Detection support convenient to disassemble and assemble

The utility model relates to the field of detection supports, and discloses a detection support convenient to disassemble and assemble, which comprises a first bottom plate and a second bottom plate, and two sides of the middle part of the upper surface of the first bottom plate are respectively provided with two chutes. According to the support for air detection, a rotating handle is rotated to enable a driving gear to drive a driven gear to rotate, meanwhile, the driven gear drives an adjusting threaded rod to rotate, a second threaded sleeve ascends to drive a movable rod to ascend, and meanwhile, a second bottom plate ascends to drive a first bottom plate to ascend; according to the air detection instrument, the main rod is matched with the tripod surrounding the main rod, so that a worker can detect air environments at multiple heights in the air detection process, and the flexibility and the accuracy of the air detection instrument in the working process are improved; the safety and the stability of the
