AI Technical Summary
Existing protective devices for ancient and famous trees are large in size, inconvenient to operate, and lack adjustment flexibility, making it difficult to adapt to the different shapes and angles of various ancient trees, resulting in poor support effects.
By employing the gripper and support device in the fixing device, and utilizing a self-locking structure composed of a two-way screw, ratchet, pawl and return spring, combined with a double-headed screw adjusting rod, reliable self-locking of the gripper and angle adjustment of the support block are achieved, adapting to the growth conditions of different ancient tree branches.
It provides stable and secure protection, meets individual needs, expands the scope of application, prevents the device from accidentally loosening or falling off, and adapts to complex branch and trunk shapes.
