Abstract

The invention belongs to the field of questionnaires, and particularly relates to a mechanism for a questionnaire survey in a public place. The mechanism comprises a base, four uniformly distributed supporting legs are fixedly connected to the outside of the base, a threaded rod is connected to the interior of each supporting leg through a thread, a ring groove is formed in each threaded rod, connecting blocks are slidably connected to the inner sides of the supporting legs, rolling wheels are arranged at the bottoms of the connecting blocks, connecting bases are fixedly connected to the tops of the connecting blocks, threaded rods are rotatably connected to the interiors of the connecting bases, a connecting shell is fixedly connected to the top of the base, and the top of the connecting shell makes contact with a placing frame. According to the mechanism, through the design of the supporting legs, the threaded rods, rotary knobs, the connecting bases, the connecting blocks, annular grooves, the rolling wheels and other components, the whole body has mobility; and the rolling wheels are stored in the supporting legs through the operation of rotating the rotary knobs and the like, the supporting legs make contact with the ground, and the whole body can conveniently stand on the ground and is prevented from sliding.
