Fixing device for detection of vehicle seats

The utility model discloses a fixing device for detection of vehicle seats. The fixing device comprises a first fixing unit and a second fixing unit; the first fixing unit and the second fixing unit are disposed on the left and right of a detection bench; the first and second fixing units comprise clamping portions used for clamping and fixing two slide rails arranged at the bottom of a seat; after fixation, the length-wise direction of the slide rails is perpendicular to the spacing direction of the first and second fixing units; spacing of the first and second fixing units is adjustable. Changes in the sizes of the slide rails of different types of seats are small, so that the seat is fixed through the first and second fixing units which are arranged on the left and right and which are used for clamping and fixing the slide rails at the bottom of the seat; the requirement for a plurality of fixing lock sets used to fix slide legs in the traditional technical scheme is avoided, and cost of seat detection equ
