In the embodiment of the invention, the first protection net 2 is designed into a structure form with the length capable of being telescopically adjusted. In a specific embodiment, the first protection net 2 comprises at least two net bodies, and each net body is parallel to each other. Two adjacent nets can relatively slide along the distribution direction so as to realize the telescopic adjustment of the first protective net 2. Among the net bodies of the first protection net 2, the net bodies at two ends along the distribution direction of the net bodies are a first net body 3 and a second net body 4 respectively, the first net body 3 is rotationally connected with the first end of the fixing frame, and the rotation axis is perpendicular to the relative sliding direction of the adjacent net bodies. When the first net body 3 rotates relative to the fixing frame, the rest net bodies can be driven to rotate relative to the fixing frame.
Referring to fig. 3, the first protection net 2 includes two net bodies, namely a first net body 3 and a second net body 4, and the second net body 4 is directly slidably connected with the first net body 3.

In the embodiment of the invention, the net body comprises a frame and a slide bar 5, and the slide bar 5 is relatively fixed with the frame. The frame is provided with a pair of support rods 6, the axes of the pair of support rods 6 are parallel to each other, and a space is reserved between the pair of support rods 6. The sliding rods 5 are provided with at least two, the axis of each sliding rod 5 is parallel to the axis of the supporting rod 6, each sliding rod 5 is arranged between the pair of supporting rods 6, and each sliding rod 5 is distributed at intervals.
When the first net body 3 rotates to the second position, the axial direction of the sliding rod 5 is consistent with the extending direction of the slide type structure formed by the first protection net 2, that is, the axial direction of the sliding rod 5 is consistent with the sliding direction when a driver escapes, so that the smoothness during sliding escape can be ensured, and the escape efficiency is further improved.
In a further embodiment, the sliding bars 5 are distributed along an arc between a pair of supporting bars 6, the centre of curvature of which is located on the side of the net body close to the cab 1 when the first net body 3 is in the first position. When the first net body 3 is at the second position, one surface of the first protection net 2 for a driver to slide is in a chute shape, so that the problem that the driver deviates during sliding can be avoided, and the safety is further improved.
In this embodiment, when the adjacent net bodies are connected together, the support rod 6 of one of the adjacent net bodies can be made to extend into the support rod 6 of the other net body along the axial direction thereof, and the two net bodies can be ensured to slide reciprocally. At the same time, the slide bar 5 of one of the two adjacent net bodies extends into the slide bar 5 of the other net body along the axis direction of the two net bodies, and ensures that the two net bodies can slide reciprocally.
So set up, can freely slide reciprocally between the adjacent net body, first protection network 2 can freely stretch out and draw back the regulation.
