The baffles are fixedly connected between the foraging channels, and an induction food disc is arranged in the center of the labyrinth body. The applicable object range of the experimental animals is wide, the labyrinth is not affected by the physiques, the sizes and other factors of the experimental animals, preciseness of experimental data is guaranteed, and the experimental efficiency is high.

The invention provides a cantilever beam type measuring device of crawling attaching force of insects or small animals and a method thereof. The measuring device comprises a cantilever beam holder, a strain foil force measuring unit, a sample platform, an xy-axis moving mechanism, a z-axis moving mechanism and a charge coupled device (CCD) imaging system. The method includes tying an insect through a pull thread to one end of the cantilever beam; observing position of the insect and pull force of the insect to the cantilever beam when the insect crawling, conducting overlooking shooting to obtain the projection distance between the insect and a holding hole at the top end of the cantilever beam; conduct side-looking shooting to obtain the vertical distance z between the insect and the holding hole; enabling 4 strain foils in the z-axis direction and 4 strain foils in the y-axis direction to be sequentially symmetrically distributed in double-section alternating mode at the root portion of the cantilever beam and form two bridge circuits and respectively measuring component force of the insect in the vertical downward direction and the horizontal direction. Therefore, the crawling attaching force when the insect crawls or the sample platform descends can be obtained. The device is small in interference and accurate in measurement due to independent action of the insect, thereby being suitable for measurement of the crawling attaching force of the insect.
