[0002] The blower-suction machine is an electric device used for outdoor environment cleaning. It is particularly widely used in removing fallen leaves. The main function of this equipment is to quickly and effectively clean and gather fallen leaves, reducing the burden of manual cleaning. During the working process, the blower-suction machine can blow away the fallen leaves on the ground by blowing air, thereby facilitating subsequent cleaning work. At the same time, it also has a suction function, which can suck the fallen leaves into a specially designed collection bag to achieve centralized processing of fallen leaves.

[0003] There are multiple fan blades installed inside the blower-vacuum machine, which can generate strong airflow through the fan blades. As the fan blades rotate, the air inside the blower-vacuum machine is quickly sucked in to form a low-pressure area. This low-pressure area will attract the surrounding air and tiny particles such as dust, forming a strong suction force. At the same time, the other end of the blower-vacuum machine generates high-pressure airflow through another fan blade. This airflow can quickly blow out the sucked-in dust and other particles to achieve a cleaning effect.

[0004] The existing fan blades of the blower-vacuum machine are fixed at their center points by bolts, making their installation simpler and more convenient. However, the long-term high-intensity rotation of the fan blades can easily cause the blades to loosen and be damaged, greatly reducing the service life of the blades.
