while winding the string, I also do some points.

the function of the clock hammer is as an energy storage device, so the clock can run for a relatively long time unattended. When winding the clock driven by the bell hammer, you can tighten the rope and lift the bell hammer. This will give the bell hammer potential energy under the action of the earth's gravity field. As you can see later, the clock uses the potential energy when the hammer falls to drive the mechanism to run.

To design the simplest clock by using the falling hammer-a clock with only the second hand, it is necessary to install the second hand on this simple clock, so that the normal second hand on any clock can work and rotate once every 6 seconds. In this simple mechanism, releasing the hammer will lead to rapid falling, and the drum will rotate at a speed of about 1rpm (revolutions per minute) until the hammer falls to the floor.

Extended information:

Precautions:

1. It should be hung on a dry wall to prevent moisture from entering the movement, resulting in short circuit of the circuit board and corrosion of electronic parts of the movement.

2. Don't open the back cover of the quartz clock movement at will, so as to avoid dust from entering the movement and adsorbing on the rotating parts, speeding up the wear of parts and reducing the service life.

3. Replace the battery regularly to prevent the corrosion of the movement caused by the decay of the battery case.

4. It should be hung indoors in the shade to avoid direct sunlight or radiation from other heat sources.
