[0033] The working principle of the utility model is:

[0034] 1. Preparation:

[0035] Check whether the soil is too soft. If the soil is soft, install the support pad 10 on the bracket plate 7 through the screw holes. Then check whether all parts of the device are intact, ensure that the sliding sleeve 1, sliding rod 2, clamping block, adjustment device 5 and other components are not damaged, and whether the components are installed completely.

[0036] 2. Adjustment operation:

[0037] Use your foot to push up the horn part, causing the adjustment plate 9 to flip upwards, moving the adjustment screw 16 in the card slot 21 into the guide slot 20. Then rotate the operating rod 6, causing the adjustment screw 16 to slide relative to each other within the guide slot 20. After the operating angle of the operating rod 6 is adjusted, release the horn part, and the adjustment plate 9 flips downwards under its own gravity, causing the adjustment screw 16 to enter the corresponding card slot 21, thereby achieving the adjustment of the operating angle of the operating rod 6.

[0038] 3. Clamp the sapling:

[0039] Rotate the operating rod 6 towards the moving clamping block 4. At this time, the operating rod 6 is located within the card slot 21.

For the moving device, place the root of the sapling between the fixed clamping block 3 and the moving clamping block 4. Then flip the operating rod 6 towards the fulcrum direction. The operating rod 6 pulls the adjustment plate 9 to move towards the fulcrum direction, and the adjustment plate 9 drives the relative movement of the moving clamping block 4, thereby clamping the root of the sapling between the moving clamping block 4 and the fixed clamping block 3.

[0040] 4. Tree pulling operation:

[0041] Press the operating rod 6 forcefully (the force application direction is towards the fulcrum side). Through the lever principle, with the support plate 7 as the lever fulcrum, apply force to gradually pull up the sapling.

[0042] 5. Finish pulling the tree:

[0043] After the sapling is pulled out, rotate the operating rod 6 towards the moving clamping block 4 to separate the moving clamping block 4 from the fixed clamping block 3 and take out the sapling.
