The utility model discloses a distance detecting means of non -contact RF chips class product reading and writing, it contains: but fixed platform, longitudinal support board, horizontal backup pad and lift platform. The last product that remains the measuring that sets up of fixed platform. Longitudinal support board one end sets up perpendicularly in an edge on fixed platform surface. Horizontal backup pad is fixed in the other end of longitudinal support board, and has the opening in the horizontal backup pad. But lift platform is located fixed platform top, but lift platform be used for fixed read write line and make the read write line reciprocate, make read write line test face down, can be in the upper surface laminating of extreme lower position with fixed platform. Therefore, the utility model discloses a distance detecting means of non -contact RF chips class product reading and writing, operation personnel easy operation, and it is efficient, can be through the simple accurate reading and writing distance of verifying the product that repeats to preparation low cost.
