[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0015] The protective structure of a vertical machining center of a CNC lathe, when in use, drives the double-sided rack to move in the vertical direction by moving the lifting plate in the vertical direction. When the double-sided rack moves upward, it drives the gears on both sides to rotate. The rotating gear pulls the guide rod two to swing downward, and the middle rod is synchronously contracted in the guide rod one and the guide rod two, pulling the telescopic mechanism downward, thereby causing the protective plate to move downward. Conversely, when the double-sided rack moves upward, the protective plate moves upward.

At the same time, the spring contracts and the telescopic block is stored inside the slide plate, thereby ensuring the stability of the adjusted position of the protective plate after the height adjustment.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
