The usage of a flower hammer primarily includes the correct way to hold it, having a clear target, maintaining an appropriate distance, and adjusting the force to ensure the safe and effective use of the flower hammer.

Holding Method: When holding the flower hammer, keep a stable grip without exerting too much force to avoid hand fatigue. Generally, your fingers should be slightly apart, and it is best to hold the hammer handle in the middle. This position allows better control over the striking force.

Clear Target: Before using the flower hammer, identify your target. Clearly determine the object you want to strike or move and make necessary preparations before the actual operation.

Maintain Appropriate Distance: During the striking process, ensure you maintain an appropriate distance. Adjust your distance according to the object that needs to be struck, ensuring the force is moderate and avoiding excessive damage.

Additionally, although the maintenance and usage precautions of the flower hammer are not directly mentioned, insights can be drawn from the usage methods of other tools. Proper maintenance can reduce the likelihood of malfunctions and extend the tool's lifespan. This includes regularly checking and replacing worn parts, keeping it lubricated, and being mindful of the usage environment.

In summary, the correct usage of a flower hammer involves proper holding and operation techniques, adequate preparation and maintenance, ensuring both safety and efficiency.
