Abstract: A telescopic adjusting mechanism includes: an outer tube having a positioning unit; an inner tube having a hole and displaceable relative to the outer tube along a longitudinal axis; a locking unit displaceable along with the inner tube, and including a locking member movable along a transverse axis between a locking position, where the locking member extends through the hole to engage the positioning unit, and an unlocking position, where the locking member is disengaged from the positioning unit, and a biasing member biasing the locking member to the locking position, the locking unit being formed with an engaging member; a restraining member engaging releasably the engaging member when the locking member is at the unlocking position to prevent the locking unit from hindering retraction of the inner tube into the outer tube; and a drive unit operable to move the locking member from the locking position to the unlocking position.

Abstract translation: 伸缩调节机构包括：具有定位单元的外管; 内管，其具有孔，并且沿着纵向轴线相对于所述外管可移位; 锁定单元可与内管一起移动，并且包括可沿着横向轴线移动的锁定构件，其在锁定构件延伸穿过孔以接合定位单元的锁定位置和锁定构件脱离位置之间的解锁位置 以及偏置构件将所述锁定构件偏置到所述锁定位置，所述锁定单元形成有接合构件; 所述限制构件在所述锁定构件处于所述解锁位置时可释放地接合所述接合构件，以防止所述锁定单元阻碍所述内管进入所述外管的缩回; 以及驱动单元，其可操作以将所述锁定构件从所述锁定位置移动到所述解锁位置。
