[0006] Furthermore, a limiting slide groove is provided at the lower inner side of the cavity, the lower part of the supporting bottom plate is provided as a semicircular structure, and the supporting bottom plate and the limiting slide groove are slidably connected.

[0007] Furthermore, an external air hole is opened on the outside of the cavity, and the external air hole passes through the cavity. An internal air hole is opened on the side of the supporting bottom plate, and the internal air hole is connected to the external air hole.

[0008] Furthermore, the lining is movably connected to the interior of the cavity, and the lining is made of elastic breathable material.

[0009] Furthermore, a connecting groove is provided on the inner side of the upper part of the cavity, a connecting spring with one end connected thereto is provided inside the connecting groove, a limiting clamp plate is connected to the other end of the connecting spring, and the limiting clamp plate and the lining are crimped to each other.

[0011] Furthermore, the prosthetic connecting member is a cylindrical structure, and the damper and the prosthetic connecting member have the same axis.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:

[0013] The flexible shock-absorbing prosthetic receiving cavity proposed in this scheme, by setting a supporting base plate in the cavity and connecting the supporting base plate to the cavity with a supporting spring and damping, can play a buffering role when the cavity causes impact to the residual limb, reduce the rigid force of the residual limb, protect the residual limb and increase comfort.
