Abstract

A scaffold with macro and micro adjust function comprises a screw, a bracing device smocks the screw, an adjusting device set on the screw and connected with the bracing device to adjust the height, also, a hole structure is includes in it. The hole structure smocks screw and include upper and lower U-shaped wall set on the upper side and the lower side of the hole structure. The first screw thread and second screw thread are set respectively on the upper side and lower side U-shaped wall. The adjusting device can slope some angle in order to make the upper and lower U-shaped wall to separate from the screw. The adjusting device can go up and down through turning the screw or slip along the screw when the upper and lower U-shaped wall getting close to or depart the screw.

Description

technical field [0001] The invention relates to an adjustable tripod, in particular to a tripod with functions of coarse adjustment and fine adjustment. Background technique [0002] In general projectors and other related products, height-adjustable tripods are often used to adjust the elevation or height of the projector, so as to project images onto the curtain or wall smoothly. Therefore, how to design a tripod that can easily adjust the height of the support has become an important issue for designers. [0003] see figure 1 , figure 1 It is a structural schematic diagram of the existing projector stand 10 . The projector stand 10 is used to support a projector 12 . Such as figure 1 The conventional projector stand 10 shown includes a screw 14 and a lifting element 16 for supporting the projector 12 . The lifting element 16 includes a screw hole 18 . The lifting element 16 is sleeved on the screw rod 14 through the screw hole 18 . When the user wants to adjust th...
