In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "disposed" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention based on its overall structure.

Referring to fig. 1-3, a PCB fisheye needle pressing tool comprises a positioning block 1 and a PCB plate 7, wherein a thick guide post 2 is arranged on one side of the top of the positioning block 1, a thin guide post 3 is arranged on the other side of the top of the positioning block 1, an upper pressing block 4 is connected to the top of the thick guide post 2, a gearbox bottom shell 5 is mounted on the surface of the positioning block 1, a positioning post 6 is arranged inside the gearbox bottom shell 5, and a positioning hole 701 is formed in the surface of the PCB plate 7.
