The upward movement of the adjusting threaded rod 203 drives the linkage plate 301 to move upward. The upward movement of the linkage plate 301 drives the linkage gear plate 302 to move upward. The upward movement of the linkage gear plate 302, through meshing, drives the linkage gear shaft 303 to rotate. The rotation of the linkage gear shaft 303 drives the connecting rotating rod 401 to rotate. The rotation of the connecting rotating rod 401 drives the connecting roller 402 to rotate. After the connecting roller 402 rotates, it can be easily... The connecting roller 402 is removed from the connecting rod 401. The rotating motion of the connecting rod 401 drives the rotating shaft 403 to rotate. The rotating shaft 403 drives the mounting top plate 404 to rotate. The rotating motion of the mounting top plate 404 drives the spring-loaded inclined block 501 to move linearly inside the locking groove 107 through the inclined surface of the spring-loaded inclined block 501. The linear motion of the spring-loaded inclined block 501 compresses the spring-loaded spring 503. After the connecting shaft 403 moves past the spring-loaded inclined block 501, the elasticity of the spring-loaded spring 503 drives the spring-loaded inclined block 501 to move linearly. After the spring-loaded inclined block 501 moves linearly, it can lock the connecting shaft 403 to prevent the connecting roller 402 from shifting during the winding process.
