DETAILED DESCRIPTION

[0026] In order to make the technical scheme of the present application better understood by those skilled in the art, the present application will be further described in detail with reference to the accompanying drawings.

[0030] Specifically, as the central rod 4 rotates, it带动 the connecting ring 5 to rotate synchronously, causing the moving block 6 to rotate around the axis of the central rod 4. Under the centrifugal force, the moving rod 9 moves along the path of the guiding groove 8, first moving horizontally in the horizontal section 801. When it moves to the lower arc section 802, the moving rod 9 moves obliquely downward, causing the moving block 6 to slide downward inside the connecting ring 5, driving the drill bit 10 to extend out from the inside of the protective cylinder 7, and then the turbine shaft can be drilled. After the drilling of the turbine shaft is completed, the reverse rotation of the central rod 4带动 the moving rod 9 to move back into the horizontal section 801 again, causing the drill bit 10 to retract from the outside of the protective cylinder 7, preventing the drill bit 10 from being exposed outside when not driven and coming into contact with the turbine shaft or the back of the operator's hand.
