A second cylinder 21 is provided on one side of the second fixed block 19, and the linear motion is converted into rotational motion through the meshing of the L-shaped rack 14 and the gear 16, so that the pulled-out tree can be rotated 180° and placed on the cart 1, thereby avoiding damage to the roots of the tree due to collision during transportation and improving protection. One end of the piston rod of the second cylinder 21 is fixedly connected to the second fixed block 19, and the second cylinder 21 is fixedly connected to the cart 1 through the fixed plate 15.

[0026] Furthermore, two curved chutes 25 are provided inside the U-shaped sliding block 6, and the track lines of the two curved chutes 25 are parallel to each other. The inner surface walls of the two curved chutes 25 are slidably connected with the square slider 22 and the sliding cylinder 24. When the U-shaped sliding block 6 moves, the square slider 22 and the sliding cylinder 24 slide in the opposite direction of the movement of the U-shaped sliding block 6. When the square slider 22 slides to the lowest point of the curved chute 25, the sliding cylinder 24 slides to the highest point of the curved chute 25, and the short L-shaped gear rod 12 is connected to the rotating gear. The connecting rods 13 can rotate relative to each other, but cannot rotate otherwise. The square slider 22 and the sliding cylinder 24 are fixedly connected by a fixed connecting rod 23. A square sliding groove 7 is provided inside the long L-shaped gear rod 4. The square sliding groove 7 serves to limit the sliding trajectory of the circular sliding pin 5.

[0029] To sum up: when in use, first push the cart 1 to the front of the tree to be transplanted, push the long L-shaped gear rod 4 toward the ground, the long L-shaped gear rod 4 drives the U-shaped sliding block 6 to move together, and at the same time slides in the opposite direction of the movement of the U-shaped sliding block 6, the square sliding block 22 slides to the lowest point of the curved sliding groove 25, and the sliding cylinder 24 slides to the highest point of the curved sliding groove 25, that is, the final sliding cylinder 24 is located at the rotation axis of the short L-shaped gear rod 12 and the rotating connecting rod 13. At this time, the short L-shaped gear rod 12 and the rotating connecting rod 13 can rotate with each other, and the end is moved by rotating the long L-shaped gear rod 4 and the short L-shaped gear rod 12. Place it at a suitable position at the root of the tree and clamp the trunk, pull the long L-shaped gear rod 4 again to move it in the opposite direction of the ground, and at the same time, the square sliding block 22 slides to the highest point of the curved sliding groove 25, and the sliding cylinder 24 slides to the lowest point of the curved sliding groove 25, that is, the square sliding block 22 is finally located at the rotation axis of the short L-shaped gear rod 12 and the rotating connecting rod 13. At this time, the short L-shaped gear rod 12 and the rotating connecting rod 13 cannot rotate, start the first cylinder 2, the first cylinder 2 pulls the long L-shaped gear rod 4, and at the same time the bent disk 8 rotates counterclockwise around the cylindrical pin, the tension spring 18 is stretched, and finally the tree is pulled out. After pulling out the tree, push the long L-shaped rack 4, rotate the short L-shaped rack 12, adjust the height of the tree, and then pull the long L-shaped rack 4 to fix the position of the tree. Then start the second cylinder 21. The second cylinder 21 pushes the L-shaped rack 14 to slide forward along the T-shaped slide rail 10. At the same time, the L-shaped rack 14 drives the gear 16 to rotate 180° counterclockwise through the latching teeth, thereby driving the tree to the top of the cart 1 close to the push handle 11 and placing it, pushing the cart 1 to achieve the transfer of the tree.
