Abstract

The invention discloses a fish measuring device. The device can adsorb a fish on a rotary disc, and the length, width, height and figure curve of the fish can be displayed on a drawing board with a grating measurement scale through equal proportion scaling when the device slides on a fish body, thereby obtaining all the data. The device comprises a sorption pump, the rotary disc and a support. The rotary disc is provided with multiple rotary disc holes. Each rotary disc hole is internally provided with an air suction pipe. Each air suction pipe is connected with a gas-guide pipe, and the other end of each gas-guide pipe is connected to the sorption pump. The rotary disc is horizontally connected on the support in a rotatable manner. The support is provided with a rear vertical drawing board with a grating scale. The support is provided with a longitudinal slide rail. The longitudinal slide rail is provided with a vertical slide rail. The vertical slide rail is connected with a horizontal slide rail. The horizontal slide rail is provided with a vertical rod. A lower end of the vertical rod is provided with a ball. The vertical rod is slidably provided with a longitudinal rod, and an end part of the longitudinal rod is provided with a paintbrush. The invention is mainly applied to fish measuring technologies.

Description

technical field [0001] The invention relates to the technical field of fish measurement, in particular to a fish measurement device. Background technique [0002] At present, there is no device specifically for measuring the shape of fish. The length, width, and height reflecting the size of the fish and the curve reflecting the shape of the fish are the data that must be collected to study the fish. Therefore, it is very necessary to design a fish measuring device that can easily obtain the length, width, height and various data of the fish profile curve. Contents of the invention [0003] The present invention provides a fish measuring device for conveniently obtaining the data of the length, width, height and shape curve of the fish. The method converts the length, width, height and shape curve of the fish in proportion to the drawing board with the grid measurement scale, so as to obtain more accurate data of the length, width, height and shape curve of the fish. ...
