Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Implementation of the present invention: a perimeter measuring ruler, comprising a jaw 1, jaws 2 and feet 3, the jaws 1, jaws 2 and feet 3 are connected by a shaft 4, the jaws 1 It consists of two hooked claws 11, and a wire 10 is threaded through one of the hooked claws. One end of the wire 10 is connected to the claw head of the other hooked claw. The scale 5 that the shaft 4 rotates, the other end of the scale 5 is connected with a square box 6, the box 6 is provided with a shaft 8, a clockwork spring 7 is arranged on the shaft 8, and the other end of the line 10 passes through Over scale 5 is connected with the outer layer reed on the clockwork spring 7 .

[0032] The scale 5 is a hollow structure.

[0033] A stop plate 12 is provided at the 0 mark of the scale 5 .

[0034] A pointer 13 is arranged on the line 10 in the scale 5 a...

Abstract

The invention discloses a perimeter measuring scale and a measuring method thereof. A jaw is composed of two hook-shaped claws. A wire passes through a hook-shaped claw. One end of the wire is connected with the head of other hook-shaped claw. A jaw shaft is connected with a calibrated scale capable of rotating about the jaw shaft. The other end of the jaw shaft is provided with a square box in which a shaft is disposed. The perimeter measuring scale has simple structure and ingenious design, can be used for irregular cylinders, is small and light, can be operated by a single hand, may read out measurement results immediately, reduces the operator's labor burden, and improves labor efficiency. A field experiment production yield project no longer avoids the original relatively-difficult perimeter measurement of an irregular stem. The length of a flexible wire around the stem is the perimeter of the stem and is the moving distance of a pointer within the calibrated scale, and the moving distance can be immediately read out.

Description

technical field [0001] The invention relates to a perimeter measuring ruler and a measuring method thereof, belonging to the technical field of measuring rulers. Background technique [0002] Field yield measurement is an important part of field experiments for agricultural students. Field production measurement includes many measurement items. In the case of large samples, the mental and physical strength of the production measurement personnel will be seriously exhausted. For each production test project, even a little bit of technical improvement will bring considerable efficiency improvements. [0003] In field yield measurement, a common item is to measure the diameter of the stem. At this time, the operator generally uses a vernier caliper to measure. For example, for corn stalks, it is necessary to measure the diameter of the part of the stalk near the ground, but the corn stalk—including the part near the ground—is not a regular cylinder, and sometimes there is ev...
