Abstract

A cushioning member includes a support portion, a first latch portion, a second latch portion, a first connection portion, a second connection portion, a first guide portion and a second guide portion. The first guide portion, the first latch portion, and the first connection portion are arranged opposite to the second connection portion, the second latch portion and the second guide portion on basis of the support portion as a center. When the first and second latch portions are in a relaxed state, a width of the support portion in a direction perpendicular to the axial direction is greater than a width of the first latch portion and a width of the second latch portion in the direction.

8 . The detachable device as claimed in claim 7 , wherein the first part further comprises a first accommodating cavity, the second part further comprises a second accommodating cavity, the first accommodating cavity communicates with the first position-limiting channel in the axial direction to accommodate the first latch portion in the relaxed state, and the second accommodating cavity communicates with the second position-limiting channel in the axial direction to accommodate the second latch portion in the relaxed state.

9 . The detachable device as claimed in claim 6 , wherein a length of the first connection portion in the axial direction is greater than or equal to a thickness of the first position-limiting channel in the axial direction, and a length of the second connection portion in the axial direction is equal to a thickness of the second position-limiting channel in the axial direction.

10 . The detachable device as claimed in claim 6 , wherein the first part further comprises a first disassembly channel, the first position-limiting channel communicates with the first disassembly channel in a second direction perpendicular to the axial direction, a width of the first position-limiting channel is greater than a width of the first disassembly channel in the first direction, the second part further comprises a second disassembly channel, the second position-limiting channel communicates with the second disassembly channel in the second direction perpendicular to the axial direction, and a width of the second position-limiting channel is greater than a width of the second disassembly channel in the first direction.

11 . The detachable device as claimed in claim 10 , wherein when the first connection portion and the second connection portion are in the relaxed state, the width of the first connection portion in the first direction and the width of the second connection portion in the first direction are respectively greater than the width of the first disassembly channel and the width of the second disassembly channel, and when the first connection portion and the second connection portion are in a compressed state, the width of the first connection portion in the first direction and the width of the second connection portion in the first direction are respectively less than the width of the first disassembly channel and the width of the second disassembly channel.
