An information collection device

Abstract

The invention discloses an information acquisition device. The information acquisition device comprises a base body with an accommodating cavity formed inside, and a first mounting cavity is formed in the inner top wall of the accommodating cavity; a second mounting cavity is formed in the inner bottom wall of the accommodating cavity; a transmission groove which extends to the right side is formed in the position, at the bottom of the second mounting cavity, in the base body; a through groove which extends upwards and penetrates through the base body is formed in the tail of an extension section on the right side of the transmission groove; a first sliding groove which extends upwards and stretches into the first mounting cavity is formed in the inner wall on the back side of the accommodating cavity; a first screw rod is arranged in the first sliding groove; the first screw rod is connected with a first driving machine; the first driving machine is arranged on the inner top wall of the first mounting cavity; the first driving machine is fixedly connected with the inner top wall of the first mounting cavity; a first sliding block which is in thread fit connection with the first screw rod and is in slide fit connection with the first sliding groove is arranged on the first screw rod; the front end face of the first sliding block stretches into the accommodating cavity; a top beam is fixedly arranged on the front end face of the first sliding block; and sliding plates are symmetrically arranged on the two sides of the top beam. According to the information acquisition device, the structure is simple, operation is convenient, the device can be adjusted according to the size of acquisition objects, the acquisition range is wide, efficiency is high, irradiation light can be prevented from leaking outwards, acquisition safety is improved, the case handling process is quickened, and conventional requirements are met.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an information collection device. Background technique [0002] Information collection technology is widely used in criminal investigation, and laser irradiation is an important method in the information collection process. It mainly uses laser light to irradiate the surface of the material, so that the criminal information (fingerprints, dander, hair, etc.) left on the surface of the material can be revealed. , It has a good display effect on glass, wood, plastic, textiles and metal bodies. It is difficult to extract information on large-sized substances. It has a wide range of irradiation and extraction, and the efficiency of manual irradiation and extraction by case investigators is low. Delaying the progress of case handling, and at the same time, in the process of irradiating and extracting, the irradiated light will cause great damage to the human body, and there are l...

[0002] Information collection technology is widely used in criminal investigation, and laser irradiation method is an important means in the process of information collection. It mainly uses laser to irradiate the surface of the material, so that the criminal information (fingerprints, dander, hair, etc.) left on the surface of the material can be revealed. , has a good effect on glass, wood, plastic, textiles and metal objects. It is difficult to extract information from larger materials in the existing technology. It has a wide range of irradiation and extraction, and the efficiency of manual irradiation by case handlers is low. Delay the progress of case handling, and at the same time, in the process of irradiating and extracting, the irradiating light will cause great damage to the human body, and there are major defects, so it is difficult to meet the needs of criminal investigation work
