When putting the tree into the pit and needing to bury the roots of the tree, manually hold the control rod 2001 and pull the control rod 2001 to the right, so that the fixed shaft on the right side is driven by the fixed rod 20 to rotate, thereby driving the right side. The fixed gear 19 rotates, thereby driving the fixed gear 19 on the left side and the fixed gear 19 on the right side to rotate in the opposite direction, thereby driving the fixed rod 20 on the left side to rotate to the left. At this time, the two fixed rods 20 are opened. Similar to the V-shape, when the diameter of the tree is thicker, the opening angles of the two fixed rods 20 can be adjusted larger. When adjusted to a suitable angle, the bottom plate 1 can be manually moved to make the first fixed blocks 23 on both sides Move towards the direction close to the tree, when moving to a suitable position, now manually hold the control rod 2001 and turn the control rod 2001 to the left, so that the angle between the two fixed rods 20 is reduced, when the four fourth When a fixed block 23 was in contact with the tree, now the first fixed block 23 would be under the torsional force of the rotating torsion spring 22, and the rotating shaft 21 would rotate to the middle part and clamp the tree. The thickness of the tree is adaptively rotated. When the tree can be clamped, the limit mechanism is manually activated at this time. The limit mechanism can limit the rotation of the fixed gear 19, thereby preventing the two fixed rods 20 of the tree from moving away from the tree. Rotate so that the tree can be continuously clamped, and then the discharge mechanism can be started to fill the pit. After the root of the tree and the pit are filled, the limit mechanism can cancel the limit of the fixed gear 19, so that Release the clamping of the tree, and the tree can be clamped by the fixing mechanism, which avoids the need to manually support the tree when planting the tree, and saves human resources.
