[0018] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] As attached Figures 1 to 6As shown, this utility model provides a protective mechanism suitable for engineering vehicles, including a first protective device 1, a second protective device 2, and a connecting rod 3. The first protective device 1 includes a first protective cover 11, a touch switch 12, a first switch connector 13, a first lever 14, and a first elastic element 15. The touch switch 12 is located inside the first protective cover 11, the first switch connector 13 is connected to the output end of the touch switch 12, and the first lever 14 is connected to the first switch connector 13. The second protective device 2 includes a second protective cover 21, a second switch connector 22, a second lever 23, and a second elastic element 24. The second switch connector 22 is located inside the second protective cover 21, and the second lever 23 is connected to the second switch connector 22. One end of the connecting rod 3 is connected to the first lever 14, and the other end is connected to the second lever 23. One end of the first elastic element 15 is connected to the inner wall of the first protective cover 11, and the other end is connected to the first lever 14.
