The key pin or the bolt connection provides a reliable way to tightly fix the bearing sleeve 1 and the jacket 3 together. This ensures the firmness of the connection and prevents loosening or falling off during operation, thereby improving the stability of the entire device. The design of using a key pin or a bolt connection makes the device easier to maintain and repair when necessary. If parts need to be replaced or adjusted, only the key pin or the bolt needs to be unfastened without complicated operations. This connection method provides a certain degree of flexibility, so that the connection between the bearing sleeve 1 and the jacket 3 can be adjusted according to specific needs. This is more adaptable to different working scenarios and processing requirements. The key pin or bolt connection is relatively simple, and the assembly of the device can be completed more quickly. This helps to improve production efficiency and reduce assembly time, thereby making the entire production process more efficient. Compared with some more complex connection methods, such as welding, key pin or bolt connection is usually more economical. This may help reduce the overall cost of manufacturing and maintaining the device. A support seat 7 is welded to the bottom end of the bearing sleeve 1, and threaded rods 6 are welded to both ends of the connecting shaft 5.

The threaded rods 6 at both ends of the connecting shaft 5 are respectively threadedly connected to the two support seats 7. A stopper 4 is provided at one end of the threaded rod 6 away from the connecting shaft 5. The existence of the stopper 4 can effectively limit the rotation of the threaded rod 6 on the connecting shaft 5. This helps prevent excessive rotation and prevent unnecessary rotation of the device during operation, thereby ensuring the stability of the working process. The design of the stopper 4 can provide additional safety to prevent the threaded rod 6 from uncontrolled rotation due to some reason (such as failure or abnormality). This helps to reduce the risk of accidents and protect operators and equipment. The stopper 4 is at one end of the threaded rod 6 and can act as a protective device to prevent the threaded rod 6 from being subjected to external impact or damage. This helps to extend the service life of the connecting element (such as the threaded rod 6). The presence of the stopper 4 can provide more precise control, ensuring that the connecting shaft 5 and the threaded rod 6 stop rotating when necessary, thereby achieving precise control of the connection position. This is important in some applications that require a specific position or angle.
