As an optimal technical solution, in order to facilitate the rotation of the threaded rotating rod so that the positioning and fixing plate can be moved accurately, which is conducive to accurate positioning of the engine body and reduces machining errors, the end of the threaded rotating rod is provided with a rotating handle in a vertically folded structure.

Compared with the prior art, the utility model has the beneficial effects:

1. This processing fixture is equipped with a movable positioning and fixing plate, which can be applied to the processing of various processes of different types of engine bodies. It has a wide range of applications, reduces the number of positioning, thereby improving the processing accuracy, and this fixture is stressed by the plate to the engine body. Clamping to achieve uniform force, reduce deformation, and high clamping stability.

2. The threaded rotating rod is connected to the positioning and fixing plate through the connecting piece, so that the positioning and fixing plate is convenient to move on the groove, so as to realize the rapid positioning and fixing of the engine body, which is beneficial to improve the processing efficiency of the engine body.

3. The end of the threaded rotating rod is provided with a rotating handle in a vertically folded structure. The threaded rotating rod can be easily rotated without effort, so that the positioning and fixing plate can be moved accurately, which is conducive to accurate positioning of the engine body and reduces processing errors.
