A fixture for insect testing

Abstract

The invention provides a fixing device based on an insect test, including a base, a pressing rod and a placement plate; it is characterized in that: the upper end surface of the middle support frame outside the base is provided with a threaded hole, and the fixing adjustment bolt passes through the thread The hole is fixed with the ball; the left end of the pressure rod is connected with the hole provided by the ball, and its right end is connected with the fixed rod on the outside of the support seat through a leather sleeve, and the left and right sides of the pressure rod are installed with the adjustment pressure of the passing rod body. block; the placement plate is placed on the ring bracket formed by the base and the support seat, and the end surface of the placement plate is located below the pressure bar, and the circular arc surface in the middle of the pressure bar and the brushes on both sides are used to treat various types of insects. Fix the body and wings of the insect test body to avoid damage to the insect test body, and this appliance is small and exquisite, easy to clean the placement plate, and the bottom is a hollow base in the middle, which is good for insects placed under a magnifying glass, microscope and dissecting mirror. effect.

Description

technical field [0001] The invention belongs to the technical field of test appliances, and more specifically relates to a fixing appliance for insect experiments. Background technique [0002] Insect experiments are an important means to understand the external morphology of insects, internal anatomy and physiology of insects, insect biology, insect taxonomy, insect ecology and entomological experiments. For theoretical teaching, it discusses the diversity of insects and the relationship between insects and humans in detail. The morphological structure and corresponding biological functions of insects, the growth, development, metamorphosis and reproduction of insects, the principles and methods of insect classification and the classification from orders to families play an important role. [0003] Based on the above: the designer found that the existing insect test fixtures have certain shortcomings. The fixation method is single and cannot flexibly fix different types and...
