[0002] As a means of transportation for people, cars play a vital role in human development. Among them, the core engine of the car represents the crystallization of human wisdom. The general car engine requires many processes for processing during production. Specifically, the engine casing has processing steps such as drilling and grinding. The engine casing processing requires the use of fixtures. Fixtures play a vital role in automobile production. They are used to fix, support and position the engine casing for processing, testing or assembly.

[0003] The existing devices have some disadvantages during use. For example, when the existing engine clamp is used to fix the outer casing, its design structure often creates certain obstacles when the processing equipment is drilling. For example, the clamping part of the clamp may block or approach the drilling position, causing the processing equipment to be restricted during operation and unable to drill smoothly. This not only reduces the processing efficiency, but may also affect the drilling accuracy. In addition, for engine casings with uneven surfaces, it is often difficult for existing clamps to achieve uniform clamping force. Utility Model Content
