Pull type base device

The invention discloses a pull-type base device, and aims to solve the problem that the height of a pull-type base is inconvenient to adjust, so that the pull-type base is inconvenient to move and transport in the prior art. A base lower seat; each stand column is provided with a first connecting end hinged to the upper base and a second connecting end hinged to the lower base; the first limiting assembly and the second limiting assembly are configured to limit rotation of the hinged position of the second connecting end. When the stand column rotates to a first state around the hinged position of the second connecting end, the stand column is connected with the lower base through the first limiting assembly. When the stand column rotates around the hinged position of the second connecting end to a second state, the stand column and/or the upper base are/is connected with the lower base through a second limiting assembly. The pull type base can be switched between a working state and a moving state, so that t
