[0019] Specifically, when this tree pruning and leaf collection device is in operation / use: loosen the clamping bolt 404 to separate it from the first protective cover. At this time, the second protective cover 402 can be rotated until the blade protrudes from the notch. Then tighten the clamping bolt 404 to fix the position of the second protective cover 402, preventing it from moving during the cutting process and affecting the collection of leaves or the pruning of branches. The device is carried on the operator's back by the shoulder strap 103. The shoulder strap 103 is connected to the outer wall of the handrail 100 through a fixing block, which can ensure the stability of the device during use, prevent the pruning accuracy from being affected by hand shaking, and distribute the weight of the device, effectively reducing the operator's workload. At the same time, the operator holds the first handle 104 and the second handle 105. The second handle 105 has a start switch, and the handrail 100 is equipped with a storage battery. The start switch, the storage battery, and the drive motor 101 form a series circuit to prepare the circuit for subsequent power output. When the trimming operation is completed and the equipment needs to be moved or stored, the blade notch on the first protective cover should be covered. During operation, loosen the clamping bolt 404, rotate the second protective cover 402 to cover the blade notch, and then tighten the clamping bolt 404 to fix the first protective cover and the second protective cover 402 relative to each other. At this time, the cutting blade can be covered. In this state, the cutting blade 300 is not exposed, which can effectively avoid the safety hazards caused by the exposed blade during the movement or storage of the equipment, and at the same time protect the cutting blade 300 from external collision damage.
