[0030] Working principle:

[0031] When in use: the first step is to put the chicks into the annular screening plate 10, and the staff will screen the healthy chicks from the sick and weak chicks, and screen the sick and weak chicks and put them into the weak chick hopper box 11.

[0032] Place the healthy chicks inside the placement table 14, and after placing several healthy chicks one by one in several resistance grooves 31 by setting the resistance plate 30 to cooperate with the resistance groove 31 opened therein, push the top plate 20 in the direction of the resistance plate 30, and the top plate 20 drives the connecting plate 26 and makes the push plate 40 move in the direction of the resistance plate 30, and the push plate 40 drives the elastic band 44 to elastically position and press the healthy chicks located in the resistance groove 31, so that the healthy chicks can be quickly positioned inside the placement table 14.

[0033] In the second step, after positioning the healthy chick inside the groove 31, the pull ring 51 pulls the pull rope 58 outward, and the pull rope 58 drives the fixed slide 57 and causes the dye core rod 50 to move laterally inside the empty groove 32.
