[0023] The effect achieved by the entire embodiment 1 is that when the cargo tilts backward on the forklift frame 4, the buffer plate 507 can contact the cargo in advance. At this time, the buffer plate 507 is subjected to force, which drives the hydraulic damping rod 506 to be subjected to force. At the same time, under the action of the connecting block 508 and the connecting rod 509, the movable block 505 is driven to move, and the shock-absorbing spring 504 begins to shrink due to the squeezing of the movable block 505. Under the damping action of the hydraulic damping rod 506 and the elastic force of the shock-absorbing spring 504, a certain buffering and shock-absorbing effect is achieved for the backward tilt of the cargo, thereby avoiding causing discomfort to the driver.

[0024] Example 2: Figure 1 - Figure 4 As shown, the adjustment mechanism 3 includes a fixed shell 301, which is fixedly connected to the top of the base 2. A limiting groove 302 is provided on one side of the fixed shell 301. An electric push rod 303 is fixedly installed on one side of the fixed shell 301.

When the goods tilt backward on the forklift frame 4, the buffer plate 507 can contact the goods in advance. At this time, the buffer plate 507 is forced to drive the hydraulic damping rod 506 to be forced.

The shock-absorbing spring 504 is squeezed by the movable block 505 and begins to contract. Under the damping action of the hydraulic damping rod 506 and the elastic force of the shock-absorbing spring 504, the goods are The backward tilt of the object can achieve a certain buffering and shock-absorbing effect to avoid causing discomfort to the driver. At the same time, the first infrared ranging sensor 6 and the second infrared ranging sensor 7 are set to monitor whether there are living organisms on both sides of the forklift body 1. When the pedestrian distance value is detected to be less than or equal to the safe distance, the first infrared ranging sensor 6 and the second infrared ranging sensor 7 send a signal that the pedestrian distance value is less than or equal to the safe distance to the controller 10. After receiving the signal, the controller 10 controls the activation of the alarm 8 and the alarm light 9. The alarm 8 sounds an alarm and the alarm light 9 turns on at the same time.
