[0020] The adjusting block 14 is provided with a connecting groove 19 corresponding to the position of the fork block 18 on one side, and the side of the fork block 18 is slidably connected in the connecting groove 19, by the arrangement of the connecting groove 19, when the fork block 18 moves, the side of the fork block 18 will move in the connecting groove 19, which is convenient for limiting the fork block 18 and preventing the fork block 18 from tilting;

[0021] The output of servo motor 3 is fixedly connected with height threaded rod 5, both ends of height threaded rod 5 are rotatably connected with fixed seat 4, one side of fixed seat 4 is fixedly connected to one side of fixed block 2, the outer thread of height threaded rod 5 is slidably connected with driving seat 6, both sides of driving seat 6 are fixedly connected with driving rod 7, one end of driving rod 7 is fixedly connected with sliding block 8, by the arrangement of driving seat 6, by driving driving seat 6 to move through height threaded rod 5, driving seat 6 can be used to drive driving rod 7 to move at the same time, which is convenient for controlling the movement of driving arm 10;

[0022] A sliding groove block 9 is slidably connected to one side of the sliding block 8. One side of the sliding groove block 9 is fixedly connected to one side of the fixed block 2. The outer arc surface of the driving rod 7 is rotatably connected to the driving arm 10. One end of the driving arm 10 is set on one side of the adjusting block 14. A rotary motor 15 is fixedly connected to one side of the adjusting block 14. A worm 16 is fixedly connected to the output end of the rotary motor 15. A worm wheel 17 is meshed at the bottom end of the worm 16. Through the arrangement of the worm 16 and the worm wheel 17, the rotary motor 15 drives the worm 16 to rotate.

When the drive seat 6 moves, it can drive the drive rod 7 to move downward. When the drive rod 7 moves downward, it can drive the sliding blocks 8 on both sides and the drive arm 10 to move downward. When the drive arm 10 moves downward, it crosses with the connecting arm 12 below, and the drive arm... 10 pushes the adjusting block 14 at one end to move forward. When the fork needs to adjust its lateral position, the rotary motor 15 can be started. The rotary motor 15 drives the worm 16 to rotate. When the worm 16 rotates, it drives the worm wheel 17 to rotate. At this time, the worm wheel 17 drives the transverse threaded rods 20 on both sides to rotate. When the transverse threaded rods 20 rotate, they drive the fork block 18 to move, so that the fork block 18 can move on the transverse threaded rods 20.
