[0003] In the prior art, a patent document with publication number CN212793160U proposes a positioning fixture for automobile engine cylinder processing, including an operating mechanism and an operating table. The operating mechanism is arranged at the top of the operating table. The position of the movable plate is adjusted according to the appearance of the engine cylinder. By turning the knob, the connecting line is retracted and released. The movable plate moves with the connecting line, so that the movable plate reaches the recessed part of the engine cylinder for support, thereby improving the stability of the engine placed on the placement table. The rotated fine-tuner is pressed toward the inside of the operating table, and the stripes on the surface of the rotating shaft are inserted into the stripe groove at the lower end of the bracket. When the height of the movable plate needs to be adjusted, the fine-tuner is pulled out of the equipment and rotated, so that the fine-tuner is easy to operate and is used to stabilize the movable plate. The engine cylinder is placed on the top of the pressable plate, the compression spring is contracted, the pressable plate is inside the bottom plate, and the top of the pressable plate is at a certain distance from the top of the bottom plate, so that the engine cylinder is restricted from moving by the bottom plate, thereby ensuring that the engine cylinder does not leave the placement table.
