EMBODIMENTS

[0014] The invention is further explained in combination with all the drawings below. The preferred embodiment of the invention is as follows: according to FIG. 1 to FIG. 6, the adjustable bird feeding opening control system in the embodiment comprises an adjusting ring 1, sliding toggles 2 and a back plate 3, wherein a penetrating feeding opening is arranged on the back plate 3, the adjusting ring 1 is arranged in the feeding opening, a feeding mouth is arranged in the center of the adjusting ring 1, a sliding groove 9 is arranged on the surface of the adjusting ring 1 outside the feeding mouth, there are in total 4-8 sliding grooves 9, which are evenly distributed on the adjusting ring 1 with the center point of the circular feeding mouth as the center and are in the shape of inclined strips. a limit cover 8 is installed on the back plate 3 on one side of the feeding opening, a plurality of sliding toggles 2 are movably installed between the adjusting ring 1 and the limit cover 8, the installed sliding toggles 2 form a ring, and the inner hole of the ring is the beak feeding mouth; a bolt 10 is arranged on one side of the sliding toggle 2 and is fitted with a limit hole on the back plate 3, a release pin 11 is arranged on the other side of the sliding toggle 2 and is movably inserted in the sliding groove 9. The sliding grooves are in a strip shape, and one end is inclined by 15-25 degrees backwards to the rotation direction with the other end as the base point. The bottom of the back plate 3 extends to one side to form a bird standing rod 5, the bird standing rod 5 and the back plate 3 are in L shape by side view, and a buckle 4 is arranged at the other end of the back plate 3 and is connected with the pipe wall of the external feeder; a clamping slot 6 is arranged on the back plate 3 at the edge of the feeding mouth, and a clamping groove 7 is arranged at the edge of the limit cover 8 and is fitted with the clamping slot 6.

[0015] There are in total 6 sliding toggles 2, and the six sliding toggles are respectively clamped in the adjusting ring and the sliding grooves of the limit cover by the bolts and the release pins on the front and back. The user rotates the adjusting ring on the rotation operating panel. At the same time, the sliding grooves behind the adjusting ring are also coaxially rotated to drive the six sliding toggles for displacement. When the adjusting ring is rotated clockwise, the six sliding toggles are in mutual contact and interact to move closer to the center, so that the size of feeding opening is minimum. When the adjusting ring is rotated anticlockwise, the six sliding toggles are driven to be diverged outwards. At this point, the size of feeding opening is maximum.

[0016] The above embodiment is only the preferred embodiment of the invention, not intended to limit the scope of implementation of the invention. Therefore, any changes made in accordance with the working procedure and flow, shape and principle of the invention shall be covered within the scope of protection of the invention.
