According to the utility model, the knob is rotated, the knob drives the threaded rod to rotate in the threaded cylinder so as to control the extension and retraction of the transparent cover, the sliding block in the shell slides along the sliding chute of the transparent cover, the transparent cover can only slide, the limiting block of the transparent cover slides on the inner wall of the shell, excessive extension and retraction are prevented, the knob is reversely rotated, and carrying and storage are facilitated; and the lamp tube is protected from collision damage.

The invention discloses a law enforcement document generation method and device and electronic equipment. The method comprises the following steps: acquiring case information, and receiving an inquiry record which is uploaded by a law enforcement officer and corresponds to the case information; according to the case information, a law enforcement knowledge graph is retrieved, legal provisions and historical punishment cases corresponding to the case information are obtained, and the law enforcement knowledge graph is used for representing and reflecting entity relations, law and regulation changes and case states in the cultural law enforcement system; a law enforcement document corresponding to the case information is generated according to the inquiry records, the legal provisions and the historical punishment cases, and the law enforcement document at least comprises illegal facts, punishment reasons and punishment contents of the case information. The technical problems that in the cultural law enforcement field, law enforcement document writing consumes long time, laws and regulations and historical case knowledge are dispersed, and the workload of manual consultation is large are solved.

The application discloses an AI multi-modal law enforcement record document generation method, which obtains multi-modal original data such as audio stream, video stream, image and text of a law enforcement scene, respectively preprocesses each modal data to obtain each modal feature representation, inputs each modal feature representation into a multi-modal fusion model, aligns and fuses multi-source information through a cross-modal attention mechanism to obtain unified law enforcement event semantic representation, determines a law enforcement document type according to the law enforcement event semantic representation, combines a legal regulation knowledge graph and a large language model to automatically fill in document elements to generate a law enforcement document draft, and outputs a final law enforcement document through compliance verification.
