Abstract
The invention relates to an integrative three-segment tripod. The tripod has a main bracket and at least one stand leg having an upper segment, a middle segment and a lower segment. The upper segment, the middle segment, and the lower segment are each telescopically connected together. The stand leg further includes a locking unit and a safety device. The locking unit fixes the middle segment to the upper segment and simultaneously fixes the lower segment to the middle segment. The safety device is associated with the locking unit and keeps the locking unit in the fixing state when the locking unit is in the locking position. Therefore, each stand leg of the tripod can be controlled easily by a single locking unit, and the safety device prevents the rotation lever from inadvertent release.
