Detector convenient to quickly store and carry

The detector comprises a detector body, a connecting support and two connecting blocks, the connecting support is located at the bottom of the detector body, the two connecting blocks are located on the left side and the right side of the bottom of the detector body respectively, and the left side and the right side of the connecting support are both in contact with the surfaces of the connecting blocks. A containing groove is formed in an inner cavity of the connecting support. Through the cooperative use of the detector, the connecting bracket, the connecting block, the placing groove, the positioning mechanism and the transmission mechanism, the problem that a plurality of threaded components are assembled and fixed with the connecting bracket during the installation of the existing detector, so that the detector is inconvenient to carry when the detector needs to be carried out for detection is solved. The problem that the convenience of the detector is reduced due to the fact that a plurality of thread a
