[0033] The working principle and usage process of the present invention: When in use, the ship shafting to be clamped is placed on the top of the support body 1 between the adjusting cylinders 4. The opposite surfaces of the two adjusting cylinders 4 are set as arc surfaces, which is convenient for clamping the shaft. According to the clamping requirements, the adjusting cylinder 4 is moved up and down by the adjusting rod 5 to adjust the height of the adjusting cylinder 4 to adapt to shafts of different diameters and ensure the stability of clamping. At the same time, the adjusting cylinder 4 is moved left and right by the cooperation of the movable slot 2 and the movable block 3 to adjust the distance between the adjusting cylinders 4. Then, the sliding rod 7 is moved into the positioning slot 8 to position the adjusting cylinder 4. At this time, the pressing block 12 moves with the sliding rod 7 to apply a downward pressing force on the lifting rod 11, and the lifting rod 11 moves downward into the interior of the slot 16 to perform the plugging and positioning work on the adjusted movable block 3. During the working process of the sliding rod 7, the fixing plate 91 performs magnetic attraction positioning work through the magnetic sheet 92 and the fixing strip 93. After the clamping and supporting work of the support body 1 is completed, the sliding rod 7 is pulled out of the positioning slot 8. At this time, the spring 14 pushes and resets the lifting rod 11 through the connecting piece 15 and the reset slot 13, so as to realize the function of adjusting the clamping diameter of the support body 1 and improve the adaptability of the ship shafting support body 1.

Due to different batches of ship shaftings, which are respectively applicable to ships of different volumes, the diameter of the ship shafting will change with the batch of the ship shafting. When the diameter of the ship shafting is too large or too small, the support cannot effectively support and position the ship shafting, and it is not possible to better adjust the support diameter. It is necessary to prepare multiple models of supports to support different batches of ship shaftings, reducing the adaptability of the ship shafting support.
