[0036] Working principle: first, when the height of the forklift needs to be adjusted, the hydraulic rod 3 is started. The output end of the hydraulic rod 3 is fixedly connected to the bottom of the sliding frame 4 on the front and rear sides, and as the hydraulic rod 3 is lengthened or shortened, the sliding frame 4 slides up and down in the fixed frame 2. The fixed frame 2 provides a limit for the sliding frame 4, ensuring that the sliding frame 4 moves stably in the vertical direction, and when the sliding frame 4 moves to the appropriate height, the motor 7 is started, and the output end of the motor 7 drives the bidirectional threaded rod 8 to rotate, and as the bidirectional threaded rod 8 rotates, the two forks 9 move relatively. When the forks 9 need to be forked, the staff can adjust the distance between the forks 9 according to the size of the goods. Start the motor 7, rotate the bidirectional threaded rod 8, drive the two forks 9 to move closer to each other, until the appropriate position, fork the goods, and in the process of forking the goods, the plurality of baffles 10 fixedly connected to the far side of the two forks 9 play a role in preventing the goods from falling and falling. When the forklift encounters bumps during transportation, the baffles 10 can block the goods to prevent the goods from falling off and being damaged from the forks 9, and at the same time, the sliding block 11 at the right bottom of the fork 9 cooperates with the sliding groove 12 at the left bottom of the bearing frame 5. The fixed rod 13 fixedly connected in the sliding groove 12 provides a stable sliding track for the sliding block 11. The sliding block 11 is slidingly connected to the outside of the fixed rod 13 in the middle, so that the fork 9 moves more stably.

[0037] When the goods are forked and placed on the forks 9, the force plates 19 on the top of the forks 9 will first bear the pressure. After the force plates 19 bear the pressure of the goods, the force plates 18 will be pressed. The bottom of the force plates 18 is slidingly connected inside the cavity 14, and after being pressed, it moves downward to press the sliding plates 17. The sliding plates 17 are slidingly connected outside the cavity 14, and move downward with the pressure of the force plates 18. When the sliding plates 17 move, a plurality of dampers 15 and springs 16 are compressed. One end of the spring 16 is fixedly connected to the inner wall of the bottom of the cavity 14, and the other end is fixedly connected to the bottom of the sliding plate 17. In the process of being compressed, the damper 15 absorbs the pressure generated by the weight of the goods together with the spring 16. Through the buffering action of the damper 15 and the spring 16, it can prevent the forks 9 from being damaged due to the excessive weight of the goods, and improve the durability of the device. After completing the transportation of the goods, the operator adjusts the hydraulic rod 3 according to the needs, lowers the height of the sliding frame 4, places the goods in the appropriate position, and then starts the motor 7 again to make the bidirectional threaded rod 8 rotate to drive the two forks 9 away from each other to loosen the goods.
