Abstract
An elevating device with a latching function including a supporting rack, a supporting seat, a constant force spring and a latching member. The supporting seat moves longitudinally with respect to the supporting rack, and has a shaft rod automatically recovering towards a central line thereof. An arrow-shaped positioning block is installed in a front end of the latching member, a positioning concave slot is formed at bottom ends of a first and a second guiding planes of the positioning block. When the shaft rod moves with the supporting seat in the supporting rack, the shaft rod moves downwardly along the first guiding plane to enter the positioning concave slot forming a latching status. When the shaft rod moves downwardly in the positioning concave slot, the shaft rod is released from the positioning concave slot forming a releasing status, and the shaft rod moves upwardly along the second guiding plane.
