The presence of the buffer gap 2300 provides a sufficient deformation space for the deformation of the first connection block 231, thereby improving the damping capability for vibrations from the X-axis direction and enhancing the shock absorbing effect.

Alternatively, the first connection block 231 is disposed along the length direction of the shock-absorbing frame 20, and the second connection block 232 is disposed along the Y-axis direction. The first connection block 231 and the second connection block 232 are perpendicular to each other, which is beneficial to improving the shock absorbing capacity in the Y-axis and X-axis directions.

Optionally, the second connection block 232 is a hollow cylinder. The first connection block 231, the second connection block 232 and the two third connection blocks 233 are integrally formed, so that the stability of the buffer member is improved.

The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
