[0035] Among them, the guide rod 203 is fixedly connected to the lifting plate 107, and is slidably connected to the moving block 106, and passes through the moving block 106; two guide rods 203 are arranged on one lifting plate 107, so that when the moving block 106 moves, it can drive the lifting plate 107 to move synchronously, and then drive the positioning plate 108 to move synchronously, and at the same time enable the lifting plate 107 and the positioning plate 108 to slide up and down on the moving block 106.

[0036] Secondly, the mounting plate 207 is fixedly connected to the lifting plate 107 and is located on the top of the lifting plate 107; the rubber pad 208 is fixedly connected to the mounting plate 207 and is located on one side of the mounting plate 207; the rubber pad 208 is in contact with the surface of the engine cylinder head to prevent the positioning plate 108 from scratching the surface of the engine cylinder head.
