Clamping part structure and ceiling module

Provided are a clamping part structure and a ceiling module. The invention discloses the clamping part structure which comprises a limiting plate, an upper clamping part connected to the upper portion of the limiting plate and a lower clamping part connected to the lower portion of the limiting plate. The upper clamping part comprises a first limiting part connected to the limiting plate and a first clamping part, the first limiting part surrounds the first clamping part, the first clamping part extends in the direction far away the limiting plate from the limiting plate and is protruding out of the first limiting part, at least two clamping arms are oppositely arranged on the first clamping part in the circumferential direction of the first clamping part, the lower clamping part comprises at least two reversely arranged clamping barbs, and hook heads of the clamping barbs are in the direction far away from the limiting plate. Therefore, a ceiling buckling plate can be installed on an auxiliary keel quickly, is small in installing difficulty and convenient to install, deformation of the ceiling buckling plate is avoided, and installing quality of the ceiling buckling plate is improved.
