When the forklift is running, if a collision occurs in the surrounding area, the protective plate 10 will buffer the collision. At this time, the protective plate 10 will drive the connecting block 93 to move. The movement of the connecting block 93 will be buffered by the second spring 92 and the damper 91, and while the connecting block 93 moves, it will also drive the support block 97 to rotate. The rotation of the support block 97 can drive the slider 98 to move to compress the limit groove 99. The limit groove 99 will perform secondary buffering on the impact force, which can significantly reduce the risk of collision.

[0026] The following is a detailed description of the working principle of the forklift with protective device.

[0027] like Figure 1-5As shown, during the use of the device, the operator can enter the interior of the operating room 2 to operate the device, and then move the support plate 5 to the bottom of the goods, and then start the motor 6. The motor 6 can drive the movable plate 4 to rise through the threaded rod 7. The movable plate 4 can drive the support plate 5 to rise. When the goods move to the highest point, the goods can be limited and fixed. When the goods are limited and fixed, the goods will first contact the push block 17. The goods continue to move upward to squeeze the first spring 19 and lift the movable column 18 upward. When the movable column 18 moves, it can drive the movable block 20 to move upward and drive the rotating plate 21 to rotate. When the rotating plate 21 rotates, it can drive the movable plate 12 to move and drive the stretching plate 13 to rotate, and pull The extension plate 13 will retract, and the rotation of the extension plate 13 can drive the L-shaped plate 15 to rotate on the rotating shaft 14. The L-shaped plate 15 can drive the pressure plate 16 to rotate to clamp the goods, ensuring the stability of the goods during transportation and reducing the risk of accidents caused by the collapse of goods. When the forklift is running, if a collision occurs around, the protective plate 10 will cushion the collision. At this time, the protective plate 10 will drive the connecting block 93 to move. The movement of the connecting block 93 will be cushioned by the second spring 92 and the damper 91, and while the connecting block 93 moves, it will also drive the support block 97 to rotate. The rotation of the support block 97 can drive the slider 98 to move to compress the limit slot 99. The limit slot 99 will perform secondary buffering on the impact force, which can significantly reduce the risk of collision.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
