Free end 16 contacts with the surface of the close base portion 11 of float portion 13, and the angle of elastic arm 15 and float portion 13 be acute angle or
Person obtuse angle.The position that free end contacts with float portion from elastic joint part more away from, then the arm of force of elastic force is longer, so less
Elastic force can just upspring float portion, i.e. rotating fulcrum；Conversely, the position that contacts from elastic joint part more close to, then elastic force
The arm of force is shorter, so needs larger elastic force that just float portion can be upspring.Preferably, the position for contacting connects away from elasticity
Socket part.
When the float portion 13 of shell fragment by external force when being depressed, float portion 13 occurs centered on elastic joint part 12
Deflection.Because the angle of elastic arm 15 and float portion 13 is acute angle or obtuse angle, therefore free end 16 can be along under float portion 13
Slide on surface.Because elastic arm 15 deviates initial position, therefore produce elastic deformation.The elastic deformation produces elastic force, and elastic force is with inclined
Off normal shifting increase and increase.The elastic force is acted in float portion 13, makes the trend that initial position is returned back to float portion 13.
When the external force that shell fragment is subject to is eliminated, the resilience of elastic arm 15 is so that float portion 13 returns back to initial position.Certainly, generally,
