[0022] Example:

[0023] Please see Figs. 1-3 The present invention provides the following technical solution: a pruning tool for Quercus acutissima, comprising an extension rod 1 and a motor 4; the bottom of the extension rod 1 is provided with a prismatic handle 2, the top of the extension rod 1 is installed with a motor 4, the bottom of the motor 4 is provided with a downwardly extending connector 5, the top of the extension rod 1 is inserted into the connector 5, and a locking bolt 6 is installed on the top of the connector 5, the locking bolt 6 being a dovetail bolt, the extension rod 1 and the connector 5 being fixed together by the locking bolt 6;

[0024] A cutting blade 7 is mounted on the motor 4 and is connected to the motor 4 in a transmission manner. A clamping head 8 and an adjusting mechanism 11 are mounted on the surface of the motor 4. The clamping head 8 is parallel to the cutting blade 7. The clamping head 8 consists of a fixed rod and a moving rod. A sliding rib 10 is installed between the fixed rod and the moving rod, and the moving rod is slidably sleeved on the sliding rib 10.

[0025] The adjusting mechanism 11 consists of an adjusting motor, a threaded rod, and a fixed base. The adjusting motor is installed on the right side of the fixed rod, and the fixed base is installed on the right side of the moving rod. The transmission end of the adjusting motor is equipped with a threaded rod, which is screwed into the fixed base. When the threaded rod rotates, it drives the fixed base to move synchronously, while the moving rod moves along the sliding edge 10. The diameter of the clamping head 8 is changed by adjusting the distance between the moving rod and the fixed rod. Multiple pulleys 9 are evenly installed on the inner sides of the fixed rod and the moving rod.

[0026] A removable battery is installed on the right side of the motor 4. Two switches 3 are installed on the handle 2, and the two switches control the motor 4 and adjust the motor respectively. The extension rod 1 is used to increase the operating length of the tool, and the diamond-shaped handle 2 at the bottom is convenient for the user to hold and operate.

[0027] The motor 4 is the power-providing component. Its top is connected to the extension rod 1 via the connector 5, and the two are fixed together using dovetail bolts as locking bolts 6 to ensure the stability of the structure. The dovetail bolts are very easy to remove and do not require an additional screwdriver.

[0028] The cutting blade 7 is connected to the motor 4 and can perform cutting action under the drive of the motor for pruning oak branches; the clamping head 8 is used to assist in the pruning operation. It consists of a fixed rod and a moving rod. The diameter of the clamping head can be adjusted by adjusting the distance between the two to accommodate branches of different thicknesses.

[0029] The pulleys 9 are evenly installed on the inner sides of the fixed rod and the moving rod. Their function is to reduce friction when clamping branches and avoid causing additional damage to the branches. Moreover, during pruning, the clamping head 8 can stabilize the branches and prevent them from swaying. The sliding ridge 10 provides a sliding track for the moving rod, ensuring that the moving rod can slide smoothly when adjusting the distance. The motor 4 and the adjusting motor are both remote control motors. They are electrically connected to the switch 3 through the Bluetooth module to achieve remote control, which is very convenient.

[0030] How this solution works:

[0031] When motor 4 starts, it drives the cutting blade 7 to rotate at high speed, using the sharp edge generated by the rotation to cut the branches of the oak tree, thereby achieving the purpose of pruning. The clamping head 8 is parallel to the cutting blade 7 and consists of a fixed rod and a moving rod. Before cutting the oak tree branches, the diameter of the clamping head 8 can be adjusted according to the thickness of the branches. The adjusting motor in the adjusting mechanism 11 is installed on the right side of the fixed rod, and the threaded rod at its transmission end is screwed into the fixed seat on the right side of the moving rod. When the adjusting motor starts, the threaded rod rotates, driving the fixed seat to move synchronously, thereby making the moving rod slide smoothly along the sliding edge 10, realizing the adjustment of the distance between the fixed rod and the moving rod, which also changes the diameter of the clamping head 8. During the adjustment process, the sliding edge 10 provides a stable sliding track for the moving rod.

[0032] Multiple pulleys 9, evenly installed on the inner side of the fixed rod and the moving rod, play a key role in clamping the branches. On the one hand, they reduce the friction between the branches and the clamping head 8, avoiding additional damage to the branches during the clamping process. On the other hand, during the cutting operation, the clamping head 8 clamps the branches tightly, and the pulleys help to keep the branches stable, preventing the branches from swaying during cutting and ensuring the smooth progress of the cutting work.

[0033] The pruning tool's motor 4 and adjustment motor are both remote-controlled motors, which are electrically connected to the two switches 3 on the handle 2 via a Bluetooth module. Users do not need to be directly close to the cutting or adjustment area; they can remotely control the start and stop of the motor 4 from a certain distance by operating the switches 3 to control the operation of the cutting blade 7, and control the adjustment motor to adjust the diameter of the clamping head 8. This remote control method greatly improves the convenience and safety of operation, especially when dealing with some dangerous or hard-to-reach branches, allowing users to maintain a safe distance from the work area.
