Fault detection device under vpx framework composite bus condition

The invention belongs to the technical field of vpx frameworks and in particular relates to a fault detection device under a vpx framework composite bus condition. The fault detection device comprisesa bus analysis instrument and a sucking disc, a fixed cylinder is fixed on the outer wall of the bus analysis instrument, a vertical hole is formed in the upper end of the fixed cylinder, the lower end of an extrusion rod is connected with a cross rod, a vertical rod is mounted inside a vertical cylinder, the vertical rod is mounted inside a locating slot, a mounting rod is mounted inside a mounting slot, a supporting cylinder is mounted inside a base, a second working bearing is mounted at the lower end of a working beam, and the sucking disc is mounted at the lower end of the base. The fault detection device under the vpx framework composite bus condition designs a structure having a regulating function, so that the problem that a display position of the traditional device is inconvenient to adjust is solved; a
