When it is necessary to disassemble the positioning shaft 4, simply push the bending push plate 52 to compress the support spring 53, which will disengage the plug-in plate 51 from the locking slot 411, thus disassembling the positioning shaft 4. The operation is simple and convenient.

[0037] The implementation principle of the connecting rod structure for adjusting a rolling line in this embodiment is as follows: When the rolling line needs to be adjusted, the driving component cooperates with the driving rack 12 of the rack block 1 to move the rack block 1, thereby transmitting power to the part to be adjusted through the connecting seat 2 and the connecting rod assembly 3, thus realizing the adjustment of the rolling line. During the adjustment process, the connecting rod structure is firmly connected, ensuring the accuracy and reliability of the adjustment. When the equipment needs maintenance and repair, the operation is performed in the reverse order of installation. First, pull out the plug-in 7, unscrew the locking nut 6, then push the bent push plate 52 to compress the support spring 53, causing the plug-in plate 51 to disengage from the locking slot 411, and pull out the positioning shaft 4. The connecting rod assembly 3 can then be disassembled from the connecting seat 2 for easy inspection and maintenance of each component.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
