[0027] The fixing mechanism 6 includes a vertical plate 601, an air pump 602, a fixing sleeve 603, a sliding shaft 604, a sealing ring 605, and a rubber block 606. The vertical plate 601 is fixedly connected to the upper surface of the driving gear 8. The air pump 602 is fixedly connected to the side surface of the vertical plate 601. The fixing sleeve 603 is fixedly connected to the lower surface of the air pump 602. The output end of the air pump 602 is in the circular hole of the fixing sleeve 603. The fixing sleeve 603 passes through the vertically penetrating circular hole of the driving gear 8.

[0029] Working principle: When it is necessary to adjust the angle of the engine on the workbench 4, turn off the air pump 602 to release the pressing of the rubber block 606 on the upper surface of the base 1. Then, drive the driving gear 8 to rotate through the rocker 10. The rotation of the driving gear 8 will drive the driven gear 2 to rotate. As a result, the driven gear 2 drives the fixedly connected rotating shaft 3 to rotate, and then drives the workbench 4 to rotate. When the engine on the upper surface of the workbench 4 is adjusted to the appropriate angle, start the air pump 602 to inflate the fixed sleeve 603 to increase the pressure inside the fixed sleeve 603. Use the pressure to push the sliding shaft 604 to press the rubber block 606 against the upper surface of the base 1, thereby increasing the friction between the rubber block 606 and the upper surface of the base 1 to fix the position of the driving gear 8 and prevent it from rotating under external force, thus fixing the angle of the engine at this time.
