Where is the internal structure spring of the clockwork toy installed?

You can usually see it on the side of the toy. First, install the spring into the C-shaped retaining ring (the outer diameter of the C-shaped retaining ring is smaller than the installation space). Install the installed C-buckle and spring into the clock. Take out the c key with a clip or fine print.

Clock springs are also called springs with spiral lines in one plane. A spring is a kind of spring that winds a material into a plane spiral. One end of the spring is fixed, and after the other end acts torque, the material is subjected to bending moment, which produces bending elastic deformation, so the spring produces torsion in its own plane.

Its deformation angle is proportional to the torque, and it has higher torque, which is different from multi-angle torque. Therefore, it is not easy to fatigue when used in a mechanism that works for a long time, and its application is similar to that of a torsion spring.
