The lower end of the adjustment frame 3 is rotatably connected to the bottom surface of the fork arms 2. The rack body 1 is equipped with a drive motor 5 and a guide frame 4. The adjustment frame 3 and the guide frame 4 are slidably arranged. The drive motor 5 is used to drive the adjustment frame 3 to rotate. When the adjustment frame 3 rotates, the lower end of the adjustment frame 3 drives the fork arms 2 to swing up and down.

[0020] The rack body 1 is connected to the front of the forklift body. This application omits the drive components of the forklift body and the fork arms 2. The number of adjustable frames 3 is not less than the number of extension arms.

[0021] like Figure 4 As shown, an auxiliary frame 6 is provided on the front side of the main body 1 of the shelf. The fork arm 2 is rotatably connected to the bottom of the auxiliary frame 6. The end of the fork arm 2 adjacent to the main body 1 of the shelf is connected to a vertically arranged auxiliary frame 7, which is movably arranged inside the auxiliary frame 6.

[0022] When the adjusting frame 3 drives the fork arm 2 to adjust the pitch, the auxiliary frame 7 swings inside the auxiliary frame 6.
