At the same time, the first rotating plate 10 and the connecting block 9 rotate, and the second rotating plate 11 and the second rotating seat 12 rotate, so that the angle between the first rotating plate 10 and the second rotating plate 11 changes, and the length of the second spring 13 is stretched. The elastic force of the first spring 4 and the second spring 13 can effectively reduce the possibility of the adjusting plate 7 contacting the protective top plate 2, thereby improving the protection of the driver.
[0023] There are two adjusting rods 3, which are composed of two sleeve rods. The convex plate 5 is in contact with the bottom end of the convex block 8. There are two connecting blocks 9, which are located on the left and right sides of the convex block 8. The second rotating seat 12 is fixedly connected to the mounting frame 1, and the top of the second spring 13 is fixedly connected to the first rotating plate 10.

[0028] By using the forklift plate 18 to lift the pallet loaded with goods, the friction plate 19 contacts the bottom end of the pallet and increases the friction at the connection to improve the stability between the forklift plate 18 and the pallet. At the same time, the rotating motor 22 is started to rotate the bidirectional screw rod 23, and the two fixed clamping plates 24 slide in the slide groove 21 and approach each other, thereby clamping the bottom end of the goods on the pallet to prevent the goods from shaking when the forklift moves, causing the forklift to tilt.

[0030] The utility model provides a forklift frame with a protective structure, and the specific working principle is as follows:
[0031] When in use, the pallet loaded with goods is lifted up by the forklift plate 18, the friction plate 19 contacts with the bottom end of the pallet and increases the friction force of the connection, and at the same time, the rotating motor 22 is started to rotate the bidirectional screw rod 23, and the two fixed clamping plates 24 slide in the slide groove 21 and approach each other, so as to clamp the bottom end of the goods on the pallet, and the middle goods can be supported by the protective fence 15. When the upper goods move and fall into the cab, the goods press the adjusting plate 7 downward to rotate in the first rotating seat 6, and the convex ridge block 8 contacts and slides with the convex ridge plate 5, so that the convex ridge plate 5 presses the adjusting rod 3 and the first spring 4 downward to contract them. At the same time, the first rotating plate 10 rotates with the connecting block 9, and the second rotating plate 11 rotates with the second rotating seat 12, so that the angle between the first rotating plate 10 and the second rotating plate 11 changes, and the length of the second spring 13 is stretched.
