Zusammenfassung: | The utility model discloses a finger -type coupling device, including equal open -ended pipe in upper and lower both ends and baffle, the equal open -ended pipe in both ends divide into upper segment and hypomere through the baffle from top to bottom, and the upper segment is colorless transparent, and the hypomere is dark opaque, be provided with the through -hole on the baffle, the utility model discloses finger -type coupling device adopts double -colored finger -type coupling, but make full use of trichogrammatid's phototaxis, and effective light -resistant makes trichogrammatid shift fast, the utility model discloses but finger -type coupling device is two finger -type pipes of quickmelt in the process of the test, and the upper segment and the hypomere of pipe respectively cup joint the finger -type pipe promptly, than current scheme save time, just the utility model discloses finger -type coupling device passes through the design of through -hole and guide panel because the through -hole is less, can b |
