The hollow outer section includes a first sidewall, a second sidewall and a third sidewall. The hollow inner section includes a fourth sidewall, a fifth sidewall and a sixth sidewall. A pair of sliding rails is disposed on the interior side of the first sidewall and a pair of raised sliding grooves is defined on the exterior side of the fourth sidewall. The pair of raised sliding grooves engages with the pair of sliding rails to enable a sliding movement of the hollow inner section relative to the hollow outer section. ## Claims ### Claim 1 A telescoping structure, comprising: a hollow outer section comprising a first sidewall and a pair of sliding rails arranged on an interior surface of the first sidewall; and a hollow inner section slidably mounted in the hollow outer section, the hollow inner section comprising a fourth sidewall and a pair of raised sliding grooves arranged on an exterior surface of the fourth sidewall; wherein the pair of sliding rails are engaged in the pair of raised sliding grooves thereby enabling a sliding movement of the hollow inner section relative to the hollow outer section, so that the hollow inner section is movable between a retracted position, in which the hollow inner section is substantially inserted in the hollow outer section, and an extended position, in which the hollow inner section projects outwards from the hollow outer section. ### Claim 2 (depends on 1) The telescoping structure of claim 1, wherein the hollow outer section further comprises a second sidewall and a third sidewall, the second sidewall defines a first guiding groove, and the third sidewall defines a second guiding groove. ### Claim 3 (depends on 2) The telescoping structure of claim 2, wherein the hollow inner section further comprises a fifth sidewall, a sixth sidewall, a first cam follower arranged on an exterior surface of the fifth sidewall, and a second cam follower arranged on an exterior surface of the sixth sidewall. ### Claim 4 (depends on 3) The telescoping structure of claim 3, wherein the first cam follower is received in the first guiding groove, and the second cam follower is received in the second guiding groove. ### Claim 5 (depends on 4) The telescoping structure of claim 4, wherein the hollow outer section is a hollow straight prism having two openings. ### Claim 6 (depends on 5) The telescoping structure of claim 5, wherein the hollow outer section is a regular hexagonal prism. ### Claim 7 (depends on 6) The telescoping structure of claim 6, wherein each of the first sidewall, the second sidewall and the third sidewall is not adjacent to one another. ### Claim 8 (depends on 7) The telescoping structure of claim 7, wherein the hollow inner section is a hollow straight prism having two openings. ### Claim 9 (depends on 8) The telescoping structure of claim 8, wherein the hollow inner section is a regular hexagonal prism. ### Claim 10 (depends on 9) The telescoping structure of claim 9, wherein each of the fourth sidewall, the fifth sidewall and the sixth sidewall is not adjacent to on another. ### Claim 11 A telescoping structure, comprising: a hollow outer section comprising a first sidewall, a second sidewall, and a third sidewall, and a pair of sliding rails arranged on an interior surface of the first sidewall, the second sidewall defining a first guiding groove, the third sidewall defining a second guiding groove; and a hollow inner section slidably mounted in the hollow outer section, the hollow inner section comprising a fourth sidewall, a fifth sidewall, and a sixth sidewall, a pair of raised grooves arranged on an exterior surface of the fourth sidewall, a first cam follower arranged on an exterior surface of the fifth sidewall, and a second cam follower arranged on an exterior surface of the sixth sidewall; wherein the pair of sliding rails are engaged in the pair of raised grooves, the first cam follower is received in the first guiding groove, the second cam follower is received in the second guiding groove, so that the hollow inner section is movable between a retracted position, in which the hollow inner section is substantially inserted in the hollow outer section, and an extended position, in which the hollow inner section projects outwards from the hollow outer section. ### Claim 12 (depends on 11) The telescoping structure of claim 11, wherein the hollow outer section is a regular hexagonal prism having six sidewalls. ### Claim 13 (depends on 12) The telescoping structure of claim 12, wherein the hollow outer section further comprises a plurality of ribs interconnecting the six sidewalls to form the regular hexagonal prism. ### Claim 14 (depends on 13) The telescoping structure of claim 13, wherein each of the plurality of ribs spans and interconnects three of the six sidewalls. ### Claim 15 (depends on 14) The telescoping structure of claim 14, wherein the hollow outer section further comprises a top blocking member at a top opening of the hollow outer section, and the top blocking member is adapted to prevent the hollow inner section from moving out of the top opening of the hollow outer section. ### Claim 16 (depends on 15) The telescoping structure of claim 15, wherein the top blocking member is a rectangular metal plate. ### Claim 17 (depends on 16) The telescoping structure of claim 16, wherein a first edge of the top blocking member is mounted to the hollow outer section, a second edge of the top blocking member extends towards a central axis of the hollow outer section, and the second edge is opposite to the first edge. ### Claim 18 (depends on 17) The telescoping structure of claim 17, wherein the hollow outer section further comprises a bottom blocking member at a bottom opening of the hollow outer section, and the bottom blocking member is adapted to prevent the hollow inner section from disengaging from the hollow outer section through the bottom opening. ### Claim 19 (depends on 18) The telescoping structure of claim 18, wherein the bottom blocking member comprises a mounting portion mounted to the hollow outer section and an elastic portion protruding upwards from a top surface of the mounting portion, and the elastic portion is adapted to cushion the strike effect when the first hollow inner section projects from the hollow outer section. ### Claim 20 (depends on 19) The telescoping structure of claim 19, wherein the elastic portion is made of elastic plastic material.
