[0013] In summary, the utility model has the following beneficial effects:

[0014] 1. When the battery pack is installed on the handle, first, the plug-in end on the upper side of the battery pack is embedded in the plug-in slot of the plug-in seat in the horizontal direction, wherein the long groove on the plug-in end side is for the plug-in strip on the inner wall of the plug-in slot to be embedded, and the vertical displacement of the battery pack on the plug-in seat can be limited by the plug-in strip and the long groove, and at the same time, the male plug in the plug-in slot can be embedded in the female slot on the plug-in end, thereby completing the power connection between the battery pack and the plug-in seat; wherein the positioning block on the upper surface of the plug-in end is embedded in the positioning groove, and the horizontal position of the battery pack on the plug-in seat can be limited by the positioning block and the positioning groove; finally, it is conducive to the stable plugging and fixing of the battery pack;

[0015] 2. Press the pressing part at the position of the second through hole downward with your fingers, so that the positioning block moves downward and then retracts into the first through hole, and the return spring is compressed, and then the plug-in end can be easily embedded in the plug-in slot; when the plug-in end is inserted into the plug-in slot, release the pressing part, and under the action of the elastic restoring force of the return spring, the return spring can push the positioning block upward, so that the positioning block is embedded in the positioning slot;

[0016] 3. The guiding bevel provided on one side of the positioning block close to the plug-in slot can play a guiding role. When the plug-in end is embedded in the plug-in slot, the guiding bevel contacts the side of the plug-in seat, so that the positioning block automatically retracts into the first through hole;

[0017] 4. The pressing part can be recessed for fingers to fit into, making it easier for fingers to apply force accurately;

[0018] 5. The anti-skid stripes provided on the inner wall of the concave portion can increase the friction force, thereby facilitating stable pressure application by the fingers;

[0019] 6. By using the first guide plate arranged on the inner wall of the cavity layer and the second guide plate arranged at the lower position of the pressing part away from the positioning block, the first guide plate and the second guide plate can play a guiding role, which is conducive to the stable up and down movement of the positioning block and the pressing part;

[0020] 7. Make sure that the distance between the outer edge of the blade and the motor is greater than the distance between the inner edge of the blade and the motor. At this time, the inclination angle of the blade can be increased; because the increase in the inclination angle can increase the contact area between the blade surface and the air, the blade can bring more air to form a larger airflow. When the inclination angle of the blade increases, the fan projection area of ​​the blade also increases, and the wind force generated is relatively large. BRIEF DESCRIPTION OF THE DRAWINGS
