Acoustic emission probe fixing device for hydraulic fracturing test and use method

The invention relates to the technical field of indoor hydraulic fracturing tests, in particular to an acoustic emission probe fixing device for a hydraulic fracturing test and a using method. In order to solve the problems that an existing acoustic emission probe is fixed to a designated position through an adhesive tape, operation is inconvenient, two persons need to work cooperatively, positioning is not accurate, meanwhile, the probe is prone to falling off, and signal capture is affected, the following technical scheme is provided that a fixing device comprises a bandage and a probe fixing mechanism, and the bandage is provided with a plurality of mounting holes; a second fixing column is mounted on one side of the probe fixing mechanism, the probe fixing mechanism comprises a mounting box, a circular groove is formed in the mounting box, and an open groove is formed in one side of the circular groove. The device is easy to install, high in adaptability, suitable for being connected with test pieces in d
