Preferably, a plurality of scales are arranged on the inclined edge of the triangular block, so that the measurement accuracy of the ruler is improved.

Preferably, the degree of triangle piece bottom acute angle is adjustable, increases the acute angle degree, can stretch the length of triangle piece hypotenuse, makes the scale interval increase, and the reading is more clear, reduces reading error and avoids reading the mistake.

Preferably, the limiting claw comprises an L-shaped sliding rod, a clamping block and an auxiliary pressing block, the L-shaped sliding rod is a transparent cylinder, the clamping block can be clamped at the bottom of the L-shaped sliding rod and slides in the sliding groove, and the auxiliary pressing block is in the shape of a right triangle and can freely rotate in the direction perpendicular to the length direction of the L-shaped sliding rod.

Preferably, the L-shaped sliding rod can stretch and retract to adapt to clamping of objects to be measured with different thicknesses, and the measuring range is expanded.

The utility model has the advantages that: the utility model provides a pair of cockscomb structure ruler can measure the size of various irregular objects to number and the synthetic numerical value of scale value and the scale value on ruler body surface on the triangle briquetting check each other between the two, thereby accurately obtain the size of testee, reduce reading error and avoid the reading mistake. The utility model discloses a set up the angle of more scales and increase bottom acute angles on the triangle block hypotenuse, thereby further promoted the utility model discloses a measurement accuracy and reading accuracy have expanded measuring scope through setting up the spacing claw that can stretch out and draw back.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention is described in detail below with reference to the accompanying drawings and examples.

As shown in fig. 1-3, the utility model discloses a technical scheme a cockscomb structure ruler mainly includes ruler body 1, spout 2, ruler body scale 3, triangle briquetting 4 and spacing claw 5, and its characterized in that ruler body 1 top has the groove that holds triangle briquetting 4, and spacing claw 5 can impress triangle briquetting 4 the inslot perpendicularly. The triangular pressing block 4 comprises a triangular block 41, a spring 42, a triangular pressing block scale 43 and a triangular pressing block number 44, the triangular block 41 is a right-angle triangular block, the spring 42 can bounce the triangular block 41, the triangular pressing block scale 43 is consistent with the ruler body scale 3 in the horizontal direction, and the triangular pressing block number 44 is consistent with the ruler body 1 main body scale. The limiting claw 5 comprises an L-shaped sliding rod 51, a clamping block 52 and an auxiliary pressing block 53, the L-shaped sliding rod 51 is a transparent cylinder, the clamping block 52 can be clamped at the bottom of the L-shaped sliding rod 51 and slides in the sliding groove 2, and the auxiliary pressing block 53 is in a right triangle shape and can freely rotate perpendicular to the length direction of the L-shaped sliding rod 51.

More scales are arranged on the oblique side of the triangular block 41, so that the measuring accuracy of the ruler can be improved. The degree of the sharp angle in 41 bottoms of increase triangle piece can stretch the length of triangle piece hypotenuse, makes the scale interval increase, and the reading is more clear, reduces reading error and avoids reading error. The telescopic L-shaped sliding rod 51 can be clamped with objects to be measured with different thicknesses, and the measuring range is expanded.

Fig. 4 shows a first embodiment of the invention. When an object with a regular shape is measured, firstly, one limiting claw 5 of the ruler is arranged at the starting point of the scale 3 of the ruler body and is flush with one side of the measured object, then the ruler is pressed on the surface of the measured object, and the other limiting claw 5 is slid to the other side of the measured object, so that reading can be started. The scale value reading method comprises a triangle pressing block scale value 43, a number on the triangle pressing block and a scale value on the surface of the ruler body 1, wherein the combination reading value of the triangle pressing block scale value 43 and the triangle pressing block number 44 is consistent with the scale value on the surface of the ruler body 1, and the two data can be checked with each other, so that the reading error is reduced and the reading error is avoided. According to the number of the triangular pressing blocks 4 pressed into the grooves, approximate values can be quickly read.
