The front end of the plate 42 abuts against the outlet end 31 of the feeding track 2, and the rear end of the baffle 42 abuts against the inner side of the feeding track 2 and is inclined. The inner side wall of the baffle 42 is located in the feeding channel of the feeding track 2. By setting the baffle 42 in an inclined state, the baffles 42 on the left and right sides are in an "eight" structure from the back to the front, forming a pressing area.
