Abstract
The utility model relates to a diamond-shaped positioning pin shaft which comprises a cone-shaped platform (1), a cylinder (2), a cylinder (3), a cylinder (4) and a cylinder (5) which are sequentially connected from top to bottom. The dip angle of the cone-shaped platform (1) is 45 degrees. A diamond-shaped through hole is formed in the cylinder (3). Through holes which are on a same vertical line are formed in the cone-shaped platform (1), the cylinder (2), the cylinder (4) and the cylinder (5). The height ratio of the cone-shaped platform (1), the cylinder (2), the cylinder (3), the cylinder (4) and the cylinder (5) is 1 to 1.2 to 2.8 to 1 to2.7. The diameter ratio of the cylinder (2), the cylinder (3), the cylinder (4) and the cylinder (5) is 1.6 to 1.9 to 1 to 1. The diamond shaped positioning pin shaft is simple and reasonable in structure and design and wider in adaptability.
