Wire row support detection device

The invention discloses a wire row support detection device which comprises a pressing plate and a bearing plate, and an inkpad layer corresponding to a support body of a to-be-detected wire row support up and down is laid on the bearing plate. A positioning structure capable of locating the support body on the bearing plate and reserving a gap between the support body and the inkpad layer is arranged between the support body and the bearing plate, a plurality of receding grooves corresponding to the lower bent parts in all rows are further formed in the bearing plate, and a plurality of protruding blocks are formed at the bottom of the pressing plate; a receding space is formed in the area, except the protruding blocks, of the bottom of the pressing plate, the receding space can make the pressing plate located on the support body prevent the pressing plate from pressing the support body to be damaged after the pressing plate is pressed downwards, and pressing action parts which can correspond to the rows of
