The dog is now used to support the pion, Omega, alpha and tau.

摘要

The invention relates to a PW, Omega, and a D device.It is reported that the array contains elastic cover and plastic cover, and the neck and cap are located at the neck of the neck. I contains a neck clip.The center of the cap is provided with flange and the support edge is connected to the central flange. The shell is passed through at least one connection.According to the invention, the connecting shell is elastically deformed, thereby making the axial displacement a under the action of CT force. Support kappa from high to low (R) in the middle of the channel (I).Supports with stiffness K1 between the corresponding edges of the first deformation displacement amplitude The deformation displacement amplitude of a second shell with K2 stiffness is corresponding to the support and low of the middle position between the edges. Position.
