Abstract
A telescopic limiting structure includes a first retractable member and a second retractable member. The first retractable member includes a first inclined face and is configured to move along a first direction. The second retractable member includes a second inclined face bearing against the first inclined face. The first inclined face and the second inclined face are configured to drive the second retractable member to move along a second direction in response to the first retractable member moving along the first direction. The second direction is different from the first direction. The first retractable member includes a first elastic element configured to extend and retract along the first direction, the second retractable member includes a second elastic element configured to extend and retract along the second direction, and in a process of compressing the first elastic element, the second elastic element moves closer to the first retractable member in the second direction.
