With the continuous development of the automobile industry, automobile models are increasingly more and more, and the shape, the size and the material of the engine cover also show diversified characteristics. Conventional automotive bonnet repair clips typically employ relatively simple fixed structural designs. Such clips often lack adequate flexibility in facing hoods of different vehicle types. For example, the shape and size of the clamping portion are fixed, and cannot be flexibly adjusted according to the change of the edge profile of the engine cover, so that even and stable clamping force distribution is difficult to realize when some engine covers with special shapes or large size differences are clamped. The engine hood is not only likely to displace in the repairing process, so that the repairing precision is affected, but also the surface of the engine hood is likely to be scratched, sunken and other damages caused by overlarge local stress, and the appearance quality and the overall value of the automobile are reduced. Meanwhile, the traditional clamp mostly depends on manual experience to judge and control the clamping position in the operation process, and an accurate measurement and feedback mechanism is lacked. It is difficult for an operator to accurately judge whether an optimal clamping state is reached, which makes the quality and efficiency of the repair work to a great extent restricted by human factors. Moreover, when the engine covers of different models need to be repaired, a great deal of time is often required to be spent for adjusting and adapting the clamps, so that the maintenance cost and the time cost are increased, and the requirements of the modern automobile maintenance industry on efficient and accurate repair cannot be met.
