TECHNICAL FIELD

[0001] The utility model relates to the field of automobile accessory transportation, in particular to a special tool car locking device for engine cylinder cover. BACKGROUND

[0002] During the manufacturing, transportation and installation of the engine cylinder cover, it is crucial to ensure the safety and stability of the cylinder cover. As one of the core components of the engine, the cylinder cover is large in size and complex in structure. Therefore, a special tool car is needed for carrying and fixing during transportation to prevent the cylinder cover from being damaged or deformed. Traditional engine cylinder cover tool cars usually use simple fixing methods, such as using ropes, clamps or bolts to fix the cylinder cover on the tool car. However, this method has many shortcomings. The traditional fixing method often fails to ensure the absolute stability of the cylinder cover during transportation, and the cylinder cover is prone to displacement or collision due to vibration or jolt, resulting in surface damage or internal structure deformation of the cylinder cover. Different models of engine cylinder covers have different sizes, and traditional tool cars cannot adapt to cylinder covers of different lengths, requiring frequent replacement of tool cars or adjustment of the fixing method, increasing transportation costs and operational difficulty. Therefore, we propose a special tool car locking device for engine cylinder cover. SUMMARY
