Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-5 The existing lawnmower blade holder disc is not convenient to prevent the mowing blade from sliding during mowing, and debris can enter the mowing blade and blade holder disc. In order to solve this technical problem, this embodiment discloses the following technical content;

[0027] The mounting plate 1 has a first through hole 2 and a connecting hole 3 at equal angles at the middle and outer sides, and a fixed blade plate 5 is connected to the upper surface of the mounting plate 1. The fixed blade plate 5 has several connecting holes 3 at equal angles at the middle of the fixed blade plate 5. The fixed blade plate 5 and the mounting plate 1 are fixedly connected by a stabilizing bolt 8 through the connecting holes 3. Several protrusions 6 are fixedly connected at equal angles at the outer end of the upper surface of the fixed blade plate 5. The fixed blade plate 5 has a second through hole 7 at the middle. The stabilizing bolt 8 is connected in the connecting hole 3 on the mounting plate 1. The upper and lower surfaces of the stabilizing bolt 8 are on the same plane as the upper surface of the fixed blade plate 5 and the lower surface of the mounting plate 1, respectively. The fixed blade plate 9 is connected to the middle of the upper surface of the fixed blade plate 5.

[0028] A third through hole 11 is provided in the middle of the blade 10. The first gasket 9 is located in the third through hole 11 in the middle of the lower surface of the blade 10. Several storage slots 12 are provided at equal angles in the middle of the lower surface of the blade 10. The protrusion 6 is engaged with the storage slot 12.
