, a receiving cavity 303 is provided at the end of the third body 3 . The receiving cavity 303 is communicated with the through hole 202 . The receiving cavity 303 is used to receive the nut 401 of the locking bolt 4 .
