First dipperstick 1 sets up with second dipperstick 2 is perpendicular, the bottom surface coplane, and inner laminating and welded fastening make whole measurement model be L shape structure.

The first measuring scale 1 is designed into two sections with different thicknesses along the length direction, and the two sections are respectively an outer section 101 and an inner section 102 of the first measuring scale, as shown in fig. 2, wherein the outer section 101 of the first measuring scale is designed into a thickness of 0.5mm, and the length of the outer section is designed into a length of 50mm, so that the outer section is used for measuring a gap of a characteristic 0.5mm characteristic value required by a standard. The first measuring ruler inner section 102 is designed to be 1.0mm thick and 100mm long for measuring the gap which is required by the standard and is characterized by the characteristic value of 1.0 mm.

The second measuring ruler 2 is also designed into two sections with different thicknesses along the length direction, namely, an outer section 201 of the second measuring ruler and an inner section 202 of the second measuring ruler, as shown in fig. 3; the thickness of the second measuring scale outer section 201 is designed to be 0.1mm, the length is designed to be 50mm, and the second measuring scale outer section is used for measuring a gap which is required by a standard and represents a characteristic value of 0.1 mm. The second measuring ruler inner section 202 is designed to be 1.0mm thick and 100mm long, and is also used for measuring the gap which is required by the standard and is characterized by the characteristic value of 1.0 mm.

A grab handle 3 is fixed at the connecting position; the handle is provided with a vertical connecting section 301 and a horizontal holding section 302 and is arranged on the top surface of the measuring template. Wherein vertical linkage segment 301 is the cylinder structure, and bottom welded fastening is in first dipperstick 1 and the inner department of meeting in second dipperstick 2. The section 302 is gripped to the level is the cylinder structure simultaneously, transversely sets up, and welded fastening between central point puts and the 301 tops of vertical linkage segment, and above-mentioned level grip section 302 axis sets up to be 45 degrees with two dipperstick long limits, makes the level grip section 302 both ends respectively towards first dipperstick 1 and second dipperstick 2 one side, is convenient for grip the measurement model when measuring and impels two dippersticks respectively in the gap.

Because the thickness of the first measuring section outer section 101 and the second measuring section outer section 201 is small and is not easy to distinguish visually, the outer section thickness value of the measuring scale towards which the end part faces is engraved on the end faces of the two ends of the horizontal holding section 302 due to the angle design between the horizontal holding section 302 and the two measuring scales.
