[0032] Furthermore, the base is provided with two slide mounting seats, which are arranged diagonally along the center of the base for detachable installation of the slide in the side hole drilling jig slide 2.

[0033] In this embodiment, the top hole drill 7 is a ring structure with several guide holes spaced apart on the ring; the size of the top hole drill 7 is the same as that of the valve cylinder 6, and after installation, the edge of the top hole drill 7 is aligned with the outer side of the valve cylinder 6.

[0034] In this embodiment, the horizontal quick clamp 4 includes a horizontal head, a horizontal handle (just a name to distinguish it from a "vertical handle" and it is not necessarily horizontally set), a connecting plate, and a mounting base; the mounting base is fixed on a mounting seat on the base, and the horizontal handle is connected to the horizontal head through the connecting plate; the horizontal handle 3.2 is hinged to the connecting plate and the mounting base respectively, and the connecting plate is hinged to the horizontal head; the extension and retraction of the horizontal head (or the clamping force) can be controlled by moving the horizontal handle.

[0035] The vertical quick clamp 3 includes a vertical head, a first connector, a second connector, a vertical handle (this is just a name to distinguish it from a "horizontal handle" and it is not necessarily vertically set), and a fixed base; the fixed base is fixedly installed on the upper fixed plate, the first connector is L-shaped, and the first connector is hinged to the vertical handle and the fixed base respectively, and the second connector is hinged to the vertical handle and the fixed base respectively; the downward pressure (or clamping force) of the vertical head can be controlled by moving the vertical handle.
