The utility model discloses a device for measuring the thickness of a reinforced concrete protective layer before pouring, which comprises a handheld telescopic rod, a fixed clamping piece and a displacement sensor, one end of the displacement sensor is connected with the fixed clamping piece, and the other end of the displacement sensor is in point contact with the surface of an externally placed protective layer template; the position where the displacement sensor is connected with the fixed clamping piece is electrically connected with an external digital display instrument through an external cable. The handheld telescopic rod is perpendicular to the displacement sensor and is assembled on the upper end face of the fixed clamping piece. The end faces of the two sides, parallel to the assembling position of the displacement sensor, of the fixed clamping piece extend outwards to be provided with triangular prisms, and the triangular prism on the side away from the displacement sensor is in point contact wit
