Device for measuring encircling force of frog fore limbs

Abstract

The invention discloses a device for measuring encircling force of frog fore limbs. The device comprises a pedestal; a round rod is mounted at the top end of the pedestal; a bending plate is arrangedon the outer wall of the round rod; a top rod is mounted on the inner wall of the bending plate; the top rod penetrates through one part of the round rod; a second inner cavity is formed in the roundrod. According to the device for measuring the encircling force of the frog fore limbs and through moving cooperation between a centimeter ruler mounted on the round rod and the bending plate on the round rod, the encircling force of the frog fore limbs is effectively detected; meanwhile, the moving distance of the bending plate is checked effectively through the centimeter ruler, so that the sizeof the encircling force of the frog fore limbs can be calculated conveniently; the fore limbs of the frog are put at the joint of a round block and a clamping ring, so that the clamping ring and a bayonet on a soft block are superposed and the fore limbs of the frog can be fixed effectively and conveniently; furthermore, the fore limbs are exerted under the condition of simulating the frog, so that the use efficiency and the practicability of the measuring device are improved and the use requirements of users are met.

Description

technical field [0001] The invention relates to the technical field of a measuring device for the embracing force of the forelimbs of frogs, in particular to a measuring device for the embracing force of the forelimbs of frogs. Background technique [0002] Anura is an animal belonging to the amphibian class. Adults are basically tailless. Eggs are generally laid in water, hatched into tadpoles, and breathe with gills. After metamorphosis, adults mainly breathe with lungs, but most of the skin also has part of the breathing function, mainly including two types of animals , frogs and toads, there is no strict difference between these two types of animals, and some families include two types at the same time. The forelimbs are fixed, which causes the frogs to move around when the frogs are detected, which affects the measurement effect. At the same time, it cannot meet the detection and encircling force of the frogs' forelimbs, which affects the use efficiency and practicabili...

After metamorphosis, adults mainly breathe with lungs, but most of the skin also has part of the breathing function, mainly including two types of animals , frogs and toads, there is no strict difference between these two types of animals, and some families include two types at the same time. The forelimbs are fixed, which causes the frogs to move around when the frogs are detected, which affects the measurement effect. At the same time, it cannot meet the detection and encircling force of the frogs' forelimbs, which affects the use efficiency and practicability of the measuring device. Less than the needs of users
