Acoustic emission fixing device for sleeve tensile test

The utility model provides an acoustic emission fixing device for a sleeve tensile test, which not only solves the problem that an adhesive tape is inconvenient to fix when the acoustic emission fixing device is used, but also enables a sensor to be tightly attached to the outer surface of a monitoring area all the time in an experiment process and to be convenient to disassemble, and adopts the technical scheme that the acoustic emission fixing device is characterized by comprising a bracket, the support is divided into a left support and a right support which are correspondingly arranged, cylinders are fixedly connected to the middle of the left support and the middle of the right support respectively, acoustic emission sensors are connected into the cylinders respectively, a plurality of connecting holes are formed in the upper ends and the lower ends of the left support and the right support respectively, and the corresponding connecting holes of the left support and the right support are detachably conne
