Abstract

The utility model relates to a small-diameter fisher comprising a rope cap (1), a body (2), an upper cam assembly (3), a fishing assembly (4), a guide body (5), a lower cam assembly (6), a guide claw (7) and a bottom plug (8). The rope cap (1) is connected at the upper end of the body (2), the upper cam assembly (3) and the fishing assembly (4) are mounted on the body (2), the upper end of the guide body (5) is connected with the lower end of the body (2), the guide claw (7) is hinged on the guide body (5), a guide claw spring (10) is arranged between the guide claw (7) and the guide body (5), and the bottom plate (8) is mounted at the lower end of the guide body (5). The small-diameter fisher can pass a scaled well pipe column to reach preset fishing position without affecting normal fishing, and success rate of fishing can be guaranteed. Additionally, the small-diameter fisher 38mm in diameter is thinner than a conventional phi44 fisher, thereby being more favorable for passing the scaled well pipe column.
