The opening handle assembly 7 is connected to the fifth cable 10b of the tensile structure 10, and the fourth cable 10a of the tensile structure 10 is connected to the locking structure 5. When the cab 2 needs to be flipped over, the opening handle assembly 7 is moved, and the fifth cable 10b connected to it pulls the fourth cable 10a, so that the locking structure 5 at the lower end of the front panel is unfastened, the front panel is unlocked, and the driver flips up the front panel, and then flips the cab 2 over through the lifting mechanism 3. The technical solution of the present invention is to set up a cable assembly 6, which includes a first cable 61 and a second cable 62. One end of the first cable 61 is connected to the second cable 62, and the other end of the first cable 61 is fixedly connected to the second articulated arm 21. The middle section of the first cable 61 is mounted on the first articulated arm 11, and the other end of the second cable 62 is connected to the locking structure 5. When the cab 2 is lifted, the angle between the first articulated arm 11 and the second articulated arm 21 becomes larger, and the first cable 61 is pulled, driving the second cable 62 to unfasten the locking structure 5, and the front panel is unlocked. During the lifting and flipping process, the front panel will open automatically under the action of gravity without the driver having to manually open the front panel in advance, thereby avoiding the cab 2 being flipped over without opening the front panel due to driving fatigue, negligence, and improper operation, causing unnecessary losses.

[0050] Further, in this embodiment, please refer to Figure 3 , the lock structure 5 is set to two, and is set corresponding to the two sides of the front panel assembly 4, the lock structure 5 includes a lock body 51 and a buckle body 52, the lock body 51 is set on the cab; the buckle body 52 is set on the front panel assembly 4, and the lock body 51 and the buckle body 52 are correspondingly set to two, so that the front panel can be tightly closed when locked, and can be easily opened after unlocking; the second cable 62 is provided with two, one end of the two second cables 62 is connected to one end of the first cable 61, and the other end of the two second cables 62 is respectively connected to the corresponding two lock bodies 51. When the first cable 61 is pulled, the two second cables 62 are driven to unbuckle from the corresponding two lock bodies 51, so that the front panel is unlocked and the front panel can be opened.
